Multiple Kinect v2 Sensors
Greetings,
It's been a while since anyone has heard an update regarding being able to use multiple Kinect v2 sensors on a single computer. The last I heard was in June, when supposedly an engineer said it was "3+ months away". I was wondering
if someone would be able to update the community regarding this functionality's status? I'd really like to be able to do this for a project I have in mind that would require multiple sensors and different angles and don't have the budget for a dedicated computer
for each sensor. Thank you in advance for your response, all of you are awesome!

I've been pricing builds on Newegg that I could turn into a small Kinect cluster. I need three for what I want to do. this is what I have right now. It's going to be a while before I can build up three grand so I don't know if I'll ever
get to do it. But on the bright side I would be able to use it as a cluster for other projects as well, so...yeah. I was thinking i5 but the linked conversation is deterring me from that. Would you be willing to let me know some more of your system's
specs? Would love some input from anyone willing to offer any!

Multiple Kinect 360 sensors in v2 SDK?
Hi,
therer are several threads pointing out that there is no way of using multiple v2 sensors on the same machine due to PCI bandwidth limitations.
However, I would like to use multiple v1 sensors instead. I'm about to move form OpenNI to Kinect SDK since former is discontinued and I'm hardly on Linux anyways. I have several multi-Kinect applications and I would like to port the
image acquisition code, but for that I would prefer using the most recent SDK.
Do I have to downgrade to K4W v1.8 for what I'm trying to do?
Thanks,
RolandThe v1 will only work with SDK 1.8, whereas the v2 will only work with SDK 2.0. Using multiple v1 on one PC is fairly straightforward but you need to be using the 1.8 SDK.

How to prevent interference between multiple Kinect v2 sensors
Hi,
I have an application which used to use 3 Kinect v1 with partially overlapping field of views to have a large field of view of a scene. I am trying to upgrade this application to be able to use 3 Kinect v2, as the Kinect v1 is now discontinued.
I am having problems dealing with interference on the depth stream. Every now and then, the light from one of the Kinect will give bad readings on another Kinect... This is not new, the Kinect v1 had interference problems too.
To solve the interference problems with the v1, I used to simply toggle the IR emitters ON and OFF. Since my 3 Kinects don't need to acquire a frame at the same time, 2 of them would turn their emitters OFF and the one Kinect that would need to acquire a
frame would turn its IR emitter ON.
Now, since we can no longer control the IR emitter directly, can any one give me a good solution for preventing my Kinects from interfering each other ? My Kinects don't need to acquire a frame at the same time, but they may need to each acquire a frame
on a short interval (about 100ms), so closing and opening the Kinects is not an option as up to 2 seconds can pass between the call to KinectSensor.Open() and the first non-null depth frame.

Is it must to have Kinect device/sensor to use Kinect SDK ?
Hi,
I have an image having a person in it. The image was taken from any digital camera or any WebCam.
My task is to find Person's height, and different sizes of his body measurements eg: size of his Neck, Waist, Calf, Ankle, Wrist, and Length of: His total height, Right shoulder, left shoulder, Hips to floor, Hips to Bust, Waist to Knee, Waist to Floor,
etc...
Can I use Kinect SDK for this purpose ? I am again repeating, Can i use Kinect SDK to find above mentioned measurements from any given image ? (Without having Kinect device/sensor)
I am using Windows 8 with Visual Studio 2012. Please suggest.
Regards,
Zia.The short answer is no.
You''ll need a Kinect v2 sensor, actually body detection and tracking is done purely using the depth data and does not use the color stream at all for this.
In theory you could create your own algorithms for detecting and tracking humans purely based on video (probably from multiple angles). But even with libraries like OpenCV and advanced knowledge of machine learning algorithms this will be a difficult
and time consuming task at least.

Multiple kinect V2's where there field of views dont overlap.
I know that similar questions like this have been asked before so bear with me. I want to get 2 kinect V2 sensors running on one PC. These 2 Kinect v2 sensors will be mounted on the same machine but one sensor will monitor the infeed
of the machine and one will monitor the outfeed. Then each PC will pass depth data to a PLC over ethernet for processing. It seems a waste to have 2 PC's running when I know that 1 PC can handle the info from both sensors. The sensors
will be looking in oppsite directions so the depth data coming from each sensor should be clear. Any ideas?I know that similar questions like this have been asked before so bear with me.

Connection to multiple Kinect V2, NOT for synchronous acquisition
Hi all,
I would like to connect 4 kinects v2 to a PC.
I've read that the BUS is limited and it is not possible to run multiple sensors at the same time.
In my application I need to collect the data from different points of view, but not with a synchronous acquisition, and use a single PC. Example: connect to sensor 1, acq data, close connection, repeat the same for the other sensors and then back to
1.
I wonder if this is possible playing around the pointers to the sensors and the call:
HRESULT hr = GetDefaultKinectSensor(&m_pKinectSensor);
Any suggestion?
TnxHi HalphaPk1,
I would also as Oren
Physihome much appreciate some elaboration from you how did you manage do enable/disable usb to switch between kinects.
Thanks in advance! -
Kinect V2 Sensor - Device Cannot Start
Greetings all!
I have a standard HP desktop running a fully updated Windows 8.1, plently of RAM, with a Renesas USB 3.0 adapter.
I have powered up the Kinect V2 and plugged it into the USB 3.0 adapter (there are no other devices on this USB hub).
While programs like Kinect V2 Studio start up just fine and "connect" and "monitor" don't give errors (you can see the clock ticking away), I'm not seeing anything in the monitor window.
So, looking at Device Manger, I see "Device Cannot Start" for the "WDF Kinect Sensor Interface 0" and, of course, the icon in Device Manager has the deadly yellow exclamation mark. (Also: "Current Device Power State cannot
support his request").
The Renesas USB 3.0 adapter board has a SATA power plug so there's plenty of power to the USB port.
Can't see what's wrong. Wish that Microsoft had a 'verification' app that would help troubleshoot the box.
Any ideas??

Kinect V2 Sensor for windows shutting down automatically
hi there,
Just want to ask if this a problem with hardware or my laptop.
I am testing it with Kinect V2 Configuration verifier. The video stram hangs every couple of seconds. Seems like it is restarting ( the light keep turning on and off automatically while straming Depth and color Stream).
My laptop has USB 3.0 but configuaraion verifier says "suppoer USB 3.0 port detected with unknown bandwith."
any idea ?

Products
Have been an iTunes person since 08. Have not changed this original Id which is a yahoo email account that is tied to the purchasing card for apps music etc.
2 iCloud Id's
Bought an iphone4 3 months ago an have updated it to the latest iOS 5, first iCloud I'd
Have an iPad 2 updated to latest ios 5, first iCloud I'd
Just bought for my daughter a(minor) a touch. Updated with ios 5, second iCloud I'd
Now the questions are:
Would like to use only one iTunes account (apple I'd) for all purchases tied to one PC
The iPad and iPhone are for one adult. Would like to share apps between them. But also keep them separate as the iPad is more work related but would like flexibility to pull down movies purchased by account for viewing etc
The touch would be able to have it's own apps and music but be able to be sensored by adult but also be able to pull down movies music that may be shared.
Also would like to be able to FaceTime across these three devices seperately.
Help is appreciated!Continued the search and found this article.

2011 imacs multiple hard drive sensor failures
I work at a call center where we have over 200 2011 imacs. Lately, they have been coming up with the ? on the folder (hard drive issue). The drive cannot be seen in disk utility and when running a diagnostic on it, the error code that comes up mentions the hard drive temperature sensor failure.
So far, in the last 3 weeks, we've had at LEAST 12 machines go down with this. The machines we have are the 500gb drives -- not the 1T with the recall. Is anyone out there having this same issue?
Also -- do you know of some kind of bug/script, etc that might cause this?
Usually, it happens logging onto the Open Directory Domain -- they are able to put a password in, then, the screen flashes white and when it comes back up, has the folder with the question mark on it.
Outside of sending them in for repairs -- any ideas?
Thanks.This topic is interesting because it may indicate a general problem on some Mid 2011 iMacs.
Unfortunately, when the question mark appears at startup, the hard drive is damaged, and more when Apple Hardware Test reports a problem with the hard drive fan sensor. There isn't any other solution different to take the Mac to an Apple Store or reseller to get the hard drive replaced.
I haven't noticed problems with Mid 2011 iMacs hard drives looking here. Maybe one user may come here with a Mid 2011 iMac and report the same problem, but I haven't heard anything about a generalized problem. My advice is that all people with problems with their Mid 2011 iMacs hard drives call Apple, so they can take note of the problem and launch a replacement program, if Apple considers this necessary -
Is it possible to turn off the infrared emitter without closing the sensor
Hi,
The Kinect v1 SDK had a function ForceInfraredEmitterOff(), which could be called to turn off the infrared emitter without having to close the Kinect. This was very useful for applications using multiple Kinects as it provided an easy way of preventing interference.
I am using 3 kinects with overlapping field of views to create a large field of view for a project and I would like to be able to control the infrared emitter like I did with the v1.
I looked in the SDK documentation and on the web, but found no method that could do what I want. So, did I miss something ?
Thanks.That is exactly what it means: to have a system using two Kinects you will need two computers with two Windows 8 licenses (one each), one communication path between these computers (TCP/IP seems like an obvious choice) and some way to make sure they don't
interfere each other...
As far as Carmine answer goes, it is not satisfactory: OK, I understand that my Kinect is shared by all the applications running on my computer .... MY computer, meaning that I know which applications need the sensor and which ones don't (unless some unknown
background program is spying on me.... wouldn't want to shut off the IR to prevent that program from working now...)
So, why not give programmers a way to shut off the IR and if someone runs many programs on the same computer and does not want to shut off the IR then they just don't call that function ... this way everyone is happy.
SO, in the end here is the solution my company decided to implement: we used to put 3 kinects on each of our system to have a very wide field of view. This year we plan on selling about 75 of these systems, that would have meant buying 225 Kinects. Now,
since we can't turn off the IR (a functionality that would take any programmer about 10 minutes to implement by the way), we will buy only 75 Kinects (one per system) and mount them on a linear axis. It is acutally going to cost less money to buy one linear
axis and move the camera instead of buying 3 cameras with 3 computers with 3 windows licenses and developping some sort of anti-interference solution. -
Maximum number of Kinect for Windows v2 Cameras on one PC?
There is a question about the previous iteration of the Microsoft Kinect for Windows (no longer on sale) here: https://social.msdn.microsoft.com/Forums/en-US/63c7c52e-1290-452e-8e04-74330822d16f/maximum-number-of-kinect-cameras-on-one-pc?forum=kinectsdk.
How many Kinect for Windows v2 sensors can be used on a single PC? And if this is limited to 1, is this a software, or a hardware restriction?Are there plans for this to change, or be lifted?
No. No product roadmap anyway.
The reasoning requires you to look at it from an engineering standpoint. The Kinect uses a lot (more than half) of the available bus bandwidth to operate normally. So even though you could physically connect two or more sensors, there is no feasible
way to have them both sustain enough of a data rate for them to operate normally using the existing hardware.
I'm no hardware expert, but from what I have been told, the solution is harder than just having multiple USB 3.0 controllers in the same PC.
As for "plans for this to change", rest assured that people want this, and that there are clever engineers thinking about solutions, but due to technical limitations, there is no product roadmap yet that allows for multiple kinects sensors on a
single PC. And because of the technological limitations, it will never just be "lifted". The hardware needs to change for this to work.
Another thing to consider is that, from a physics standpoint, Kinects
do interfere with each other (slightly) when operating in the same space. It's not at all dissimilar from two people trying to have a conversation in the same room -- some words of the conversation will be missed. The more people in the
room, the more difficult it is to hear one another. For the Kinect, the quality of the depth results, for example, is diminished by having two kinects operating in the same space, but the visible light cameras continue to operate unimpeded. The
sensor is cleverly designed to "tolerate" the light patterns from other kinects, but they can't completely ignore those patterns and conflicts do occur -- so it
does degrade slightly with noise from each additional sensor. It's using invisible light, so the problem tends to be "out of sight, out of mind" for us as users. But at some (modest) limit, it becomes mathematically impossible
to multiplex the light patterns from additional Kinects using the current specs (somewhere around 16 kinects based on the patterns, IIRC).
So there are other physical and technological hurdles to overcome with operating multiple Kinects in the same space, even if they were all connected to different PCs connected in a network cluster or something like that. -
Kinect protection - Can it be built in a Panel PC
hi
I have some questions regarding Kinect and its certifications and brand protection.
We are developing medical grade software (http://www.adora-med.com)
Can Kinect V2 sensor be embedded in a case or panel PC (such as Kiosk implementation or similar).
What kind of certification where made with Kinect V2 (CE mark, etc... can it be used directly in sterila area), I tried to find it on the web site, but was unsuccessful...
Best
Kristjan
Kristjan http://www.adora-med.comIf you have not found anything on the Microsoft website, then that information is not available.
http://www.kinectforwindows.com
Based on this thread: there are no restrictions for reselling the Kinect for Windows sensor. The EULA authorizes commercial usage as long as its usage falls into the terms outlined.
https://social.msdn.microsoft.com/Forums/en-US/77c0625b-913f-464d-9b52-bc8b89b994f5/selling-the-kinect-v2-as-part-of-a-robotics-product?forum=kinectv2sdk
You will have to have your legal team review the EULA and determine if that is something you can use.

i haven't used kinect sensor v2 from last 1 month, When i brought sensor it working fine. I am using kinect v2 sensor.At first time make ensure configuration are fine .It working as expected. After month i try to use it again i got update config error.
When run kinect evalution software device turn on/off for every 1s. I have gone through below link. I found kinect need to update firmware which device get update automatically. first i kept device kinect for hour so device firmware get update automatically.
later i gone to device manager,check Each sensor are upto date or not. \
It says all sensor are up to date.
I also tried kinect SDK v2.0 re install,below error continue. Please let me know what process need to be followed
sensor connect & disconnect every 1-2S approximately, whenver connect; verify depth & color will be highlighted green indicating fine & viseversa

Kinect V2 for windows sold out almost everywhere - is the product being continued?
Hi,
I would really like to get a Kinect V2 sensor for windows, but in the MS store of my country (the Netherlands) it is sold out. It is also sold out in pretty much every other european country. I only found some in the Canadian and Australian store.
Contact with the canadian store thaught me they do not ship to other countries and I should get it though the MS store of my own country. The MS store of my own country told me it's sold out, and told me it will not be 'in store' any time soon.
So my question is: why is this? will the product be produced and sold again or is it not being further developed / replaced by something new? ... if it's not discontinued, where/how should I get it?
Thanks!Hi Carmine, thx for your reply. I see I can indeed order the Xbox One sensor and the adapter, both are still available, that's great!
My only remaining question then is: as a developer, will I have the same possibilities with this combination as with the sensor for windows? (sinse with the sensor for windows it is named a 'developer kit')
EDIT:
sorry, already found the answer in the blog post about the adapter:
"With the adapter, all Kinect v2 sensors—Kinect for Windows v2 and Kinect for Xbox One—perform identically."
So I'm ordering one :)
thx!
