Stereo vision calibration failed

Hi guys,
I'm using the Calibrate stereo vision.vi (NI Vision development module 2013) to calibrate my stereo vision system but I failed and I don't know why. My experimental setup is as follows:
2 aviator 1600gc cameras, with 16mm focal lenses and a baseline of 1 cm;
a calibration grid of 16*16 dots (dx=dy=4 cm), at a distance of 2 meters;
2 light projector of 500 W.
I followed the VI instructions and made a lot of trials for 2 days, but i never succedeed in calibration. More specific, in the grid coverage control i always obtain NaN %, as showed in the picture in the attachment.
In continued to acquire images as long as all gride coverage control below are all to 100% but the VI doesn't proceed into grid vertex calibration.
Can someone help me?
Thanks in advance

Hi there,
I got exactly the same problem! I hope it's okay posting in this topic.
I followed the instructions on http://zone.ni.com/reference/en-XX/help/370281U-01/imaqvision/stereo_vision_example/ but my top grid coverage just won't show any values.
The grid is from the NI folder, so actually it should be okay.
cams: 2x DMK 23F618 from ImagingSource
lenses: 2x 8mm F1.2
Furthermore, at most attempts I won't even get any values at all.
Even if all points are detected it won't show any values. This mostly happens when I use external light sources (tried it with infrared and a common 20W halogen lamp running on DC)
I hope you can help me out here! Thanks

Stereo Vision Calibration

Hello Everyone...
Can any one plese explain the GRID Calibration procedure for a Stero Vision Application in LabVIEW along with the following queries realted to the same.
1) Would Grid Calibration will provide the 3D Position information of a Object?
2) Is it possible to prepare a test Srereo setup for Stereo Vision using USB Cameras(WEB Cams)?
3) How to confind the Field of View of the Camera to a certain Area of e.g 100x100x100 mm ?
Thanks

Stereo Vision and Projected Light

Hello!
I'm looking for examples for the technologies mentioned in the subject. Anyone has dealt with these? If yes, can he share an example about them?
I have found an example for Stereo Vision in Vision Development Module's help, but I'm looking for other ones, and so far no success finding any.

Hello,
take a look at the following discussion:
http://forums.ni.com/t5/Machine-Vision/Stereo-library-2012-pointers/m-p/2171812/highlight/true#M3672...
Also, I am attaching a set of VI's (LV2012) that I used some time ago to obtain depth image from stereo image pair. They consist of three different stages:
1. Images acquisition,
2. Stereo calibration,
3. Measurements.
When there is enough (distinct) texture on the measured surface, the projector is not neccessary. But in low texture setups, it can greatly enhance the quality of the measured data. If the projector is used, take care that the pattern is as random as possible. This should give the correlation algorithm a good basis. Take a look at the following paper:
http://www.aurelien.plyer.fr/wp-content/uploads/2012/04/ptext.pdf
About "Light Projection" - if you are referring to structured lighting techniques take a look at the following page:

Hope this helps you in some way.

Where is original point of Z axis in a stereo vision system?

Hello, everyone
I use LabVIEW Stereo Vision module. After I calibrate my stereo vision system, I want to verify the accuracy of my system. I can get every point`s depth in my picture, but where is my original point of Z axis?
In the newest NI Vision Concepts Help, it is written that NI Vision renders 3D information with respect to the left rectified image such that the new optical center will be at (0, 0, Z) position. Is the original point of Z axis is on the CCD of left camera or the optical center of my left camera`s lens?
So anyone can help me ?

Hello,
I would say that the coordinate system origin is at the optical centre, that is the camera's projection centre.
So, yes, the optical centre of the left camera's lense. This seems most logical to me...

Shunt Calibration Failed

Hello! I'm pretty new to LabVIEW so I apoligize if I am confusing.
I'm trying to put together a VI that will take the strain measurements from four gauges, initially based off of the example provided through the "Strain - Continuous Input.vi". I'm using a cDAQ-9147 equiped with a NI 9237 and a NI 9944. Since our system won't be changing I wanted to set the Shunt resistor value and location as constants (100,000 ohm and R3, respectively). Unfortunately when I then try to run the VI with "Enable Shunt Cal" on I get an error::
"Error -201493 occurred at DAQmx Perform Shunt Calibration (Strain).vi:5630001
Possible reason(s):
Shunt calibration failed. The calculated gain adjust is out of range. Ensure that the shunt calibration terminals are connected properly and that the shunt resistance and shunt element location settings match how the hardware is wired.
Property: AI.Bridge.ShuntCal.ShuntCalAResistance
Corresponding Value: 100.0e3
Simulated Value with Shunt: 1.750000e-3
Measured Value with Shunt: 603.757856e-6
Property: AI.Bridge.ShuntCal.GainAdjust
Requested Value: 2.898513
Possible Values: 500.0e-3 to 1.500000
Channel Name: Axial 2
Task Name: _unnamedTask<A>"
I should note that the original example works on all gauges, so I know it's a mistake I've made somewhere. I've included the VI if that will help.
Thank you!

Hi Sunkistist,
This error can be caused by one of 3 things:
Your 9237 is so far out of calibration that the gain adjustment it would take to correct it is higher than the maximum supported by shunt calibration. Since the shipping example works, and your confident with the readings, we can assume this is not the case.
Improper physical connections. Again, we can rule this out for the same reasons as #1.
Improper configuration. Check to ensure the all the bridge resistance and strain gauge information is correct.
Here are some links you might find helpful:

Stereo vision using commercial DSLR

Hi. I'm a Phd student in CE.
I'm going to build stereographic equipment setup using two comercial dslr cameras and labveiw.
The specific application is accurate target position estimation using stereoscopic (stereo vision system).
I know there are SDK package in Nikon and Canon for controling camera with computer. However, they don't provide multi-camera control solution so it is hard to construct it. Would it be possible to control cameras using Labview? Here, "control" means the camera control functions (such as live-viewing, zoom in/out, etc) , which are provided by commercial camera tethering software like 'Nikon Camera Control Pro 2'.
I heard that HYTEK (http://www.hytekautomation.ca/ ) made Laview VI's for Nikon cameras but I'm not sure it works for my setup or suitable for stereo vision. I hope use the software that NI provides.
Does anyone know about this topic? All suggestions/comments are welcom

dear chulminy
you can use usb camera or gige vision camera, much chiper than DSLR, and LabVIEW support those camera, you can install Vision Acquisition Software, then the camera can be config in max, and used in LabVIEW.

Apple Studio Display 21inch - calibration fails

G'day all, I've reviewed the topics on this display and none seem to fit my problem. Further, I'm convinced that it's not a display problem but an OS Tiger 10.4.11 problem but I reckon that this is the forum that will be best suited to answer.
In essence, the problem is that a get an overly white screen with very bold colours - as if the contrast and brightness is on steroids and I cannot get past the first page of the ColorSync Assistant. This condition occurred as a result of allowing a service technician to use my Mac to set up a satellite modem - you'd hope that technicians would be more responsible . . . . .
Anyhow, as I said, I'm convinced that the problem has more to do with OS 10.4.11 than the display as this works perfectly with another user. Specifically, the technician was logged in as PowerMacUser (isn't that original?) and that is the user which gets a problem display. If I log in as another user (i.e. PowerCenterUser - yes! there's one of these on the network) then the screen is normal and I can calibrate the display. So ColorSynch and the Studio Display are working.
But when I log in again as PowerMacUser nothing has changed. I did make sure that the color profiles in the Computer/Library/ColorSync/Profiles/Display were the same as those used for PowerCenterUser even though they are global, but that didn't make any difference. And I have tried to find out where user-specific data is used to modify display profiles but without success.
I have a suspicion that it may have something to do with a file named <boot> but I won't pursue this unless I have a prod to so do.

This is an update. I'm a bit impatient so I got up at 02:30 and did some more research.
I found that the file boot.efi was still in my trash (OldUsers . .System>Library>CoreServicesboot.efi) and followed BDAqua's excellent advice in regard to this (see http://discussions.apple.com/thread.jspa?messageID=11661635&#11661635).
Thus I verified both discs in the PowerMac,did a Safe boot - which failed to correct the colour problem. I then reinstalled Mac OS 10.4 - which failed to correct the colour problem and I'm now in the process of bringing this up to OS 10.4.11.
The only approach that I can think of now is to create a new user since users other than PowerMacUser (see previous post) do not experience the colour problem.
Any, more creative, ideas would be welcome.

MSE RF Calibration - Failed to initiate data collection

Hi guys.
As you know, in order to improve Wi-Fi location accuracy, we can apply our RF calibration model. I have a problem here, it is impossible to calibrate.
I'm using:
WLC 7.6.100.0;
MSE 7.6.100.0;
PI-VA-1.4.0.45-small.
I have a client with Intel(R) Centrino(R) Advanced-N 6205 wireless card. This card is CCX capable and here is my client info on WLC:
However, when I go to Cisco Prime infrastructure, create a new RF calibration model, select the floor and click “Next”:
In the new page I see this error (but I already enabled S60 setting on the WLC via CLI):
Ok... let say we click "OK" here. Next, on this page I choose “Collection Method – Point” and click “Go” on the selected Calibration Point. The new error message appears:
So in this situation, I am not able to collect any calibration data in order to improve location accuracy.
Maybe I am missing something? Has anyone of you tested this?

Hi,
I have solved this problem. The problem was incorrect SNMP configuration between WLC and Cisco Prime Infrastructure. Please check Your SNMP configuration.

Why won't BT let me have BT Vision - 3 failed orde...

I have placed 1 online order for BT Vision and 2 on the phone orders. All have been cancelled (in succession - I didn't place all at the same time!).
Apparently I live in a "red" freeview area and they won't sell me it. Even though I get every single Freeview channel in my house and am willing just to have the On Demand service if necessary. The website accepts the order and let's me agree to just have On Demand. Then they bin my order.
The website says "If you don't have access to Freeview, you can still get all of BT Vision's great on demand entertainment." But this isn't true - they won't do it if you can't get Freeview.
I've sent over 3.5 hours on the phone to BT about this. This is crazy! Plus I left my old ISP (who had a better broadband offer) for BT Total Broadband purely because of BT Vision.
Can anyone from BT help me please? This is an absurd situation. They are refusing money even when I am willing to agree to not receiving Freeview. Aaargh!
Help?

Stereo vision using 2 sync'd ps3 eye

Hello too the whole forum!
I'm new to archlinux and i've been trying to make use of a synchronized pair of ps3 eye webcams. The hardware has been confirmed to be synchronized but i've been unable to make that usefull on the software side. I'm using OpenCV libraries, programming in python and have tried, unsuccessfully, to use the mkoval solution ( https://github.com/mkoval/stereo_webcam ).
Has any of you had any experience with it? If so, what have you done to make it work?
Nice to find such an active comunity here!
Thank you and have a nice weekend!

You can do this under the same computer login account or with another computer login account.
Doing this under the same computer login account will require having to log in and out of each iTunes library depending on which one you want to use for syncing, etc.
Doing this under another computer login account will require having to log in and out of each computer login account depending on which one you want to use for syncing, etc, and with OS X there is fast user switching making the process of switcing between multiple computer login account fast and easy. One way is probably not faster than the other.
How about making use of iTunes playlists with one iTunes library? There is no rule that your entire iTunes library must be transferred to an iPod or iOS device.
