I need use a webcam in labview, is it possible?
BYEE!!!

I haven't tried this, but here's a page with some info and VIs to download.

A Google search on "webcam +labview" will probably return other pages.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

How can i use activeX Control in labview?

how can i use activeX Control in labview?
please describe me step by step.
thanks.

Well..that was quite helpful..but now I'm encountering certain problems. I've attached the VI I've made.
I don't need sound at the moment so I dropped it. (Although I tried to play it..but all I could hear was a very annoying sound.) Secondly I don't want to display any date or time..so i dropped that property too.
Now when I run this Vi...the webcam turns on, the screen of videocapx pops up..then the webcam light goes off..and another pop up appears saying..labview is not responding..and i have to close it reluctantly.
I haven't placed the stop capture property in this vi. i checked it by placing it too..but that doesn't work.
I would like to notify that my actual task is to acquire image and then compare it with another one already present on my pc. I want you to please help me out..solve my first query then I'll proceed with the latter part.

How to use a webcam with Labview8,Vision 8 in motion tracking?

I have a webcam and Labview 8, Vision Assistant Module 8, NI IMAQ for USB Cameras. What I concern is how to use a webcam in motion tracking? Should I just use Vision assistant or use it in combination with Labview? Do I need any other support?

4,
Thanks for your post. Vision Assistant is a good software package to prototype your system, but it does not give you access to all Vision methods. LabVIEW is much more powerful allowing full access to Vision. You may want to use Vision Assistant to play with the algorithms (you can use your mouse to set regions of interest, etc) and then once you find the methods and parameters that work, implement the code in LabVIEW.

Acquire Images from webcam in LabVIEW 8.5

I've been working with Labview for week now and have done several
online tutorials and things like that. I need to be able to record an
image from a webcam into Labview. I've found numerous discussions on
the topic but none that contain any solid examples. I have Labview 8.5
with the NI-IMAQ drivers and NI Vision.
What
are the basic steps that need to be done to aquire an image from a
webcam and display it on a front panel? Any example VI's or detailed
descriptions would be more than welcome. Please understand that I have
just started working with LabView so some concepts like device drivers
are still a little new to me. Thank you for any help you can provide.

Hi CanadianKyle,
I've been working with Labview for few months now and have done several online tutorials and things like that.
but i can not tell you exactly that Vision requirement is must or not?......
But I Think there is no other way to use this without Vision 7.1 or Higher.
U will get Vision with evaluation version on Ni.com.
You can try for this, It will help you.
best luck.

How do i use my webcam and photo on my dktp4/500

If you want to connect and use an iPod on more than one computer you need to change the update preference in the iPod Summary tab to "Manually manage music and videos" and click Apply. In this mode you just drag and drop whatever you want to the iPod from either library. You can also access and play the songs on the iPod through the computer in manual mode so you don't need to have the songs physically on both machines (Note: iPod shuffles are only designed to be used with a single library or computer):
Using iPod with Multiple computers
Managing content manually on iPod
iPod 101: Fill 'er Up
Note: When changing from automatic to manual, check the "manually manage music and videos" box in Summary then press the Apply button. "Don't" uncheck Sync Music in the Music tab, it will be unchecked by default when you choose the manual setting, if you uncheck it without setting the iPod to manual first you'll erase all the songs from your iPod
Something else to be aware of when using an iPod in manual mode is that the "Do Not Disconnect" message will remain on the display until you physically eject the device. In that case use Safely Remove Hardware icon in the Windows system tray on your desktop or check this link: Safely Disconnect IPod

How to implement a dual booting PXI system using windows 7 and labview RT

Good Day
My name is Mariano Ocana from the University of Manitoba, and I want to implement a dual system using windows 7 and labview RT in a PXIe-1082 chassis with a PXIe-8102 embedded controlled (the chassis came with windows 7 installed). What are the steps to use both systems (windows and RT) in the same chassis?, in the NI help comes an example implementing a dual system using windows xp and RT, it is the same procedure?.
Thank you in advance for all your help.
Regards
M. Ocana

Greetings, Mariano.
The real issue you have to contend with is whether or not you have a LabVIEW RT license. If the 8102 controller was purchased Windows-Only, you likely do not have a license to run LabVIEW RT on the controller - you can purchase one, I think it's about $500, and at that point you can request a LabVIEW RT Configuration CD (that's not what it's called, but the sales guy will know what I'm talking about). The Config CD is a CD that will partition your controller correctly with both FAT32 and NTFS filesystems (in the appropriate way) to allow you to run Windows 7 and LabVIEW Real-Time on the controller correctly. Once done, you can then switch within the BIOS between LabVIEW Real-Time and Windows in order to dual-boot.
Either way, you likely need to contact NI sales to either purchase an RT license (if one was not received at the time of purchase) or to request a Configuration CD (it might also be called a dual-boot install CD or similar).

Getting the data in file using DAQ assistant in Labview

I am using SCXI 1000 chassis, SCXI 1125 input module and SCXI 1320
terminal.
I am using DAQ assistant in labview to obtain temperatures and store it in
a file. The experiments run the whole day and I need the whole data
generated during this time to be stored in a single file, but I am unable
to store it in a single file.
Can someone please give me some insight as to how can I achieve this?

Hi Mr,
It would be helpful to see your code to see exactly how you are acquiring the data. Are you doing continuous buffered measurements? Or are you performing single point temperature measurements in a while loop?
Either way you will want to use the "write to spreadsheet" VI in your loop. Simply wire your data into the "write to spreadsheet" vi and se the "append to file" input to TRUE. This will make the data add on to the end of the file with each iteration of the loop. The "write to spreadsheet" VI is located in the file IO pallette in LabVIEW.
Thanks,
Sal

you need to increment the "accumulator increment" during the duration of the chirp. the "accumulator increment" controls the frequency of the DDS cycle. by increasing it's value, you are increasing the frequency. the math for increment values follows the same math as determining the frequency to increment value.

HT1338 how to use a webcam in a mac pro?

How to use a webcam on a mac pro?

Generally, plug it in.
The OS should notice most major webcams, although you might need to install some software from the vendor to make it work. You'll need to check specific make/models for compatibility.
Once it's connected it should be available in any application that supports video input.

Can't start video, try closing other programs that might be using your webcam

I am using skype on win8. It was perfectly fine until last week. This message "can't start video, try closing other programs that might be using your webcam" is always there. I investigated this problem in the forum. I did this but it did not help at all. I checked nothing was using webcam! Try to reset skype settings Exit Skype : From the system tray >> right click on the skype icon and click "Quit Skype" Click Start >> Run Type: %appdata% Rename folder "Skype" to "Old_Skype" Re-run Skype
I tried some other chatting software and it gives me the same problem. However, the metro app camara is working perfectly fine. I have the latest driver and I also tried another webcam from logitech and it gives the same problem!!!!

Most likely this is one of the registry keys that need to be modified. However, be very careful when you make any changes to your Registry Database. Make always a copy of this data base before making any changes, so you can always revert to the original settings if something will go wrong. The relevant keys are these that refer to Imaging devices. On my system I have 3 such devices: Logitech c920 webcam, LifeCam VX-5000 webcam and CanoScan LiDE 25 Scanner. The last is installed but not currently connected to the computer. You can make a search in your registry database using this item: imaging devices. For all the items I could find on my system, the main key of the type, HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00X\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F} was looking like this: There is neither LowerFilters nor UpperFilters value defined. You can open the subkeys of the type 0000, 0001, 0002, etc. and see what device they are referring to.

Using the webcam with MSN

When I bought my Macbook I thought I would be able to use the built in webcam on MSN Messenger, but after three months I am still failing to find a way... Is it possible, or is the webcam only compatible with iChat?
Thanks for you help!

there are a few ways for ichat... such as a .mac account (you have to pay as well as the other person needs a mac with .mac account too), you can use AIM on ichat.. and the other person (PC user) just needs an AIM account as well... there is a chat program called skype.. which you both would need.. and another one that i know is using jabber in ichat.. there are many steps to set up jabber to function as msn and you get to use the webcam function

Controling wheelchair by speech command using Neuron Network in labview

Hi all,
I'm doing project about "controling wheelchair by speech command using neuron network in labview". I found some informations about controling whelchair combine with function microsoft speech recognition in window or something like that but this was not my point. So, I have some question about that:
1) How do I store the command "Left-Right-Back-Go-Stop" in labview. After that, analyzing to find the differences of characteristic of these command.
2) Based on these characteristic above, using neuron network to find exactly command.
Are there anyone do like this before? I need all help from you.
Thank you so much.

Greetings;
First, it is most excellent that you have gotten to where you can compare the words being said to the sample.
If I understand correctly, you are interested in continuously acquiring sound, saving it and then comparing it with the sample? That is not as straightforward as it sounds simply because it would be difficult to realize when there is sound in the first place and when that sound is relevant.
I would probably start by figuring out whether there is or not sound by comparing the microphone input to a certain threshold, saving if there is sound, and then halting the recording when the sound stops. It would be then that you would compare with your samples via the algorithm that you have made.
In order to check for volume, I came across the following example:

It was mentioned in the following discussion:

Using cin node in labview error happen

my name is Juan Chen , I wish to use cin node to calculate crc check code in la view. I use an array as input and a unsigned word as output. when I use while loop, error not enough memory or the memory can only read happen. what is the reason,please.

how to use the call library function node ? in vcplusplus6 environment , if I only do rebuild all that can generate a dll, and don't use command to convert to lsb file. could I need add files cin.obj, labview.lsvb,etl to the project ?

Using Shared Memory in LabVIEW

I'm trying to use shared memory with LabVIEW. Can I use it, a DLL in C with LabWIEW for use shared Memory?

Lidia,
Check these out (for memory mapping):

But in general you don't need to use this when you use dll's. It is used to
share data between different processes. If you need LabVIEW data in a dll,
try to pass it as a pointer to an array, or as a string pointer.
Regards,
Wiebe.
