Kangaroo using GRIP and Lifecam HD-3000 Not Working
 
We just got our Kangaroo that we are planning to use to run GRIP for onboard vision processing in the mail yesterday. After booting it up and firing up GRIP, the camera worked momentarily with the pipeline we had tested on our other laptop, then it ceased to work and has ever since, despite my attempts to uninstall/reinstall drivers and to try to get an old driver (but I have not had luck in this department yet). The webcam still works with the native Windows camera app however. Others have had the same issue, and there is even an issue open on GitHub here. My suspicion, as with others, is that the driver is too new for the OpenCV build being used by GRIP, which is somehow causing it to throw an error. One user claims that installing an older driver fixed the issue for him, but he didn't specify what version of the driver he reverted to, so I have no idea what driver I should be looking for. Has anyone here ran into this issue as well? Any help would be much appreciated, as the Kangaroo is a super sweet little device that I'd love to be able to use for vision processing. Thanks! :)

There should be a file called GRIP.log in C:\Users\<user>\GRIP\. If you're using version 1.5.2 it would be helpful to post that log file.

Here's the relevant output from the GRIP log file:

Definitely looks like the same problem. Googling around for LifeCam drivers comes up with a few results for old drivers you could try, though I can't guarantee that they'll work or not be malicious.

We had this exact problem and I can attest to how frustrating it is. The camera light comes on just long enough to make you think it's going to work this time and....not!

We reverted back our Lifecam drivers until we got to 4.25.532.0 and it solved the problem. I'm not at the Kangaroo so I can't past the link, but it was a third party driver site and not Microsoft that we had to get it from. If you can't find it I'll post the link tomorrow.

Good luck!

Thank you so much! I'll try to find it, but if you could post the link here that would be great (especially if others have the same problem).

Here you go. We downloaded the driver from Softpedia (link). That being said, I just noticed we're running version 3.6.250.0 of the driver on the Kangaroo now. If you can, just get that one. I'm pretty sure both work, but that one is serving us well now. The driver's dated 12-2-2010.

If you have any problems downloading, installing, etc. just let me know. I can just send you the cab file if you need. Once you have that file downloaded then to through Device Manager, select the camera, and use the "install driver" button to find navigate to the cab file you downloaded.

If the camera stops working for any reason (it only happened to us once), just check the driver as Windows may have just replaced it again.

Any problems let me know!
