wrong camera id for stereo camera? #63

Closed Changliu52 closed 6 years ago

Changliu52 commented 6 years ago

Hi, I have a pair of UI1221LE-M camera connected to Nvidia TX2. I launched the camera node with camera ID 1 and camera ID 2. It can only find the camera ID 1, with the second one throwing the error: 

[ERROR] [1512988231.806693548]: Could not open UEye camera ID 2 (IS_CANT_OPEN_DEVICE)
[ERROR] [1512988231.806888683]: Failed to initialize [cam1]

Also the camera ID seems to related to sequence of which camera plugged in first. So what do I do to ensure the camera I launch is the correct one?

I have also read about https://github.com/anqixu/ueye_cam/issues/48, However I don't know how to run 'ueyecameraconfig' to set camera ID. I don't see any application in such name and terminal complains command not found.

Please help.

Chang

Hi Chang. It sounds like you might have an issue with USB bus contention (i.e. too much data/power throughput on USB bus; and/or poor cabling maybe).

As you read from #48, I suggest you use the non-ROS camera binaries provided by IDS to first make sure that it's not a physical issue with your setup. Assuming that you installed the Linux ARM 64bit hard-float drivers (e.g. uEyeSDK-4.90.00-ARM_LINUX_IDS_AARCH64_GNU.tgz), you should be able to find the tools idscameramanager and ueyedemo in /usr/local/share/ueye/bin. I guess part of the issue you ran into was that ueyecameraconfig was renamed into idscameramanager... By the way, these tools should have been simlinked in /usr/bin, so for example you should be able to run the camera GUI by:

Great! Thank you very much @anqixu . I did used two separate usb ports (USB3 and USB2 OTG) I ran idscameramanager and saw that the both camera has the same camera ID 1 by default. I was able to change the camera ID in idscameramanager and everything worked.

Thank you again for your help.
