Difference in initial seetings between devices?
Hi all!
I have a question concerning the settings of a D435 camera.
I have a computer vision program made with opencv(c++) and a D435 RealSense camera. I use a PC to do all the programming and debugging, and a SBC to eventually run the program when in use.
My problem is that, with the same settings, the image created by the camera is a lot lighter on the SBC than on the PC. This causes problems with the vision system, which requires debugging on the SBC.
The PC runs on ubuntu 20.04, with librealsense v2.49. The SBC (Nvidia Jetson AGX Xavier) runs on ubuntu 18.04, with librealsense v2.50.
Could the difference in brightness be caused by the different realsense library version, or does the different ubuntu version change some kind of setting?
I checked al the settings in the program, the lighting of the vision is the same in both frames and the program is exactly the same on both computers.
Does somebody know what can cause this? Thanks!

Hi Lschreurs25 If you are not applying custom values to settings then the default values for a particular camera model should be the same no matter which computer / computing device or OS is used with the camera.
Using different librealsense SDK versions on your development and test computers would open the possibility though that the output might vary depending on what added-feature or bug-fix changes had been made in the newer version.
You could test whether the Ubuntu OS or the kernel is an influencing factor by building librealsense from source code with CMake using the RSUSB backend method, which is not dependent on Linux versions or kernel versions and does not require patching. Instructions for an RSUSB build on Jetson can be found at the link below.
