Hi all,

I am a bit new with the recent SDK is there anyway to rotate the stereo cameras 180 degrees in software or configure files or resources to read up on this? Currently, I realized the stereo cameras are flipped upside down checking them in the VOXL Portal. Bottom is the ceiling and top is the floor 

Thanks,

Jeff

@Jeffrey-Mao 

I am assuming you are asking about VOXL2 with ov7251 stereo in combo mode (using a single 4-lane camera port)

Please check in `/usr/lib/camera`, you should see two `com.qti.sensormodule.ov7251_combo*` files. you should remove them and replace them with ones from `/usr/share/modalai/chi-cdk/ov7251-combo-flip`, making sure you copy the files with the same camera slot index (the number at the end before `.bin`). Then simply restart `voxl-camera-server` and the cameras should be rotated 180 (this happens by reversing the direction the images are read from the camera itself, not rotated in software)
