Pink color in the ZED one GS stream

Hi,

i am using a zedx one gs no lens camera and i fit EDA lens EDATEC ED-LENS-M12-230390-08 8MP 3.9MM M12 RASPBERRY PI LENS but the stream is pinkish … is that because of the lens or there are some parameters which i have to tweak?

also when i try to launch using the ros2 node it logs calibration file corrupted but the zed_explorer does open the pinkish feed

Is the optics equipped with an IR filter?
Normally, pinkish images are caused by an oversaturation of the RED channel because of the IR component of the sunlight.

ZED Explorer does not search for the calibration file because it shows the raw unrectified images.

You must use OpenCV to calibrate the camera and generate a YAML calibration file to be opened using the parameter sl::InitParametersOne::optional_opencv_calibration_file:

Normally, our cameras are calibrated in the factory, but this is not possible when they are sold with no optics.

I changed the lens and now the pink issue is vanished … it was a lens issue ..

Thanks !

This means that the camera is not factory calibrated.

This is expected if you bought a camera with no optics.
