Motorized focus calibration #24

Open Wengorito opened 4 years ago

Hi, is there any function relating the parameter 'focal_distance' with an actual distance of objects in focus? I am wondering if it is possible to utilize this camera to measure the distance.

Of course it can be done by experimental calibration with some test chart, but depth of field of this camera is rather huge. Has anyone tried?

Thanks in advance
