Hi @JanKanka
Whn flashing the device, the standard sensord values are used to provide a baseline to perform calibration on top of it. It used to be that the specified FOV was more accurate than the calculated one (calibrated). They are both saved in the eeprom but useSpec lets you select which one you want.

Hi @JanKanka
MAX fov will be 108 at 12MP. Intrinsics should be calculated for 12MP since they are sensor based. Use spec should be set to false otherwise the specified fov will be used, not the calibrated one. Eeprom also has the spec FOV, thats why the 108.

Thanks,

Hi @JanKanka
How are you getting the rectangle. The way scaling works for 720p is ISP (12MP) --> crop to 4K (3840*2160) --> scale down to 720P (same aspect ratio, so no cropping).

Hi @JanKanka
No built-in function. But you can calculate it with np.rad2deg(2*np.arctan(VIDEO_W/MAX_W * np.tan(MAX_FOV*2*np.pi/(2*360))))

Thoughts?
