Automatically wait for AF adjustment to complete then snap photo

glitchyordis

Hi, let's say we triggered OAK-D PRO to change autofocus (AF) mode ctrl.setAutoFocusMode(dai.CameraControl.AutoFocusMode.CONTINUOUS_VIDEO).

Is there a way to ask OAK-D PRO to tell us once it is done adjusting the AF? The idea is that our python code waits for the camera to complete the adjustment, once OAK-D is done our code gets the new isp_data.getCvFrame().

Hi glitchyordis ,
You could check isp_data.getLensPosition() (isp_data is ImgFrame message) - and if it hasn't changed eg. 5 frames in a row, this likely means that AF has converged. Thoughts?
Thanks, Erik
