Using yolov3 & yolov4 weights objects are being detected from live video frame along with the measurement of the object from the camera without the support of any extra hardware device.
I have the same question... also it seems f should be different from camera to camera, but it seems the final formula used in utils.py used constant f.
I wonder how this {d = f + R/r} formula came out. Does d mean do? Or does it mean oblique distance?
