Has someone here ever made a DIY LiDar from scratch that can 3D scan? If yes, can you give an explanation regarding the process of doing so?
If you offset two photo_receptors by a known distance, and illuminate a target with a photon source, the output of the 2 photo-receptors will differ
by a logarithmic amount. And you can extract DISTANCE from that. The usual (RANGE * RANGE) dropoff in detected_signal will still occur, but the fixed distance offset gives you a &quot;calibration constant&quot; in your two channels of math.
This method does not require any timing, just approximately_matched detectors.
You will find blurring in your measurements, because you are constantly scanning the laser beam.
If I get a chance during the day, I'll return and provide the full math for this.
