Near Field iToF LIDAR Depth Improvement from Limited Number of Shots
Indirect Time of Flight LiDARs can indirectly calculate the scene's depth
from the phase shift angle between transmitted and received laser signals with
amplitudes modulated at a predefined frequency. Unfortunately, this method
generates ambiguity in calculated depth when the phase shift angle value
exceeds . Current state-of-the-art methods use raw samples generated
using two distinct modulation frequencies to overcome this ambiguity problem.
However, this comes at the cost of increasing laser components' stress and
raising their temperature, which reduces their lifetime and increases power
consumption. In our work, we study two different methods to recover the entire
depth range of the LiDAR using fewer raw data sample shots from a single
modulation frequency with the support of sensor's gray scale output to reduce
the laser components' stress and power consumption
