Hardware Implementation of a Centroid Extraction Algorithm for Laser Imaging Based on FPGA

An adaptive centroid extraction algorithm module is described. This module includes three sub modules, which are adaptive integration time adjustment, smoothness processing of multi wave crests, and extraction of centroid based on gray weighted. This module is realized on FPGA with small delay and little resource occupation. Stable extraction of centroid in the detector imaging system is beneficial to improve the dimensional precision of laser ranging.
