Light-spot image processing detection system and method for detecting light-spot gray scale centroid and conventional gray-scale image-noise removal effect

A light-spot image processing detection system and a method for detecting a light-spot gray scale centroid and a conventional gray-scale image-noise removal effect relates to a light-spot image processing detection system and the method for detecting the light-spot gray scale centroid and the conventional gray-scale image-noise removal effect. The light-spot image processing detection system comprises a power supply, a CMOS image sensor, a shaping lens assembly, a parallel light tube, a telescope, a 2-D fine-motion unit, a 2-D fine-motion unit driver, a semiconductor laser, an encoder and a computer. A flat mirror is stuck on a surface of the 2-D fine-motion unit. Through the free-space optical-communication light-spot image processing detection system provided by the invention, a controllable hardware simulation environment is provided, a purpose of relatively accurate and relatively true results of a method for obtaining precision of conventional light-spot gray-scale image-noise removal methods and a method for obtaining precision of the to-be-detected light-spot gray-scale centroid is achieved, and the effect of the to-be-detected method can be visually reflected. The invention relates to the light-spot image processing field.
