Product detection system and method based on spectrum confocal displacement sensor

The invention provides a product detection system and method based on a spectrum confocal displacement sensor, and the method comprises the steps: starting an LED light source, and irradiating a to-be-detected product through the LED light source according to a preset mode; acquiring image data of the to-be-detected product by using a camera; converting coordinate values of coordinate points in the image data from the camera coordinate system to coordinate values in a world coordinate system to obtain coordinate data of the to-be-detected product; obtaining a first track of the to-be-detected product detected by the spectrum confocal displacement sensor according to the coordinate data; controlling the spectrum confocal displacement sensor to move according to the first track so as to collect surface data of the to-be-detected product; and analyzing the surface data, and outputting a detection result. Through the scheme of the invention, the related data of the product to be detected can be accurately obtaine
