Abstract

The invention discloses a detecting system for a cylinder inner wall based on structured light. The detecting system comprises a computer, a CCD camera, a structured light controller, a reflecting mirror and a mounting sleeve. The detecting system is characterized in that the structured light controller, a reflecting mirror center and the CCD camera are all arranged on the central axis of the mounting sleeve; the distance between the structured light controller and the CCD camera is a specific value; structured light irradiates the surface of the cylinder inner wall to generate diffuse reflection; reflected light spots and an object in a current view field are jointly formed on the CCD camera; the light spots are imaged as one high-brightness line segment, and other backgrounds are imagedas data with lower brightness; an optical signal can be converted into an electrical signal; the high-brightness line segment formed through light spot mapping is acquired by a computer, the mass center of the high-brightness line segment is calculated, and further the to-be-detected distance is calculated. The system has main advantages that detection precision of the surface of the cylinder inner wall is significantly improved; meanwhile, the detecting system can be applied to detection of inner walls of deep hole parts; a method is simple and convenient.

Description

technical field [0001] The invention relates to the field of three-dimensional detection of real objects, in particular to a cylinder inner wall detection system based on structured light. Background technique [0002] At present, the three-dimensional detection technology for physical objects can be divided into two categories: contact measurement and non-contact measurement according to whether the measurement sensor is in contact with the surface of the object. [0003] In touch measurement, the three-coordinate measuring machine is the most representative. The basic operation of the three-coordinate measuring machine is to measure the "point". The probe on the three-coordinate measuring machine touches the surface of the object to be measured and moves along the surface. Movement; during the movement, the probe moves up and down with the surface fluctuations of the measured object, and continuously records the position of each point; then calculates the distance and posi...
