Abstract

The invention discloses a rust spot detection system based on structured light. The rust spot detection system comprises a projector, a CCD camera and an image analyzing and processing unit. The structured light is projected to the surface of a to-be-detected object, the structured light is highly modulated by rust on the surface of the to-be-detected object and transmitted to the image analyzingand processing unit to be analyzed and calculated, then three-dimensional surface type data of the to-be-detected object can be obtained, and a three-dimensional graph is obtained.The present invention introduces automatic detection means in the rust spot detection link, the three-dimensional form of the rust spot can be accurately obtained, and the defects that existing manual observation is insufficient in observation precision, high in subjectivity, lack of data analysis link and the like are overcome.

Description

technical field [0001] The invention relates to the technical field of industrial surface detection, in particular to a rust spot detection system based on structured light. Background technique [0002] In the salt spray detection of industrial enterprises, there is a lack of objective and systematic means for the detection of rust spots. The existing rust spot detection system mainly relies on human observation, which has shortcomings such as insufficient observation accuracy, strong subjectivity, and lack of data analysis links. Contents of the invention [0003] The purpose of the present invention is to provide a rust spot detection system based on structured light, which solves the problems that the existing rust spot detection link mainly relies on human observation of rust spot area and rust spot thickness, insufficient observation accuracy, strong subjectivity, and lack of data analysis links. [0004] To achieve the above object, the present invention provides th...
