Abstract

The invention provides a coating defect detection and marking system and method, which relate to an image acquisition and processing technology, belong to the technical field of nondestructive testing, and are used for detecting coating defects on the surface of an automobile body and marking the defects. The coating defect detection and marking system comprises a lighting device 1, a detection workshop bracket 2, a to-be-detected vehicle body 3, a track 4, a supporting base 5, a track moving device 6, a mechanical arm 7, a lighting source 8, a defect marking device 9, an image acquisition device 10 and a computer system 11. Defect detection can be carried out on the coating on the surface of the whole vehicle, coating defects are classified, defect marking is carried out with a solution with a specific color, and automatic and assembly line detection is carried out on the coating defects.

Description

technical field [0001] The invention relates to image acquisition and processing technology, belongs to the technical field of non-destructive testing, in particular to a coating defect detection and marking system. Background technique [0002] Non-destructive testing refers to the use of heat, sound and light caused by structural abnormalities or defects inside the material without damaging or affecting the performance of the tested object, and without damaging the internal tissue or external surface morphology of the tested object. Changes in reactions such as electricity, magnetism, etc., by means of physical or chemical methods, with the help of modern technology and equipment, the structure, nature, state and type, nature, quantity, shape, location, Methods of inspection and testing of dimensions, distribution and variations thereof. Optical imaging technology captures the light information reflected by the target to form the target image information in the sensor, wh...
