Appearance defect detection system and detection method for automobile engine cylinder body

The invention provides an automobile engine cylinder body appearance defect detection system and detection method, and belongs to the field of automobile engine cylinder body machining. The detection system comprises a conveying roller way, an appearance detection station, a cylinder hole inner wall detection station, a crankshaft hole inner wall detection station and a roller way conveying surface detection station. By adopting the appearance defect detection system and detection method for the automobile engine cylinder body, the engine cylinder body to be detected can be conveyed by utilizing the conveying roller way, so that the engine cylinder body respectively passes through the appearance detection station, the cylinder hole inner wall detection station, the crankshaft hole inner wall detection station and the roller way conveying surface detection station; the working surfaces and the hole series of the engine cylinder body are shot and detected through the 2D camera and the 3D camera which are corres
