When inspecting the side of the hand-held device for defects, the existing patrol-type component appearance defect inspection system needs to shoot the side of the hand-held device. Although the intensity of the illumination light source can help to obtain the appearance of defects, it is easy to cause the corners and borders of the handheld device to appear almost smooth. As a result, when the side image of the handheld device is detected to have defects, the system cannot distinguish from the image Find out which side has the defect, so that the traditional inspection system for the appearance defect of the mobile component can only judge whether there is a defect on the side of the hand-held device, but cannot determine the specific location of the defect. Trouble in multiple inspections, rework operations, and waste of time in inspection operations

The invention relates to an appearance flaw detection system and method. The method includes: acquiring a testing sample's current image shot by a camera shooting unit of a detection device, with the current image including a side image and a projected image of the testing sample; conducting flaw detection operation on the side image of the testing sample, and determining the rotation angle of the testing sample according to the projected image of the testing sample; when a flaw is detected in the side image of the testing sample, acquiring a corresponding side image template according to the rotation angle of the testing sample; comparing the side image of the testing sample with the acquired side image template, and determining the side block where the flaw appears in the testing sample. With the system and the method provided by the invention, the appearance flaw detection accuracy of the testing sample can be improved.
Description
technical field [0001] The present invention relates to a detection system and method, in particular to an appearance defect detection system and method. Background technique [0002] In order to improve the robustness of the shell of the handheld device, most of the shells of the handheld devices are cut and manufactured in one piece, and the corners of the shell are also rounded for safety considerations. When inspecting the side of the hand-held device for defects, the existing patrol-type component appearance defect inspection system needs to shoot the side of the hand-held device. Although the intensity of the illumination light source can help to obtain the appearance of defects, it is easy to cause the corners and borders of the handheld device to appear almost smooth. As a result, when the side image of the handheld device is detected to have defects, the system cannot distinguish from the image Find out which side has the defect, so that the traditional inspection ...
