ELECTRONIC DEVICE AND METHOD FOR DETECTING SURFACE FLAW OF SAMPLE

摘要

A method for detecting surface flaws of a sample under test requires a detection device with a motorized horizontal rotating platform. The rotating platform is set to an initial position, and a camera unit of the detection device captures images of the sample. The method adjusts a position of an optical filter of the detection device according to the captured image until intensities of the light source projected on different positions of the sample are uniform. The horizontal rotation platform is further rotated to obtain images of the testing sample at different angles from the camera unit. The method converts colors of specified pixels of the obtained image into a specified color, to obtain processed images. Surface flaws of the processed images are detected, and a result is outputted to a display device.

主权项

1. An electronic device in communication with a detection device which provides a light source, comprising:
at least one processor; and a storage device storing one or more programs, which when executed by the at least one processor, cause the at least one processor to perform operations of: controlling a horizontal rotation platform of the detection device to locate to an initial position; controlling a camera unit of the detection device to capture an image of a testing sample placed on the detection device, and adjusting a position of an optical filter of the detection device according to the captured image until intensities of the light source projected on different positions of the testing sample are uniform; controlling the horizontal rotation platform to rotate to obtain images of the testing sample at different angles from the camera unit; obtaining processed images of the testing sample by converting colors of specified pixels of the obtained image into a specified color, wherein the specified pixels have luminance values within a luminance tolerance range; detecting surface flaws of the processed images; and generating a result indicating whether the testing sample has a surface flaw.
