Abstract

The embodiment of the present invention discloses an information detection method. The method includes: obtaining surface parameter information of the object to be measured; the surface parameter information includes parameter information of feature points on the surface of the object to be measured; based on the parameter information of the feature points, acquiring and The pixel value corresponding to the parameter information of the feature point, and generate a first image based on the pixel value; recognize the object in the first image to obtain a recognition result, and determine the surface defect information of the object to be tested based on the recognition result. The embodiment of the invention also discloses an information detection device and a computer storage medium.

Description

technical field [0001] The invention relates to the field of electronics and information technology, in particular to an information detection method, equipment and computer storage medium. Background technique [0002] After the production of the product is completed, the product needs to be inspected to determine whether the surface of the product is defective. In related technologies, a method of capturing two-dimensional images by a camera or a magnetic flux leakage detection method is used to detect defects on the surface of a product. However, when the camera is used to take pictures of the product, it will be affected by the light and the oil on the product, so that the captured image cannot accurately reflect the surface defect information of the product; and the magnetic flux leakage detection method is only applicable to ferromagnetic material products. detection, and it is easy to miss the area with a large range of surface defects. Therefore, in the related art...
