Problems solved by technology

However, due to product problems such as the unevenness of the material and structure of the product to be tested, and the detection environment such as insufficient detection illumination, the monitoring effect of optical detection is limited to a certain extent.
For example, when optically inspecting a notebook computer, due to the uneven material of the notebook itself, changes in the light angle, and changes in the placement position, many irregular noises will be left in the captured pictures, which seriously interfere with the content to be tested extraction of

Abstract

The invention discloses an image processing method. The image processing method comprises the steps of performing optical detection on a to-be-detected image to obtain image data; obtaining a featuredistribution histogram of a to-be-detected region in the to-be-detected image based on the image data; classifying the image data based on the feature distribution histogram; and performing denoisingprocessing on the image data based on the classification. According to the image processing method provided by the invention, denoising processing is performed on the image data based on the feature distribution histogram, so that interference noise points in the image are removed, and the accuracy of optical detection is improved.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to an image processing method and electronic equipment. Background technique [0002] At present, optical inspection has become an important inspection method for inspecting the appearance of products in various production and manufacturing. However, due to product problems such as unevenness in the material and structure of the product to be tested, and detection environmental problems such as insufficient detection illumination, the monitoring effect of optical detection is limited to a certain extent. For example, when optically inspecting a notebook computer, due to the uneven material of the notebook itself, changes in the lighting angle, and changes in the placement position, many irregular noises will be left in the captured pictures, which seriously interfere with the content to be tested extraction. Contents of the invention [0003] The invention provides an image proce...
