Lens contamination detection method, device and equipment

Abstract

The present invention relates to a lens dirt detection method, device and equipment, the method comprising: acquiring a lens image captured by the lens to be detected; combining the center point coordinates of the lens image, dividing the image into two partitions and a total area, combining The gray value of different areas is used for partition detection, and the comprehensive detection is carried out according to the gray value of the total detection area. By performing corresponding dirt detection on both the partition and the total detection area including the partition, the detection data of the partition and the detection data of the total area are summarized as the overall detection result of the lens to be detected. Detect whether there is dirt on the lens through image partitions, realize automatic detection of lens dirt, avoid detection errors caused by manual identification, and detect more comprehensively, which can improve the reliability of lens dirt detection.

Description

technical field [0001] The invention relates to the technical field of lens detection, in particular to a method, device and equipment for detecting lens dirt. Background technique [0002] With the development of science and technology and the continuous progress of society, mobile phones are becoming more and more common in people's daily work and life, and mobile phones with lenses can also meet users' needs for taking pictures and taking photos. The lens of a mobile phone is composed of a lens, which is an optical device used to form an image on a film. In the process of lens production and lens assembly, there will be defects such as dust and dirt on the lens due to direct or indirect contact. [0003] The traditional lens dirt detection method mainly relies on manual identification under a high-power microscope, which is a heavy workload and subjective consciousness, which affects the reliability of product inspection. Contents of the invention [0004] Based on th...
