Problems solved by technology
The traditional inspection of the flatness of the mobile phone lining is visual inspection, and it is placed on a relatively flat workbench to observe whether the mobile phone lining has plane depressions, plane protrusions, boundary lifts, boundary depressions, corner lifts, and corners. This detection method completely depends on the proficiency of the quality inspector, and the detection efficiency is low and the accuracy is low; therefore, how to improve the efficiency and accuracy of mobile phone lining detection is a technical problem that needs to be solved

Description
technical field [0001] The present application relates to the technical field of visual detection, in particular to a detection method, device, electronic equipment and storage medium. Background technique [0002] At present, the manufacturing process of smart phones has been greatly developed, and the mobile phone lining is an important mobile phone component. The upper part of the mobile phone liner is used to place the LCD screen, and the lower part is used to fix the circuit board, camera and other mobile phone components. With the wide application of flexible display screens, the requirements for the flatness of the mobile phone lining on which the display screen is placed are becoming more and more stringent. The traditional inspection of the flatness of the mobile phone lining is visual inspection, and it is placed on a relatively flat workbench to observe whether the mobile phone lining has plane depressions, plane protrusions, boundary lifts, boundary depressions,...
