Positioning method and device, storage medium

Abstract

The invention discloses a positioning method, device and storage medium. The method obtains the grayscale image of the object to be measured, and determines the target region to be measured and the first grayscale change region adjacent to the target region to be measured according to the grayscale value of each pixel on the grayscale image; area and the first gray scale change area to determine the target gray scale value, and use the target gray scale value to determine the actual edge pixels of the target area to be measured in the first gray scale change area, and then determine the center position of the target area to be measured and the reference The relative distance of the position is used to obtain the position information of the target area to be measured. On the one hand, the boundary of the target area to be measured can be determined more accurately, and then the position of the target area to be measured can be determined more accurately; on the other hand, according to the embodiment of the present invention, automatic measurement can be realized without manual naked eye measurement, and efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a positioning method and device, and a storage medium. Background technique [0002] During the production process of the product, it is necessary to measure the position or size of the product to control the quality of the product. Exemplarily, in the display panel industry, it is necessary to know the location of the target area in the display panel more accurately, for example, the location of the packaging area, the location of pixel evaporation, and the like. However, in the prior art, the position of the target area is usually determined by manual measurement after the image of the object to be measured is acquired, but the manual measurement error is large, and the position of the target area cannot be accurately determined. [0003] Therefore, how to accurately determine the position of the target area is a technical problem urgently needed to be solved by thos...
