Abstract

The invention is applicable to the technical field of digital image processing, and provides a light bar center extraction method, terminal equipment and a storage medium, and the method comprises the steps: obtaining an original image comprising a light bar; extracting the maximum gray value of each row or each column in the original image, and determining an initial coordinate of a light bar center according to the maximum gray value; calculating the offset of the light bar center initial coordinate in the original image according to a preset model; and calculating the actual coordinates of the light bar center in the original image according to the offset and the initial coordinates of the light bar center. According to the light bar center extraction method, the terminal equipment and the storage medium provided by the embodiment of the invention, the detection time can be shortened while the detection precision is improved, and the problem that the detection efficiency and the detection precision cannot be considered at the same time when the light bar center coordinates are extracted at present is solved.

Description

technical field [0001] The application belongs to the technical field of digital image processing, and in particular relates to a method for extracting the center of a light bar, a terminal device and a storage medium. Background technique [0002] When using a light sensor, such as a line structured light sensor, for measurement and detection, it is necessary to accurately extract the center coordinates of the light bar corresponding to the light sensor. However, in practical applications, the image quality of the light strip will change with the surface shape, material and environment of the measured object, which brings difficulties to the extraction of the center coordinates of the light strip. At present, in extracting the coordinates of the center of the light strip, there is a problem that the detection efficiency and detection accuracy cannot be balanced, which hinders the real-time accurate measurement of digital images to a certain extent.
