Abstract

The invention relates to the technical field of image processing, and discloses a calibration point identification method, which comprises the steps of processing image data, and generating an external rectangle of a calibration object in an image, wherein the lower edge of the circumscribed rectangle extends downwards by a preset pixel coordinate length to generate a region of interest; traversing the region of interest to generate a marking region of a preset marker related to the calibration object; traversing the marking area to generate a middle line, and taking the pixel coordinate of the upper end point of the middle line as the pixel coordinate of the calibration point. The method has the advantages that manual interaction is reduced, and effective and automatic identification of the calibration points is achieved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a calibration point recognition technology in the field of image processing. Background technique [0002] Vision is an important means for humans to observe and understand the world, accounting for 70% of the information humans obtain from the external environment. Human beings use their eyes to obtain the light reflected by surrounding objects or emitted by themselves. The light forms an image on the retina and is transmitted to the brain through nerve fibers. The brain processes and understands the visual information and finally forms vision. Computer vision simulates the function of human vision, uses cameras to obtain images of the surrounding environment, and uses computers to process images. Computer vision can accomplish tasks that human vision is not capable of, such as accurate measurement of the size and distance of the object to be measured. Computer vision technolog...
