Abstract

The application discloses a display image processing method and device. The method includes: performing directional clustering on the straight lines in the display image to obtain two straight line sets containing the largest number of straight lines; calculating the blanking point corresponding to each straight line set in the two straight line sets; Data processing is carried out on the blanking points to obtain the perspective transformation matrix; the display image is corrected based on the perspective transformation matrix, and the corrected image of the display image on the orthographic projection surface is obtained. The present application can solve the technical problem in the related art that the image correction process cannot obtain the perspective transformation with high precision.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a display image processing method and device. Background technique [0002] Perspective transformation is a common image processing method, which is often used for image correction. In the research on cigarette display recognition of cigarette cabinet images, due to different models of digital cameras and cameras and different shooting angles, especially the camera angles of cigarette display images captured by mobile phone cameras are relatively random, and there is an inclination angle between the camera and the cigarette cabinet. Instead of facing directly vertically downward (orthographic projection), and the image of the cigarette area may also have a large rotation angle, this brings a huge challenge to the subsequent detection algorithm. In order to improve the performance of the cigarette detection algorithm, it is necessary to restore the perspect...
