Abstract

The invention discloses a palm image correction method and device, equipment and a medium, and the method comprises the steps: obtaining a standard key point corresponding to a standard palm image, and obtaining a target correction point from the standard key point; obtaining a to-be-corrected palm image and corresponding correction key points, and obtaining to-be-corrected points from the correction key points; calculating a transmission transformation matrix according to the target correction point and the to-be-corrected point; and performing transmission transformation on the palm image tobe corrected according to the transmission transformation matrix to obtain a corrected palm image. The calculation process is simple. The correction process is simplified. The correction speed is increased. The process of conducting perspective correction on the palm image is simple. The calculated amount is small and speed is high.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a palm image correction method, device, equipment and storage medium. Background technique [0002] In the prior art, when performing perspective correction on the palm image, it is necessary to obtain camera environment parameters, such as pixel size, resolution, focal length and other parameters; and then calculate the corresponding vertical and horizontal deformation coefficients in the vertical and horizontal deformation directions respectively. Large volume, slow speed, and high requirements for images, especially for images that cannot provide regular edge information, it is impossible to achieve perspective transformation correction. [0003] Therefore, it is an urgent technical problem for those skilled in the art to find a method to solve the problems of complex processing, large amount of calculation, and slow speed in the existing palm image perspective co...
