Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to an image imaging shake compensation method, system and equipment. Background technique

[0002] With the progress of the times, video surveillance, as an important evidence for security protection systems and event tracing, has gradually become popular in all walks of life. When acquiring images, how to improve the accuracy of image imaging has also become a challenge.

[0003] Due to the consideration of driving safety and the development needs of autonomous driving, video surveillance is basically popularized in the vehicle field. However, due to the vertical vibration of the car during the movement, the vehicle video surveillance equipment (vehicle camera) when collecting images There will also be jitter, which will cause the position of the imaging object in the collected image to shift accordingly, resulting in the problems of blurred, low-definition, and p...
