Abstract

The invention relates to the technical field of image processing, and provides an image imaging jitter compensation method, system and device, and the method comprises the steps: installing a gravitysensor at a parallel position of a camera assembly, and obtaining the jitter acceleration data of the camera assembly in real time through the gravity sensor; adopting an SOC chip as a main control module, and utilizing the operation function of the SOC chip to perform logic operation on collected moving images and jitter acceleration data to obtain correction coordinates of a target object. According to the invention, the simple and low-cost gravity sensor is additionally arranged, so the shaking displacement of the target object is effectively detected; the SOC chip with highly integrated circuits and comprehensive functions is adopted to perform data operation, and direct output from moving images and jitter acceleration data to correction coordinates is realized, so the effective compensation of jitter displacement of a target object is realized on the basis of ultra-low manufacturing cost, and the accuracy of image imaging is greatly improved.

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...
