The invention relates to the technical field of computers, in particular to a motion video image stabilization method and device, equipment and a storage medium. The method comprises the following steps: acquiring images of two adjacent frames in a motion video; respectively determining feature points of a previous frame of image and a next frame of image in the two adjacent frames of images; calculating an overall motion vector of the current two adjacent frames of images according to the feature points of the previous frame of image and the feature points of the next frame of image; calculating a jitter motion vector of the current two adjacent frames of images according to the overall motion vector of the current two adjacent frames of images and a picture content motion vector in the overall motion vector of the previous two adjacent frames of images; and performing motion compensation on the previous frame of image in the current adjacent two frames of images through Kalman filtering and the jitter motion vector of the current adjacent two frames of images to obtain a stable image of the next frame of image. According to the embodiment of the invention, the jitter of the moving video image is eliminated, and meanwhile, the motion characteristics of the picture content are kept.
Description
technical field [0001] This article relates to the field of computers, in particular to a method, device, equipment and storage medium for image stabilization of moving video images. Background technique [0002] With the development of image technology and computer technology, video has become an important and direct information dissemination medium. The generalization and diversification of human needs for video has given birth to a variety of camera platforms, and various camera devices such as handheld, vehicle, and airborne have entered people's lives. Sometimes, camera equipment has to be used on a vibrating platform. The vibrating environment will inevitably lead to mechanical vibration, which will cause video image jitter, and these jitters are often difficult to eliminate, especially under high-magnification lenses. These jitters seriously affect the observation and monitoring of videos. [0003] The concept of image stabilization is to eliminate various jitters of...
