Problems solved by technology
[0003] However, in the prior art, video image stabilization methods through algorithms often include the motion states of all objects in the collected images during motion estimation.
Among them, when the collected image contains the motion state of the moving object in the application scene, it will interfere with the calculation result of the video image stabilization, affect the external disturbance isolation effect, and reduce the video quality

The embodiment of the invention provides a video image stabilization method and device and a computer readable storage medium. The video image stabilization method comprises the following steps: selecting a first area in a first image; determining one or more first feature points according to the selected first area, performing feature point matching on the first image and a second image to obtainat least one feature point matching pair between the first image and the second image, each feature point matching pair comprising a first feature point of the first image and a second feature pointof the second image; carrying out motion parameter estimation according to the obtained feature point matching pairs; and performing motion compensation on the first image according to the estimated motion parameters to obtain a compensated first stable image.
Description
technical field [0001] The present application relates to the field of image processing, and in particular, to a video image stabilization method, a video image stabilization device, and a computer-readable storage medium. Background technique [0002] Video stabilization methods are mainly used to isolate external disturbances to imaging systems, targeting systems or positioning systems. Specifically, video image stabilization methods can be roughly divided into two categories: image stabilization methods using sensors and image stabilization methods performed through algorithms. Among them, the image stabilization method by algorithm usually includes several steps of motion estimation, motion smoothing and motion compensation. Through these processing steps, the motion offset of the camera carrier can be known, so that the above motion offset can be removed during video output, so as to display a more stable video image frame sequence and improve the video output quality....
