Video signal image processing method and device

Abstract

The invention provides a video signal image processing method and a device. The method comprises following steps of movement analysis including extracting characteristics of original image and calculating overall situation movement affine matrix among successive frames, wherein the overall situation movement affine matrix comprises movement parameters among the successive frames and the successive frames of the original image form the movement track of the original image; parameter smoothing including filtering the movement parameters among multiple successive frames, obtaining a movement parameter between the current frame and the previous frame after smoothing, and forming the movement track after the smoothing according to the movement parameter of the successive frames after the smoothing; and affine transformation including forming a new overall situation movement affine matrix and calculating the corresponding image of the current frame after the smoothing according to the movement parameter between the current frame and the previous frame after smoothing and the difference between the movement track of the original image and the movement track after smoothing. In this way, translation, rotation or shaking of overall movement of video images can be reduced or removed.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video signal image processing method and device. Background technique [0002] In recent years, civilian drones have developed rapidly in terms of technology and market. One of the biggest applications of civilian UAVs is aerial photography, especially for large scenes of outdoor shooting during flight. In the current UAV aerial photography application, the control of the aircraft is all manual, which puts high demands on the stability of the operation; at the same time, the operation of the aircraft control is separated from the operation of the shooting control, often requiring two people to control it separately, which increases the Complicated and unstable operation. Therefore, civilian drones usually use a stabilized platform to assist photography. [0003] At present, civilian drones usually use a three-axis electromechanical gimbal to form a photograp...

Problems solved by technology

For example, when a mobile phone or DV user uses a mobile phone or DV to take pictures, due to the unstable holding posture, it will cause the shake, rotation or swing of the captured video stream.
