Abstract

The invention is applicable to the field of intelligent terminal and image processing, and provides an image collection jitter removing method based on stereoscopic visual matching; the method comprises the following steps: using a FAST characteristic point to detect characteristic interest points of extracted forward and backward frames of images; using a scheme based on the ORB descriptor to match the FAST characteristic interest points of the forward and backward frames of images; using the normalization eight-point method based on the matched characteristic points to solve a transfer matrix F of the rotary motion of an image camera between the forward and backward frames; using the transfer matrix F to correct the deviation caused by the jitter, so as to obtain a corrected image. The provided method has the advantages of preventing jitter of multiple frames of images, and fast in calculating speed.

Description

technical field [0001] The invention belongs to the field of intelligent terminals and image processing, and in particular relates to a method and device for image acquisition shake elimination based on stereo vision matching. Background technique [0002] With the continuous improvement of living standards, image collection and mobile phone photography have become an indispensable part of people's lives. However, due to the influence of shooting technology and the movement of external objects, the images taken with bare hands may appear shaken and blurred. At this time, people often use external fixed balance devices, such as tripods, displacement detection sensing units, etc. to assist in shooting images. Through additional auxiliary tools, although the problem of anti-shake in image acquisition can be effectively solved, it also brings inconvenience to shooting, and huge tools must be carried with you. The post-image processing method makes it possible to solve the probl...
