Vehicle-mounted video electronic image stabilization method, system, electronic image stabilizer and storage medium

Abstract

The present invention provides an in-vehicle video electronic image stabilization method, system, electronic image stabilizer, and storage medium. The method comprises: obtaining an input video frame image, preprocessing the image, and thereby obtaining a valid video frame to detect characteristic corner point information; obtaining characteristic corner point pairs between two video frames based on the characteristic corner point information, and optimizing the obtained pairs; further performing an affine transformation on the characteristic corner point pairs, calculating offset parameters of an affine matrix based on the characteristic corner point pairs, performing judgment, performing differentiation on the offset parameters based on the judgment result, recording an empty frame image, performing motion filtering and reconstruction filtering, and performing an inverse affine transformation on the current video frame image; performing parameter compensation based on the recorded empty frame image, and finally outputting the video. The present invention solves the jitter problem of in-vehicle video images, and can also perfectly achieve video stabilization for partial images of empty frames in the video according to the real-time vehicle speed.
