Research on Key Technology of Vehicle Electronic Image Stabilization

Abstract

The study of image stabilization algorithms plays an important role in achieving electronic image stabilization. This paper firstly introduces the basic concepts, principles and common typical algorithms of vehicle-borne electronic image stabilization technology. Then, based on the characteristics of vehicle-mounted image processing, this paper analyzes the influence of the instability of vehicle-mounted image sequences on the observation results of vehicle-borne systematic images, and introduces the vehicle-mounted electronic image stabilization technology. Besides, a method to achieve the stabilization of the inter-frame translation motion of vehicle-mounted dynamic image sequences using the gray projection matching algorithm is proposed. In the vehicle-mounted imaging system, the maximum gray value in the feature image is used to estimate the inter-frame motion of the image sequence, and a partition method is used to estimate the motion vector by selecting the gray-scale maximum point as the feature point in a certain scanning order, to ensure the validity of the algorithm. At the same time, based on characteristics of vehicle imaging, the necessity and possibility of detecting long-focus picture pick-up system and compensating the rotation movement are proposed, and the method of using the maximum gray value points as the image feature to estimate the inter-frame motion of the image sequence are presented.
