电子稳像技术概述

Overview of the electronic image stabilization technology

随着电视摄像系统在各领域中的广泛应用，对图像信息的稳定性要求也在不断提高。而图像的不稳定主要是由摄像机载体的运动导致的，因此运动载体上的电视摄像系统需安装稳像系统 电子稳像是新一代的稳像方法，它利用数字信号处理等技术实现实时、高精度地稳定动态图像。本文介绍了电子稳像技术的原理、实现方法、主要算法以及评定其优劣的方法。

Along with wide applications of TV camera , the requirement for image stabilization becomes more and more rigid. As the camera carrier' s movement causes unstability of images, the camera on the mobile carrier needs an image stabilizer. The electronic image stabilizing technology is a new generation of image stabilizing method, which makes use of the digital signal processing to realize the real - time and high - precision mobile image stabilization. The paper not only introduces the principles and the basic methods of realizing electronic image stabilization, but also gives its main algorithms and the evaluation of algorithms.
