基于加速度传感器的红外图像稳像技术研究

摘要

This article analyzes how the image motion of infrared imaging equipment is generated in detail, and the infrared imaging equipment is fixed on an unstable platform. The method and algorithm of using micromachined accelerometer to get the image motion vector is proposed, and a measurement system of image motion vector which can be fixed on the infrared imaging equipment is developed. The experiments of image motion measurement and image stabilization are conducted, the results of which are compared to image stabilization through software. The effectiveness of theory and equipment are verified.%本文对安装于非固定平台上红外前视设备的像移产生的机理进行了详细分析,在此基础上提出了采用微机械加速度传感器获取像移矢量的方法及算法,并研制了可安装于红外前视设备上的像移矢量测量系统,利用三维摇摆台进行了像移测量和稳像试验,并与纯软件化稳像效果进行了比较,验证了本文提出的理论和方法的正确性,以及试验装置的有效性.
