基于双光楔的像移补偿方法研究
The study of image motion compensation method based on a double wedge
摘要
车载扫描凝视系统在扫描成像时由于转台转动而引起的像移必然造成图像质量下降, 进而导致虚警率升高, 要消除像移必须进行像移补偿。基于像移产生原因以及双光楔对光束的导向模型, 推解出因转台旋转而需补偿的光楔的初始位置及旋转速度, 来补偿曝光阶段引起的像移。提出了基于双光楔的像移补偿的新方法。
Abstract
The image motion caused by the turntable’s rotation when vehicle scanning gaze system works leads to the increase of false alarm rate. To eliminate the image motion, image motion compensation must be conducted. Based on the cause of image motion and the model of beam steering, this paper calculates the double wedge’s initial position and rotational speed through the double wedge image motion compensation analysis to compensate the image motion in the exposure phase caused by the turntable’s rotation. This paper proposes a new method on image motion compensation based on a double wedge.
