摘要
提出了一种基于视角显示的特种车辆舱外观察系统。利用Zynq SoC处理器实现硬件尺度不变特征变换(SIFT)算法,对视角所对应的视频图像进行了实时拼接。针对人员视角起伏波动,提出了一种基于图像特征的快速电子稳像算法。实验结果表明,该系统对视角的解算误差不超过1°;电子稳像算法可以有效减小图像晃动;硬件SIFT算法可将图像特征拼接计算耗时加速至毫秒量级。
Abstract
A new observation system of special vehicle based on perspective display is proposed. The hardware scale-invariant feature transform (SIFT) algorithm is achieved based on the Zynq SoC processor, and the video images corresponding to perspective are spliced in real time. At the same time, a fast electronic image stabilization algorithm based on image features is proposed for the fluctuation of driver's perspective. The experimental results show that the perspective decoding error is less than 1°, the electronic image stabilization algorithm can reduce the image shaking effectively, and the hardware SIFT algorithm can speed up the processing time of image feature calculation to the order of millisecond.
