为了实现偏振成像系统的小体积、低延时和快速目标检测,利用动态视觉传感器对动态场景灵敏度高、成像速度快的特点,提出了基于动态视觉传感器的偏振探测方法。从动态视觉传感器的对比度灵敏度出发,结合光学偏振原理,从理论上证明了基于动态视觉传感器偏振探测方法的可行性。设计并搭建了实验系统,由转台载着偏振片快速转动,由于视场内景物的反射光具有不同的偏振特性,经过旋转偏振片后发生明暗变化,动态视觉传感器快速捕捉变化并成像,系统采用嵌入式GPU(Graphics Processing Unit)控制并实时显示成像。实验结果表明:偏振系统对视场内的偏振度灵敏度为0.148,目标轮廓清晰,并具有良好的可视性。该系统弥补了传统偏振成像装置体积大、成像速度慢的不足,为基于偏振图像的目标检测等应用奠定了基础。
In order to realize a compact, low delay, and fast target detection polarization imaging system, this study takes advantage of the characteristics of a dynamic vision sensor with high sensitivity and imaging speed to study the polarization detection method based on the dynamic vision sensor and then designs and builds the experimental system. Based on the contrast sensitivity of the dynamic vision sensor and the principle of optical polarization, the feasibility of the polarization detection method based on the dynamic vision sensor is proved theoretically. The experimental system is designed and built. The rotating platform carries the polarizer to rotate it rapidly. Because the reflected light of the scene in the field of view has different polarization characteristics, the transmitted light changes in brightness after rotating the polarizer. The dynamic vision sensor quickly captures the changes and images. The system uses embedded graphics processing unit control and real-time display. The experimental results show that the sensitivity of the polarization degree in the field of view is 0.148, and the target contour is clear with good visibility. The proposed system overcomes the shortcomings of the traditional polarization imaging system, such as large size and low imaging rate,and lays the foundation for the application of target detection based on polarization images.
