Research on a novel imaging bionic polarization navigation sensor for glimmer environment application

Abstract:

Polarization navigation system is a hotspot in the field of bionic navigation. Compared with point source polarized light navigation sensor, the polarization information acquisition method based on image sensor and imaging technology has better robustness, and it can obtain more polarization information. In this paper, an embedded imaging polarization sensor for glimmer environment application is designed and developed. The multi-channel video processing technology of TMS320DM642 is used to capture the polarization information of charge coupled device (CCD) camera with three channels. The images are processed by digital signal processer (DSP) in real time, and the angle of polarization (AOP) image is calculated simultaneously with an acquisition and calculation speed of 10 frame per second. Sensor can obtain absolute rotation angle, and the AOP image can be displayed on liquid crystal display (LCD). It provides an effective experimental platform for the research of imaging polarization mode navigation device based on embedded system.
