Research on a novel imaging bionic polarization navi-gation sensor for glimmer environment application
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 technolo-gy has better robustness, and it can obtain more polarization information. In this paper, an embedded imaging polari-zation 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 polariza-tion (AOP) image is calculated simultaneously with an acquisition and calculation speed of 10 frame per second. Sen-sor can obtain absolute rotation angle, and the AOP image can be displayed on liquid crystal display (LCD). It pro-vides an effective experimental platform for the research of imaging polarization mode navigation device based on embedded system.
