| Abstract: | A novel imaging bionic polarization navigation sensing device proto is designed by employing insect strategies for navigation. The skylight polarization distribution model is studied, and work principle of imaging bionic polarization navigation sensing device solves is analyzed. The problem of normal detection device polarized parameters needs upper PC aided, by using CMOS sensor and DSP, real time output navigation angle. Performance experiments are presented indoor and outdoor, and normalized intensity curves of the polarized component in three directions are obtained. Experimental result indicates that error of angle t of sensing device is --0.8°-0.3°（indoor） and --1.2°-1.4°（ outdoor）,it can output navigation angle with high precision and meet requirement of realtime navigation. |
