A Low Cost Polarized Navigation Sensor Design

Abstract

In this paper, a low-cost bionic polarized light collection sensor is designed based on the sand ant navigation mechanism. The paper presents the basic theory and hardware implementation plan. At the same time, the algorithm and principle of polarization angle acquisition are introduced, which describe the calculation method in detail. At the end of the paper, the causes of the polarization angle error are analyzed and the error compensation method is given. The result of experiment shows that the sensor can collect the information of polarized light and the azimuth angle can be gotten effectively. Its error is about 2° and cost is low.
