摘要

为了获得较高的天空偏振光导航精度

研究了天空光偏振模式的模型。设计了天空光偏振模式自动探测装置，用于获取大量的天空光偏振模式信息并构建天空光偏振模式模型。该装置克服了传统天空偏振光分布模式探测仪器操作繁琐，效率低的缺点，利用计算机控制角度旋转和相机拍照协同工作，能够简单快捷地实现一键采集一组天空偏振图像。测试显示，该装置能够准确地在预期位置完成偏振图像的采集工作。获得的图像偏振模式明显，对于光强度的探测精度优于0.237 5(3)灰度值(8 bits)，平均每个测量点耗时3.02 s，采集效率较传统偏振模式探测仪器大为提高，能够实现天空光偏振模式的有效探测。

Abstract

To obtain higher navigation accuracy of skylight polarization

the polarization model for skylight was researched. An automatic detecting system of skylight polarized pattern was designed to get a large number of images to build an accurate model of skylight. The system overcomes the complex operation and the low efficiency from traditional detecting systems. It integrates a camera and the control system of precision rotating platform in an acquisition system to acquire the polarized images rapidly and easily in a key gathering a group of images. The test indicates that the acquisition system can get all of images in the angle that we expect

and can obtain images with a clear polarized pattern. Furthermore

the detecting accuracy is better than 0.237 5(3) gray level (8 bits) for light intensity and average time-consuming is 3.02 s for every measuring point. These results demonstrate that the system has higher detecting efficiency and can execute an efficient detection of skylight polarized pattern.
