Automatic detection system for skylight polarized pattern
摘要
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(3δ) 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.关键词
