偏振成像及其优化技术研究
Study of the Polarization Imaging and Optimization Technology
摘要
Abstract
The amount of exposure received by the imaging device and the sensitivity of the device all had crucial impacts to the image quality and the polarization information in the polarization imaging technology. We analyzed the influence to the sky polarization information when changed the amount of exposure and the sensitivity of the imaging device respectively. In the sunny weather day,device is easy to overexposure,so the approach to be first taken was to reduced the amount of exposure.Experiments show that when reduced the amount of exposure by 5 times,the accurate of polarization information can be increased 48%. Secondly,the device sensitivity was changed by controlling the ISO degree. Experiments show that when each ISO level is lower in one grade,the similarity can be increased 5%. And the similarity can be achieved the maximum when the ISO is 100,the measurement accuracy can be up to about 70%.关键词
