摘要
分析了一种基于CCD图像的太阳定位技术,将CCD调水平并由CCD摄像头实时地获取太阳的图像,通过USB接口与计算机相联,采用otsu算法对太阳图像进行数字图像处理并计算出太阳的方位角与俯仰角,获取太阳位置信息,达到对太阳定位的目的。根据计算得到的太阳位置,可调整太阳能接收装置,以最大限度地获取太阳能。
This paper presents a technique for sun location based on CCD imaging. Images of the sun are obtained by a horizontal CCD camera on real time and transmitted into a computer with a USB interface. The images are then digitally processed with otsu arithmetic, and the azimuth angle and pitching angle of the sun are worked out. The information acquired are used for determining the location of the sun which is important to the regulation of the solar energy receivers and collection of solar energy to the full extent.
