基于视觉的太阳方位检测装置的研究

Solar Orientation Checking Equipment Research Based on Vision

研究一种基于视觉的太阳方位检测装置,该装置根据小孔成像原理将太阳投影为光斑图像,供图像传感器采集;采集的图像经2000系列DSP芯片处理,定位光斑的位置进而得到太阳光偏离的高度角和方位角,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的获取太阳能;通过求图像最大灰度值方法完成太阳定位,简化了定位算法;实验表明,该低速采集系统可实现太阳方位的检测;通过改进也可实现对各种点光源的检测,有一定的实用价值。

Solar orientation checking automatic tracking equipment based on vision was established. It projected sun for faeula based on theory about imaging by a little hole. This created condition for image sensor. DSP of. 2000 series processed the image data to fix on the position of faeula and gained warp angles of the azimuth angle and pitching angle. The information acquired were 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. It predigests the tracking arithmetic by finding the most grey value. The experiment indicated that it can realize the sun orientation checking through the low velocity collection system. It can be practical for checking the dot lamp--house by several ameliorations.
