摘　　要：设计一种基于COMS图像传感器的太阳自动跟踪控制器,上位机通过MCC实现VC++与Matlab联合编程,实时控制图像传感器获取太阳光斑图像。经Matlab计算,得到太阳光斑质心坐标与图像中心坐标的偏差,转化为水平和俯仰的步进电机需调整的步数,进而实时调整平面镜跟踪装置,使太阳光斑始终在图像中心位置。实验结果表明,该装置实现了太阳自动跟踪的目的,具有较高的跟踪精度。A solar automatic tracking controller based on CMOS image sensor is designed.Its host computer achieves a joint programming of VC＋＋ and Matlab based on MCC,and obtains the sun spot image by real-timely controlling the image sensor.The deviation between sun′s mass center coordinates and image center coordinates is calculated by Matlab.The calculation is converted into the steps of the level and pitch stepper motor to be adjusted.Real-time adjustment of plane mirror tracking device is achieved,so that sun spot has always being the center of the image.The experimental results show that the device automatically tracks the sun,and has high tracking accuracy.
