摘　　要：基于Matlab 7.6/Simulink 7.1设计的实现太阳图像中光斑质心位置检测系统的仿真实验平台,可以实现从图像传感器采集太阳图像,并计算出光斑质心的图像坐标及光斑个数。Simulink主系统包括图像采集模块、图像增强子系统、图像处理子系统和光斑信息显示模块。实验结果表明,该仿真平台能够准确找出太阳图像中光斑质心的图像坐标,并给出光斑个数,该方法适用于基于图像传感器实现太阳自动跟踪的系统。The simulation experiment platform which is designed on the basis of Matlab7.6/Simulink7.1 to detect the spot centroid position in the sun image can capture the sun image by means of the image sensor and calculate the image coordinate of the sun spot centroid and spot quantity. The Simulink main system consists of image acquisition module, image enhancement subsystem, image processing subsystem and spot information display module. The experimental results show that the simulation platform can accurately find out the image coordinate of the spot centroid in the sun image and give the number of spots. This method is suitable for sun automatic tracking system based on image sensor.
