可计算任意多边形的质心和边缘凸点的坐标，该多边形由若干边缘坐标点确定。 给定的边缘坐标点越多，计算结果越精确。,The function applied to calculate the coordinate of barycenter and boundary embossses of a polygon,which is determined by boundary points. The points,the preciser of the result.

该函数实现的是激光光斑中心检测。首先对光斑进行预处理，然后利用灰度重心法来计算得到光斑的中心坐标,最后利用MATLAB的绘图功能描绘出光斑中心位置的变化情况。-This function is implemented in the laser spot detection. First spot pretreatment, and then use the barycenter method to calculate the coordinates of the center of the sp

阈值重心法实现光带中心线提取，可用于结构光扫描的模型建立，处理二值化图像等。(Threshold barycenter method is used to extract the center line of optical band. It can be used to model structured light scanning and process binary images.)
