UF_CAM_ask_leastsq_sphere函数详解

UF_CAM_ask_leastsq_sphere函数，通过给定的点集，计算最小二乘球体的球心和半径。

1、官方说明

2、使用实例

double sphere_center [ 3 ] = {0.0};//接收球心坐标 double sphere_radius = 0.0; //接收球半径 double point1[3] = {1,0,0}; //点击准备 double point2[3] = {0,1,0}; double point3[3] = {0,0,1}; double point4[3] = {1,1,1}; double* points[5]; //点集指针 points[0] = point1; points[1] = point2; points[2] = point3; points[3] = point4; if(int errCode = UF_CAM_ask_leastsq_sphere(points, 4, 0.0001, sphere_center, &sphere_radius) != 0){//异常情况下会无法计算，返回错误代码1 char message [ 133 ] = {0}; UF_get_fail_message(errCode,message); Keso::gLog.print("ERRCODE[%d]: %s",errCode,message); }else{//返回0，则计算成功，返回球心坐标以及球半径 Keso::gLog.print("sphere_center: %.3f, %.3f, %.3f",sphere_center[0],sphere_center[1],sphere_center[2]); Keso::gLog.print("sphere_radius: %.3f",sphere_radius); }
