以下是一个用C语言计算两个点云之间垂直度的代码示例:
#include <stdio.h>
#include <math.h>
#define N 100
typedef struct {
double x, y, z;
} Point;
double dot_product(Point a, Point b) {
return a.x * b.x + a.y * b.y + a.z * b.z;
}
double norm(Point a) {
return sqrt(a.x * a.x + a.y * a.y + a.z * a.z);
}
double angle(Point a, Point b) {
return acos(dot_product(a, b) / (norm(a) * norm(b)));
}
double verticality(Point *cloud1, int n1, Point *cloud2, int n2) {
double sum = .;
int count = ;
for (int i = ; i < n1; i++) {
for (int j = ; j < n2; j++) {
Point a = cloud1[i];
Point b = cloud2[j];
double ang = angle(a, b);
if (ang > M_PI / 2.) {
ang = M_PI - ang;
}
sum += ang;
count++;
}
}
return sum / count;
}
int main() {
Point cloud1[N] = {{., ., .}, {1., ., .}, {., 1., .}};
Point cloud2[N] = {{., ., .}, {., 1., .}, {., ., 1.}};
int n1 = 3, n2 = 3;
double vert = verticality(cloud1, n1, cloud2, n2);
printf("Verticality: %lf\n", vert);
return ;
}
