C++读取txt点云数据代码

你好，以下是读取txt点云数据的代码示例：

#include <stdio.h>
#include <stdlib.h>

#define MAX_POINTS 10000

typedef struct {
    float x, y, z;
} Point;

int main() {
    FILE *fp;
    char filename[] = "point_cloud.txt";
    Point points[MAX_POINTS];
    int num_points = ;

    fp = fopen(filename, "r");
    if (fp == NULL) {
        printf("Error opening file %s\n", filename);
        exit(1);
    }

    while (fscanf(fp, "%f %f %f", &points[num_points].x, &points[num_points].y, &points[num_points].z) == 3) {
        num_points++;
        if (num_points >= MAX_POINTS) {
            printf("Maximum number of points exceeded\n");
            break;
        }
    }

    fclose(fp);

    printf("Read %d points from file %s\n", num_points, filename);

    return ;
}

希望能对你有所帮助。
