给我matlab读取几组txt点云坐标并用不同颜色显示的代码

以下是 Matlab 读取几组 txt 点云坐标并用不同颜色显示的代码：

clear all; close all; clc;

% 读取 txt 文件
file1 = 'pointcloud1.txt';
file2 = 'pointcloud2.txt';
file3 = 'pointcloud3.txt';

data1 = load(file1);
data2 = load(file2);
data3 = load(file3);

% 绘制点云
figure;
scatter3(data1(:,1), data1(:,2), data1(:,3), 10, 'r', 'filled');
hold on;
scatter3(data2(:,1), data2(:,2), data2(:,3), 10, 'g', 'filled');
scatter3(data3(:,1), data3(:,2), data3(:,3), 10, 'b', 'filled');
xlabel('X');
ylabel('Y');
zlabel('Z');
legend('Point Cloud 1', 'Point Cloud 2', 'Point Cloud 3');
grid on;

希望能对你有所帮助！
