matlab生成三维点云

在MATLAB中生成三维点云的示例代码如下所示：

% 读取点云数据
load('pointCloudData.mat');

% 取出点云簇标记列
cluster_labels = pointCloudData(:, 7);

% 将点云簇标记列转化为离散的整数值
unique_labels = unique(cluster_labels);
label_int = zeros(size(cluster_labels));
for i = 1:length(unique_labels)
    label_int(cluster_labels == unique_labels(i)) = i;
end

% 将不同簇的点赋予不同的颜色
colors = lines(length(unique_labels));

% 绘制点云
figure;
scatter3(pointCloudData(:, 1), pointCloudData(:, 2), pointCloudData(:, 3), ...
    10, colors(label_int, :), 'filled');
axis equal;
xlabel('X');
ylabel('Y');
zlabel('Z');
title('3D Point Cloud');```

这段代码首先加载包含点云数据的MAT文件，然后将点云簇标记列转化为离散的整数值。接下来，通过为不同的簇分配不同的颜色，使用scatter3函数在三维空间中绘制点云。最后，设置坐标轴标签和标题，显示生成的三维点云图。<span class="em">1</span>
