MATLAB 对Ply文件进行 读取、显示、连线操作

1、函数：pcread

showPointCloud([x_s(:),y_s(:),z_s(:)+4]);
title('Sphere with the default color map');
xlabel('X');
ylabel('Y');
zlabel('Z');
hold on,
showPointCloud([x_t(:),y_t(:),z_t(:)]);

for k = 1:size(matchedPointsValid,1)
x = [matchedPointsValid(k,7) matchedPointsValid(k,10)];
y = [matchedPointsValid(k,8) matchedPointsValid(k,11)];
z = [matchedPointsValid(k,9)+4  matchedPointsValid(k,12)];
plot3(x,y,z,'r.-');
hold on,
end
saveas(hf,matched_points_file);  % 保存图片

画矩形 ：

选取矩形框内数据：

figure, imshow('pout.tif');

h = imrect;

position = wait(h);
