如何导出PointCloud以在Matlab中查看

Question

I use the OpenCV function

pointCloud = cv2.reprojectImageTo3D(filteredImg,disparityToDepthMap) / 420

to get an pointcloud of my stereo images.

I want to show it into matlab, I tried to load the data into matlab but i failed.

Answer 1

In order to save variables to be read later in Matlab, I recommend to store them as .mat documents executing the following line in python:

import scipy.io as spio

spio.savemat(r'C:\DirectoryNameofMatlabProject' , mdict={'namedata': namedata})

Once stored the .mat containing the desired data, in your case "pointCloud", you will need to open the .mat in Matlab. For this, just click in "Import Data".

Finally, in order to transform this data into a pointCloud object in Matlab, execute the following code:

ptCloud=pointCloud(namedata);

pcshow(namedata)

I hope you find it helpful.

Good luck!
