point_cloud.py #27

Closed annacesar closed 6 years ago

annacesar commented 6 years ago

I am trying to use you stereovision library to create point cloud, but I cannot get i to work. this the command that I have written: output = sv.point_cloud.PointCloud(points, colors) and this is the error that I get: module 'stereovision' has no attribute 'point_cloud'

Would you mind helping me in fixing this issue?

I am using openCV 3.3.1

erget commented 6 years ago

This is because __init__.py doesn't import the accompanying modules - you have to pull them in explicitly if you want to work with them directly, like so:

from stereovision.point_cloud import PointCloud
foo = PointCloud(points, colors)

Does that work for you?

annacesar commented 6 years ago

Thanks! Now the command has not given error, but I cannot find the 'foo' variable I have just created. How can I actually export it? What have you used to visualize the point cloud? Meshlab?

erget commented 6 years ago

Yes, Meshlab is my favourite for visualising point clouds. Sorry for the lack of clarity - foo is simply a placeholder for any variable, it's a meaningless name.

For exporting the point cloud, you can either use the command line utility images_to_pointcloud, which is described in greater detail here, or you can take a look at the sources and pull out the method that way.

I'm closing this since the original issue is solved.
