Hi,
let me answer your questions:
I tested your script and the scale of the resulting point cloud looks OK to me; I visually compared it to the corresponding OBJ file exported by Record3D, but I did not notice a scale discrepancy (at least not when manually aligning the two point clouds in CloudCompare after exporting the Open3D point cloud by o3d.io.write_point_cloud('/tmp/o3d_pc.ply', pcd)
).
May I ask how much bigger was the Record3D-exported point cloud compared to the point cloud generated by your script and which Record3D export option did you use?
Hi, when I said bigger I was not referring to the scale of the pointcloud, instead, I was talking about the number of points. For instance, the obj that the application exports has about 300k points, and the pc that my script generates has about 600k.
About that:
I currently do not plan to add the confidence image as a part of the USB stream, but if enough people will ask for this feature, I might add it.
I think it would be super useful and help a lot on getting better 3D reconstructions on streaming applications. If I can collaborate on any way to get that done, please let me know.
Apologies for the delay in my response and thanks for explaining what you meant.
The lower amount of points in the exported point clouds is the expected outcome — I deliberately lowered the amount of points in order to reduce the file size of the exported files (after all, the depth map is being upscaled, so no geometric detail is lost).
Regarding addition of the confidence map into the USB stream: I will try to implement it into the next Record3D update.
That makes sense! Which is the criteria that you applied to lower the amount of points?
The RGB images were downsampled to VGA resolution.
Hi,
I have a few questions about how to reconstruct the 3D point cloud:
In parallel, without taking into account all the unknowns that I presented earlier. I tried to do a first 3D point cloud reconstruction, with the following code:
The PC generated by this code is bigger than the one provided by the app. Am I doing something wrong?
