A Python API for the SHOT descriptor

pyshot's Issues

Example for matching the descriptors?

Hi,

Is there an example or tutorial that shows how to match the extracted descriptors between two meshes?

Thanks.

The dimension of SHOT descriptor

Dear author,

Thanks for your work. I have encountered a problem when I use the library to compute SHOT descriptor. I notice in the comment it is mentioned that the dimension of the SHOT descriptor is equal to 16 * (n_bins + 1) * (double_volumes + 1). But when I set n_bins=11 and double_volumes=True. I always get a dimension with 128 rather than 352 as expected. Do you know why it would be the case.

Thanks in advance.

Best regards,
Dongliang

shot on point clouds

Hi,

Is it possible to use shot on point clouds?
I see here the list of faces is required.

Thanks

Installation PySHOT

I am running into some difficulties in the installation of pyshot. I followed the steps and installed eigen3, flann and LZ4 but I get this error message when I try to run "pip install ."

  cl : Command line warning D9002 : ignoring unknown option '-O3'
  shot_descriptor.cpp
  C:\Users\beyin\anaconda3\envs\lidar38_PySHOT\Lib\site-packages\pyshot\include\mesh.h(12): fatal error C1083: Cannot open include file: 'flann/flann.hpp': No such file or directory

  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.

Could you assist with that.

For "maxAngularSectors"

pyshot/src/shot_descriptor.cpp

Line 160 in 3837467

const int maxAngularSectors = m_doubleVolumes? 28: 12;

Hi,

In "src/shot_descriptor.cpp" line 160, the "maxAngularSectors" is set to 28/12 with/without "doubleVolumes".
I think it's probably 32/16 to indicate the number of volumes(i.e. sectors).

Thanks.
