all features are achieved with spin image are zero

M rezaei
Hi
I want to use spin image and it's my code

pcl::SpinImageEstimation<pcl::PointXYZ, pcl::Normal, DescriptorType>
si(8,0.5,16);
si.setInputCloud(model_keypoints);
si.setInputNormals(model_keypoint_normals);
si.setRadiusSearch(descr_rad_);
si.setImageWidth(8);
si.compute(*model_descriptors);
si.setInputCloud(scene_keypoints);
si.setInputNormals(scene_keypoint_normals);
si.setRadiusSearch(descr_rad_);
si.setImageWidth(8);
si.compute(*scene_descriptors);

but all achieved features are zero.
Thanks

Here's an example showing how to use that class

https://github.com/PointCloudLibrary/pcl/blob/master/examples/features/example_spin_images.cpp

One thing that immediately stands out is that you don't set the search
method.

Cheers
