Assertion failed index_arg static_castunsigned int input_-pointssize file CBuildPCLx64pcl-181octreeincludepcloctreeimploctree_pointcloudhpp line 603

The error message indicates that an assertion failed in the PCL (Point Cloud Library) code. Specifically, the assertion failed at line 603 in the file "octree_pointcloud.hpp".

The assertion checks if the index argument is less than the size of the points in the input point cloud. This means that the index_arg variable is likely exceeding the range of valid indices for the point cloud.

To resolve this issue, you need to ensure that the index_arg variable is within the valid range of indices for the input point cloud
