1. A method comprising:
- obtaining an image about at least one object of interest and a three-dimensional (3D) point cloud about said object of interest;
aligning the 3D point cloud with the image;
segmenting the image into a plurality of superpixels preserving a graph structure and spatial neighbourhood of pixel data of the image;
associating the superpixels in the image with a subset of said 3D points, said subset of 3D points representing a planar patch in said object of interest;
extracting a plurality of 3D features for each patch; and
assigning at least one vector representing at least one 3D feature with a semantic label on the basis of at least one extracted 3D feature of the patch.

Abstract
A method comprising: obtaining an image about an at least one object of interest and a three-dimensional (3D) point cloud about said object of interest; aligning the 3D point cloud with the image; segmenting the image into a plurality of superpixels preserving a graph structure and spatial neighbourhood of pixel data of the image; associating the superpixels in the image with a subset of said 3D points, said subset of 3D points representing a planar patch in said object of interest; extracting a plurality of 3D features for each patch; and assigning at least one vector representing at least one 3D feature with a semantic label on the basis of at least one extracted 3D feature of the patch.
