Abstract
A system in a vehicle includes a lidar system to transmit incident light and receive reflections from one or more objects as a point cloud of points. The system also includes processing circuitry to identify feature points among the points of the point cloud using principal component analysis. The feature points are planar points that form one or more surfaces or edge points. A set of edge points forms a linear surface.
