Point Cloud Based Surface Construction

摘要

A method and apparatus for filtering point cloud data obtained using a plurality of sensors generates data representative of a surface and for use with a specific type of sensor. The filtering allows certain machines and sensor types to be used to acquire point cloud data and different sensor types to be used during surface construction and modification. The method can be utilized with various types of machine controls and surface construction methods.

1. A method for modifying a surface, the method comprising:
generating a first set of surface data by moving a first plurality of sensors over the surface, the first plurality of sensors comprising a first type of height sensor; generating a point cloud based on the first set of surface data; generating a sensor specific surface representation by filtering the point cloud based on a second type of height sensor, the second type of height sensor different from the first type of height sensor; generating a second set of surface data by moving a second plurality of sensors over the surface, the second plurality of sensors comprising the second type of height sensor; and modifying the surface based on comparing the second set of surface data to the sensor specific surface representation.
