Title: POINT CLOUD PREPROCESSING AND RENDERING
Abstract:
The invention concerns a computer-implemented preprocessing method for dividing a point cloud in cells, whereby for each cell a set of levels of detail is created, each level of detail comprising a set of points and a minimal distance; a data structure for storing a preprocessed point cloud; a computer-implemented rendering method for creating a pixelated image based on a stored preprocessed point cloud and a view frustum; and a viewing method involving a computing system to select a view frustum with a user interface and to present a pixelated image of a point cloud on a screen.
