Title
(EN) LIDAR POINT CLOUD COMPRESSION
(FR) COMPRESSION DE NUAGE DE POINTS LIDAR
Abstract
(EN)

Using LIDAR technology, terabytes of data are generated which form massive
point clouds. Such rich data is a
blessing for signal processing and analysis but also is a blight, making
computation, transmission, and storage prohibitive. The
disclosed subject matter includes a technique to convert a point cloud into a
form that is susceptible to wavelet transformation
permitting compression that is nearly lossless.
