ACTIVE SCENE THREE-DIMENSIONAL INFORMATION ACQUISITION METHOD BASED ON DIMENSIONALITY REDUCTION SPARSE REPRESENTATION

摘要

The invention provides an active scene three-dimensional information acquisition method on the basis of a dimensionality reduction sparse representation. The method jointly processes multiple one-dimensional active detection signals acquired synchronously, to realize three-dimensional positioning of objects or three-dimensional reconstruction of a scene structure within a detected scene. Through an active detection system equipped with one transmitter and multiple receivers, simultaneous three-dimensional positioning of multiple targets in the scene or three-dimensional reconstruction of a scene geometry is achieved.
