Three-Dimensional Face Recognition Device Based on Three Dimensional Point Cloud and Three-Dimensional Face Recognition Method Based on Three-Dimensional Point Cloud

摘要

The invention describes a three-dimensional face recognition device based on three-dimensional point cloud and a three-dimensional face recognition method based on three-dimensional point cloud. The device includes a feature region detection unit used for locating a feature region of the three-dimensional point cloud, a mapping unit used for mapping the three-dimensional point cloud to a depth image space in a normalizing mode, a statistics calculation unit used for conducting response calculating on three-dimensional face data in different scales and directions through Gabor filters having different scales and directions, a storage unit obtained by training used for storing a visual dictionary of the three-dimensional face data, a map calculation unit used for conducting histogram mapping on the visual dictionary and a Gabor response vector of each pixel, a classification calculation unit used for roughly classifying the three-dimensional face data, a recognition calculation unit used for recognizing the three-dimensional face data.
