Title:
THREE-DIMENSIONAL POINT CLOUD BASED THREE-DIMENSIONAL FACE RECOGNITION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/110007
Kind Code:
A1
Abstract:
Disclosed are a three-dimensional point cloud based three-dimensional face recognition device and method, the device comprising: a characteristic region detection unit for positioning a three-dimensional point cloud characteristic region; a mapping unit for conducting normalized mapping on a three-dimensional point cloud to a depth image space; a data calculation unit for calculating responses of three-dimensional face data at various dimensions and directions by using Gabor filters of the various dimensions and directions; a storage unit for a visual dictionary of the three-dimensional face data obtained by training; a mapping calculation unit for performing a histogram mapping between the visual dictionary and a Gabor response vector obtained by each pixel; a classification calculation unit for roughly classifying the three-dimensional face data; and a recognition calculation unit for recognizing the three-dimensional face data. The technical solution of the present invention has stronger descriptive capability for the detail texture of the three-dimensional data, and better quality adaption for inputting three-dimensional point cloud face data, thus having better prospects of application.
