Abstract

The present invention provides a face quality evaluation method based on three dimensional point cloud data. The main content of the method comprises inputting the three dimensional face point cloud data; detecting a face specific area in the three dimensional face point cloud data; carrying out the data registration on the detected face specific area; carrying out the depth face data mapping on the registered three dimensional face point cloud data and carrying out the face depth data quality evaluation on the depth face data. According to the present invention, by utilizing the face specific area detection at a point cloud layer and utilizing the template data verification at a depth data layer, the three dimensional face data quality is evaluated, thereby being able to determine whether the acquired three dimensional data satisfies the face identification quality, effectively evaluating the face data quality layer by layer from the point cloud data space to the depth image space, and guaranteeing the quality of the data applied to a face identification algorithm.

Description

technical field [0001] The present invention relates to face data extraction and face data quality assessment in 3D point cloud data, especially refers to evaluating whether 3D face point cloud data obtained by acquisition equipment such as a 3D scanner can be used for effective face recognition. Background technique [0002] The face quality assessment method based on 3D point cloud data can be used to evaluate the quality of 3D face data obtained by 3D acquisition equipment. Or other uncontrollable conditions, it is not suitable to continue 3D face recognition, which saves the work of subsequent face recognition, simplifies the process, and saves time. The method can be used as a data preprocessing step for 3D face recognition to improve the efficiency of a 3D face recognition system. [0003] In the field of face recognition, due to the influence of expression, age, light, angle or other uncontrollable factors, the face recognition process becomes more difficult. The exi...
