Abstract

The invention provides an image output method and an output system of a most positive face based on a multi-camera array. The method comprises the following steps of: acquiring a plurality of face images of a current face captured by a multi-camera array at a time; analyzing a rotation angle of a current face in each of the face images, and selecting a face image from which the rotation angle is the smallest; judging whether the rotation angle of the current face in the newly acquired face image is smaller than the face image with the smallest rotation angle when the multi-camera array tracksthe current face; if yes, the newly acquired face image replaces the selected face image with the smallest rotation angle until the current face leaves the tracking range, and the final face image isoutput as the most positive face image of the current face. The invention selects the most positive face image acquired by the multi-camera array based on space and time, and outputs the most positiveface image with more accuracy, thereby providing more reliable data basis for subsequent face comparison.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a method and system for outputting the most frontal face image based on a multi-camera array. Background technique [0002] With the rapid development of my country's economy, my country's urban population is becoming increasingly dense, and the demand for how to strengthen urban traffic management, social security, and maintenance of stability is increasing. In addition, the increase in population mobility has increased the difficulty of manual investigation of criminals by public security personnel, and the efficiency and success rate are not ideal. It can be seen that modern cities need to set up checkpoints and video surveillance for floating people. [0003] The face capture system is designed to monitor people entering and exiting the security checkpoint. It is a new comprehensive application of video analysis face detection and tracking in the field of vi...
