Embodiment Construction

[0048] The present invention provides a method and system for distinguishing a real human face from a picture human face. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] see figure 1 , which is a flow chart of the method for distinguishing a real human face from a picture human face in the present invention. As shown in the figure, the distinguishing method includes the following steps:

[0050] A. Use the camera calibration algorithm to calibrate the fixed first camera and the second camera, and calculate the projection matrix of the two cameras;

[0051] B. Obtain images collected by the first and second cameras that are synchronized in real time;

[0052] C. Perform face detection according ...

Abstract

The invention discloses a method and a system for distinguishing a real face and a picture face. Two cameras are adopted to acquire images. Partial depth information of the acquired images is reestablished via the two cameras so that an objective of distinguishing the picture face and the real face by using the cameras is realized. Meanwhile, a mode (i.e. the two cameras are adopted to acquire the images) based on binocular vision is adopted to realize matching of the face, extracting of characteristic points and reestablishing of three-dimensional coordinates of the characteristic points so that the method and the system for distinguishing the real face and the picture face are high is precision. Besides, a small amount of face characteristic points are used in the calculation process so that an algorithm has a relatively high speed as a whole.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for distinguishing real human faces from picture human faces. Background technique [0002] As the performance of various smart terminals (smart phones, tablet computers, and smart TVs, etc.) becomes more and more powerful, many intelligent algorithms based on machine vision or pattern recognition appear on various smart terminals, such as face detection and recognition technology , which utilizes analysis and comparison of face visual feature information for identity identification. This not only increases the intelligence of various terminals, but also provides a certain basis for human-computer interaction. [0003] However, the existing face detection and recognition algorithms are usually unable to distinguish whether the detected face is from a picture or a real face. This defect seriously affects the intelligence of the application. For exam...
