Embodiment Construction

[0086] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0087] First introduce the technical terms:

[0088] TOF (Time of Flight, time-of-flight ranging method): A technical means to obtain distance by calculating the flight time of light.

[0089] SVM (Support Vector Machine, Support Vector Machine): It is a common discriminant method. In the field of machine learning, it is a supervised learning model, usually used for pattern recognition, classification and regression analysis.

[0090] RGB-IR: RGB (Red Green Blue, red, green, blue)...

Abstract

The embodiment of the invention provides a face anti-counterfeiting detection method, a face anti-counterfeiting detection device and a multi-view camera. The face anti-counterfeiting detection methodcomprises the following steps: acquiring a depth image, an infrared image and an RGB image by using a TOF camera and an RGB camera; analyzing the RGB image through a preset face detection algorithm,and determining an RGB face region of a face in the RGB image and position information of the RGB face region; determining a depth face area of the face in the depth image and an infrared face area ofthe face in the infrared image according to the position information of the RGB face area; and when the depth face area, the infrared face area and the RGB face area respectively meet corresponding preset rules, judging that the face passes the detection. According to the face anti-counterfeiting detection method provided by the embodiment of the invention, face living body detection can be completed without the need for a user to cooperatively execute corresponding actions, the detection time can be saved, and the user experience is good.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a face anti-counterfeiting detection method, device and multi-camera. Background technique [0002] With the development of technologies such as e-commerce, face recognition has become the most potential means of biometric authentication. While face recognition technology has greatly improved the convenience of people's lives, its security issues have gradually attracted people's attention. In order to prevent criminals from cracking face recognition through photos, live face anti-counterfeiting detection technology has also become a research hotspot. [0003] In the relevant face detection technology, the detection device will issue random action commands, such as blinking, shaking the head, or even read a string of random numbers, etc., and then use the camera to detect whether the user's response meets expectations. However, it needs the cooperation of the...
