Detection system and detection method based on depth image information

Abstract

Embodiments of the invention disclose a detection system and a detection method based on depth image information. The system comprises a camera device used for acquiring a depth image of an object to be detected, an extraction device used for extracting a target area of the object to be detected based on the depth image and acquiring the feature point information of the target area, and a detection device used for detecting whether the object to be detected is a living body based on the target area and the feature point information. Through face identification based on the scheme provided by the embodiments of the invention, others can be prevented from pretending to be someone with a photo, a video or other nonliving object to pass adult face identification.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a detection system and method based on depth image information. Background technique [0002] Face recognition technology is widely used in identity verification systems. At present, face recognition based on images can more accurately identify faces from images, and by combining face databases for matching queries, the identity of faces can be determined. Due to the lack of determination of the source of the image, such systems cannot determine whether the detected object is the person. When the image input is a still picture containing a human face, or a continuous video, the system determines the identity of the face in the picture or video, not the real identity in reality, so there are potential risks such as impersonation and deception. The main problem of this type of system is the lack of a live body detection link, and it is impossible to determine whether th...

Problems solved by technology

Whether it is a passive or interactive approach, there is a problem that the user experience is not friendly enough

Passive flash may cause discomfort to the user's eyes, and under different lighting conditions, such as strong sunlight, the contrast of the flash effect may be inconspicuous or even invalid

The interactive method adds additional user operations, making the system more complicated to use

For some access control detection systems that come in and out frequently, a large number of repetitive operations will also reduce the friendliness of the user experience
