Image pick-up device and identity identification method thereof

Abstract

A camera device includes an image capturing module, a face detection module, a light detection and ranging (LIDAR) system, a storage module, and a microprocessor. The image capturing module continuously captures images of a determined filed. The face detection module detects the images to obtain a face to be tested, and records coordinates of the face in the image. The LIDAR system scans the face to be tested in the determined field according to the coordinates thereby to obtain three-dimensional information of the face to be tested. The storage module stores three-dimensional information of a determined face. The microprocessor compares the three-dimensional information of the face to be tested with the three-dimensional information of the determined face, and then outputs a recognition signal.

Description

technical field [0001] The invention relates to an imaging device and an identification method thereof. Background technique [0002] The laser scanning positioning (LIDAR, Light Detection And Ranging) system uses laser light to perform high-density scanning measurement on the object to be measured. According to the reflection characteristics of the light, when the laser light hits the object to be measured, it will be reflected back to the laser scanning and positioning system, so the data acquired by the reflected pulse can reflect the three-dimensional information of the object to be measured. [0003] In the field of apartment management or security monitoring, the traditional camera is not combined with a laser scanning positioning system. When detecting and identifying a person to be tested, it can only perform two-dimensional plane photos on the face of the person to be tested. Detection and recognition, therefore, when the light of the shooting scene changes, it wil...

Problems solved by technology

[0003] In the field of apartment management or security monitoring, the traditional camera is not combined with a laser scanning positioning system. When detecting and identifying a person to be tested, it can only perform two-dimensional plane photos on the face of the person to be tested. Detection and recognition, therefore, when the light of the shooting scene changes, it will have a greater impact on the recognition results, and in most cases, the camera cannot judge that the facial features of the person to be tested are derived from real people It's still a photo, so it's a security risk
