Embodiment

[0092] First of all, the camera continuously collects image information at a working frame rate of more than 15 frames per second. We set the image information collected in the first frame as the first image, and use biometric recognition technology to detect the outer frame of the face on the first image. , the value of the face frame contained in the first image is obtained through the detection of the outer frame of the face, that is, the number of faces contained in the first image. Then an inquiry is initiated to the processor, if the processor is in a busy state at this time, then abandon the processing of the current image, if the processor is in an idle state at this time, then a comprehensive face scan is carried out to the first image, and the scanned image is obtained Describe the position information of each face in the first image, and extract the feature points of each face to obtain the feature point information.

[0093] Then we set the image collected in the n...

Abstract

The invention discloses a face detection method and a face detection device. The face detection method comprises the steps of: acquiring image information to obtain a first image; performing face outer frame identification on the first image to obtain a face frame numerical value of the first image; acquiring image information again to obtain a comparison image; performing face outer frame identification on the comparison image to obtain a face frame numerical value of the comparison image; comparing the face frame numerical value of the first image with the face frame numerical value of the comparison image; performing rapid face scanning on the comparison image when the numerical values are equal; and performing overall face scanning on the comparison image when the numerical values aredifferent. According to the face detection method and the face detection device, rapid face scanning is performed on the comparison image with the same face frame number as the first image, whether toprocess the current image information is decided according to whether a processor is in a busy state at present, large amounts of repeated and unnecessary image information are effectively eliminated, and the computing efficiency of a subsequent face identification module is improved.

Description

technical field [0001] The present application relates to the field of image recognition, in particular, to a face detection method and device thereof. Background technique [0002] With the increasing development of information science and technology, image recognition technology has become popular in people's lives. Among them, face detection and recognition technology has developed very fast and has been widely used in security, office and other fields. Specifically, in Before performing face recognition technology, face detection needs to be performed first. There is no good face detection technology in related technologies, which provides a large number of repetitive and unnecessary face images to the processor, which increases the number of subsequent face recognition templates. Therefore, there is an urgent need for a face detection method and its device to efficiently remove repetitive and unnecessary face images, so as to achieve the technical effect of reducing the...
