Embodiment approach

[0184] The first implementation of step 205: if the facial organ positioning information includes nose position information, right eye position information and the right end point position information of the mouth, then the nose position information is the x-axis coordinate value of the nose, and the right eye position information is the right eye position information. The x-axis coordinate value of the right endpoint of the mouth is the x-axis coordinate value of the right endpoint; if the x-axis coordinate value of the nose is greater than the x-axis coordinate value of the right eye, and the x-axis coordinate value of the nose is greater than the x-axis coordinate value of the right endpoint coordinate value, then it is determined that the detection result is that the facial image is a non-frontal facial image, wherein the face in the facial image is deflected to the right.

Abstract

The invention relates to a face detection method and device and a target detection method and device, and the method comprises the steps: obtaining a face image, determining face organ positioning information in the face image, and the face organ positioning information representing the position information of a plurality of face organs in the face image on the face image; determining a detectionresult according to the facial organ positioning information, the detection result representing that the facial image is a frontal facial image or the facial image is a non-frontal facial image; and when the detection result represents that the face image is the front face image, generating and displaying first prompt information. The facial organ positioning information is analyzed to determine whether the facial image is a frontal facial image or a non-frontal facial image. Therefore, the front face image can be accurately determined, the recognition method is accurate, and the front face image can be analyzed conveniently, and the first prompt information can be generated and displayed to prompt the user that the front face image is detected.

Description

technical field [0001] The present application relates to the field of video processing, in particular to a face detection method, a target detection method and a device. Background technique [0002] With the development of image and video technology, face detection has been applied to various fields. Facial detection technology can be used to obtain facial images and detect whether moving targets appear in various environments in real time. [0003] However, when the facial image is a non-frontal facial image, the moving target cannot be accurately determined; furthermore, how to detect non-frontal and frontal facial images is a problem that needs to be solved. Contents of the invention [0004] The present application provides a face detection method, a target detection method and a device to solve the problem of how to identify non-frontal and frontal facial images. [0005] The first aspect of the present application is to provide a face detection method, including:...
