The embodiment of the invention provides a face detection method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a depth map; inputting the depth mapinto a face detection model to obtain a face position of the depth map output by the face detection model; determining a detection result of the face position based on the face size corresponding tothe face position and the standard face size range of the depth map, wherein the face detection model is obtained by training based on the sample depth map and the face position of the sample depth map. The embodiment of the invention provides a face detection method and device, electronic equipment and a storage medium. Face detection is performed on the depth map through the face detection modelwithout depending on a two-dimensional image so that accurate detection of the face under the scene of poor illumination condition can be realized, the limitation of the type of the depth camera canbe avoided, the accuracy of the face position can be judged by fully utilizing the depth information, and the risk of false detection of face detection can be reduced.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a face detection method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of face recognition technology, people are more and more concerned about the accuracy and security of face recognition. The common two-dimensional face recognition technology (usually using RGB images for face recognition) is increasingly difficult to improve the accuracy of face recognition due to the limitation of the amount of information in the image itself. In addition, the authentication system using two-dimensional face recognition technology is vulnerable to attacks by malicious attackers using props such as user's face photos. Compared with two-dimensional face recognition technology, three-dimensional face recognition technology has more data dimensions and a larger amount of information, which can break through the ac...
