Abstract

The present disclosure provides an ear key point detection method, device, storage medium and electronic equipment to solve the problem in the related art that it is difficult to detect ear key points when the ear is covered. The ear key point detection method includes : Identify the first human face area from the current frame image of the video stream; obtain the two-dimensional attributes of the ear key points in the first human face area on the screen plane through a two-dimensional detection algorithm; and, through the standard three-dimensional human head The grid model performs three-dimensional reconstruction on the first face area, and obtains the depth of the ear key points in the model in the screen space; determines the depth in the first face area by the depth and the two-dimensional attribute. The 3D position of the ear keypoint in the screen space.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an ear key point detection method, device, storage medium and electronic equipment. Background technique [0002] In recent years, with the popularization of applications such as short video and selfie beautification, ear special effects have also been widely used as part of face beautification. In related technologies, two-dimensional ear key point detection algorithms (such as convolutional neural network (CNN)) are usually used to determine the ear key points in the face image, i. The lower base point and the lower ear point, when the ear is visible, the position of the key point of the ear detected by this method is usually more accurate. However, the ear is different from other organs on the human face, such as the lips. The ear will be blocked when the face is profiled, and the image information of the blocked ear is missing. Therefore, it is difficul...
