Abstract

The present application provides a method and device for locating facial feature points. The method includes: obtaining a frame of target image currently to be processed from a video, where the target image contains a human face image; obtaining the horizontal face image in the previous frame image. Roll angle, the previous frame image is a frame image in front of the target image in the video and close to the target image; according to the roll angle, the target image is rotated; face feature points are located on the rotated target image to obtain the first A set of face feature points, the first set of face feature points includes a plurality of first face feature points; according to the roll angle, each first face feature point is mapped to the unrotated target image to obtain A plurality of second facial feature points in the target image respectively have a mapping relationship with the plurality of first facial feature points. The solution of the present application can improve the accuracy of face positioning for image frames in a video.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a method and device for locating facial feature points. Background technique [0002] With the development of technology in the field of computer vision, the technology of facial feature point positioning is becoming more and more perfect. Face landmark location has been applied in many fields. [0003] However, the current face detection and feature point location can only be applied to a single frame image. For video and other scenes that contain multiple frames of images, due to the large changes in face poses between multiple frames of images, the usual feature point location methods cannot Accurately locate the feature points of the face in each frame image. Contents of the invention [0004] In view of this, the purpose of the present application is to provide a method and device for locating facial feature points, so as to improve the accura...
