Embodiment Construction

[0055] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0056] see figure 1 , an embodiment of the present invention provides a method for detecting a face angle. This embodiment can be applied in the field of human-computer interaction: for example, when the user browses e-books, videos, online stores, etc., the interest of the user is obtained. This embodiment can also be applied to a driver's attention detection scene while driving in vehicles such as automobiles, ships, and airplanes. This embodiment is not limited to the application scenarios exemplified above, and this embodiment can be applied as long as head posture is involved. In addition, in this e...

Abstract

The invention provides a method, an apparatus, a storage medium and a terminal device for detecting a face angle, wherein, the method comprises the following steps of: acquiring a face image of a detection object; obtaining pixel information of pixel points of the face and positions of each pixel point by using a two-dimensional geometric circle to locate the face of the face image; determining aposition of each pixel point in the three-dimensional geometric model according to a position of each pixel point in the two-dimensional geometric model and a geometric mapping relationship between the two-dimensional geometric model and the three-dimensional geometric model; determining a face angle of the detection object based on pixel information of each pixel point at a position of the two-dimensional geometry and a position of the three-dimensional geometry model. The invention improves the accuracy of detecting the face angle.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, storage medium and terminal equipment for detecting face angles. Background technique [0002] In recent years, with the popularity of vehicles, traffic safety has increasingly become one of the safety issues that everyone pays attention to. How to avoid traffic accidents, in addition to complying with objective requirements such as traffic order, human subjective factors are also very important. Among the man-made subjective factors, the more important ones are the driver's attention and driving posture. Therefore, how to avoid causing car accidents because the driver's inattention just seems particularly critical. [0003] During the driving process, the change of the driver's attention can be studied by detecting the change of the driver's sight area. The traditional solution is to use the method of deep learning to obtain the detection frame of ...
