Abstract

The invention provides a method, an apparatus, a storage medium and a terminal device for determining a line-of-sight area, wherein the method comprises the following steps of: acquiring a driver's face image; extracting feature points of a face region and an eye region of the driver from the face image; tracking an initial picture sequence of the face images to iteratively calculate feature points of the face region to obtain a head posture of the driver; estimating a classification result of the line-of-sight region observed by the driver based on a characteristic point of the eye region; and correcting the classification result of the line-of-sight area according to the head posture of the driver, and using the corrected line-of-sight area as the line-of-sight area of the driver. By adopting the invention, the line of sight area of the driver can be accurately obtained.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a method, device, storage medium and terminal equipment for determining a sight area. 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. In the process of determining the driver's sight area, the traditional solution is to use...
