Abstract

The present invention provides a line-of-sight estimation method, device, system and storage medium. The line-of-sight estimation method includes: acquiring a human eye image to be processed; locating human eye key points of the human eye image; and based on the human eye image The key points determine the gaze direction of the human eye in the human eye image. The line-of-sight estimation method, device, system, and storage medium according to the embodiments of the present invention use key points of the human eye to estimate the line of sight of the human eye in the human eye image, which can simulate the complex mapping relationship between input features and line-of-sight, and effectively solve the problem of shallow model or line of sight. The problem of inaccurate estimation of the linear model, thereby improving the accuracy of the line of sight estimation, and the processing speed is fast.

Description

technical field [0001] The present invention relates to the technical field of computer vision, and more particularly to a line of sight estimation method, device, system and storage medium. Background technique [0002] In computer vision, line of sight estimation refers to locating the eye area of ​​the face and estimating the line of sight direction of the human eye based on the iris position based on the input face image. Traditional line-of-sight estimation methods need the help of external equipment, such as infrared light sources to make the spot more obvious, and are easily affected by illumination, occlusion and posture; or rely on the positioning accuracy of the human eye area, and it is difficult to accurately describe the characteristics of the human eye relationship with sight. [0003] Therefore, a new line-of-sight estimation scheme needs to be provided. Contents of the invention [0004] The present invention proposes a line of sight estimation scheme, wh...
