Method, device, system and computer storage medium for line of sight detection

Abstract

Embodiments of the present invention provide a line of sight detection method, device, system and computer storage medium. The method includes: acquiring a human eye image of the object to be detected; determining a first line of sight direction when the object to be detected is gazing at a first preset position on a display screen according to the human eye image, determining that the object to be detected is gazing at the displaying a second line of sight direction at a second preset position on the screen, and determining a third line of sight direction in which the object to be detected looks at a third position on the display screen; according to the first line of sight direction, the second line of sight direction, the third viewing direction, the first preset position, and the second preset position to determine the third position. It can be seen that the embodiment of the present invention can locate the user's line of sight and determine the gaze position of the human eye according to the line of sight directions of the two preset positions. The process has nothing to do with the performance of the image acquisition device, and is universal and extensible.

Description

technical field [0001] The present invention relates to the field of image processing, and more particularly relates to a method, device, system and computer storage medium for line of sight detection. Background technique [0002] Face recognition has been widely used in various fields, and has achieved very impressive results. However, line-of-sight interaction has not been widely used. On the one hand, the accuracy of line-of-sight is not high enough. Another important aspect is that line-of-sight data is three-dimensional (3D) data, which needs to be combined with the scene when applied. The upper positioning of the gaze point needs to start from the perspective of combining the parameters of the camera, which makes it unable to adapt to a wide range of models and is not universal. Contents of the invention [0003] The present invention has been made in consideration of the above-mentioned problems. The invention provides a line-of-sight detection method, device, sy...
