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

Abstract

The embodiment of the invention provides a method, a device and a system of line-of-sight detection and a computer storage medium. The method includes: acquiring human eye images of a to-be-detected object; according to the human eye images, determining a first line-of-sight direction at the time when the to-be-detected object gazes at a first preset position on a display screen, a second line-of-sight direction at the time when the to-be-detected object gazes at a second preset position on the display screen and a third line-of-sight direction at the same when the to-be-detected object gazesat a third position on the display screen; and determining the third position according to the first line-of-sight direction, the second line-of-sight direction, the third line-of-sight direction, thefirst preset position and the second preset position. Therefore, the embodiment of the invention can realize line-of-sight positioning on a user according to the line-of-sight directions of the two preset positions, and determine the gazing position of human eyes. A process thereof is independent of performance of an image collection device, and has universality and extensibility.

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...
