Sight tracking method and system, processing equipment and computer readable storage medium

Abstract

The invention discloses a sight tracking method and system, processing equipment and a computer readable storage medium, and the method comprises the steps: obtaining original images collected by a plurality of image collection devices, splicing the plurality of original images into a spliced image, and determining the responsible region of each image collection device in the spliced image; performing face preliminary positioning on the spliced image, and determining one or more original images corresponding to the face position subjected to the preliminary positioning according to the face position subjected to the preliminary positioning and the responsible area of each image acquisition device in the spliced image; and performing face secondary positioning on the determined one or more original images to obtain face pose information and a position relationship between pupils and human eyes, and calculating a fixation point coordinate of the human eyes according to the obtained face pose information and the position relationship between the pupils and the human eyes. The invention provides a method which is suitable for a large field of view and can track the sight lines of multiple persons at the same time, and the calculation complexity is effectively reduced while the calculation precision is improved.

Description

technical field [0001] The present disclosure relates to, but is not limited to, the technical field of intelligent display, and in particular, to a gaze tracking method, system, processing device, and computer-readable storage medium. Background technique [0002] With the continuous development of Virtual Reality (VR) / Augmented Reality (AR) technology, people's requirements for interaction methods are getting higher and higher, and non-invasive eye tracking systems have become the research in the field of interaction methods. hot spot. [0003] At present, in the process of calculating the user's line of sight, the following problems exist in the tracking of multiple people's gaze on a large-size display screen: [0004] 1. The medium and large size display screens have higher requirements on the field angle of view (FOV) of the camera; [0005] 2. In the case of a certain resolution, a higher field of view of the camera will affect the calculation accuracy; [0006] 3....

AI Technical Summary

Problems solved by technology

[0004] 1. Medium and large display screens have higher requirements on the field angle of view (FOV) of the camera;

[0005] 2. In the case of a certain resolution, a higher camera field of view will affect the calculation accuracy;

[0006] 3. Simultaneous multi-person gaze tracking will take up relatively high computing resources

[0007] In addition, the spatial gaze tracking systems currently on the market are usually only suitable for small-sized display screens and are usually used by a single person. They need to be calibrated before use. After the head moves and rotates, the accuracy will drop a lot
