A projection display system and method based on human eye tracking

Abstract

The invention discloses a projection display system and method based on human eye tracking, which relates to the technical field of projection display, and aims to adjust projection image output on ascreen in real time by tracking eye point positions of audiences so as to enable the audiences to be always in an optimal viewing angle. The system comprises a projection unit, a screen, a position tracking unit, an induction glasses, a matching processing unit and a control unit, the induction glasses is connected with the position tracking unit, the position tracking unit and the matching processing unit are respectively connected with the control unit, and the control unit is connected with the projection unit; the position tracking unit is used for sensing the positions of eye points of audiences wearing the sensing glasses in real time; the matching processing unit is used for collecting optimal projection angle data of the projection units corresponding to the multiple eye point positions, and generating and storing matching data; and the control unit is used for correspondingly calling the corresponding optimal projection angle data from the matching data according to the received audience eye point position data so as to adjust the projection output angle of the projection unit.

Description

technical field [0001] The present invention relates to the technical field of projection display, in particular to a projection display system and method based on human eye tracking. Background technique [0002] The existing movie viewing system generally adopts the scheme that the audience sits in a fixed position in front of the screen to watch movies. By installing fixed seats or dynamic seats at the fixed positions, the purpose of fixed or dynamic movie viewing can be realized. During the installation and commissioning of the video system, whether it is a fixed seat or a dynamic seat, it is set according to the perspective of the normal sitting posture of the human body, so that the audience can obtain the best viewing effect in the standard sitting posture, but in actual use During the process, it was found that for fixed-seat viewers, after sitting for a long time, they will change their sitting posture from time to time, which will cause the position of the viewing ...

[0002] The existing movie viewing system generally adopts the scheme that the audience sits in a fixed position in front of the screen to watch movies. By installing fixed seats or dynamic seats at the fixed positions, the purpose of fixed or dynamic movie viewing can be realized. During the installation and commissioning of the video system, whether it is a fixed seat or a dynamic seat, it is set according to the perspective of the normal sitting posture of the human body, so that the audience can obtain the best viewing effect in the standard sitting posture, but in actual use During the process, it was found that for fixed-seat viewers, after sitting for a long time, they will change their sitting posture from time to time, which will cause the position of the viewing angle to change accordingly, especially for movies or games that require a higher viewing angle. Significantly reduce the viewing effect. For the dynamic seat with the change of the motion posture of the seat itself, the audience needs to constantly adjust the body posture to ensure the best viewing angle, which also greatly reduces the viewing angle for the audience.
