AI Technical Summary

Technical Problem

The prior art is difficult to effectively process images projected on screens of any shape, especially when multiple users share the same real environment, resulting in disturbance of the user's VR experience.

Method used

Through the image processing device and method, information of each user is obtained, the user's field of view overlapping areas are determined, and the objects are classified into background and foreground. Generate background images shared by all users and foreground images unique to each user, and output individual images in time-division mode through the output protocol, ensuring that each user sees only images for their own motion parallax effects.

Benefits of technology

It realizes that when multiple users share the same real environment, each user can have a perfect VR experience, avoiding image interference between users, and improving the projection mapping effect and user experience.

Abstract

An image processing device for processing a projection image presented to a plurality of people at the same time is provided. The image processing device: acquires information about each user; specifies an overlapping area where the fields of view of two or more users overlap based on the information about each user; classifies objects included in the overlapping area into a first object group or a second object group; generates a common image composed of the first object group common to all users; generates an individual image composed of the second object group different for each user; and further determines an output protocol for displaying each individual image.
