Multi-User Shared Telescope Using Multi-Threaded High-Speed Active Camera

Abstract

This study proposes a new approach for multiple users to view the same area simultaneously using a dual-camera system that combines an ultra-high-speed active camera and a wide-angle camera. A tablet with an inclinometer installed is used to control each user’s line of sight. This allows users to manipulate the tablet in order to view the magnified area they wish to see while controlling an ultra-high-speed active camera with multi-threaded gaze control at hundreds of frames per second. This system is considered to be an unprecedented system because it allows multiple users to share information while looking at their own desired viewing points when watching something remotely, such as a surveillance system, factory inspection, or sports game. In the realtime experiment, we confirmed the accuracy of tablet operation when there were two users by comparing it with automatic control, and then confirmed the movement with five users.
