AI Technical Summary

Technical Problem

In tunnel construction sites, the increasing distance between the projector and the projection surface due to excavation progress causes projection position shifts, making it difficult for supervisors to adjust the projector and markers manually, especially when there are no workers present to assist.

Method used

A projection system comprising a projector, camera, and control device that automatically determines projection parameters based on the captured image of the excavation work surface, allowing the system to adjust the projection position and content according to the excavation progress.

Benefits of technology

The system can automatically adjust the projection position and content to maintain visibility and relevance as the excavation surface moves, eliminating the need for manual intervention and ensuring workers receive appropriate information.

Abstract

We provide a projection system that can automatically determine the projection parameters of a projector. [Solution] The projection system 100 includes a projector that projects projection data M onto a projection target, a camera that captures a shooting area including the projection area of ​​the projection data projected onto the projection target, and a control device. The control device determines the projection area within the captured image of the shooting area and determines projection parameters for projecting the projection data M by the projector based on the size or shape of the projectable area.
