Abstract

A work information projection system () includes a projector (), a camera (), and a controller. The projector () projects an auxiliary image () onto a workplace. The camera () captures the workplace. During a work, the controller controls the projector () based on a position of the projector () to project the auxiliary image onto the workplace. During a calibration process of calibrating relative information, the camera () captures a calibration image projected by the projector () onto a calibration jig () through a reflector (). The controller performs the calibration process of calibrating the relative information based on the calibration image captured by the camera ().
