Projection adjustment program and projection adjustment method
View Patent ↗A non-transitory computer-readable storage medium stores a projection adjustment program which, when executed by a processor, causes a computer to execute a process relating to adjustment of projection operations of projection devices configured to perform position measurement and projection on a target object in a projection system including the projection devices. The process includes: causing a first projection device to project invisible measurement light onto the target object; causing a second projection device to receive reflection light reflected from the target object; judging a connection relationship of a projection range of the first projection device on the basis of the received reflection light; executing a process of the judging of the connection relationship on all processing target projection devices; and generating projection position information indicating a connection relationship between projection ranges of the respective projection devices and displaying the projection position information on a display unit.
