Projection adjustment program and projection adjustment method

A non-transitory computer-readable storage medium that stores a projection adjustment program, the projection adjustment program, when executed by a processor, causing a computer to execute a process relating to adjustment of projection operations of a plurality of projection devices configured to perform position measurement and projection on a target object in a projection system comprising the plurality of projection devices, the process comprising:

• causing a first projection device of the projection system to project invisible measurement light onto the target object;
• causing a second projection device of the projection system to receive reflection light of the measurement light, the reflection light being 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 of the measurement 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 of the projection system and displaying the projection position information on a display unit.
