Claim 8:
9. A non-transitory computer-readable storage medium that stores a projection adjustment program, the projection adjustment program, when executed by a processor, configured to cause a computer to perform processing related to adjustment of a projection operation of a projection apparatus in a projection system, the projection system comprising the projection apparatus and a processor, the projection apparatus configured to perform position measurement and projection on a target object, the processor configured to perform a setting processing for mask processing by the projection apparatus, the processing comprising:
performing position measurement by causing the projection apparatus of the projection system to project measurement light of invisible light onto the target object, receive reflected light of the measurement light reflected from the target object, and calculate position information of the target object based on the reflected light of the measurement light,
detecting an error region where a defect occurs in a measurement result of the position measurement, and
setting, for a target projection apparatus, a mask region for the mask processing of limiting a part of a projection range at a time of projecting the measurement light by using the measurement result of the error region,
wherein the processing is configured to detect a region where a measurement error occurs due to an obstacle in the projection range as the error region, and to set the mask region for the region.
