Projection system, projection adjustment program, and projection method

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.

A projection method, comprising:

• causing a projection apparatus to perform position measurement and projection on a target object;
• and
• causing a processor to perform a setting processing for mask processing of limiting a part of a projection range in which measurement light of invisible light is projected,
• wherein the projection apparatus performs the position measurement and projection on the target object by:
• projecting the measurement light onto the projection range partially limited by the mask processing;
• receiving reflected light of the measurement light;
• calculating position information of the target object positioned within the projection range based on the reflected light of the measurement light;
• determining a projection position of a content based on the calculated position information of the target object;
• and
• projecting the content onto the determined projection position,
• the processor is configured to cause the projection apparatus to project the measurement light to perform the position measurement, and to detect an error region where a defect occurs in a measurement result of the position measurement,
• the processor is configured to set, for a target projection apparatus, a mask region at a time of projecting the measurement light by using the measurement result of the error region, and
• the processor is configured to detect a region where a measurement error occurs due to an obstacle in the projection range as the error region, and set the mask region for the region.
