Abstract

A projection adjustment program which causes 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 including the plurality of projection devices. The process includes: causing a projection device to project measurement light onto the target object; causing an image capture device 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 projection device on a 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; generating projection position information indicating a connection relationship between projection ranges of the respective projection devices of the projection system; and displaying the generated projection position information on a display.

Claims (25)

1. 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, the plurality of projection devices configured to perform position measurement and projection on a target object in a projection system, the projection system comprising the plurality of projection devices, the process comprising:

causing a projection device of the projection system to project measurement light onto the target object;

causing an image capture 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 projection device on a 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 plurality of projection devices of the projection system and displaying the projection position information on a display,

wherein the projection position information comprises representative figures of the projection ranges of the plurality of projection devices.

2. The non-transitory computer-readable storage medium according to claim 1 ,

wherein, when the representative figures of the projection ranges of the plurality of projection devices have an overlap, the overlap is displayed in an emphasized manner.

3. A projection adjustment method of a projection adjustment device, the projection adjustment device configured to execute a process relating to adjustment of projection operations of a plurality of projection devices, the plurality of projection devices configured to perform position measurement and projection on a target object in a projection system, the projection system comprising the plurality of projection devices, the projection adjustment method comprising:

causing a projection device of the projection system to project measurement light onto the target object,

causing an image capture device of the projection system to receive reflection light, reflected from the target object, of the measurement light;

judging a connection relationship of a projection range of the projection device on a 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 the projection ranges of the respective plurality of projection devices of the projection system and displaying the generated projection position information on a display,

wherein the projection position information comprises representative figures of the projection ranges of the plurality of projection devices.

4. A projection system, comprising:

a plurality of projection devices configured to perform position measurement and projection on a target object; and

a projection adjustment device including a memory, the memory storing a projection adjustment program, the projection adjustment program, when executed by the projection adjustment device, causing the projection adjustment device to execute a process, the process relating to adjustment of projection operations of the plurality of projection devices, the process including:

causing a projection device of the projection system to project measurement light onto the target object;

causing an image capture 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 projection device on a 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 plurality of projection devices of the projection system and displaying the projection position information on a display,

wherein the projection position information comprises representative figures of the projection ranges of the plurality of projection devices.
