Projection control device, projection control method and projection control system

A projection control method of a projection control device, the projection control method comprising:

• connecting the projection control device to an image capturing device to communicate with each other, the image capturing device being configured to capture an image of a target object positioned around a projected object;
• deriving a projection position of a content image based on designation of a parameter related to the content image to be projected onto the projected object and an image of the projected object including the target object;
• generating a projection image including the content image disposed at the projection position;
• and
• transmitting a projection instruction of the projection image to a projection device,
• wherein the parameter related to the content image includes an angle or a direction and the number of pixels (n:
• an integer of 2 or more),
• wherein the method further comprises:
• performing a scan from a starting end to a terminal end of the image of the projected object so as to correspond to the angle or the direction of the image, and
• wherein the projection position is derived based on a detection position of an n-th pixel in the image of the target object during the scan.

A projection control system comprising:

• an image capturing device configured to capture an image of a target object positioned around a projected object;
• and
• a projection control device connected to communicate with the image capturing device,
• wherein the projection control device comprises:
• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
• deriving a projection position of a content image based on designation of a parameter related to the content image to be projected onto the projected object and an image of the projected object including the target object,
• generating a projection image including the content image disposed at the projection position, and
• generating a projection instruction of the projection image to be transmitted to a projection device,
• wherein the parameter related to the content image includes an angle or a direction and the number of pixels (n:
• an integer of 2 or more),
• wherein the operations further comprise:
• performing a scan from a starting end to a terminal end of the image of the projected object so as to correspond to the angle or the direction of the image, and
• wherein the projection position is derived based on a detection position of an n-th pixel in the image of the target object during the scan.
