Mobile Printing device

A self-propelled printing apparatus to perform printing on an object to be printed, comprising:

• a moving unit that moves the self-propelled printing apparatus on the object to be printed;
• a printing unit that performs printing on the object to be printed on the basis of print processing data generated based on information of a position to which the self-propelled printing apparatus has been moved by the moving unit;
• and
• an optical sensor that detects light of a position information pattern projected by one or more projection means,
• wherein the position information is obtained by analyzing the light detection result of the optical sensor.

A self-propelled printing apparatus to perform printing on an object to be printed, comprising:

• a moving unit that moves the self-propelled printing apparatus on the object to be printed;
• and
• a printing unit that performs printing on the object to be printed on the basis of print processing data generated based on information of a position to which the self-propelled printing apparatus has been moved by the moving unit;
• wherein the position information is obtained using a surveying method.

A printing system to perform printing on an object to be printed, comprising:

• a moving unit that moves a self-propelled printing apparatus on the object to be printed;
• a position analysis unit that analyzes information of a position to which the self-propelled printing apparatus has been moved by the moving unit, wherein the position information is obtained by analyzing an image captured by an imaging element, and wherein the imaging element images a position information pattern projected by one or more projection means;
• a print processing data generation unit that generates print processing data on the basis of an analysis result of the position analysis unit;
• and
• a printing unit that performs printing on the object to be printed on the basis of the print processing data generated by the print processing data generation unit.

A printing method for performing printing on an object to be printed, comprising:

• a movement step of moving a self-propelled printing apparatus on the object to be printed;
• a position analysis step of analyzing information of a position to which the set-propelled printing apparatus has been moved in the movement step, wherein the position information is obtained by analyzing an image captured by an imaging element, and wherein the imaging element images a position information patter projected by one or more projection means;
• a print processing data generation step of generating print processing data on the basis of an analysis result in the position analysis step;
• and
• a printing step of performing printing on the object to be printed on the basis of the print processing data generated in the print processing data generation step.
