Patent attributes
The invention relates to a graphical application system to apply a desired pattern by multiple tiles onto a target surface. The system comprises a graphical application device comprising a base structure with a trackable optical feature, at least one nozzle for expelling paint, a driving unit for positioning the nozzle and a local camera for a local referencing of the nozzle. A controller controls the driving unit and the expelling of the nozzle to achieve an application of the desired pattern on the target surface. The system also comprises an external referencing device located remote from the graphical application device, for a global referencing of the application device according to the trackable optical feature. The desired pattern is applied with a primary alignment of the application range by the global referencing and with a fine-alignment of the actual tile to a previously applied tile according to the local referencing.
