Graphical application system

摘要

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 (1) comprising a base structure (11) with a trackable optical feature (15), at least one nozzle (17) for expelling paint, a driving unit (12) for positioning the nozzle (1) and a local camera (14) for a local referencing of the nozzle (17) with respect to a visual feature. A controller (4) controls the driving unit (12) and the expelling of the nozzle (17) to achieve an application of the desired pattern on the target surface (3). The system also comprises an external referencing device (2) located remote from the graphical application device (1), for a global referencing of the application device (1) according to the trackable optical feature. The desired pattern (5) is applied with a primary alignment of the application range (13) by the global referencing and with a fine-alignment of the actual tile (9) to a previously applied tile (8) according to the local referencing.
