GRAPHICAL APPLICATION SYSTEM

摘要

The invention concerns a graphical application system, with a surface spattering device, that comprises at least one nozzle means for an expelling of a spattering material onto a target surface, a nozzle control mechanism to control characteristics of the expelling of the nozzle means and a spattering material supply. The system further comprises a spatial referencing unit to reference the spattering device in space for determining a position and orientation of the spattering device and a computation means to automatically control the expelling by the nozzle control mechanism according to information gained by the spatial referencing unit and according to predefined desired spattering data as a digital image or a CAD-model comprising a digital representation of a desired pattern to be spattered onto the target surface, in such a way that the target surface is spattered according to the desired spattering data. Also a communication means for establishing a communication link from the spatial referencing unit to the computation means to supply the position and orientation to the computation means is comprised. Therein the spatial referencing unit is located remote from the spattering device and comprises at least two optical 2D cameras arranged with a stereobasis inbetween the cameras, for determining the position and orientation by digital image processing of images taken by the cameras 31.
