Equipment for printing an image on to a large surface, comprises means to mark surface as grid and tool which determines it's position and orientation on grid then paints according to stored data

摘要

The tool has a handle (301), an optical unit (303) able to read the tool position on a grid projected on to the large surface and an orientation unit (305). These data define the tool position and attitude and are used with a localization section (309a) in a memory (309) to find stored printing instructions which are applied to printing means (307). All the tool operations are controlled by a microprocessor (304) and bus (310)
