Work assistance method and work assistance system

Abstract

The objective of this invention is to provide a method and system for performing accurate adjustments using a hypothetical measuring tool. The system scans the space containing the fluid nozzle 60, the object of the height adjustment operation, to obtain a spatial grid for the fluid nozzle 60. A hypothetical measuring tool 90 is generated, and a portion of it is designated as a contact detection point 91. The hypothetical measuring tool 90 is positioned at a predetermined location, causing the fluid nozzle 60 to descend. When contact is detected between the spatial grid for the fluid nozzle 60 and the hypothetical measuring tool 90, the height of the fluid nozzle 60 is adjusted by changing the color of the contact detection point 91 from blue to green. By using elements of the spatial grid as a medium, contact detection between the real object, the fluid nozzle 60, and the hypothetical object, the hypothetical measuring tool 90, can be performed.
