Programming Basics 7-5
The Vision System
An essential component of the programming and production process of fluid dispensing is
the Vision System. The Vision System is capable of automatically locating features on the
workpiece so that patterns can be placed accurately. The Vision System hardware consists of
a camera, light source, Cognex
Ò
Vision Processor and video board. The software portion
includes Fluidmove for Windows NT (FmNT) which controls all programming and
dispensing functions and uses the Asymtek Vision for Windows (AVW) library in
conjunction with Cognex software to perform fiducial location and edge detection functions.
The video image you see in the Teach Window is supplied by the Vision System. Figure 7 -2
is a block diagram showing the interaction between the components of the Vision System.
