Ruler E
Overview
The result from measuring one cross-section of the object – the
measurement data
– is
collected into a
profile
. These profiles are sent to a computer connected to the camera
through an Ethernet network. The computer runs a custom application that takes care of
the profiles from the camera. This application can for example analyze the data to find
defects in the objects and control a lever that pushes faulty objects to the side.
Before the Ruler can be put into production you must write such an application. It is devel-
oped in for example Microsoft Visual Studio, using one of the APIs delivered with the
software for the camera.
Figure 1.2 – Profiles are sent from the Ruler to a PC, where they are analyzed by a custom
application.
Note that the output from the camera is not actual images of the object, but a set of
height, intensity or scatter values – one value for each point along the cross section of the
object. If desired, these measurements can be visualized as a profile plot showing the
shape of the cross section, or – by combining several profiles – as a complete 3D image of
the object.
