There are two algorithms for searching for reference marks in the laser module:

• ConC

This algorithm is suitable only for referenc

e marks consisting of

horizontal and/or vertical lines on a solid color background. It operates

by searching over a specified region of an image for lines.

• Ring Search

This algorithm is more suitable for products with busy backgrounds.

There is no need to have a completely solid color background over the

entire search area.

This algorithm is described later in this chapter.

The algorithm that will be used and the

parameters for that algorithm are

specified in a Vision Profile. A Vision Profile describes the search area and other

search parameters used for a specific vision mark on a product. Vision Profiles

are stored in the module VPD and are given user-assigned names.

In a product Setup, for each laser engraving operation element, a Vision Profile

can be specified. If specified, the Vision Profile will be loaded and the reference

mark will be sought and used to determine the offset to apply to the laser data.

Setting Up a Ring Search Vision Profile

A Vision Profile is setup from the laser module diagnostics panel.

1. Select Ap

plications | Utilities | Diagnostics

2. Select the Laser Engraving Module from the list

of system modules.
