TemplateFinder3 - 63

TemplateFinder3 is the most important tool in Scorpion Vision Software.

Locating multiple objects in a scene is a very challenging tool. The tool is developed over more than ten years with continuous improvements. The tool design is based on a two step approach with a rotation and scale invariant template search for object candidates.  These candidates are validated by the unique PolygonMatch technology where the user can define the polygon edge model to ensure that the right object is selected. The tool is 100% multi-core meaning that the tool runs 4x faster on a quad-core computer. The system provides true sub-pixel accuracy.

Template matching is a technique in finding parts of an image which match a template image.

The versatility of TemplateFinder3 - TF3 - makes it suitable for a large number of applications:

  • Robot Vision - pick and place
  • 3D Stereo Vision
  • Object Counting
  • Object Location
  • Identification System
  • OCV - optical character verification
  • OCR - optical character reading

The Scorpion template matchers use a standard cross-correlation algorithm to match the template with the image.

 

 

 

 

 

Each match in TF3 is then optionally optimized using a polygon edge model with PolygonMatch technology.

Test and Sample Profiles

TemplateFinder3 is based on these features:

  • Image resampling and decimation
  • Multiple templates
  • Template masking
  • Template rotation
  • Template scaling
  • Template match sorting
  • Template constraints
    • Number of matches
    • Distance between matches
  • Template visualisation
  • PolygonMatch with sub-pixel accuracy

The TemplateFinder tool is a simple pattern matcher and are for some tasks faster and more suitable.
