Screw pattern matching pattern
The pattern matching pattern provides the template against which pattern matching searches are compared. This should be the ideal part/feature for the application under the ideal circumstances (illumination, placement, etc.)
Pattern matching tools
VisionGauge®’s powerful pattern matching tools are adapted to solve a wide range of applications to identify and accurately locate objects in images and features on objects. These robust pattern matching tools are adapted for arbitrary objects & features in any orientation, can handle partial occlusion and hold up to partial deformation, and deal well with variations in illumination and noise.
Edge Breaks – Rounded edges
VisionGauge OnLine can handle locating the edge break of rounded edges completely automatically with high-accuracy.
sharp edge – edge breaks
VisionGauge OnLine’s Edge Breaks tool is capable of automatically locating edge breaks on sharp edges.
Automated edge break measurements – 2
VisionGauge OnLine’s Edge Breaks tools filters out spurious noise for a best-fit line and has user-selectable parameters – for example to allow a certain variation in distance (Delta) from the calculated line before selecting the edge break.
Automated edge break measurements – 1
VisionGauge OnLine’s Automated Edge Breaks tool includes parameters to filter out noise and a tolerance for allowed distance from the calculated line. There are no limitations to the line angle at which lines meet. Results are completely operator-independent.
VisionGauge® Counting and Sizing
You can also specify an ROI so only a target area of the image is considered. The image can be analyzed in various color channels: Luminance, Hue, Saturation, and the different Gamma colors. Selecting objects in the field of view using these channels greatly enhances your ability to produce highly-accurate results.
Part Groups Interface in the VisionGauge OnLine software
Part Groups help group inspections in different fields-of-view, allowing you to build an overall inspection ‘map’ of a part that does not fit entirely in the camera’s field-of-view at once. You can revisit inspection areas and track the individual Pass/Fail results of each area, as well as combining Pass/Fail results into a single overall result.
