Requires: NI Vision Development Module
Use the Contour Analysis VIs to extract contours from an image, fit contours with an equation, learn and compute contour data, and to classify contour data.
| Palette Object | Description |
|---|---|
| IMAQ Extract Contour |
Extracts a single, best contour from an image. If the input image is calibrated, the contour will be learned with calibration. |
| IMAQ Fit Contour |
Fits a contour with an equation. The fit will occur in corrected space if the contour is calibrated. |
| IMAQ Overlay Contour |
Overlays a contour on an image. |
| IMAQ Get Contour Info |
Returns all the information describing a contour. |
| IMAQ Compute Curvature |
Computes the curvature profile along the contour. |
| IMAQ Classify Curvature |
Classifies the contour located in the given image. |
| IMAQ Compute Contour Distances |
Compares a target contour with a template contour, and calculates the distance between the contours. |
| IMAQ Classify Contour Distances |
Classifies the distance between a image containing a contour and a template image containing a contour. |
| IMAQ Setup Learn Contour Pattern |
Optimizes and fine-tunes advanced parameters used during the learning phase. Run this VI before the IMAQ Learn Contour Pattern VI. |
| IMAQ Learn Contour Pattern |
Creates a description of the template image for which you want to search during the contour matching phase. |
| IMAQ Setup Match Contour Pattern |
Sets parameters that are used during the matching process. |
| IMAQ Advanced Setup Match Contour Pattern |
Optimizes and fine-tunes advanced parameters used during the contour matching phase. |
