Adhesive Path Inspection - Contour

Operator Function

This operator uses contour-based methods to measure whether the adhesive strip is broken, its width, height, and other parameters. It selects the input adhesive strip point cloud and outputs in global variables whether the adhesive strip meets requirements, width, and height information.

Parameter Introduction

Region	2D Window/2D Circular Window/2D Polygon Window/Box/Cylinder Box/Rotated Box/Point Set (Binding Only)	Box	Manually select appropriate ROI region Can bind to select existing ROI regions
Step Length		1.000	Set the length in Y direction when segmenting regions
Broken Adhesive Point Limit		100	When the number of points in the divided adhesive point cloud region is less than this value, it is judged as broken adhesive
Reference Height		0.000	Input reference height value
Detection Height		0.1	Set point cloud above reference height by this value as adhesive strip

Height Measurement	Maximum Height/Minimum Height	Maximum Height	Maximum Height: Set height measurement mode to maximum height Minimum Height: Set height measurement mode to minimum height
Judgment Mode	Any/Continuous	Continuous	Any: When any number of regions judged as broken exceeds the set outlier count, judge as NG Continuous: When several consecutive regions judged as broken exceed the set outlier count, judge as NG
Outlier Count		1	Set to judge as NG when number of outlier values exceeds this value
Minimum Width		0.100	Set the minimum width that meets requirements
Maximum Width		1.000	Set the maximum width that meets requirements
Judgment Mode	Any/Continuous	Any	Any: When any number of regional width values exceeds the set outlier count, judge as NG Continuous: When several consecutive regional width values exceed the set outlier count, judge as NG
Outlier Count		1	Set to judge as NG when number of outlier values exceeds this value
Minimum Height		0.100	Set the minimum height that meets requirements
Maximum Height		1.000	Set the maximum height that meets requirements
Judgment Mode	Any/Continuous	Any	Any: When any number of regional height values exceeds the set outlier count, judge as NG Continuous: When several consecutive regional height values exceed the set outlier count, judge as NG
Outlier Count		1	Set to judge as NG when number of outlier values exceeds this value

Example Introduction

Engineering Design

1. Select Load Point Cloud tool to load required 3D point cloud image into IM0.

2. Select 3D Region tool to select region requiring plane fitting.

3. Select 3D Plane tool, using output of 3D Region tool as input, fit plane and transform point cloud.

4. Select Adhesive Path Inspection - Contour tool.

Tool Usage

1. Select input image for operation. Image number must match IM number where image is located in project.

2. Either disable Use Region Parameter or enable Region and select region type as Box, then move box to target position to surround point cloud to be measured.

Usage Tips

1. Use ROI controller on image window to drag or scale box;
2. Directly modify box start or end coordinates in calculation parameters to adjust box position and size.

3. Set parameters.

4. Check desired display content in Result Display section.

5. Click Test to check if image window and parameters meet expectations.

6. If everything is correct, click Save, then run operator in run list. View results in corresponding IM.
