Adhesive Path Inspection - Trajectory

Operator Function

Manually select trajectory points of the adhesive path on a 2D image to measure break conditions, width, height, and edge margins of the adhesive path. Suitable for point cloud images with height transitions around the adhesive path.
Before using the operator, the adhesive path point cloud needs to be adjusted to a reference plane
Note: This operator requires ordered point cloud input and its corresponding 2D image (each point in the point cloud should correspond one-to-one with pixels in the 2D image)

Parameter Introduction

Input Parameters

Parameter	Range	Default Value	Description	Illustration
Input Image	0-8	0	The IM number for image input
Input Point Cloud	0-8	1	The IM number for point cloud input

Calculation Parameters

Parameter	Range	Default Value	Description	Illustration
Trajectory			Point set selected by user on 2D image
Smoothing Factor	0.0-1.0	0.0	Smoothness of trajectory on 2D image
Contour Width		20.0	Set the width for extracting contours
Contour Interval		10.0	Set the interval for extracting contours
Reference Height		0.0	Input reference baseline for height
Detection Height		0.0	Input comparison height value to distinguish adhesive path
Minimum Points Above Detection Height		10	Set threshold for number of points in contour above detection height. If below this threshold, judged as broken adhesive
Height Measurement	true/false	false	If enabled, measure height information of adhesive path
Width Measurement			When enabled, measure adhesive path width values
Width Search Mode	Inside-Out/Outside-In	Outside-In	Set mode for searching adhesive width points. When mode is Inside-Out, search from contour center point to both ends; when mode is Outside-In, search from contour start/mid point toward center
Edge Margin Measurement	true/false		Only available when width measurement is enabled. Measure edge margins of contour (distance from contour start point to left width point and from contour end point to right width point)
Break Result Judgment			Set parameters for judging broken adhesive
Height Result Judgment			Set parameters for judging whether height meets requirements
Width Result Judgment			Set parameters for judging whether width meets requirements
Edge Margin Result Judgment			Set parameters for judging whether edge margins meet requirements
Judgment Mode	Continuous/Any	Any	Set method for judging outliers. Set this value to n. If judgment mode is Any, then if n outliers appear in all contours, the result is judged as unqualified; if judgment mode is Continuous, then if n consecutive outliers appear in consecutive contours, the result is judged as unqualified
Outlier Count			Set number of outliers. When exceeded, the result is judged as unqualified
Minimum Value		0.1	Set minimum value for height/width/edge margin to be judged as qualified
Maximum Value		1.0	Set maximum value for height/width/edge margin to be judged as qualified
