2D Line Intersection

Operator Function

Input the parameters of lines/segments, determine whether two objects intersect within the set tolerance range, and if they do, output the intersection coordinates to the register.

Parameter Introduction

Input Parameters

Parameter	Range	Default Value	Description	Illustration
Input Image	0-8	0	IM number for image input

Calculation Parameters

Parameter	Range	Default Value	Description	Illustration
Line 1	2D Line/2D Segment	2D Segment	Manually set appropriate line or segment Can bind to select existing R line or segment
Line 2	2D Line/2D Segment	2D Segment	Manually set appropriate line or segment Can bind to select existing R line or segment

Extend the line segments to find the intersection point, α is the angle between the lines, P(x,y) is the intersection point coordinates.

Result Display

Parameter	Range	Default Value	Description	Illustration
Line 1	true/false	false	If enabled, display the first line on the image
Line 2	true/false	false	If enabled, display the second line on the image
Intersection Point	true/false	false	If enabled, display the intersection point of the two lines on the image

Output Parameters

Name	Type	Range	Description
Result	bool	true/false	true for success false for failure
Warning	bool	true/false	true indicates a warning false indicates no warning
Message	string		Output success, error, or warning messages. Empty if no error or warning.
Time	float		Operator execution time, unit: ms
point	point2d		Intersection point XY information of the two lines
angle	float		Angle information at the intersection of the two lines

Exception Troubleshooting

No.	Exception Information	Corresponding Parameter	Solution
1	Parallel, no intersection point		The input lines are parallel and have no intersection point
2	Input image is empty		Check if the input image is empty

Example Introduction

Engineering Design

1. Select the Load Image tool to load the required 2D image to IM0.

2. Select two 2D Line tools to obtain two lines respectively.

3. Select the 2D Line Intersection tool.

Tool Usage

1. Select input image IM0.

2. Bind the two lines output by the previous 2D Line tools as Line 1 and Line 2.

3. Check the content you want to display in the result display section.

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

5. If there are no issues, click Save. Run the operator in the run list, and then view the running results in the corresponding IM.
