3D Plane Fitting

Operator Function

Fit a plane based on the input region parameters and output the plane parameters. If the transform point cloud option is enabled, adjust the input point cloud region to the xoy plane based on the plane parameters.

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	Image
Estimate Plane	true/false	true	If enabled, perform plane fitting based on the input region and output the corresponding plane parameters to registers
Transform Point Cloud	true/false	true	If enabled, adjust the input point cloud image to the xoy plane, i.e., the zero plane
Region			Set the region range for plane estimation and point cloud transformation
Output Image	0-8	0	IM number for image output

Result Display

Parameter	Range	Default Value	Description	Illustration
Plane	true/false	false	Plane fitted using the input region. If enabled, display in the image
ROI Point Set	true/false	false	Region point set selected by ROI box. If enabled, display in 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
plane	plane		Plane parameters

Exception Troubleshooting

No.	Exception Information	Corresponding Parameter	Solution
1	No algorithm function specified! Please select at least one function		Select at least one function from Estimate Plane and Transform Point Cloud
2	Input value is {0}, invalid region type	Region Type	Only window2d, box, pointset supported
3	Region is empty		1. Check if input point cloud is empty 2. Check if ROI region selects point cloud 3. Check if bound pointset is empty

Example Introduction

Engineering Design

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

2. Select the 3D Region Operation tool to obtain the region needed for plane fitting.

3. Select the 3D Plane Fitting tool to measure the profile step from point to point and point to line respectively.

Tool Usage

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

2. Set the region:

Bind the region obtained from the previous step's 3D Region Operation tool.

3. Set the parameters.

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

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

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