3D Point Cloud Operations

Operator Function

Perform operations on multiple point clouds to output a new point cloud.

Parameter Introduction

Input Parameters

Parameter	Range	Default Value	Description	Illustration
Input Image	0-8	0	The IM number for image input
Input Image 2	0-8	1	The IM number for image input

Calculation Parameters

Parameter	Range	Default Value	Description	Illustration
Mode	Point Cloud Union/Point Cloud Intersection/Point Cloud Difference	Point Cloud Union	Point Cloud Union: Calculate the union of input point clouds. Point Cloud Intersection: Calculate the intersection of input point clouds. Point Cloud Difference: Subtract points common with the second point cloud from the first point cloud; the remaining part of the first point cloud becomes the output.
Output Image	0-8	2	The IM number for image output

Output Parameters

Name	Type	Range	Description
Result	bool	true/false	true for success false for failure
Warning	bool	true/false	true indicates there is a warning false indicates there is none
Message	string		Outputs success, error, or warning information; if there is no error or warning, it is empty
Time	float		Operator execution time, unit: ms

Tip

For more detailed explanations of parameter types, please refer to Type Definitions

Exception Troubleshooting

No.	Exception Information	Corresponding Parameter	Solution
1	Input point cloud is empty		Confirm if IM contains valid points; if no valid points, load point cloud or switch to IM with valid points
2	Input point cloud operation type is {0}, invalid operation type		Mode must be one of: Union/Intersection/Difference
3	Output point cloud is empty		Adjust input point clouds or operation mode

Example Introduction

Engineering Design

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

2. Select the Load Point Cloud tool to load the second 3D point cloud image into IM1;

3. Select the 3D Point Cloud Operations tool to perform Point Cloud Union, Point Cloud Intersection, and Point Cloud Difference operations respectively.

Tool Usage

1. Select the input images for operation; the image numbers must match the IM numbers where the images are located in the project.

Input Point Cloud 1:

Input Point Cloud 2:

2. Set parameters

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

4. If there are no issues, click Save, then run the operator in the run list to view the results in the corresponding IM
