3D Point Cloud Deduplication

Operator Function

Detects duplicate points in a point cloud and merges them into a single average point, thereby achieving point cloud deduplication.

Parameter Introduction

Input Parameters

Parameter	Range	Default	Description	Illustration
Input Image	0-31	0	IM number for image input
3D Datum			Can be selected by binding 基准
X			3D datum parameter X coordinate value, can be set via binding X
Y			3D datum parameter Y coordinate value, can be set via binding Y
Z			3D datum parameter Z coordinate value, can be set via binding Z
X-axis Angle	-10000000000.000-10000000000.000		3D datum parameter X-axis angle value, can be set via binding X轴角度
Y-axis Angle	-10000000000.000-10000000000.000		3D datum parameter Y-axis angle value, can be set via binding Y轴角度
Z-axis Angle	-10000000000.000-10000000000.000		3D datum parameter Z-axis angle value, can be set via binding Z轴角度

Computation Parameters

Parameter	Range	Default	Description	Illustration
Use Region Parameter	true/false	false	When enabled, uses 区域 as input; when disabled, uses 输入图像 as input
Region	2D Window/2D Circular Window/Box/Cylindrical Box/Rotated Box	Box	Manually select an appropriate ROI region Can select an existing ROI region via binding
Distance Threshold	0.0-10.0	0.01	For a pair of points, if the distance between them is less than the distance threshold, they are considered a pair of duplicate points; otherwise, they are not a duplicate point pair
Output Image	0-31	0	IM number for image output

Result Display

Parameter	Range	Default	Description	Illustration
Duplicate Points	true/false	false	Duplicate point set; if enabled, displayed in the image

Output Parameters

Name	Type	Range	Description
Result	bool	true/false	true: success false: failure
Warning	bool	true/false	true: warning present false: no warning
Message	string		Outputs success, error, or warning message; empty if no error or warning
Time	float		Operator execution time, unit: ms

Troubleshooting

No.	Exception Message	Corresponding Parameter	Solution
1	Input point cloud is empty		Load a point cloud or switch to an IM that contains a point cloud
2	The input region type is {0}, invalid region type	Region type	The region input type must be one of: 2D Window/2D Circular Window/Box/Cylindrical Box/Rotated Box

Example Introduction

Project Design

1. Select the 加载3D点云 tool to load the 3D point cloud image to be processed into IM0.

2. Select the 3D点云去重 tool.

Tool Usage

1. Select the input image to operate on. The image number must match the IM number where the image is located in the project.

2. Set the region.

3. Set the distance threshold.

4. Click 测试 to check whether the image window and parameters meet expectations.

5. After confirming no issues, click 保存, then run the operator in the run list to view the results in the corresponding IM.
