3D Point Cloud Interpolation

Operator Function

Based on the input organized point cloud, perform interpolation on the point cloud according to the number of interpolation points to obtain 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 Note: This operator requires organized point cloud as input

Calculation Parameters

Parameter	Range	Default Value	Description	Illustration
Interpolation Points per Row		0	Number of points to interpolate between two adjacent points in each row. Maximum 3 points can be inserted.
Interpolation Points per Column		0	Number of points to interpolate between two adjacent points in each column. Maximum 3 points can be inserted.
Algorithm	Nearest Neighbor Interpolation	Nearest Neighbor Interpolation	Nearest Neighbor Interpolation: Uses the nearest point in the neighborhood of the current interpolation position as the interpolation result.
Neighborhood Points	4 Neighbors/8 Neighbors/24 Neighbors	4 Neighbors	4 Neighbors: Search 4 adjacent surrounding points 8 Neighbors: Search 8 adjacent surrounding points 24 Neighbors: Search 24 adjacent surrounding points
Output Image	0-8	0	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

Exception Troubleshooting

No.	Exception Information	Corresponding Parameter	Solution
1	Input point cloud is empty		Check if input point cloud is empty
2	Only supports organized point cloud		Input organized point cloud
3	The input value is {0}, invalid neighborhood search method	Neighborhood Points	Only supports 4 neighbour, 8 neighbour, 24 neighbour
4	The input value is {0}, invalid algorithm	Algorithm	Only supports Nearest Neighbour

Example Introduction

Engineering Design

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

2. Select the 3D Point Cloud Interpolation tool.

Tool Usage

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

2. Set Interpolation Points per Row, Interpolation Points per Column, Neighborhood Points, and Output Image 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.
