3D Hole Filling

Function

Grid the input point cloud on the XOY plane, then perform linear interpolation on the point cloud height in the holes to fill the point cloud in the holes.

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
Grid Length		0.050	Set the side length for grid division. Smaller values represent finer grid division, but processing time increases accordingly. Larger values result in larger grid divisions, showing an effect similar to downsampling.
Search Radius		5.000	In the gridded point cloud, the search radius when searching for valid points around hole points. The larger this value, the greater the influence of surrounding points on the hole point.
Output Image	0-8	0	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 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

Exception Troubleshooting

No.	Exception Information	Corresponding Parameter	Solution
1	Input value is {0}, please increase the grid length parameter value	Grid Length	Increase grid length => point cloud distance
2	Point cloud hole filling failed		Check if input point cloud 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 Hole Filling tool.

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 parameters.

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

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