Plane Detection

Menu: Analyze / Planes

The Planes Detection tool allows for batch detection of planar surfaces in the point cloud. Planes are identified based on three main criteria:

✔ Detection Tolerance – The maximum allowable distance between a point and the detected plane.
✔ Minimum Area – The smallest plane area that will be considered for detection.
✔ Minimum Points – The minimum number of points required to define a plane.

1. Detection Parameters

Detection Tolerance

• Defines the maximum distance a point can be from a plane to be included in the detection.

• Smaller values ensure higher precision but may exclude some valid surfaces.

Minimum Area

• Defines the smallest surface area a plane must have to be detected.

• Larger values filter out small or insignificant planes.

Minimum Points

• Sets the minimum number of points required to define a valid plane.

• Prevents the detection of false planes from sparse data.

2. Selecting the Processing Area

Pick Starting Point

• Click “Pick” to manually select a starting point from the point cloud.

Limit by Radius

• Restricts detection to a defined radius around the starting point.

• Helps focus detection on a specific area, reducing processing time.

• ⚠ If unchecked, it is highly recommended to use a fence around the area to optimize performance.

3. Running the Detection

1. Configure the detection tolerance, minimum area, and minimum points.

2. Choose a starting point (optional).

3. Set a radius limit (recommended for faster processing).

4. Click “Start” to launch the detection.

5. Detected planes will be listed in the Explorer → Objects Tab → Planes.
