Cylinder Detection

Menu:  Analyze / Cylinders

The Cylinders Detection tool enables batch detection of cylindrical objects in the point cloud. Cylinders are identified based on four key parameters:

✔ Tolerance – Maximum allowable distance between a point and the detected cylinder.
✔ Minimum Cylinder Radius – The smallest radius a cylinder must have to be detected.
✔ Maximum Cylinder Radius – The largest radius a cylinder can have to be included in the detection.
✔ Minimum Points – The minimum number of points required to define a valid cylinder.

1. Detection Parameters

Tolerance

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

• Lower values increase precision but may exclude valid cylinders.

Minimum & Maximum Cylinder Radius

• Minimum Radius – Cylinders smaller than this value will be ignored.

• Maximum Radius – Cylinders larger than this value will be ignored.

• Adjust these settings to target specific pipe sizes, columns, or structural elements.

Minimum Points

• Defines the minimum number of points needed to form a valid cylinder.

• Helps prevent false detections from sparse or noisy 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 specific areas, reducing processing time.

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

3. Running the Detection

1. Set the tolerance, radius limits, and minimum points.

2. Choose a starting point (optional).

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

4. Click “Start” to begin detection.

5. Detected cylinders will appear in the Explorer → Objects Tab → Cylinders.
