Concepts
The “Poles Analysis” extension automatically detects poles based on a point cloud and set of user-defined parameters.
Pole detection is based on the geometry of the point cloud: poles are expected to be round and standing straight. Based on this assumption the process of detecting poles can be split into 3 main steps:
- Quickly exclude areas that can not contain poles.
- Find poles candidates and check if they meet the criteria of being round and straight.
- (Optional) Exclude trees, traffic signs, and poles which are not on the ground.
More information, see Workflow on Automated Pole Detector.
Source
Use the generic workflow for Point Cloud Based Extensions to define the source file.
The method for the range of interest is 'Area', 'Path' and 'Seed points'.
Parameters
When creating a new project the parameters are read from Preferences of Detectors and basic set of the parameters is displayed on the sidebar; advanced parameters can be accessed by small grey circle above basic parameters.
Changing parameters in the sidebar influence the currently opened project immediately, while Parameters in the Preferences are only taken into account at the moment of Project creation.
Test
Before running the detector on the range of interest, use this step to test if objects are detected as expected.
Measure
Measure the object to test if the parameters are defined correctly.
Start
Run the test measurement. If the object conforms with the parameters then the message “Feature is detected” will be shown, otherwise Orbit will provide a tip on the calculated statistics and recommendation on which parameters need to be changed for this feature to be detected as a feature of interest.
Clear
Clear the current test measurement.
