Traffic Signs Analysis

This page describes the Orbit desktop extension “Traffic Signs Analysis”.

Main Toolbar > Extract > Traffic Signs Analysis


The “Traffic Signs Analysis” extension automatically detects traffic signs based on a point cloud and set of user-defined parameters.

Traffic signs detection is based on point cloud reflectivity as well as shape recognition. Traffic signs are expected to have a high percentage of highly reflective points and the shape should be: triangle, round or square.


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'.


When creating a new project preset parameters are copied from the Detector Preferences. Basic parameters are displayed on the sidebar, advanced parameters can be accessed by the grey circle icon 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.


Before running the detector on the range of interest, use this step to test if objects are detected as expected.


Measure the object to test if the parameters are defined correctly.


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 the current test measurement.
