This page describes only the parameters and preferences of Automated Traffic Signs Detection.
Full documentation about concept, workflow and sidebar, see Automated Feature Extraction.
General concepts of Detectors Preferences, see Preferences of Detectors.
Basic Parameters
Sign Points Min
The minimum number of high reflective points per sign.
Width Min
Minimum for a traffic sign.
Proximity Distance
Proximity distance to define points to be from the same traffic sign.
Advanced Parameters
Algoritm
Trajectory section
The size of sections to scan the trajectory with.
Adapt Reflectivity checkbox
Use an adaptive reflectivity threshold to detect signs, based on the reflectivity of their surroundings.
Reflectivity Min
Minimum reflectivity threshold to detect signs with.
Reflectivity Null
Minimum reflectivity to assume. Reflectivities below this value are not considered in the detection.
Max High Reflectivity Pts Count
Number of points to define the maximal reflectivity in a set of points.
Cluster Points Min
The minimum amount of points in the cluster to be considered in further processing.
Horizontal Slice Z size
Z size of a horizontal slice yo analyze the candidate.
Thickness Max
The maximum thickness of a traffic Sign.
Height Min
Minimal height of a traffic sign.
Neighborhood Dist
Maximum XY distance around a candidate to evaluate traffic sign.
Tolerance Dist
A maximum inclination traffic sign is allowed to have (calculated from perfectly vertical).
Detect Sign Shape
Should the shape of the sign be in the detected features?
Reposition Step
The repositioning step to identify the shape.
Match Percent Min
The minimal match percentage for both feature points inside shape and shape unit cells.
Output
Get selection per feature
Get a selection file of the points that belong to the feature.
Get selection all features
Get a file with the detected features.
Get feature Images
Should get images of the feature?
Images Count
The Number of images that should be selected of each detected feature.
Print Images
Should images be printed?
