Preferences of Crosswalk Detection

This page describes only the parameters and preferences of Crosswalk Detector.
Full documentation about semi-automatic detectors, see Basic 3D Measurement Functions.

Main Toolbar > Preferences > Detectors > Crosswalk Detector


Search radius

The algorithm searches for high-intensity points in the space of which the width is indicated by this value around the coordinates indicated by the user.

Ground margin

Within this distance above the ground, the crosswalk will be detected.

Stripe size and Space size

Fixed width of the crosswalk stripe and the distance between 2 consequent stripes.

Step 2D, Step angle and max angle

Starting from the first coordinate indicated by the user, the algorithm searches for the exact length of the crosswalk. The Step 2D value indicates the length of the step to reposition the feature. The Step Angle is used to reposition the feature.

Context radius


Return stripes

Enable returning multi-feature consisting of separate polygons for each crosswalk stripe.

Default length

Stripe length used only for visualization during the measurement.
