-====== Preferences of Guardrail Detection =====
-This page describes only the parameters and preferences of Guardrail Detector. \\
-Full documentation about semi-automatic detectors, see [[dev:technology:3d_mapping:measurements|]].

-===== Algorithm =====
-{{  :dev:desktop:preferences:preferences_guardrail_1930.png?nolink&300|}}
-**Search Box Size**: Width and Height and **Slice thickness**\\
-Dimensions of the 'template' slice.\\
-**Search radius** and **Step trajectory**\\
-Distance of search for the similar slice around the initial position, which is determined   **step trajectory** away from previous slice along trajectory line.\\
-**Repositioning step**\\
-**Mask cell size** and **Profile min match**\\
-Slice is split into smaller cells. Cells one-by-one are compared to the cells of the next slice (presence of points inside each of them) and match percentage is determined.\\
-===== Output =====
-**Final line Distance points**\\
-Distance between vertexes of the output line.\\
-**Smooth Margin**\\
-Smoothing tolerance.
