Detailed Description

A road marking in the environment as detected by the sensor.

The figure shows two STOP road markings (DetectedRoadMarking::CandidateRoadMarking::classification). STOP RoadMarking::Classification::type == RoadMarking::Classification::TYPE_TEXTUAL_TRAFFIC_SIGN is marked, STOP RoadMarking::Classification::type == RoadMarking::Classification::TYPE_SYMBOLIC_TRAFFIC_SIGN is not marked.

Member Data Documentation

◆ header

optional DetectedItemHeader osi3::DetectedRoadMarking::header = 1

Common information of one detected item.

◆ base

optional BaseStationary osi3::DetectedRoadMarking::base = 2

The base parameters of the road marking.

The orientation of the bounding box base BaseStationary::orientation is defined as follows: The z-axis of the BaseStationary::orientation is the vector from the 'bottom' to the 'top' of the road marking's (i.e. painted traffic sign) 2D image area. (Normally it is in the ground truth xy-plain.) The x-axis of the BaseStationary::orientation is the view normal of the road marking's 2D image area. Normally this x-axis points to the sky.

Note: If a valid unidirectional road marking is assigned to the host vehicle's current lane and the driving direction of the latter roughly matches the z-axis of the base BaseStationary::orientation then the road marking is of relevance to (i.e. in effect for) the host vehicle.

◆ base_rmse

optional BaseStationary osi3::DetectedRoadMarking::base_rmse = 3

The root mean squared error of the base parameters of the detected road marking.

RoadMarking::base has to be identical for all candidate road markings.

◆ candidate

repeated CandidateRoadMarking osi3::DetectedRoadMarking::candidate = 4

A list of candidates for this road marking as estimated by the sensor.

◆ color_description

optional ColorDescription osi3::DetectedRoadMarking::color_description = 5

The visual color of the material of the road marking.

Note: This does not represent the semantic classification but the visual appearance. For semantic classification of the road marking use the color field in CandidateRoadMarking::classification.
