◆ Geometry

enum osi3::DetectedTrafficSign::DetectedMainSign::Geometry

Definition of traffic sign geometries.

Enumerator
GEOMETRY_UNKNOWN	Geometry of the traffic sign is unknown (must not be used in ground truth).
GEOMETRY_OTHER	Geometry of the traffic sign is unspecified (but known).
GEOMETRY_CIRCLE	Traffic sign has a circular geometry. (0 corners)
GEOMETRY_TRIANGLE_TOP	Traffic sign has a triangular geometry pointing to the top. (3 corners)
GEOMETRY_TRIANGLE_DOWN	Traffic sign has a triangular geometry pointing down. (3 corners)
GEOMETRY_SQUARE	Traffic sign has a square geometry. (4 corners)
GEOMETRY_POLE	Traffic sign that has a pole geometry. (height is bigger than width e.g. pole indicating highways exit in xx m). (4 corners)
GEOMETRY_RECTANGLE	Traffic sign has a rectangle geometry. (width is bigger than height e.g. one-way) (4 corners)
GEOMETRY_PLATE	Traffic sign that has an oversize rectangle geometry. (4 corners) E.g. direction plates on highway or city signs.
GEOMETRY_DIAMOND	Traffic sign has a diamond geometry. (4 corners)
GEOMETRY_ARROW_LEFT	Traffic sign has a geometry of an arrow pointing to the left. (5 corners)
GEOMETRY_ARROW_RIGHT	Traffic sign has a geometry of an arrow pointing to the right. (5 corners)
GEOMETRY_OCTAGON	Traffic sign has an octagon geometry. (8 corners)

◆ candidate

repeated CandidateMainSign osi3::DetectedTrafficSign::DetectedMainSign::candidate = 1

A list of candidates for this traffic sign as estimated by the sensor.

Note: OSI uses singular instead of plural for repeated field names.

◆ base

optional BaseStationary osi3::DetectedTrafficSign::DetectedMainSign::base = 2

The base parameters of the traffic sign.

The orientation of the bounding box base ( BaseStationary::orientation ) is defined as follows:

The z-axis of the given BaseStationary::orientation is the vector from the bottom to the top of the traffic sign's 2D image plate. (Normally it is equal to the ground truth z-axis.)

The x-axis of the given BaseStationary::orientation is view normal of the traffic sign's image.

This x-axis points from the traffic sign's image in the direction from where a 'viewer' could see the traffic sign image.

◆ base_rmse

optional BaseStationary osi3::DetectedTrafficSign::DetectedMainSign::base_rmse = 3

The root mean squared error of the base parameters of the detected traffic sign.

TrafficSign::MainSign::base has to be identical for all candidate traffic signs.

◆ geometry

optional Geometry osi3::DetectedTrafficSign::DetectedMainSign::geometry = 4

The estimated geometry of the traffic sign.
