Detailed Description

Classification of a lane boundary.

Image Intersection

Classification for lane boundaries lb2 and lb9:

type = TYPE_DASHED_LINE

color = COLOR_WHITE

Classification for lane boundaries lb1, lb3, lb4, lb7, lb8, lb10, lb11, lb12 and lb14:

type = TYPE_SOLID_LINE

color = COLOR_WHITE

Classification for lane boundaries lb5, lb6 and lb13:

type = TYPE_CURB

Note: In the example, the symbols l1, l2, ... and lb1, lb2, ... stand for the lane ids and lane boundary ids respectively, i.e. for integers (uint64). The symbols cl1, cl2, ... represent the osi3::Lane::Classification::centerline elements of the lanes with the respective ids.

Member Enumeration Documentation

◆ Type

enum osi3::LaneBoundary::Classification::Type

The lane boundary type.

There is no special representation for double lines, e.g. solid / solid or dashed / solid. In such cases, each lane will define its own side of the lane boundary.

Enumerator
TYPE_UNKNOWN	The type of lane boundary is unknown. Value must not be used in ground truth.
TYPE_OTHER	Unspecified but known type of lane boundary. Consider proposing an additional type if using TYPE_OTHER.
TYPE_NO_LINE	An invisible lane boundary.
TYPE_SOLID_LINE	A solid line at the lane boundary.
TYPE_DASHED_LINE	A dashed line at the lane boundary.
TYPE_BOTTS_DOTS	A lane boundary consisting of Botts' dots (multiple Botts dots).
TYPE_ROAD_EDGE	A lane boundary formed by the road's edge. The road edge is the end of the (paved) road surface.
TYPE_SNOW_EDGE	A lane boundary formed by a snow edge that may be on the road surface.
TYPE_GRASS_EDGE	A lane boundary covered by grass.
TYPE_GRAVEL_EDGE	A lane boundary covered by gravel.
TYPE_SOIL_EDGE	A lane boundary covered by soil.
TYPE_GUARD_RAIL	A guard rail.
TYPE_CURB	A curb.
TYPE_STRUCTURE	A structure (e.g. building or tunnel wall).
TYPE_BARRIER	A barrier to guide vehicles and to prevent them from entering other lanes (e.g. a concrete barrier on a highway).
TYPE_SOUND_BARRIER	A sound barrier.

◆ Color

enum osi3::LaneBoundary::Classification::Color

The semantic color of the lane boundary in case of a lane markings.

Lane markings that alternate in color must be represented by individual LaneBoundary segments.

Note: The color types represent the semantic color classification of lane markings only. They do not represent an actual visual appearance.

Enumerator
COLOR_UNKNOWN	Color of marking is unknown. Value must not be used in ground truth.
COLOR_OTHER	Other (unspecified but known) color.
COLOR_NONE	Marking without color. Used to represent logical boundaries without actual physical markings at the respective position. Value may be used in ground truth only.
COLOR_WHITE	Marking with white color.
COLOR_YELLOW	Marking with yellow / orange-yellow color.
COLOR_RED	Marking with red color.
COLOR_BLUE	Marking with blue color.
COLOR_GREEN	Marking with green color;.
COLOR_VIOLET	Marking with violet color.
COLOR_ORANGE	Marking with orange color.

◆ type

optional Type osi3::LaneBoundary::Classification::type = 1

The type of the lane boundary.

◆ color

optional Color osi3::LaneBoundary::Classification::color = 2

The semantic color of the lane boundary in case of lane markings.

Note: The color types represent the semantic classification of lane markings only. They do not represent an actual visual appearance.

◆ limiting_structure_id

repeated Identifier osi3::LaneBoundary::Classification::limiting_structure_id = 3

The ids of StationaryObject which limit the corresponding lane.

This field must be set if the type is set to TYPE_STRUCTURE

Rules: refers_to: StationaryObject
