Detailed Description

A traffic sign.

All coordinates and orientations are relative to the global ground truth coordinate system.

Member Enumeration Documentation

Variability

enum osi3::TrafficSign::Variability

Definition of the variability of a traffic sign.

Enumerator
VARIABILITY_UNKNOWN	Variability type of sign is unknown (must not be used in ground truth).
VARIABILITY_OTHER	Other (unspecified but known) variability.
VARIABILITY_FIXED	Fixed sign, i.e. always present.
VARIABILITY_VARIABLE	Temporary or variable sign, e.g. on a sign bridge.

Member Data Documentation

id

optional Identifier osi3::TrafficSign::id = 1

The ID of the traffic sign.

\rules is_globally_unique \endrules

main_sign

optional MainSign osi3::TrafficSign::main_sign = 2

Main sign, e.g. speed limit 30 km/h

source_reference

repeated ExternalReference osi3::TrafficSign::source_reference = 4

Optional external reference to the traffic sign source.

The external reference point to the source of the traffic sign, if it is derived from one or more objects or external references.

For example, to reference a signal defined in an OpenDRIVE map the items should be set as follows:

• reference = URI to map, can remain empty if identical with definition in GroundTruth::map_reference
• type = "net.asam.opendrive"
• identifier[0] = id of t_road_signals_signal

Note

For non-ASAM Standards, it is implementation-specific how source_reference is resolved.

If an individual identification of MainSign and SupplementarySign is necessary, this should be done via multiple individual entries of this source_reference.

The value has to be repeated, because one lane segment may be derived from more than one origin segment. Multiple sources may be added as reference as well, for example, a map and sensors.

supplementary_sign

repeated SupplementarySign osi3::TrafficSign::supplementary_sign = 3

Additional supplementary signs, e.g. time limits, modifying the traffic sign.

Note

OSI uses singular instead of plural for repeated field names.
