Traffic​Signal​Head​Recognition

Message Summary

message TrafficSignalHeadRecognition

The container provided with information regarding the detection of a traffic signal head and its lights / colors.

Include: sdii.v3.3.1.proto

Properties

Field Type Label Description
time​Stamp​UTC_​ms double required

Timestamp of the message

position​Offset Position​Offset optional

Describes the relative position of the traffic signal in respect to the vehicle and the vehicle reference axis. Datatype changed from Vector to PositionOffset through v3.3.0 v2 fix

traffic​Signal​Design​Type Traffic​Signal​Head​Design​Type​Enum optional

The main design type if identifyable.

traffic​Signal​Head​Orientation​Type Traffic​Signal​Head​Orientation​Type​Enum optional

The orientation of the traffic signal head.

traffic​Signal​Light​Color​Bitfield int32 optional

A bitfield that references the colorization and the state of the individual traffic lights. The bitfield is grouped by 5bits per light starting with the most upper or left light. Every 5 bit pair is divided in 2 bits for the state and 3 bits for the color. State-Bits (0,1): 0=off, 1=on, 2 = blinking Color-Bits (2,3,4): 0=unknown; 1=red; 2=yellow, 3=green;4=white;5=reserved;6=reserved; Example: 001.00 010.00 011.01 1=r off 3=g on 2=y off Example: 001.00 010.10 011.00 1=r off 3=g off 2=y blinking

lane​Reference​ID int32 optional

If lane recognition is activated and the reference between traffic signal and lane is known, the reference to a reference ID can be provided. The reference ID is a local ID within a message and not persisted over multiple messages.

object​Reference​ID int32 optional

If the Traffic Signal is provided with an object Type (e.g. a pole), then an object Reference can be used to identify a traffic Signal and that object to be correlated. The object ID is local within a message and not persisted over multiple messages.

extension​Container Extension​Container repeated

Contains the description and byte value of an dynamic extension content, that is undefined in this Specification.
