Struct Documentation¶

struct TrafficSign¶

A traffic sign.

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

Public Types

enum Variability¶

Definition of the variability of a traffic sign.

Values:

VARIABILITY_UNKNOWN = 0¶: Variability type of sign is unknown (must not be used in ground truth).

VARIABILITY_OTHER = 1¶: Other (unspecified but known) variability.

VARIABILITY_FIXED = 2¶: Fixed sign, i.e. always present.

VARIABILITY_VARIABLE = 3¶: Temporary or variable sign, e.g. on a sign bridge.

Public Members

optional Identifier osi3::TrafficSign::id = 1: The ID of the traffic sign.

optional MainSign osi3::TrafficSign::main_sign = 2: Main sign, e.g. speed limit 30 [km/h]

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.

struct MainSign¶

Main sign of the traffic sign.

../_images/OSI_MainSign.svg

Public Members

optional BaseStationary osi3::TrafficSign::MainSign::base = 1

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.

optional Classification osi3::TrafficSign::MainSign::classification = 2: The classification of the traffic sign.

struct Classification¶

Classification data for a traffic sign.

../_images/OSI_DirectionScope.svg

When constructing a MainSign, consider the use of the following members:

In order to include numerical values indicated in the sign, use TrafficSignValue::value. Accompany this value with an indication of its unit of measure given by TrafficSignValue::value_unit.
In order to include strings of text indicated in the sign, use TrafficSignValue::text. The interpretation of this text is left to a user-defined procedure.
Some traffic signs exist in two variants that have a similar semantic meaning and the property that the one results from flipping the other one around the vertical axis. The optional member vertically_mirrored has been provided to enable an explicit choice between both variants.
For signs in which an arrow symbol is included to constraint their scope, the direction_scope member has been provided to indicate the direction of the arrow from the perspective of a viewer standing right in front of the sign and looking straight towards it.

Note: The definition of the sign types is thought to be independent of the country, even if the images used in this documentation are based on the German Road Traffic Regulations (StVO).

Public Members

optional Variability osi3::TrafficSign::MainSign::Classification::variability = 1: The traffic sign is not stationary, for example a temporary traffic sign in a street construction.

optional Type osi3::TrafficSign::MainSign::Classification::type = 2: The type of the traffic sign.

optional TrafficSignValue osi3::TrafficSign::MainSign::Classification::value = 3

Additional value associated with the traffic sign, e.g. value of the speed limit.

Note: Field need not be set if traffic sign type does not require it.

optional DirectionScope osi3::TrafficSign::MainSign::Classification::direction_scope = 4

Some traffic signs have an additional arrow symbol as an additional constraint for their scope (e.g. no parking to the right). The arrow direction is given relative to the sign’s 2D image plane, i.e. as a viewer standing right in front of the sign and looking straight towards it would interpret the arrow.

The definition for left and right is according to the following temporarily constructed right-handed local coordinate system: Set z-axis to match the z-axis of the ground truth coordinate system. Set x-axis to the view normal of the traffic sign’s image (base BaseStationary::orientation x-axis). Right: direction of the local coordinate system’s positive y-axis. Left: opposite direction of the local coordinate system’s y-axis i.e. negative y-axis’,

Note: If a traffic sign image is on the ground (there is no definition for right or left). Normally, this is a road marking and not a traffic sign. Actual traffic signs lying on the ground might have been intentionally unmounted and, hence, not be in effect.

repeated Identifier osi3::TrafficSign::MainSign::Classification::assigned_lane_id = 5

The IDs of the lanes that the sign is assigned to. May be multiple if the sign is valid for multiple lanes.

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

optional bool osi3::TrafficSign::MainSign::Classification::vertically_mirrored = 6: Some traffic signs exist in two variants that have a similar semantic meaning but differ in that the symbol of the one corresponds to the specular reflection of the other with respect to the vertical axis. For some scenarios it might be relevant to choose the reflected version of a reference sign. This can be done by setting the vertically_mirrored boolean to true. As for every boolean in the protocol buffers language, the default value of vertically_mirrored is false.

optional bool osi3::TrafficSign::MainSign::Classification::is_out_of_service = 7: Boolean flag to indicate that a traffic sign is taken out of service. This can be achieved by visibly crossing the sign or covering it completely.

struct SupplementarySign¶

Additional supplementary sign modifying the main sign.

../_images/OSI_SupplementarySign.svg

Public Members

optional BaseStationary osi3::TrafficSign::SupplementarySign::base = 1

The base parameters of the supplementary traffic sign.

The orientation of the bounding box SupplementarySign::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 supplementary 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 supplementary traffic sign’s image. This x-axis points from the supplementary traffic sign’s image in the direction from where a ‘viewer’ could see the supplementary traffic sign image.

optional Classification osi3::TrafficSign::SupplementarySign::classification = 2: The classification of the supplementary traffic sign.

struct Classification¶

Classification data for a supplementary traffic sign.

When constructing a SupplementarySign, consider the use of the following members:

In order to include numerical values indicated in the sign, use TrafficSignValue::value. Accompany this value with an indication of its unit of measure given by TrafficSignValue::value_unit.
In order to include strings of text indicated in the sign, use TrafficSignValue::text. The interpretation of this text is left to a user-defined procedure.

Note: The definition of the sign types is thought to be independent of the country, even if the images used in this documentation are based on the German Road Traffic Regulations (StVO).

Public Types

enum Type

Definition of supplementary sign types.

For general supplementary signs use TYPE_TEXT. Supplementary signs with general space restrictions use TYPE_SPACE. Supplementary signs with general time restrictions use TYPE_TIME. Supplementary signs with displayed arrow directions use TYPE_ARROW. Supplementary signs constraint to one type of actors use TYPE_CONSTRAINED_TO. Supplementary signs that will exclude one type of actors use TYPE_EXCEPT. If supplementary signs combine contraints, restrictions, or plain text, Type is used in descending order in the following sequence: TYPE_EXCEPT, TYPE_CONSTRAINED_TO, TYPE_ARROW, TYPE_TIME, TYPE_SPACE, TYPE_TEXT.

Values:

TYPE_UNKNOWN = 0: Type of supplementary sign is unknown (must not be used in ground truth).

TYPE_OTHER = 1: Other (unspecified but known) type of supplementary sign.

TYPE_NO_SIGN = 2¶: There is no supplementary sign (must not be used in ground truth).

TYPE_TEXT = 41¶

Text sign.

Use it as a canvas for text-only signs:

Use TrafficSignValue::value to indicate a numerical value indicated on the sign. Accompany this value with an indication of its unit of measure given by TrafficSignValue::value_unit.
Use TrafficSignValue::text to indicate a string of text indicated on the sign.

The following table summarizes possible configurations for this kind of supplementary signs:

TYPE_SPACE = 39¶

Text sign with distance indication.

Use it as a canvas for text signs that make reference to a point or area in space:

Use TrafficSignValue::value to include the distance indicated in the sign. Accompany this value with an indication of its unit of measure given by TrafficSignValue::value_unit (e.g. [m]),
Use TrafficSignValue::text to indicate the sign’s specific text,

The following table summarizes possible configurations for this kind of supplementary signs:

TYPE_TIME = 26¶

Text sign with time indication.

Use it as a canvas for text signs that make: reference to a point in time or a time range.

Use one or more TrafficSignValue messages to include the times indicated in the sign. Accompany each value with an indication of its unit of measure given by TrafficSignValue::value_unit, e.g. [h].
For each TrafficSignValue, TrafficSignValue::value indicates the time elapsed since midnight every day.
Use the TrafficSignValue::text member of the first TrafficSignValue message to indicate the sign’s specific text.

The following table summarizes possible configurations for this kind of supplementary signs:

Note

Time interval need two TrafficSignValue messages, one to indicate their start and one to indicate their end.
In case more than one time range is required, the TrafficSignValue::value member of the first TrafficSignValue message is interpreted as the beginning of the first interval, the TrafficSignValue::value member of the second TrafficSignValue message is interpreted as the end of the first interval, and so on.

TYPE_ARROW = 30¶

The following tables summarize possible configurations for this kind of supplementary signs:

Also, some of the German StVO traffic signs denoting traffic actors for which the main sign’s regulation applies exclusively can be constructed.

Note: In the German StVO, these signs typically include the word “Nur”.

In addition, some of the German StVO supplementary signs with actors that receive an explicit allowance to use the street or the shoulder can be constructed:

Finally, the signs

can be incorporated.
