aveas_openlabel.metadata.Metadata

class documentation

class Metadata(BaseMetadata):

This JSON object contains metadata about the annotation file itself.

Class Variable	`acquisition_date`	The date on which the data were acquired in the format yyyy-MM-ddTHH:mm:ss.FFFZ. Here, 'T' is used as time designator. '.' is used as separator for the following millisecond portion.
Class Variable	`acquisition_method`	Specifies the acquisition method used for obtaining the data in this file.
Class Variable	`acquisition_partner`	Institution or company involved in recording the data in this file. This is a free-text field that may contain copyright information.
Class Variable	`aveas_schema_version`	The version of the aveas_openlabel library used to generate this file.
Class Variable	`opendrive`	The name of the OpenDRIVE file which contains specifications that fields in this OpenLABEL refer to. The OpenDRIVE file has to use the projection string indicated under "Metadata.projection_string".
Class Variable	`projection_string`	The geographic reference system used for the coordinates in this OpenLABEL-file and in corresponding OpenDRIVE-files. Projection strings follow official parameter sets for proj-strings from EPSG.
Class Variable	`right_of_use`	Specifies the usage rights of the data.
Class Variable	`threshold_gttc`	Traffic participants with a geometrical time-to-collision (gTTC) value lower than this threshold will appear in the `Impact__gTTC__ObjectIds` and `Impact__gTTC__Values` attributes of this file.
Class Variable	`threshold_pret`	Traffic participants with a predicted encroachment time (PrET) value lower than this threshold will appear in the `Impact__PrET__ObjectIds` and `Impact__PrET__Values` attributes of this file.
Class Variable	`threshold_thw`	Traffic participants with a time headway (THW) value lower than this threshold will appear in the `Impact__THW__ObjectIds` and `Impact__THW__Values` attributes of this file.

acquisition_date: str = ¶

The date on which the data were acquired in the format yyyy-MM-ddTHH:mm:ss.FFFZ. Here, 'T' is used as time designator. '.' is used as separator for the following millisecond portion.

yyyy: Year (four digits), ex. 2021
MM: Month with leading zero, ex. 09
dd: Day in month with leading zero
mm: Minutes with leading zero
ss: seconds with leading zero
FFF: Milliseconds with leading zeros
Z: 'Z' if the time zone is UTC, '±[hh]:[mm]', '±[hh][mm]', or '±[hh]' otherwise, ex. '+0100'

acquisition_method: AcquisitionMethod = ¶

Specifies the acquisition method used for obtaining the data in this file.

acquisition_partner: str = ¶

Institution or company involved in recording the data in this file. This is a free-text field that may contain copyright information.

aveas_schema_version: Literal['0.4.17'] = ¶

The version of the aveas_openlabel library used to generate this file.

opendrive: str = ¶

The name of the OpenDRIVE file which contains specifications that fields in this OpenLABEL refer to. The OpenDRIVE file has to use the projection string indicated under "Metadata.projection_string".

projection_string: str = ¶

The geographic reference system used for the coordinates in this OpenLABEL-file and in corresponding OpenDRIVE-files. Projection strings follow official parameter sets for proj-strings from EPSG.

right_of_use: RightOfUse = ¶

Specifies the usage rights of the data.

threshold_gttc: float = ¶

Traffic participants with a geometrical time-to-collision (gTTC) value lower than this threshold will appear in the Impact__gTTC__ObjectIds and Impact__gTTC__Values attributes of this file.

threshold_pret: float = ¶

Traffic participants with a predicted encroachment time (PrET) value lower than this threshold will appear in the Impact__PrET__ObjectIds and Impact__PrET__Values attributes of this file.

threshold_thw: float = ¶

Traffic participants with a time headway (THW) value lower than this threshold will appear in the Impact__THW__ObjectIds and Impact__THW__Values attributes of this file.
