class Metadata(BaseMetadata):
This JSON object contains metadata about the annotation file itself.
Class Variable | acquisition |
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 |
Specifies the acquisition method used for obtaining the data in this file. |
Class Variable | acquisition |
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 |
The version of the aveas_openlabel library used to generate this file. |
Class Variable | projection |
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 |
Specifies the usage rights of the data. |
Class Variable | threshold |
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 |
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 |
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. |
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'
