class py123d.datatypes.detections.TrafficLightDetectionWrapper[source]¶

The TrafficLightDetectionWrapper is a container for multiple traffic light detections. It provides methods to access individual detections as well as to retrieve a detection by lane id. The wrapper is is used in to read and write traffic light detections from/to logs.

Public Data Attributes:

traffic_light_detections

List of individual TrafficLightDetection.

Public Methods:

get_detection_by_lane_id(lane_id)

Retrieve a traffic light detection by its lane id.

property traffic_light_detections: List[TrafficLightDetection]¶: List of individual TrafficLightDetection.

get_detection_by_lane_id(lane_id)[source]¶

Retrieve a traffic light detection by its lane id.

Parameters:: lane_id (int) – The lane id to search for.
Return type:: Optional[TrafficLightDetection]
Returns:: The traffic light detection for the given lane id, or None if not found.

class py123d.datatypes.detections.TrafficLightDetection[source]¶
