vehicles	List<Object>	List of output vehicles

vehicles parameters

Field	Type	Description
bounding_box	Object	Coordinates of a bounding box
license_plate_id	String	License plate. When the license plate cannot be detected, "" (an empty string) is output by default.
detection_id	String	UUID of an abnormal parking event, which is used to identify whether the alarm points to the same vehicle. Note that the license plate may be blocked or blurred. As a result, this field may be inaccurate.
polygon_name	String	ROI where the abnormal parking event occurs

bounding_box parameters

Field	Type	Description
x	Int	Horizontal coordinate of the upper-left corner of a bounding box
y	Int	Vertical coordinate of the upper-left corner of a bounding box
w	Int	Width of a bounding box
h	Int	Height of a bounding box
