QuercusVL Programming Manual
●
Message Data:
●
Id: unique identifier of the incidence.
●
Type: type of incidence:
○
0:
obsolete.
○
1: vehicle violating the red light sign.
○
2: vehicle stopped in a forbidden zone.
●
NumImages (NImg): number of images of the incidence.
●
ImageTimestamps (ImgTime): timestamps of each incidence image, using 3
consecutive Quercus
Timestamp
structures (maximum number of incidence
images) . Only the first
NumImages
are used.
●
VideoInformation (VideoInf): information of the generated video file. A
VideoInformation
structure is used. If no video was genrated at the incidence,
the value
Witdh
of the structure
VideoInformation
will be -1
.
●
DetectorId: identifier of the detector that generated the incidence.
●
DetectorType (DTy): type of detector that generated the real time event:
○
1: speed detector.
○
2: queue detector.
○
3: presence detector.
○
4: red light detector.
○
5: stopped car detector.
●
Speed: approximated speed of the detected vehicle; in km/h. If value is -1,
speed calculation was not possible.
●
DelayTime: the minimum time that must go by, from the moment the lights go
red, until the infringement is made, to generate a valid incidence; in
milliseconds.
●
ElapsedTime: time elapsed since the traffic light went red; in milliseconds.
●
AmberLightTime (AmberLightT): time spent with amber light active, before
turned to red and generated the incidence.
●
MaxStopTime: minimum amount of time the vehicle has to be stopped once red
light is on, in order for the offence to be generated; in milliseconds.
