QuercusVL Programming Manual
●
Lights: description of each one of the configured lights, using 5 consecutive
Light
structures (maximum number of configurable lights). Only the first
NumLights
are used.
4.5.9. RedLightDetector
Describes a red light detector.
The structure corresponds to the version 3. Check 5. Communications protocol (old versions)
to see the older versions.
●
Header (Head): description of detector's common features, using a
DetectorHeader
structure.
●
CalculateMetrics (Calc): true if metric calculation is enabled at the detector, false
if disabled.
●
Distance: distance between the horizontal axe of the unit and the detector; in
millimetres.
●
Length: detector's length; in millimetres.
●
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.
●
FirstLoop (Loop1): coordinates (in the 5 megapixel image ) of the detector's first
loop, using a
Region
structure.
●
SecondLoop (Loop2): coordinates (in the 5 megapixel image) of the detector's
second loop, using a
Region
structure.
●
TrafficLightId: the traffic light identifier used for the red state sign. If no traffic
light has been configured, but a digital input, its value will be -1.
●
RedInput: the identifier of the digital input used for the red state sign. If no
digital input has been configured, but a traffic light, its value will be -1.
●
AmberInput: the identifier of the digital input used for the amber sign. If no
digital input has been configured (because a traffic light will be used, or because
