IntelliDAR

Intelligent video-based Detection and Range Processing System

IntelliDAR™, Intelligent video-based Detection and Range Processing System, comprises a series of video cameras networked together to provide a real-time view of a given area. The video image data captured by the cameras is then processed using a sophisticated set of algorithms in order to obtain specific information such as:
a) Detection of new target(s) in a scene (aircraft, vehicles, animals)
b) The positional reference of the detected target(s)
c) Specific attributes of the detected target (shape, speed, heading)

This data is then processed much like typical RADAR data – a ‘target’ or ‘track’ is associated with an object and can be fed into other systems, such as a ground control display used by air traffic controllers.

Intelligent Vision Systems

In general, intelligent vision systems are designed to assist a human operator by providing real-time functionality for immediate diagnostics and, when necessary, quick and effective action. Intelligent vision systems have proven very useful in many different sectors, including the transportation in general, and specifically to streamline operation processes and safety enhancement in the aviation industry.

Thermal Imaging

The ability to monitor airport ground traffic in low visibility and adverse weather conditions is critical for controllers to perform their tasks. In those situations, thermal imaging can be coupled with daylight/lowlight camera sensors to detect and track targets moving on the airport surface in all lighting conditions.
Depending on specific applications, intelligent vision system can leverage thermal imaging technology to see farther and recognize targets in more detail in the darkest areas. Aircrafts, vehicles, and people appear as high-contrast targets against the background thus giving the system the ability to capture images even in fog, dust, smoke and adverse weather. This greatly enhances the traffic information provide to the air traffic control tower and user empowering them to make timely traffic management decisions with high degree of confidence.

Weather Visibility Assessment

Automated visibility assessment has drawn a growing interest in the last decade. Applications for visibility sensing include airport weather systems (synoptic and runway visual range), road weather systems, air quality studies, and fog warning networks. Still today, visibility estimation by a human observer is commonly used, especially in small airports. Runway Visual Range (RVR) is a value that is computed by a forward scatter meter system. Runway visibility is estimated on the runway, often by counting runway lights. This estimation is usually performed by an on site human observer but can sometime be accomplished offsite with images taken from digital camera sensors. Typically the RVR is measured in increments of 100 feet up to 1,000 feet, increments of 200 feet from 1,000 feet to 3,000 feet, and increments of 500 feet above 3,000 feet to 6,000 feet.
