Ottawa Airport
Testing Searidge Technologies' Surface Detection System
Ottawa
International Airport is evaluating a new system, developed by Searidge
Technologies, that detects and tracks aircraft, vehicles, humans and other
objects, on an airport with a network of "low cost" digital
imaging sensors and computer vision technology.
Searidge says its CASD
(computer-vision-based airport surface detection) system has successfully
detected and tracked targets in a variety of low visibility weather
conditions including rain, fog, high winds and snow flurries.
CASD consists of a
number of camera-sensor sets (visible light and infrared), which cover a
defined geographic area, a core processing engine, and a 3D display.
Images from the visible-light sensors are computer-enhanced to improve
daytime contrast and eliminate thermal phenomena such as heat spots on runway
surfaces, while its infrared sensors provide images in darkness and
inclement weather.
Searidge believes
CASD can offer more flexibility and functionality at a lower cost than
traditional radar and multilateration-based systems.
The system will be operational
for the next 12 months in the south-west area of the airport, and its
results will be collected and analyzed.
A brief video
demonstration of CASD is available at http://www.searidgetech.com/video_link.
