Linear Image Acquisition System
This is an electronic circuit with embedded software that can scan
a moving video signal in real-time while eliminating pick-up redundancy.
The system is currently in use for monitoring train traffic throughout
North America. It uses a linear camera and incorporates many leading-edge
Synchronous Sampler for Four Cameras
This is an electronic interface that is placed between the
cameras and a conventional videotape recorder.
The interface captures analog images (frames) from each
camera, converts them into a digital format, processes them,
and reconverts them to analog format for recording on the
Every image from a given camera is interlaced with those
from the other cameras. The system thus captures the sweep
of each camera 15 times per second, for example, instead
of switching from one to another every quarter of a second.
A system that handles images from four cameras, allocating
two seconds to each, would lose six seconds of imagery for
every scanning cycle.
With this system, it is also possible to reassemble and
view the images produced by any one of the cameras. In addition,
a serial port allows printing of any frame.
Video Recognition System
Initially developed for railways, this system consists of
an electronic circuit and embedded software, and uses video
recognition to determine the direction of a train, count
its cars and determine its speed.
This is a sophisticated video recognition system that uses
a spectral power-density processor to establish correlations
based on fast Fourier transformations. The background landscape,
different types of cars, weather conditions (snow or rain)
and the time of day (sunlight level) do not affect recognition.
