Introduction
THE NEED OF EFFICIENT SPEED
MEASUREMENT
RADAR GUN AND RADAR DETECTOR.
MEASURING SPEED USING CCTV CAMERA
DOPPLER EFFECT
FREQUENCY CHANGE DUE TO RELATIVE MOVEMENT OF SOURCE
Frequency increases when source moves towards observer
Frequency decreases when source moves away from observer
Gaussian Mixture Model
A pixel in the frame is designated as a background or foreground using Gaussian PDF as a reference of the three colour components [R G B].
Coordinate Tracking
Coordinate of bbox is tracked and placed in every frame using blob analysis
ADVANTAGES
Cost effective.
Real time updates.
Multiple vehicle tracking.
Effective law enforcement.
As surveillance cameras already installed no additional hardware required.`
