dc.description.abstract |
A generic and robust approach for the real-time detection of people and vehicles
from an Unmanned Aerial Vehicle(UAV) is an important goal within the framework
of fully autonomous UAV deployment for aerial reconnaissance andsurveillance.
Here we present an approach for the automatic detection of vehicles based on
using multiple trainedcascaded Haar classifiers with secondary confirmation in
thermal imagery. Additionally we present a related approachfor people detection
in thermal imagery based on a similar cascaded classification technique
combining additionalmultivariate Gaussian shape matching. The results presented
show the successful detection of vehicle and people undervarying conditions in
both isolated rural and cluttered urban environments with minimal false positive
detection.Performance of the detector is optimized to reduce the overall false
positive rate by aiming at the detection of each objectof interest (vehicle/
person) at least once in the environment (i.e. per search patter flight path)
rather than every object ineach image frame. Currently the detection rate for
people is ~70% and cars ~80% although the overall episodic objectdetection rate
for each flight pattern exceeds 90%. |
