ladar detection tracking
In our previous work,we reported a system that
monitors an intersection using a network of horizontal laser
scanners.This paper focuses on an algorithm for moving-object
detection and tracking,given a sequence of distributed laser scan
data of an intersection.The goal is to detect each moving object
that enters the intersection;estimate state parameters such as
size;and track its location,speed,and direction while it passes
through the intersection.This work is unique,to the best of the
authors’knowledge,in that the data is novel,which provides new
possibilities but with great challenges;the algorithm is the first
proposal that uses such data in detecting and tracking all moving
objects that pass through a large crowded intersection with focus
on achieving robustness to partial observations,some of which
result from occlusions,and on performing correct data associa-
tions in crowded situations.Promising results are demonstrated
using experimental data from real intersections,whereby,for 1063
objects moving through an intersection over 20 min,988 are
perfectly tracked from entrance to exit with an excellent tracking
ratio of 92.9%.System advantages,limitations,and future work
are discussed.
