multifunctional vehicle sensory system based on 3d space reconstruction

MULTIFUNCTIONAL VEHICLE SENSORY SYSTEM BASED ON 3D SPACE RECONSTRUCTION

The aim of the project• to realize prototype of new vehicle detector for purposes of traffic automation

The principle of detection• monitoring of junction with 4x4 cameras

• 3D space reconstruction

• based on 2D + perspective geometry

• schematic modelling of moving vehicles (classification of vehicles, speed etc.)

• detection of vehicle presence on determined area of perception

K/tekes/3D projekt angol

Fields of application

• junction control

• centralized traffic control

• special traffic influencing systems

• counting of vehicles with classification

• speed measurement

• monitoring of complex traffic situations

• virtual camera

The results of project

Application in the field of junction control

• functional compatibility with usual detectors

sensitivity, hysteresis of detection

compensation of presence, holding time

• interface unit, compatible with usual detector cards

• the speciality of the developed system:

simultaneous detection of vehicles and pedestrians

detection depending on dierction of movement

detection only of starting pedestrians

Application in the field of traffic data acquisition

• the realized altorithms result directly most of derivative informations

vehicle categories

length

width, heigth

speed

queue length

• the speciality of the developed system:

collection of video information

picture transmission to the processing centre (in case of on-line connection)

Application in the field of special traffic influencing systems

• direct detection on special incidents, not locally

changing lanes, movement in wrong dierction (handling the velocity as vector)

standing vehicle, strange object on the road (speed measurement)

presence in bus lane (vehicle classification)

• the speciality of the developed system:

storage of picture series documenting the circumstances of incident

General features of the applications

• the installation doesn’t need to break up the pavement

• the system is adatable to existing infrastructure along the road

it can be mounted on existing poles

universal adapter, fixing with steel ribbon

algorithms for compensation of vibration

• architecture based on distributed intelligence

the results of preprocessing can be transmitted with use of relatively narrow band width
