AVITRACK Project FP6-502818 WP1 :Apron Activity Model
WP1 – Apron Activity Model • Task 1.3 : Formalism for Model Representation • Design of a language to describe AVITRACK scenarios corresponding to servicing operations (e.g. Unloading operation) • Design of the following formalisms : • Scene model of the apron (zones of interest, airport walls) • Parked vehicles (zones related to parked vehicles) • Expected objects in the scene (size of vehicles, aircraft and people) • Camera information and algorithms parameters • Task 1.4 : Models creation • Creation of the scenario models in collaboration with Silogic
WP1 – Apron Activity Model • Example of the Unloading Front Operation model CompositeEvent(UnLoading_Front_Operation, PhysicalObjects( (v1 : Vehicle), (v2 : Vehicle), (z1 : Zone), (z2 : Zone), (z3 :Zone)) Components( (c1 : CompositeEventLoader_Arrival(v1, z1, z2)) (c2 : CompositeEventTransporter_Arrival(v2, z1, z3)) Constraints( (v1->SubType = LOADER) (v2->SubType = TRANSPORTER) (z1->Name = ERA) (z2->Name = RF_DoorC_Access) (z3->Name = LOADER_BackZone) (c1 before c2)))
WP1 – Apron Activity Model • Illustration of Dynamic Context :
WP1 – Apron Activity Model • Delivered documents : • Formalism for Scene Model (IN_AVI_03_001) • Ontology (IN_AVI_01_020, with Silogic) • ORION Scenario Description Language (IN_AVI_03_002)
AVITRACK Project FP6-502818 WP3 : Scene Tracking Task 3.6 : Complex Scene Tracking
WP3 - Scene Tracking • Task 3.6 : Complex Scene Tracking • Objective : Improve Tracking in complex situations (lost of objects, occlusions, lack of contrast, reflections, shadows…) • Long-Term Tracking (LTT) • uses a temporal window (typically 10 to 20 frames) to explore possible tracks for each mobile object • uses specific algorithms for each type of mobile objects (vehicles, people, aircraft) • Global Tracking (GT) • global spatio-temporal analysis of mobile object trajectories using a rules based architecture
WP3 - Scene Tracking • Tracking of a vehicle partially detected Without Global-Tracker - With Global-Tracker
WP3 - Scene Tracking • Deliverables of two software : • Long-Term Tracking on Dec. 04 (first) and Jan. 06 (final) • Global Tracking on June 05 (first) and Jan. 06 (final)
AVITRACK Project FP6-502818 WP4 : Scene Understanding
WP4 - Scene Understanding • Objectives : • Development of a software to recognise any type of operations described by the Scenario Description Language (WP1) • Adaptation, recognition and evaluation of specified scenarios (AVITRACK operations) • Task 4.1 : Basic Event Recognition (e.g. stop of vehicle v) • Task 4.2 : Single Vehicle Movement Interpretation (e.g arrival of vehicle v) • Task 4.3 : Interaction Recognition • Task 4.4 : Complex Activity Recognition
WP4 - Scene Understanding • 61 Modelled and recognised scenarios • 21 general video events (Task 4.1) • 10 primitive states (e.g. person inside a zone) • 5 composite states (e.g. vehicle stopped in a zone) • 6 primitive events (e.g. vehicle changes zone) • 28 scenarios involving a single vehicle (Task 4.2, Task 4.3) • 8 scenarios for the GPU (Aircraft Arrival Preparation on 10 seq. ) • 8 scenarios for the Tanker (Refuelling operation on 7 seq. ) • 3 scenarios for the Aircraft (Aircraft Arrival on 2 seq.) • 3 scenarios for the Tow Tractor (Tow Tractor Arrival on 2 seq.) • 3 scenarios for the Conveyor (Conveyor Arrival on 2 seq.) • 3 scenarios for the Catering (Catering vehicle Arrival on 3 seq.)
WP4 - Scene Understanding • Modelled and recognised scenarios • 12 scenarios involving multiple vehicles (Task 4.3, Task 4.4) • 12 scenarios for the Loader and the Transporter • Unloading Front operation (global) recognised on 2 seq. • Unloading Front operation (detailed) recognised on 2 seq. • Other scenarios : detection of the handler, platform elevation…
WP4 - Scene Understanding • Example of the Unloading Front Operation (global) CompositeEvent(UnLoading_Front_Global_Operation, PhysicalObjects( (v1 : Vehicle), (v2 : Vehicle), (z1 : Zone), (z2 : Zone), (z3 :Zone)) Components( (c1 : CompositeEventLoader_Arrival(v1, z1, z2)) (c2 : CompositeEventTransporter_Arrival(v2, z1, z3)) Constraints( (v1->SubType = LOADER) (v2->SubType = TRANSPORTER) (z1->Name = ERA) (z2->Name = RF_DoorC_Access) (z3->Name = LOADER_BackZone) (c1 before c2)))
