This approach is based on a hybrid tracking system for laboratory experiments with pedestrians in dense crowds consisting of cameras and IMUs. A camera system on the ceiling forms the basic detection and tracking system. Current experiments with heterogeneous crowds have arisen new requirements to this system. Participating wheelchair users tend to get occluded by surrounding people which leads to incomplete trajectories. To fill those temporary gaps the data of IMUs that are attached to the wheelchairs are used. The IMU trajectories are calculated with an Inertial Navigation System (INS) algorithm. The orientation is calculated with a sensor fusion filter and the distance is estimated by numerical integration of the acceleration measurements. To limit the drift the calculated velocity of the wheelchair is restricted to the velocity of the pushing person. Preliminary studies were performed to investigate this approach and resulting trajectories are presented. 000842815 536__ $$0G:(DE-HGF)POF3-511$$a511 - Computational Science and Mathematical Methods (POF3-511)$$cPOF3-511$$fPOF III$$x0 000842815 536__ $$0G:(DE-Juel1)PHD-NO-GRANT-20170405$$aPhD no Grant - Doktorand ohne besondere Förderung (PHD-NO-GRANT-20170405)$$cPHD-NO-GRANT-20170405$$x1 000842815 7001_ $$0P:(DE-Juel1)132064$$aBoltes, Maik$$b1$$ufzj 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.pdf$$yOpenAccess 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.gif?subformat=icon$$xicon$$yOpenAccess 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000842815 8564_ $$uhttps://juser.fz-juelich.de/record/842815/files/217.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000842815 909CO $$ooai:juser.fz-juelich.de:842815$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000842815 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)142414$$aForschungszentrum Jülich$$b0$$kFZJ 000842815 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132064$$aForschungszentrum Jülich$$b1$$kFZJ 000842815 9131_ $$0G:(DE-HGF)POF3-511$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data$$vComputational Science and Mathematical Methods$$x0 000842815 9141_ $$y2017 000842815 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000842815 920__ $$lyes 000842815 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 000842815 980__ $$acontrib 000842815 980__ $$aVDB 000842815 980__ $$aUNRESTRICTED 000842815 980__ $$aI:(DE-Juel1)JSC-20090406 000842815 9801_ $$aFullTexts
