A METHOD FOR TRACKING OF PLANAR MOVEMENT OF MULTIPLE OBJECTS

摘要

ABSTRACT A novel method is disclosed for tracking the motion of multiple objects using special marker geometries. The marker geometry is such that the segmented marker region can be automatically recognized with less computational effort than conventional pattern matching approaches and with greater robustness. The marker geometry allows determination of the orientation from a single marker thereby eliminating the need for using an additional marker merely for determining orientation. The method is made more reliable by use of a identification tag as part of the marker that positively identifies a marker from the rest of the markers and overcomes the difficulty encountered by many automatic tracking systems in re-establishing track after it is lost. r 8 ptc vm
