DEVICE FOR TRACKING POSITION BASED ON OPTICAL POSITION TRACKING SYSTEM AND METHOD THEREOF

摘要

According to an embodiment of the present invention, provided is a device for tracking a position which comprises: a camera calibration unit calculating a projection matrix with regard to a plurality of cameras based on an internal variable and an external variable of the plurality of cameras; a coordinate conversion unit converting a plurality of two-dimensional marker coordinates of an input image photographed from the plurality of cameras into a plurality of three-dimensional market coordinates based on the projection matrix; a rigid body classification unit grouping the marker coordinates having an Euclid distance included in a predetermined range among the plurality of three-dimensional marker coordinates to be classified into a plurality of rigid body groups; a trajectory calculation unit calculating a movement trajectory of the plurality of rigid groups based on a center coordinate for each of the plurality of rigid body groups; and an alarm unit transmitting an alarm by determining whether a collision or detachment between the plurality of rigid body groups is performed based on the movement trajectory.;COPYRIGHT KIPO 2020
