Moving object locating device, moving object locating method, and computer product

摘要

Camera installation flexibility on a moving object can be increased and accuracy in identifying the moving object improved by identifying a moving object origin trajectory as a potential position at which the moving object origin exists under the following conditions: 1) A distance between the moving object origin position and a reference virtual camera is constant. 2) A direction of virtual camera VCij as viewed from the moving object coordinate system (moving object origin O_m) is constant (angle formed by two lines that direct to marker P_j and to the moving object origin position C_ij as viewed from the virtual camera VCij is constant.) 3) Virtual camera VCij exists on marker circle (angle between markers P_i and P_j as viewed from virtual camera VCij is constant). It is possible to identify the position of moving object M by calculating the intersecting point of each moving object origin trajectory T upon multiple trajectories of moving object origin existing.
