Abstract
A remote control system and a remote control apparatus allow a human operator to remotely control a mobile body easily even if the system uses a low-speed communications link. The remote control system includes a remote control apparatus, in which a CPU selects old information based on both old information and the latest mobile body information from a mobile body, and determines a virtual view point V. The CPU generates a three-dimensional environmental image K and the virtual view point V based on the selected old information, and also generates a mobile body model M, a reference point B and a clipping center point based on the latest mobile body information and data regarding a mobile body model M, in a global coordinate system GC. The CPU calculates an angle of view based on a distance d between the virtual viewpoint V and the reference point B, makes a perspective projection of the three-dimensional environmental image K and the mobile body model M from the virtual view point V toward the clipping center point to obtain a projected image, makes a clip from the projected image based on the angle of view thereby making a composite image, and converts the composite image into a di…
