THREE-DIMENSIONAL MAP DISPLAY DEVICE EQUIPPED WITH THREE-DIMENSIONAL WALK-THROUGH DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional walk-through device capable of automatically determining all position, height, direction, and distance from a start point to an end point of a walk-through route by indicating arbitrary movement position and height on a three-dimensional display window.;SOLUTION: The three-dimensional map display device indicates geographic coordinates and height(altitude) by a pointing device 107 on a plan, and a height section or a height rotation figure of a three-dimensional spatial image. A position coordinate determining means 108 and a height information determining means 109 determine and provide the position coordinate and the height information of the point indicated from the three-dimensional map information to a movement information determining means 111, and the walk-through route from the start point to the end point is automatically generated as a scenario. There is no necessity of a conventional and problematic trial-and-error method for parameter information of the position, height, direction, and distance in a two-dimensional space at the time of generation of walk-through scenario information.;COPYRIGHT: (C)2005,JPO&NCIPI
