JUDGMENT SYSTEM FOR DOT GROUP WITHIN CONSTRUCTION LIMIT USING LASER DOT GROUP, JUDGMENT METHOD FOR DOT GROUP WITHIN CONSTRUCTION LIMIT USING LASER DOT GROUP, AND JUDGMENT PROGRAM FOR DOT GROUP WITHIN CONSTRUCTION LIMIT USING LASER DOT GROUP

摘要

PROBLEM TO BE SOLVED: To provide a judgment system for dot groups within a construction limit using laser dot groups which can easily detect an obstacle feature against a construction limit area with high precision in a short time regardless of a rail section linearity.;SOLUTION: A parameter memory 101, a laser dot group database 103, a track center related information calculating unit 110, a track center related information memory 115, a curve radius calculating unit 130, a curve radius memory 135, a dot group extraction range setting unit 140, a three-dimensional memory 145, a laser dot group acquisition unit 150, a two-dimensionalizing unit 170, a two-dimensional plane memory 175, a feature object judgment unit 180, and a judgment result memory 185 are provided to incline a construction limit frame in accordance with cants of a curved part, and to enlarge a construction limit frame CFi indicating the frame of the construction limit in accordance with curve radius Ri.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
