SURVEY METHOD AND SURVEY DEVICE FOR UNEVEN PLANE

摘要

PROBLEM TO BE SOLVED: To easily and accurately survey an uneven plane of a road, etc., without implementing traffic regulations.;SOLUTION: A slave machine 10 is constituted by fitting a 360° prism 7 on a base 1 which is movable by providing two wheels 5 to an axle 4, and a center 8 of the prism 7 is located right above the axle 4. A master machine is configured to acquire position information on the center 8 of the prism 7 of the slave machine 10 by tracking the center, emitting a laser beam to the center 8 of the prism 7, and receiving its reflected laser beam. The master machine 20 is placed at a reference point P, and the slave machine 10 is run along a measurement line S crossing the road, so that the plane position and height of the slave machine 10 can be acquired in the form of coordinates (X, Y, Z) by receiving the laser beam. Coordinate positions (X, Y, Z) is obtained at many measurement points along the measurement line to survey a section (the plane position and height) along the measurement line S.;COPYRIGHT: (C)2013,JPO&INPIT
