水中位置計測装置
Document Type and Number:
Japanese Patent JP6407814
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an underwater position measurement device easily performing the positioning of a measurement pole.SOLUTION: A underwater position measurement device includes: a measurement pole 11 having an abutting part abutting against a rubble mound on the lower part; an inclinometer 16 for detecting an incline angle of the measurement pole 11; a reference GPS receiver 27 installed at a known point; and observation GPS antennas 25, 25L, and 25R of the observation GPS receivers 27, 27A installed on the measurement pole 11 and also display means 33 having a separate body from the measurement pole 11. The display means 33 is provided with a plane position display part for displaying a position of a target point and a position of the abutting part of the present measurement pole 11 in coordinate; and an incline display part for showing an incline angle of the measurement pole 11 in coordinate. The visual check of the plane position display part in coordinate allows the abutting part of the measurement pole 11, the target point, and the distance to be intuitively determined, and this makes it possible to easily and quickly perform positioning work and to eliminate an error in human determination.SELECTED DRAWING: Figure 4
