Title:
MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/240788
Kind Code:
A1
Abstract:
The present invention provides a measurement system for measuring the moving amount or position of a mobile body moving within a rectangular measurement area, the measurement system being equipped with a measurement instrument 12 that executes measurement processing for a predetermined purpose, and an orthogonal laser range finder 13 with a gimbal mechanism, the orthogonal laser range finder 13 using two orthogonal laser beams to measure respective distances to two objects, the measurement system including: a mobile body 1 of an omnidirectional mobile type that can move in any direction within the measurement area; a first reflector 2 disposed outside the measurement area and along one side of the measurement area, the first reflector 2 reflecting one of the two laser beams output from the orthogonal laser range finder 13; a second reflector 3 disposed outside the measurement area and orthogonally to the first reflector 2, the second reflector 3 reflecting the other of the two laser beams output from the orthogonal laser range finder 13; and a computer 4 that can communicate with the measurement instrument 12 and the orthogonal laser range finder 13.
