MEASURING METHOD USING MOVABLE TUNNEL DISPLACEMENT AND WORKING FACE VISUAL INFORMATION MEASURING SYSTEM

摘要

A measuring device using a system of measuring moving tunnel displacement and image information of a blind end plane is provided to maintain consistency of displacement measurement result irrespective of the knowledge and experience of an operator to secure specialty and reliability of a work. A system of measuring moving tunnel displacement and image information of a blind end plane includes a plurality of code targets(11) attached to a blind end plane of a tunnel, a point cloud generator(100) for generating point cloud on the blind end plane, a digital camera(200) for capturing the point cloud and image data of the code targets, a total station(300) for measuring three-dimensional absolute coordinates of the code targets, a computer(400) in which software generating a three-dimensional image using the image data and the three-dimensional absolute coordinates is installed, and a moving vehicle(500) in which the point cloud generator, the computer and the total station are mounted.
