1A1-B10 Measuring of structure's shape by 3D measurement mobile unit : Realization of the real-time comparison and an application to the road tunnel construction(Robotics and Mechatronics in Construction and Demolition)

Abstract

An experiment for 3D measurement was tried in a road-tunnel under construction by "three-dimensional measurement mobile unit" that was produced experimentally, this time. This system has two modes for measurement. One is the measurement mode when the speed is required; the other is a measurement mode when the accuracy is required. Measurement experiments by each mode were tried, and the results were considered. In addition, the demonstration about the real-time display was performed. And, an assessment of differences from design data in calculation results was made.
