METHOD FOR AUTOMATIC REGISTRATION OF 3-DIMENSIONAL SCAN DATA FOR INTELLIGENT EXCAVATION SYSTEM

摘要

An automatic matching method of three-dimensional scan data for an intelligent excavation system is provided. An automatic matching method of 3D scan data for an intelligent excavation system includes the steps of: a) installing a spherical GPS combined target at a target point; b) collecting a plurality of scan data by performing a three-dimensional scanning operation using a three-dimensional scanner at a target point where a spherical GPS combined target is installed; c) automatically recognizing the spherical GPS combined target and performing automatic registration of a plurality of scan data using the spherical GPS combined target as a reference point; d) converting GPS coordinate values of the spherical GPS combined target into a common coordinate system; And e) reconstructing and merging the automatically matched plurality of scan data into a single data format, wherein the spherical GPS combined target is changed even if the position or orientation of the 3D scanner is changed by using the spherical GPS combined target. It is always characterized by the recognition of the same type of target.
