Title:
METHOD FOR ESTIMATING POSITION OF PRECAST COMPONENTS AND POSITION ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/212472
Kind Code:
A1
Abstract:
A method for estimating a position of a precast concrete bottom plate comprises the steps of: acquiring scan data related to shapes and dimensions of precast girders to be coupled with precast concrete bottom plates by using a three-dimensional laser scanner; filtering noise data from the scan data by performing a data preprocessing process on the scan data so as to extract first scan data therefrom; extracting, from the first scan data, shear connector data related to shear connectors formed at each of the precast girders; extracting head data related to each of heads of the shear connectors on the basis of the shear connector data; estimating a position of each of the shear connectors on the basis of the head data; and estimating an optimum position of each of the precast concrete bottom plates to be coupled with the shear connectors by using the position of each of shear connectors and the shape information on the precast concrete bottom plates.
