APPARATUS AND METHOD FOR STABILITY ESTIMATION A STRUCTURE USING MOTION CAPTURE METHOD

摘要

The present invention relates to an apparatus and a method for evaluating stability of a structure using motion capture, including a step in which a plurality of markers, which are distributed on a continuous beam structure, are imaged with a plurality of cameras so that three-dimensional coordinate values of the markers are obtained; a step in which coefficients of a plurality of candidate shape functions of different orders are respectively determined through regression analysis based on the three-dimensional coordinate values and property values that are boundary conditions of the structure; a step in which the candidate shape function with the minimum error with respect to the three-dimensional coordinate values is selected as the shape function of the structure among the plurality of candidate shape functions of the different orders in which the respective coefficients are determined; a step in which an estimated stress is calculated by differentiating the shape function so that safety of the structure can be evaluated through comparison to the allowable stress of the structure.
