METHOD FOR DETECTING POSITION OF REBAR IN REINFORCED PRECAST CONCRETE AND DETECTING APPARATUS THE SAME

摘要

The reinforcing bar position detection method for precast concrete includes a step of irradiating a precast concrete with a laser beam to output scan data including color information and geometry information and extracting effective pixels from the scan data based on the geometry information and color information, Extracts the rebar scan data, which is data representing reinforcing rebars, from the valid scan data, divides the rebar scan data into a plurality of segments using a region growing method, Segments may be evaluated to select and output valid segments corresponding to each of the reinforcing bars, and then the position of each of the reinforcing bars may be calculated by comparing the valid segments with predetermined design models of the precast concrete.
