An Evaluation and Localization System of The Concrete Soundness Based on Mixed Reality through Real-Time Strike Sound Analysis and It's Method

摘要

The present invention relates to a mixed reality-based concrete internal cavity evaluation and location recognition system and a method through real-time hitting sound analysis, and more particularly, to a hitting device that generates a hitting sound by the concrete internal cavity evaluation and location recognition system, and the hitting sound It consists of a microphone that collects, a communication unit that transmits sound data in real time, and smart glasses that analyze the sound data in real time to find the internal cavity of the concrete and analyze the soundness, and track the location of the striking equipment with the camera as an image, By tracking the striking equipment in real time, the location of the internal cavity can be recorded and displayed directly on the target location with smart glasses. , By installing a unidirectional microphone adjacent to the striking head of the striking equipment, ambient noise can be removed, and by manufacturing and mounting the striking head of the striking equipment in the form of a polygonal striking body, the surface of a concrete structure or a specific member is rotated By transmitting the striking sound collected from the unidirectional microphone to smart glasses wirelessly or wired, and performing FFT (fast fourier transform) analysis on the smart glasses in real time for the transmitted striking sound, by classifying the soundness, By detecting the internal cavity of a concrete structure, it is possible to check the damage state of the structure, and when using smart glasses to measure the position of the concrete internal cavity and check the damage state, it is more objective than the conventional inspection hammer. and it works quickly.
