A construction safety inspection method based on vision using small unmanned aerial vehicles

摘要

A vision-based structural stability inspection method using a small unmanned aerial vehicle according to the present invention is characterized in that a structure is photographed in a small unmanned aerial vehicle operated by a remote control of a user and the stability of the structure The method comprising the steps of: a) acquiring an image of a structure through a camera mounted on a small unmanned aerial vehicle, b) compressing and wirelessly transmitting the acquired image, c) D) a pre-processing step of converting the received color image into a monochrome image; e) detecting a contour line of the monochrome image through the preprocessing step using a cannier edge detection method; f And outputting the image having the contour detected to the display unit to detect whether the user has cracked or not .;
