8. An application method of a bridge inspection device of BIM associated VR and unmanned aerial vehicle is characterized in that:
the method comprises the following steps:
the method comprises the following steps: setting a flight route of the unmanned aerial vehicle through a computer, and then controlling the unmanned aerial vehicle to fly around the bridge;
step two: the information acquisition module acquires the whole condition and peripheral information of the bridge and the flight state data of the unmanned aerial vehicle through the long-focus lens and then transmits the data back to the computer;
step three: the computer determines a processing scheme for implementing the operation and maintenance of the bridge according to the appearance of the bridge and the overall situation around the bridge;
step four: the computer sets an inspection route of the unmanned aerial vehicle, the unmanned aerial vehicle shoots the dead zone, crack and other defect areas of the bridge, and the binocular camera can measure the size of the crack of the bridge, so that the crack can be conveniently maintained;
step five: after information acquisition of the unmanned aerial vehicle is completed, storing the image and the information in an information storage module, and then transmitting the image and the information to a computer;
step six: the computer makes a BIM three-dimensional model of the information acquired by the image identification module and displays the information through the VR display screen, one display half screen of the VR display screen is used for displaying the information acquired by the image acquisition module, and the other display half screen is used for displaying the model information designed by the BIM;
step seven: and then the computer carries out data analysis on the BIM three-dimensional model to predict the health state of the bridge, an operation and maintenance scheme for the bridge is formulated according to the health state of the bridge, and the computer stores analysis comparison data, so that the staff can conveniently and rapidly maintain the bridge.
