The invention aims to assist professional engineering personnel to quickly measure and judge a crack in a structure. The unmanned aerial vehicle device comprises four parts, namely, an unmanned aerial vehicle, a function modulegroup, a ground control station and a ground data processing center; the unmanned aerial vehicle includes an unmanned aerial vehicle frame, a power system, a data interface, and a coprocessor; the function module group includes an image acquisition module, an ultrasonic ranging module, a laser transmitting module and a data transmission module; the ground control station includes a remote controller, a display screen and a signal amplification module; and the ground data processing center can obtain the size data of the crack from captured images. According to the unmanned aerial vehicle device of the invention, the images taken by the unmanned aerial vehicle are ingeniously utilized; and the principle of photo digital imaging is utilized, errors are decreased through a laser reference object, and therefore, the measurement of the length and width of the crack of a structural component is realized, staff can quickly judge the health status of a house, and provide the preliminary identification conclusion of the structure of the house. The unmanned aerial vehicle device has the advantages of simple operation, high data processing speed and high data reliability.
Description
technical field [0001] The invention relates to an unmanned aerial vehicle for calculating the size of cracks from photos, in particular to an unmanned aerial vehicle for measuring the size of cracks in concrete structures. Background technique [0002] During the normal use of modern buildings or after experiencing natural disasters such as earthquakes, due to the building materials themselves and the influence of external loads, the structure will produce deformation, uneven settlement, severe damage and other adverse phenomena, resulting in structural instability or loss of bearing capacity. Although most of the building structures in actual engineering work with cracks, when the crack width exceeds the threshold, it not only affects the appearance of the building, but also gives users a sense of danger, and seriously affects the bearing capacity and durability of components. [0003] When evaluating the durability of a building, one of the important indicators is the cra...
