Description

Unmanned aerial vehicle is patrolled and examined to outer facade defect of building based on AI vision and infrared thermal imaging Technical Field The invention relates to the technical field of building engineering detection and unmanned aerial vehicle intelligent inspection, in particular to an unmanned aerial vehicle for inspecting defects of an outer facade of a building based on AI vision and infrared thermal imaging. Background The outer facade of the building is exposed in complex environments such as rainwater, wind power, temperature change and the like for a long time, various defects such as cracks, hollows, leakage, falling off of a heat preservation layer and the like are easy to generate, the defects not only affect the attractiveness and durability of the building, but also cause the problems of falling off of materials, potential structural hazards and the like, and serious threat is formed to public safety, so that the regular development of accurate inspection is a key link of operation and maintenance of the building. The traditional inspection mainly relies on modes such as manual visual inspection, hammering method, field drawing test and the like, is low in efficiency and high in cost, and seriously depends on experience of inspection staff, so that error detection and inspection are easy to occur, meanwhile, a hanging basket or a scaffold is required to be erected in high-altitude operation, the safety risk is extremely high, and inspection requirements of modern buildings, particularly super high-rise buildings, are difficult to meet. Along with the technical development, unmanned aerial vehicle is applied to the outer facade inspection of building gradually, has solved the safety and the efficiency problem that artifical inspection to a certain extent, but prior art still has obvious limitation. The unmanned aerial vehicle is characterized in that a part of unmanned aerial vehicle is only provided with a single detection device, dominant and recessive defects are difficult to identify at the same time, gesture offset is easy to occur when the unmanned aerial vehicle is in face of air flow interference, shooting precision is affected, equipment shaking can be caused by rebound of downwash air flow of a rotor wing during close-range operation, and the cradle head has insufficient gesture adjustment flexibility and cannot be adapted to a complex elevation structure. In addition, the existing equipment lacks an adaptive design and emergency protection mechanism for severe environments, the risks of data loss and equipment damage are high, and the stability and reliability of inspection are restricted. Chinese patent network publication No. CN120171779B discloses an unmanned aerial vehicle survey device of steel construction building, be connected with spring power coil through the electricity between swivel mount group and the fine electromagnetic socket group, make unmanned aerial vehicle survey device's survey operation can adapt to various wind-force weather, promote survey effect, but rely on complicated flight control algorithm to realize the self-balancing, publication No. CN112429230a discloses a construction machinery to use equipment of patrolling and examining, adopt shock attenuation bearing structure's torsional spring to promote the bracing piece downwards, the bracing piece drives the support pole and rotates downwards, the torsional spring makes things convenient for the bracing piece to carry out the support of different angles, protect equipment of patrolling and examining, but when facing the organism out of control, there is not emergent protection mechanism, easily cause data loss, publication No. CN112550711B discloses an unmanned aerial vehicle and system of building outer wall inspection, adopt the structural design of mount, be convenient for carry wall body check equipment, make wall body check equipment can be more close to the measured wall, the detected data that wall body check equipment obtained is more accurate, but the problem that the rotor down wash down bounce can lead to equipment to rocking when working closely can not be solved. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an unmanned aerial vehicle for inspecting defects of an outer facade of a building based on AI vision and infrared thermal imaging, which solves the problems that the traditional manual inspection is low in danger and efficiency, the traditional unmanned aerial vehicle is easy to be interfered by air flow, the defect identification is incomplete, the short-distance shooting is unstable, the inspection data is easy to be lost when the unmanned aerial vehicle falls aloft, and the like. The technical scheme is that the unmanned aerial vehicle for inspecting defects of the outer facade of a building based on AI vision and infrared thermal imaging comprises an unmanned aerial vehicle, wherein a lower control box is fixedly arranged at the bot
