Problems solved by technology
The inspection that used to take a whole day can be completed within a few hours by using drones for shooting, which greatly reduces the time-consuming inspection of lightning damage. With the permission of many parties from other management departments, general drone inspections are prohibited in China, so this method is only applicable to the inspection of aircraft parked indoors. It is not suitable for most aircraft temporarily parked on the airport apron after being struck by lightning. Be applicable

Embodiment Construction
[0023] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] like Figure 1 to Figure 6 As shown, the vehicle for inspecting the lightning strike condition on the outer surface of an aircraft based on machine vision in an outdoor environment provided by the present invention includes a mobile vehicle 1 that provides a moving effect, a horizontal movement mechanism 2 that is used to move horizontally when shooting, and is used to realize vertical movement when shooting. Vertical telescopic mechanism 3 for moving in the vertical direction and bearing the total weight of each mechanism, horizontal rotation mechanism 4 for realizing horizontal rotation during shooting, telescopic rocker mechanism for increasing shooting range and adjusting shooting angle 5, inspection plane The shooting system 6 and the driving control room 7 of the lightning strike damage condition on the outer surface; wh...

The invention discloses a machine vision-based airplane outer surface lightning stroke condition inspection vehicle in an outdoor environment. The vehicle comprises a moving vehicle, a horizontal moving mechanism, a vertical telescopic mechanism, a horizontal rotating mechanism, a telescopic rocker arm mechanism, a shooting system and a driving control room, the vehicle has the advantages that: under the combined action of the horizontal moving mechanism, the vertical telescopic mechanism, the telescopic rocker arm mechanism and the camera mounting frame, six-degree-of-freedom movement in a space can be realized, i.e., the change of the camera at any position and any posture in the space is realized, and the shooting area can completely cover an area to be inspected; and the situation thata certain lightning stroke area is not checked is avoided. Operation control of all mechanisms on the inspection vehicle is achieved through instructions of operators in the driving control room, manual errors caused by manual operation are avoided, and the defects that an existing inspection mode is long in time, large in number of the operators, high in labor intensity and the like are overcome. The inspection vehicle is convenient to move, conforms to regulations and is higher in safety.
Description
technical field [0001] The invention belongs to the technical field of airport ground special equipment, and in particular relates to a machine vision-based inspection vehicle for lightning strikes on the outer surface of an aircraft (including the upper surface of the wing, the upper surface of the horizontal stabilizer, and the upper end of the vertical stabilizer) in an outdoor environment. Background technique [0002] Aircraft are at risk of being struck by lightning during flight. Mild lightning strikes can cause the metal on the outer surface of the aircraft to burn, melt or show signs of metal deformation. High-intensity lightning strikes can cause holes to appear on the outer surface of the aircraft. The lightning strike point on the aircraft surface is usually an entry point and an exit point; the high probability areas of lightning strikes are: wing leading edge, wing trailing edge, wingtip, engine, vertical tail tip, horizontal stabilizer tip, elevator, nose radar...
