Method and device for cooperative surveying and mapping of surveying and mapping unmanned aerial vehicle group

Abstract

The invention discloses a method and device for cooperative surveying and mapping of a surveying and mapping unmanned aerial vehicle group, and belongs to the technical field of surveying and mapping. The device comprises a vehicle body, a driving part is fixedly connected to the bottom end of the vehicle body, a surveying and mapping part is installed at the bottom end of the driving part, and a camera and an infrared induction probe are installed on the surveying and mapping part; the bottom end of the driving part is provided with a first limiting ring and a second limiting ring, the surveying and mapping part is fixedly connected with a lantern ring, the lantern ring is rotationally connected with the driving part through the first limiting ring, and the outer surface, located in the second limiting ring, of the surveying and mapping part is fixedly sleeved with a first magnet; by arranging the first limiting ring and the second limiting ring at the bottom end of the driving part, double limiting of the surveying and mapping part is achieved through the arrangement of the first limiting ring and the second limiting ring, so that the stability of the surveying and mapping part in the rotating process is improved, and the problems that in the prior art, in the rotating process, the surveying and mapping part easily shakes, and the surveying and mapping part cannot rotate are solved. And a large error of surveying and mapping is caused.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a method and device for collaborative surveying and mapping of a surveying and mapping UAV group. Background technique [0002] When UAVs are used for surveying and mapping, they can not only truly reflect the situation of ground objects, obtain object texture information with high precision, but also generate real 3D city models through advanced positioning, fusion, modeling and other technologies to meet the needs of my country's current The requirements of urban informatization construction. [0003] In the prior art, the patent whose application number is CN202010229461.1 specifically relates to a surveying and mapping unmanned aerial vehicle, including an unmanned aerial vehicle body, an installation box, a protective cover, a camera and an installation mechanism are arranged under the unmanned aerial vehicle body, and the camera is fixed On the installation me...

[0003] In the prior art, the patent whose application number is CN202010229461.1 specifically relates to a surveying and mapping unmanned aerial vehicle, including an unmanned aerial vehicle body, an installation box, a protective cover, a camera and an installation mechanism are arranged under the unmanned aerial vehicle body, and the camera is fixed On the installation mechanism and extend into the protective cover; there are multiple piston rods above the protective cover, and a support frame is connected to the lower part of the protective cover; the first piston cylinder and the second piston cylinder are arranged in the installation box, and the first piston cylinder slides A first piston is connected, and a second piston is slidably connected in the second piston barrel; the first piston barrel and the second piston barrel are filled with a transmission medium between the first piston and the second piston; the upper end of the piston rod is connected to the On the first piston; the second piston is connected with a connecting rod, and the connecting rod is provided with a wiper strip. Although the use of the above-mentioned patent can effectively solve the problem that the camera is exposed, the lens is easily covered with dust, and when the drone lands, the drone is damaged. The impulsive force is large, which is easy to cause the loss of the camera. However, when the drone is used for collaborative surveying and mapping, the surveying and mapping parts are prone to instability during the rotation process, which leads to the disadvantages of errors in the surveying and mapping. For this reason , a method and device for collaborative surveying and mapping of surveying and mapping UAV swarms are proposed
