UAV image monitoring and transmission method

Abstract

The invention discloses an image monitoring and transmitting method for an unmanned plane. The method comprises the steps as follows: S1, a monitoring computer starts a flight control program, and a satellite navigation unit starts a GPS navigation program; S2, a high-definition action camera collects a video image according to a track of the flight control program, and a vision computer processes the image; S3, a video image wireless transmitting module and a video image receiving module combine to finish the wireless transmitting and receiving of an image signal; S4, a central site image processing module processes the received image signal and displays the image signal on a display terminal. The method of the invention supports visual navigation, image recognition and obstacle avoidance, and fuses a satellite communication network mode and a traditional communication mode so as to achieve the high-speed exchange of large-capacity image data. The method of the invention has relative high safety.

Description

technical field [0001] The invention relates to the field of image monitoring and transmission, in particular to a UAV image monitoring and transmission method. Background technique [0002] At present, the videos taken by drones are generally transmitted to the ground station system through image transmission equipment, and then observers can view the videos taken by drones in real time on the ground base station, but due to the limitations of image transmission equipment and antennas , so that the distance between the location of the ground base station and the UAV must be within a certain range, so that the observer must follow the ground base station within this range, and if it leaves this range, the UAV cannot be viewed in real time The captured video has very large restrictions on its application. [0003] The return of existing video images is mostly based on analog video signals, the images are not clear, and a device called IOSD is needed. This device actually sup...

Problems solved by technology

However, the cost of these two technologies remains high, and their expensive initial construction costs and communication costs are often prohibitive and cannot be widely promoted.

[0006] WIMAX / WIFI and other technologies to build a wireless metropolitan area network for wide-area coverage video applications require the builder to build a large number of base stations. Due to the huge initial construction cost of the domain network, it is unwilling to share it with other users, thus causing a great waste of social resources
