Abstract

The invention provides an information transmission method of an unmanned aerial vehicle cluster in visual navigation. The method comprises the following steps of: creating a communication ID of each unmanned aerial vehicle of the unmanned aerial vehicle cluster, so as to establish an unmanned aerial vehicle collaborating group to carry out visual navigation; dividing a scene to be collected according to a transmission task in the unmanned aerial vehicle collaborating group, so as to obtain a first image area and a second image area, and calculating the size of the second image area to be usedas parameters of the second image area; the unmanned aerial vehicle of a sender collects the first and the second image areas in different scales according to the division result; the unmanned aerialvehicle of the sender sets the collected first and second image areas and transmission priorities and classes of parameters; the unmanned aerial vehicle of a receiver receives the first and the second image areas and parameters sequentially according to the transmission priorities, and analyzes the first and the second image areas and parameters according to the classes so as to reconfigure sceneinformation. The embodiment of the invention has the advantages of small data transmission quantity and strong real-time data transmission and can effectively avoid transmission blocking.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle communication, in particular to a method for transmitting unmanned aerial vehicle cluster information in visual navigation. Background technique [0002] In recent years, computer vision methods have become an important method in the research of UAV visual navigation due to their characteristics of economy, passiveness, simple equipment, and large amount of information. UAV visual navigation is a new navigation method that organically combines comprehensive vision, flight, air traffic control and communication technologies. It usually means that UAVs can use only airborne sensors without using other auxiliary equipment (such as GPS) information. (Such as: visual sensor, inertial navigation system, speed sensor, radar altimeter, etc.) for navigation, reducing the dependence on external equipment and environment when the UAV is flying and landing, so that the UAV has higher autonomy ...
