Design of Digital Aerial Photography System for UAV based on Wireless
Sensor Network
Abstract
The traditional UAV aerial photography system has the disadvantages of
unclear imaging, low system efficiency and poor flight control effect.
Thus, a digital aerial photography system based on wireless sensor
network is proposed. Firstly, the principle of aerial photography system
is analyzed, and the wireless sensor network is set up. A large number
of wireless sensor nodes are deployed in the interval, and functions
such as wireless communication and calculation are completed by nodes;
the SN-RN data acquisition layer, the RN-UAV relay transmission layer
and the UAV-DC mobile aggregation layer are designed to form a wireless
sensor network architecture, and the UAV digital aerial photography
technology is combined to form the wireless sensor network. Experiments
show that the medium error, maximum error and medium error limit of the
digital aerial photography of the UAV are low, the total working time of
the system is short, and the accuracy of the flight execution of the UAV
is maintained between 93%-95%, and always stable. Therefore, the
overall imaging effect of this method is better, the system work
efficiency is higher, the system control effect is better, and it is
more practical and advantageous.
