UAV route correction system and correction method for hybrid rice pollination

Abstract

The invention discloses a UAV (unmanned aerial vehicle) route correction system for hybrid rice pollination and a correction method thereof. The UAV route correction system for the hybrid rice pollination is characterized in that the system comprises a UAV and a ground control station, wherein the UAV is a multi-rotor UAV; an embedded board based on Jetson TX2, a flight control module, a first wireless communication module, an image acquisition module and a satellite positioning device are arranged on the UAV, wherein the flight control module is used for receiving, decoding and executing control commands from the Jetson TX2 to control UAV operations; the ground control station comprises a UAV ground control station software computer board and a second wireless communication module; the Jetson TX2 is in wireless communication connection with the ground control station through the first wireless communication module and the second wireless communication module. The UAV route correctionsystem for the hybrid rice pollination and the correction method thereof have the advantages of adjusting forward direction and position of the UAV in real time by adopting a full convolutional neuralnetwork model to segment a rice paternal line to calculate the yaw angle and the distance from the center line of the rice paternal line, ensuring the UAV to fly smoothly over the rice paternal line,and improving the effect of the hybrid rice pollination.

Description

technical field [0001] The invention relates to the field of UAV remote sensing technology, in particular to a UAV route correction system and a correction method for hybrid rice pollination. Background technique [0002] Rice not only has a short flowering period, but the normal rice population has a full flowering period of 7 to 10 days, and the flowering time is only 1.5 to 2 hours per day during the flowering period, and the pollen life is very short, only 4 to 5 minutes, so pollination must be completed within a limited time. The current pollination methods mainly rely on artificial assisted pollination and mechanical methods. Manually use rope vibration or bamboo pole vibration to push the male parent ear layer to scatter pollen to the female parent box. However, these methods are likely to cause uneven distribution of pollen in the field. The utilization rate is low, the pollination speed is slow, and it takes a lot of work. The mechanical pilot uses the downflow air...

The current pollination methods mainly rely on artificial assisted pollination and mechanical methods. Manually use rope vibration or bamboo pole vibration to push the male parent ear layer to scatter pollen to the female parent box. However, these methods are likely to cause uneven distribution of pollen in the field. The utilization rate is low, the pollination speed is slow, and it takes a lot of labor

The mechanical pilot uses the downflow air pressure of the UAV rotor to perform pneumatic pollination. Although the mechanical pollination improves the pollination effect, the pilot is limited by the line of sight and cannot accurately control the altitude and position of the route.
