Unmanned aerial vehicle variable-angle crown profiling variable spraying system and method

The invention discloses an unmanned aerial vehicle variable-angle crown profiling variable spraying system and method. The system comprises an image acquisition module, a main control module arranged in an unmanned aerial vehicle, a first execution unit and a second execution unit, wherein the first execution unit and the second execution unit are arranged in bilateral symmetry with the main control module; the main control module is electrically connected with the image acquisition module, the first execution unit and the second execution unit, and the execution units analyze the tree crown images acquired by the image acquisition module according to the main control module and realize dynamic spraying on different tree crowns according to the characteristics of the tree crowns. The contour and distance of the tree form are obtained through image processing, the optimal spraying angle and spraying amount are calculated based on the flight speed, then profiling and variable spraying are achieved, the uniformi
