Abstract
The invention relates to an unmanned aerial vehicle monitoring visual field control method and device based on a fisheye lens and a program product, relates to the field of agricultural vegetation protection, and solves the problems of low reliability and durability and high cost caused by the adoption of a traditional mechanical holder by an agricultural plant protection unmanned aerial vehicle. The method comprises the following steps: shooting a surrounding environment by using a fisheye lens to obtain a fisheye image with a first resolution; receiving a visual angle control instruction sent by the unmanned aerial vehicle ground station; converting the visual angle control instruction into a vertical pixel offset and a horizontal pixel offset of a cutting window of the fisheye image; intercepting a target image with a second resolution from the fisheye image according to the vertical pixel offset and the horizontal pixel offset of the cutting window, wherein the second resolution is smaller than the first resolution; and coding and compressing the target image to form a video stream, and sending the video stream to an unmanned aerial vehicle ground station.
