Unmanned aerial vehicle image recognition method suitable for forest investigation

The invention relates to the technical field of avionics image recognition, in particular to an unmanned aerial vehicle image recognition method suitable for forest investigation, which comprises the following steps: firstly, carrying out image acquisition on a forest environment through a camera, producing image data, then preprocessing the image data, then carrying out image acquisition on the forest environment through an infrared detection head, and carrying out image recognition on the forest environment; the method comprises the steps of generating infrared probe data, then preprocessing the infrared probe data, then performing detection model training on the preprocessed image data and the infrared probe data, and finally transmitting abnormal points in the image data to a terminal through a wireless transmission module. Reconnaissance with a fixed route and fixed time is carried out in a fixed area in a forest, and when an abnormality is found, the wireless transmission module remotely contacts with m
