Flight guiding method based on comprehensive scene

The invention relates to a flight guiding method based on comprehensive vision. The method comprises the following steps: firstly, matching a multi-source detection image, attitude data and landscape data of a helicopter to generate a three-dimensional geographical environment, carrying out real-time calculation by combining a flight path point and a flight route of the helicopter, extracting a comprehensive visual range and carrying out information simulation, then carrying out comprehensive processing on a terrain database and multi-source avionics data, and finally, carrying out real-time calculation. According to the method, terrain and obstacle warning prompts are generated and superposed in the scene to be displayed, and clear and easily understood scene image output and reliable flight indication information are provided by recognizing threats such as short-distance terrain obstacles and the like and long-distance terrain conflicts in the near-earth and landing stages. The method has the advantages of
