Visual fusion and obstacle display control method and device based on anti-collision radar

The invention discloses a control method and device based on anti-collision radar visual fusion and obstacle display, and the method comprises the steps: enabling an airplane to carry a radar and navigation equipment, and obtaining the obstacle target information and three-dimensional terrain information under a radar coordinate system through the radar; synchronously acquiring current spatial position information of the aircraft and navigation equipment state feedback information under the radar coordinate system through the navigation equipment; the method comprises the following steps: uniformly converting obstacle target information and three-dimensional terrain information under a radar coordinate system into a uniform coordinate system through current aircraft space position information acquired by navigation equipment; and judging whether the current navigation equipment data is effective or not according to the navigation equipment state feedback information to obtain new three-dimensional topographic
