The embodiment of the invention provides a grid-based low-altitude flight collision early warning method and device, equipment and a medium, and is applied to the technical field of flight path planning. The method comprises the following steps: acquiring flight information of a current flight target, wherein the flight information comprises flight time information and flight path information; selecting a corresponding flight path point according to the flight time information and the flight path information; predicting the next flight position of the current flight target according to the flight track point; determining a 3D grid corresponding to the next flight position; and performing collision early warning in response to existence of other flying targets in the 3D grid. In this way, the distance can be calculated in advance, the flight path can be predicted, the follow-up flight path can be planned and decided, air accidents are effectively avoided, the problem that the prediction result is overtime due
