Flight route planning method and system and computer storage medium

The invention discloses a flight route planning method and system and a computer storage medium. The method comprises the following steps: acquiring digital elevation data and flight influence factor data of a task area; classifying the terrains of the task areas to obtain corresponding terrains; converting the terrain into a corresponding terrain grid; setting influence values in the terrain grids to form a terrain influence matrix; converting the flight influence factor data into a flight influence grid; influence values are set in the flight influence grids, and a flight influence matrix is formed; superposing the terrain influence matrix and the flight influence matrix to form a fusion matrix; all the grids are traversed in the fusion matrix in sequence, so that the sum of influence values of the grids on the path between the starting point and the ending point is minimum. According to the method, the influence of the route on the whole can be ensured to be minimum, the operation efficiency of the method
