A method of determining route safety based on graphical logic AND operation

Abstract

With the increase of geographic information capacity, the calculation of flight path planning will increase rapidly. In this paper, we propose a method to determine the positional relationship between obstacle and flight path using graphical logic AND algorithms. By drawing the obstacle information map and the aircraft route map under the same reference, the intersection of geographic information and spatial region judgment is transformed into computer graphics logic AND operations, so that the real-time judgment of the safety of flight path is realized, the computation time does not increase significantly with the increase of geographic information, a large number of route planning operations can be completed in a shorter time with a lower computational resource configuration.
