Space mapping method and system for airborne mission load region of interest

The invention discloses a space mapping method and system for an airborne mission load region of interest, and the method comprises the steps: taking a coordinate point of a carrier as an original point, calculating azimuth angles and pitch angles of a plurality of region contour marking points, then judging whether the carrier is outside or inside the region, judging whether the region is a concave region or not under the condition that the carrier is outside the region, and if yes, judging whether the region is a concave region or not; and if yes, calculating the azimuth angle and the pitch angle of the system according to the azimuth angle and the pitch angle in combination with the course angle, and finally, respectively counting the most values of the azimuth angle and the pitch angle of the aircraft system to obtain the azimuth sector range and the pitch sector range of the aerial carrier. A key area marked by a geographic system is converted into an orientation and pitching sector range relative to an
