Straight flight constrained 2D route planning for unmanned air vehicle is conducted in this paper.To meet the request of straight flight constraint,2D flight route can be simplified as canonical route that consists of line and arc segment,and the definition of turning points (TPs) is given.Based on this definition,a new method for straight flight constrained route planning is presented.Experiments shows that the obtained optimal route not only meets the request of minimal radius constraint,but also keeps air vehicle fly straight passing through turning points,facilitating matching navigation and flight photographing for air vehicle.
