Abstract

A carrier, such as an airplane, which outputs a warning sign if an artificial structure, such as a building, is in its path. The CPU of the carrier calculates the path by referring to the destination data representing the destination of the carrier.

Claims

1. A carrier comprising a destination data input means, a 3D artificial structure data storage means, a CPU, wherein a destination data representing the destination of said carrier is input via said destination data input means, said 3D artificial structure data storage means stores a plurality of 3D artificial structure data regarding a plurality of three-dimensional artificial structures which reflect the artificial structures in the real world, and said CPU identifies a guiding-to-the-destination path which represents the path to the destination indicated by said destination data, and compares said guiding-to-the-destination path with said plurality of 3D artificial structure data, and said carrier outputs a warning sign if one or more of said three-dimensional artificial structures are within said guiding-to-the-destination path of said carrier.

2. The carrier of claim 1, wherein said destination data representing the destination of said carrier is input via said destination data input means before said carrier takes off the ground.

3. The carrier of claim 1, wherein said CPU calculates an alternative course if one or more of said three-dimensional artificial structures are within said guiding-to-the-destination path of said carrier.

4. The carrier of claim 1, wherein said carrier is remotely controllable by a computer.

5. The carrier of claim 1, wherein said carrier comprises an emergency landing system.

6. A carrier comprising a destination data input means, a 3D object data storage means, a CPU, wherein a destination data representing the destination of said carrier is input via said destination data input means, said 3D object data storage means stores a plurality of 3D object data regarding a plurality of three-dimensional objects which reflect the artificial structures in the real world, and said CPU identifies a guiding-to-the-destination path which represents the path to the destination indicated by said destination data, and compares said guiding-to-the-destination path with said plurality of 3D object data, and said carrier outputs a warning sign if one or more of said three-dimensional artificial structures are within said guiding-to-the-destination path of said carrier.
