1. There is a UI that can extract the missions (still image (panorama), movie shooting) performed by the pilot named A from the flight log or it can repeat the path already made in advance

2. When extracting from the light log, you can extract some of the GPS paths that the drone flew and change it to the waypoint (path point) that the drone can recognize and repeat the same mission. At this time, the heading of the dron is obtained according to the information of the compass, and the gimbal angle and the camera setting information can be used for each waypoint. In the case of a drone that can input values between two points, interpolated data between each waypoint is obtained.

3. If you create a route in advance and execute the mission, you can share the mission with the still image or video that you have obtained through the UI that can be shared with third parties.

4. Using a technology called SLAM - SLAM is a technique to find out and control the position value of a person by real-time mapping information obtained from a camera. This technique can be used to send drones to the same location and to shoot for indoor or non-GPS areas. Therefore, it is possible to capture the same GPS position using the SLAM technology based on the indoor positioning technology / image, which can not be obtained in the second case.

5. Based on the obtained bird's-eye view (photograph), it is possible to photograph the dron at the same position by adjusting the position of the dron and the gimbal angle of the camera through comparison with the image of the camera seen by the dron in real time on the dronon's onboard computer.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like. The computer-readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.
