1. A system for providing a panoramic image comprising:
a drone (10) having a camera to capture an image and remotely receiving a signal to control flight and driving of the camera;
a supplier terminal (20) having a drone control application capable of controlling the drone, and collecting and transmitting image information received from the drone, the drone control application having functions including mission management of the drone, flight mission setting, and airframe setting, a three-dimensional altitude flight API service function, and a safety setting function considering user safety and the image information including data for a GIS background map service and Web geographic information for controlling the drone;
a management server (30) having an information storage DB (30i) storing information including the collected and edited panoramic image information, collecting, storing and editing the image information received from the supplier terminal to provide a panoramic image, and converting position information of the drone controlled through the drone control application of the supplier terminal into spatial coordinates, the information storage DB (30i) including a drone information DB (30d) storing information including information of the collected and edited panoramic image, supplier information, and user information, and separately storing only the drone information; and
a user terminal (40) receiving the panoramic image information provided from the management server,
wherein the management server (30) includes a service module (30m) to provide panoramic image information to the user terminal (40) using a messaging service, and includes a streaming server (30s) to transmit image information captured by the drone to a control system, and receive video information captured by the drone and provide the received video information to the user terminal (40),
wherein in a case in which the management server (30) converts the position information of the drone controlled through the drone control application of the supplier terminal into two-dimensional panorama spatial coordinates and three-dimensional panorama spatial coordinates,
the spatial coordinates include two-dimensional panorama spatial coordinates and three-dimensional panorama spatial coordinates,
the two-dimensional panorama spatial coordinates include a pitch, which is a ground altitude value at a photographing location and a distance value between coordinates to be converted from the ground coordinate of the photographing location, and a yaw which is an angle of the coordinate to be converted from the photographing location:
 wherein, h is a relative altitude at the panoramic image photographing location, and d is a distance ranging from the ground coordinates of the panoramic image photographing position to the conversion coordinates, and
the three-dimensional panorama spatial coordinates include a ground altitude value at a photographing location, a distance value between coordinates (2D) to be converted from the ground coordinate (2D) of the photographing location, a pitch calculated from an altitude value of coordinates to be converted, and a yaw which is an angle of the coordinate to be converted from the photographing location:
 wherein h is a relative altitude at the panoramic image photographing location, and d is a distance ranging from the ground coordinates of the panoramic image photographing position to the conversion coordinates, and z is a reference height of the panoramic image photographing position.
