Description

Technical Field [0001] The present invention relates to a Drones camera fixing bracket equipment for shooting a space image,

The present invention relates to a drones camera for capturing an image for spatial image mapping, which enables a clearer and more accurate image to be obtained in a state in which a trembling phenomenon is excluded when acquiring an image for spatial image acquisition through a camera, To a stationary bracket device.

Recently, most of the images acquired from airplanes or satellites are digital images taken by digital cameras. These digital images have geographical coordinates in the image using GPS / INS technology, but since they contain many terrestrial distortions due to the facial elements of the camera or sensors, the curvature of the terrain, and the curvature of the earth, I can not be trusted.

In order to correct these digital images, the image that modified the basic deviation using the image reference point or the digital elevation model is called orthoimage.

The applicant of the present invention has proposed the present invention as a method for making more accurate orthography from the image acquisition operation so that more accurate orthographic images can be produced.
