Description

{System for Drawing Digital Map}

The present invention can provide a high-quality aerial image without aerial photographing apparatus installed in an airplane, in which the main components of the rotary type are protected from surrounding strong winds during the acquisition of the aerial image, The aerial photographing unit is a reference point that enables aerial image acquisition to be carried out in a state where the image capturing unit is shielded from the fine dust, ultrafine dust, and dust in a high concentration of fine dust, ultrafine dust, and dust, And an aerial photographed image is synthesized.

It refers to the work of showing a map of a two- or three-dimensional image on the basis of map-making information in map production. In addition to the development of digital output technology, it has recently been shown as a digital image or a three- It is also called image drawing in the sense that it is the same as.

On the other hand, as the image-drawing technology has been developed, a more realistic and precise map can be produced, and it is also easy to update the image-drawing information according to changes in the topography and geographic information.

As a result, geographical information, which has been used for a limited period of time, has been widely used as popular information, and accuracy and renewal efficiency have been greatly improved.

However, in the conventional image drawing production method for performing the image drawing operation, the accuracy of the data for image drawing is not sufficient, and the contents thereof are uniform and limited.

On the other hand, in the production method for image drawing, the drawing operation is performed based on the aerial photographing image. Since the entire map producing point can not be photographed by one photographing, images of several cuts are taken at the time of aerial photographing, And the image must be connected.

However, in a process of obtaining a plurality of shot images over a plurality of times and then synthesizing them, a difference occurs in the resolution depending on the shooting angle and altitude of the aircraft.

As a result, there has been a problem in that the conventional image drawing operation method has to combine images taken at different angles and shot images having different resolutions, and to perform image drawing based on information that is not uniform and not uniform throughout the image.

Of course, the map completed in such an environment is limited in precision, and even if the completed map is used in a geographic information apparatus such as navigation system, since the user is provided with the wrong geographical information, the user may feel inconvenience in using the map none.

For the above reasons, Korean Patent No. 10-1308744 (titled "Terrain Contrast Reference Point Synthesis Type Aerial Image Mapping System of Aerial Photographing Image") was proposed.

Such "aerial photographed terrain-to-base point combined point spatial imaging system" collects the photographed image through four image capturing units and adjusts the position and angle of each image capturing unit so that the quality of the spatial image capturing operation And each of the four image capturing units has a zoom function to secure images of various resolutions. Therefore, it is possible to perform an efficient spatial image capturing synthesis operation, and the four image capturing units have different types of images to be captured The quality of the produced spatial image is not affected by the terrain and the weather.

However, in the case of the " terrestrial base point composite point-of-view imaging system for aerial photographing images ", in the main mounting base, the sub-mounting base is inclined in the left-right direction or rotated around the vertical axis And the sub-rotation mounting base is rotatably hinged to the main rotation mounting base, so that when a strong wind is blown around the airplane in the acquisition of the aerial image, the sub- It was able to be disturbed in acquiring high-quality aerial images while causing tremors. Also, if the concentration of fine dust, ultrafine dust, or dust in the vicinity of the airplane when the aviation image is acquired shows a level higher than that of the airplane, the image shooting part may be seriously contaminated by fine dust, ultrafine dust, and dust.
