Description

Precise Image Space Mapping System with Geographic Information change}

The present invention relates to a precise spatial image drawing system that reflects changes in topographic information. More specifically, it relates to a precise spatial image drawing system that reflects changes in topographic information. More specifically, it relates to topographic information by combining video images precisely collected on the ground with aerial video images containing geographic information collected through aerial photography. This is about a spatial image drawing system that produces a three-dimensional spatial image electronic map that reflects information changes.

In cartography, drawing refers to the work of drawing a map as a two-dimensional or three-dimensional image based on geographical information. With the development of digital output technology, it has recently become possible to draw a map as a digital image or three-dimensional graphic image. It is also called video painting because it resembles real life.

Meanwhile, with the development of video mapping technology, more realistic and precise map production has become possible, and it has also become easier to update video mapping information according to changes in topography and geographic information.

In the end, geographical information, which was managed as first-class information and used in a limited manner, is widely used as popular information today, and as accuracy and update efficiency have greatly improved, it is widely applied in various fields as useful information with high reliability in its use.

However, the conventional method of producing video drawings did not provide sufficient precision in the data for video drawings, and the content was uniform and limited.

Meanwhile, the production method for video drawings involves drawing work based on aerial photography images. Since it is not possible to photograph the entire map production point in one shot, several cuts of images are taken during aerial photography, and many of the images captured in this way are captured. The drawing work must be done by connecting the captured images.

However, in the process of securing multiple captured images and compositing them, differences in resolution occur due to changes in the shooting angle and altitude of the aircraft.

In the end, the conventional video drawing work method had the problem of combining images taken at different shooting angles and images with different resolutions, and performing the image drawing work based on information that was neither unified nor uniform throughout the image.

In addition, conventionally, when drawing using a drawing machine, if there is foreign matter on the screen of the drawing machine, it is difficult for the worker to clearly check the aerial image, ground image, and original drawing image on the screen, making it difficult to perform the drawing work precisely. There was none.
