Description

Spatial image drawing system that draws video images of geographical features The present invention relates to a spatial image mapping system for mapping images of topographic features within the field of spatial image mapping technology. More specifically, the invention relates to an improved spatial image mapping system for mapping images of topographic features that enables efficient camera operation by reducing the space required to mount a digital camera, allows the user to effectively experience the realism of the map by mapping spatial images that provide a sense of realism as if looking at the ground from an aircraft when moving the image displayed on the monitor, and prevents degradation of the processing module mounted on the mapping server by stably and effectively cooling the module, thereby not only preventing errors or defects during mapping but also strengthening fire protection characteristics. Digital imagery is widely used as map backgrounds without the need for separate drawing work. This is because maps based on real-world footage are advantageous for users in interpreting the map and verifying locations. Meanwhile, to secure video images, the ground is filmed directly from the aircraft. Accordingly, depending on the aircraft's shooting position, the appearance of the ground structure installed on the ground changes in various ways, as shown in Fig. 1 (an image showing the appearance of the ground structure according to the aerial shooting position). For reference, Fig. 1 is a 9-image output divided into 3 rows and 3 columns showing how the same building (indicated in orange) is represented depending on the shooting position. Conventional maps based on imagery used an image plotter to plot the imagery applied to the background, visualizing ground structures as being as flat as possible. Therefore, even if the user displays the image to view the map and moves the displayed image to check the map, the ground structures included in the image are always displayed in the same planar view. In other words, if a specific ground structure is positioned in the center of the monitor and the corresponding image is moved to the right, the flat plane as it was in the center is displayed even if the ground structure moves to the right on the monitor. For reference, when viewing the ground directly from an aircraft, the side view as well as the plan view of specific ground structures can be seen depending on the aircraft's movement. Of course, if a flat image of a ground structure is applied as the map background, visual interference between the ground structure and the road, and between the ground structures themselves, is minimized. This allows for clear identification of the positional relationships between the road and the ground structure, which is advantageous for users to find their way using the map. However, from the perspective of users utilizing the map on the ground, it is difficult to match the map with ground structures whose flat surfaces (rooftops) are normally unviewable. Since this implies that users require a significant amount of time to understand the map, a solution for improvement was required. In addition, the drawing server that processes drawing images generates a large amount of heat because it must process a massive amount of data in a short period of time. If this heat is not properly cooled, serious problems such as processing failures and system shutdowns occur. In particular, the degradation of the installed processing modules not only shortens the lifespan of the system but also faces a limit where maintenance costs increase rapidly.
