Description
More particularly, the present invention relates to a spatial image drawing method for drawing a target object using a video image among spatial image drawing techniques, and more particularly, And a position measuring device disposed at an outer periphery of the actual terrain receives the ultrasonic waves emitted toward each other and confirms the mutual positions. In the process, the GPS satellites for confirming the absolute position of the position measuring device The present invention relates to a spatial image drawing method of drawing a target object with a video image so that an accurate topographic image can be drawn while minimizing an error even in a downtown area so that a reliable drawing image can be completed .
The drawing images used for the digital map production are made as simple as possible to help users who use the map and minimize the visual rejection.
Particularly, when the user visually confirms an image displayed on the monitor, such as a navigation system, it is necessary to be able to easily and quickly check the displayed image and understand the confirmed image. Therefore, And the like.
FIG. 1 (a) is a view image in which the terrain information is simplified to the greatest extent, and FIG. 1 (b) is a view image showing a real terrain.
As shown in Figs. 1 (a) and 1 (b), the road state of the terrain and the layout of the terrain image B can be easily and quickly understood by the user, Since the images between the simplified image and the actual on-scene terrain shown in (b) are different from each other, the user feels confused about whether or not the actual scene is identical to the drawn image.
In order to solve such a problem, a correction system has been developed. As shown in FIG. 2, the conventional correction system is capable of performing correction and updating operations on a picture image. The
Since the conventional correction system needs to use GPS and the position measuring device at the same time, it is difficult to use in an area where reception of GPS is difficult, that is, in areas where various terrains or high-rise buildings are densely packed. There has been a problem that a communication error of GPS or a malfunction of various sensors frequently occurs.
In the prior art, which has partially improved such a problem, Korean Patent Registration No. 10-1002407 (hereinafter referred to as "Conventional Technology 1", hereinafter referred to as "Conventional Technology 1") "A correction system for spatial image mapping using ground point confirmation and terrain information on the ground surface" Have been disclosed. However, the registered patent according to the above-mentioned prior art 1 has a limitation that it is difficult to measure the multi-direction since the position measuring device can not rotate.
In addition, the prior art has a problem in that it is inconvenient to use because it is a structure which is not adjustable in height.
In order to solve the above problems, there has been proposed a method of displaying a target object in relation to a reference point of a video image by Korean Patent Registration No. 10-1002410 (Dec. 13, 2010, hereinafter referred to as "Prior Art 2" In the prior art 2, a position measuring device is disposed at each reference point, i.e., a vertex of the terrain, and a position between the reference points is confirmed by receiving and receiving ultrasonic waves of a predetermined intensity. However, The positioner is warped to the observer so that the observer is instructed to position the observer again, or the observer must horizontally support the positioner, so that the positioning of the positioner is time consuming .
Further, in the "spatial image drawing system of feature using the reference point" according to Korean Patent Registration No. 10-1517827 (hereinafter referred to as "Prior Art 3"), the position measuring apparatus is further provided with a horizontal support device It has been proposed to inject the air into each of the chambers to keep the position measuring device standing vertically. However, it is difficult to change the installed state because the position measuring device can not be rotated, There is a problem that it is difficult to install and detach.
In addition, according to Korean Patent Registration No. 10-1239932 (hereinafter referred to as "Prior art 4"), "a spatial image drawing system for drawing a target object to a reference point of the image image" Among the proposed techniques, it is proposed to solve the problem that the wiring connected to the code is disconnected due to the anchor having the shape of the spire.
In the prior art 4, the lower end of the anchor is cut and the thread is machined. The ball-type weight is detachably fastened to the thread to reduce the possibility of disconnection of the wire. However, There is a problem that the position is changed or deviated due to the shaking.
