Description

Drawing system for composing the datum point of an aerial photograph

The present invention relates to an image drawing system for synthesizing a reference point of an aerial image.

In mapping, a drawing refers to a task of drawing a map of two-dimensional or three-dimensional images based on geographic information. In addition to the development of digital output technology, it is now possible to display a digital image or a three-dimensional graphic image.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a state of an image drawing system according to the present invention, which will be described with reference to the drawing.

The image drawing system according to the present invention includes a photographing means (100) for performing aerial photographing, a GPS coordinate input means (200) for inputting GPS coordinates into a photographed image, and a photographing image for constantly adjusting the magnification of a plurality of photographed images. Editing means 300, photographed image connecting means 400 for connecting a plurality of photographed images, image drawing means 500 for executing a drawing operation based on the photographed image, and information about a specific position in the drawing image A position point input means 600 for inputting, a target image input means 700 for checking an input position of the position point and applying it to the drawing image, and a drawing image output means 800 for outputting the finished image; do.

The photographing means 100 is an aerial photographic technology applied, but photographing a point that is the target of the drawing in the aircraft in flight, by continuously shooting along the flight line to shoot all the points of a wide area while maintaining high resolution Will be done.

In other words, by partially photographing the points of the wide area, and synthesizing the partial images photographed as described above, the effect of capturing all the points of the wide area is obtained.

2 is a view showing the configuration of the photographing means according to the present invention, will be described with reference to this.

The photographing means 100 includes a fixing tube 110 fixed to an aircraft (not shown), a fixing plate 120 connecting the fixing tube 110 and the camera 130, a camera 130, a laser or infrared light, and the like. A light emitter 140 emitting light, a light receiving sensor 150 detecting a irradiation position of light emitted from the light emitter 140, a light receiving sensor checking module 160 confirming a position detected by the light receiving sensor 150, Horizontal position information DB (170) for storing the horizontal position information, such as the degree of inclination of the aircraft with respect to the detected position, horizontal position checking means 180 and horizontal position information DB (170) for checking the current horizontal position of the aircraft Comparing the horizontal position of the aircraft and the horizontal position of the aircraft identified in the horizontal position check means 180 retrieved from the check whether the same and the shooting means control module 190 for controlling the driving of the camera 130 according to the result Include.

Here, the camera 130 may be a general analog film camera or a digital camera, but a digital camera may be preferably applied to minimize a change in resolution when the photographed image is enlarged or reduced. However, the camera 130 according to the present invention is not limited to the digital camera, and may be variously modified within the scope of the following claims.

The photographing means 100 will be described in more detail.

As described above, the photographing means 100 includes a fixing tube 110 is fixed to the aircraft installation. Fixing tube 110 has a hollow in which one end of the fixing table 120 is inserted, and is firmly fixed to the aircraft's aircraft to interlock along the movement of the aircraft.

Fixing member 120 is a medium for fixing the fixing tube 110 and the camera 130 to each other, one end of the fixing member 120 is inserted into the hollow becomes a spherical fixture 121, rotated based on the fixing tube 110 Possibly fixed. Of course, the fixing tube 110 has a shape surrounding the fixing member 121 so that the fixing member 121 does not deviate, and should have an opening having a sufficient area to secure a rotation range of the fixing member 120. In addition, a lubricant or the like is applied to a point where the inner surface of the fixing tube 110 and the outer surface of the fixing member 121 are in contact with each other, thereby enabling smooth rotation of the fixing table 120.

The camera 130 may be an analog film camera or a digital camera, and is fixedly disposed at the other end of the holder 120 so that the camera 130 is disposed opposite to the holder tube 110 with respect to the holder 120.

The fixed tube 110, the fixed base 120 and the camera 130 assembled as described above are fixed to the aircraft so that the camera 130 to shoot down. Therefore, the fixing tube 110, the fixing table 120 and the camera 130 is preferably arranged in a vertical line when the aircraft is positioned horizontally.

Subsequently, the light emitter 140 is a mechanism for irradiating light such as a laser or infrared light, and the light should have a non-radiative property.

The light receiving sensor 150 is disposed above the fixing tube 110 through which the light emitter 140 emits light, and receives and detects light emitted from the light emitter 140 at one point. Therefore, the light receiving sensor 150 is arranged as closely as possible within the irradiation range of the light emitter 140, and detects exactly where the light emitted from the light emitter 140 is irradiated.

The light receiving sensor checking module 160 receives the position information of the light receiving sensor 150 which has received the light of the light emitter 140, searches the horizontal position information DB 170 based on the received position information, and fixes the current fixed pipe 110. Check the angle of refraction between the and the holder 120. On the other hand, the light receiving sensor confirmation module 160 controls the operation of the light emitter 140. That is, when the light receiving sensor check module 160 'ON' the light emitter 140, the light receiving sensor 150 prepares to receive the light, and operates the system to check the point of the received light.

Continuing, as is well known, the aircraft is tilted in the course of turning or adjusting altitude. Of course, when the aircraft is inclined, the occupants as well as the installed mechanisms are inclined as well, and the photographing means 100 fixed to the aircraft is not an exception. By the way, if the photographed image that is essentially applied for the precise map production is not secured due to the inclination of the photographing means 100, precise map production is impossible. In addition, as described above, if another photographed image is provided according to the inclination of the aircraft in the process of editing a plurality of photographed images, this also causes a great obstacle in image drawing.

Accordingly, in the system according to the present invention, the fixing tube 110 and the fixing plate 120 are rotatably fixed to each other so that the camera 130 maintains the vertical direction toward the earth's surface regardless of the gas state of the aircraft. At the end of the camera 130 is fixed.

As a result, even when the gas is inclined, the fixing stand 120 is directed toward the vertical direction of the earth in the gravity direction by the load of the camera 130, while the fixing pipe 110 moves along the inclination of the gas, and the fixing pipe 110 and the fixing stand are 120 are refracted to each other.

To this end, the fixing rod 120 according to the present invention is connected to the fixing fixture 121 sliding and inserted into the hollow of the fixing tube 110. Fixture 121 is a spherical shape, the surface is smoothly processed, so as to smoothly slide in contact with the inner surface of the fixing tube (110).

Figure 3 is a partial cross-sectional view showing the operation of the fixing tube according to the present invention, it will be described with reference to this.

Meanwhile, the light emitter 140 is installed on the fixture 121. That is, when the fixing tube 110 and the fixing table 120 are refracted with each other, the light emitter 140 moves together with the fixing tool 121, so that the position of the fixing tube 110 relative to the fixing tube 110 changes. As a result, the light irradiation toward the light receiving sensor 150 installed in the fixing tube 110 is directed to another point as shown.

3 (a) shows the position of the first light receiving point SP received by the light receiving sensor 150 when the gas is in a horizontal state, and FIG. 3 (b) shows light receiving sensor 150 when the gas is inclined. ) Shows the position of the second light receiving point SP 'received.

Subsequently, the angle of refraction between the fixing tube 110 and the fixing plate 120 may be determined based on the first and second light receiving points SP and SP ′ identified by the light receiving sensor identification module 160. This is because the horizontal position information DB 170 stores the information of the inclined state of the aircraft according to each light receiving point. That is, the position of the light receiving point is stored to the information that the inclination of the aircraft is larger toward the edge of the light receiving sensor 150, more specifically, it may include the inclination angle information of the aircraft.

Horizontal position checking means 180 is a device for measuring the inclined state of the aircraft, the inclined state is important information in the operation of the aircraft, and therefore the technique for measuring the inclined state of the aircraft in the field of aviation technology is well known Therefore, the description of the embodiment of the horizontal positioning means 180 will be omitted.

The photographing means control module 190 checks whether the camera 130 is photographed by checking an inclined state of the aircraft confirmed by the light receiving sensor checking module 160 and an inclined state of the aircraft confirmed by the horizontal position checking means 180. Decide

As described above, according to the inclined state of the aircraft, the fixing pipe 110 and the fixing table 120 are refracted at a predetermined angle. The inclination of the aircraft aircraft can be tracked based on the angle of refraction, and the inclination can only be the same as or similar to the actual measurement of the horizontal positioning unit 180.

On the other hand, the shooting position of the camera 130 may not face the vertical for various reasons, such as friction between the fastener 121 and the inner surface of the fixing tube 110. That is, the photographing angle of the camera 130 is not guaranteed only by checking the first and second light receiving points SP and SP 'by the light receiving sensor 150.

In order to solve this problem, the photographing means control module 190 compares the refraction angle obtained by the light receiving sensor identification module 160 with the actual measurement of the horizontal positioning means 180, and the refraction angle and the actual measurement are the same / similar to each other. Considering that the photographing angle of the camera 130 is vertical, the camera 130 is driven. Of course, if the difference between the angle of refraction and the actual measurement exceeds the reference, it guides the operator to limit the shooting of the camera 130 and take follow-up measures.

The GPS coordinate input means 200 applies a GPS coordinate artificially set on the ground surface to the photographed image photographed by the photographing means 100. Therefore, the photographed image is preferably a digital image such that the GPS coordinate data is synthesized.

As described above, the photographed image photographed by the photographing means 100 may be digital or an image by analog film, but in the case of analog film, the photographing method of the photographing means 100 may be digitized. Is not restricted.

4 is a block diagram showing a state of the GPS coordinate input means according to the present invention, Figure 5 is a view showing a photographed image taken by the photographing means, it will be described with reference to this.

The GPS coordinate input means 200 of the system according to the present invention includes a photographing image range setting module 210, a photographing image reference point checking module 220, a comparison point checking module 230, and a GPS coordinate checking module 240. And a GPS coordinate synthesis module 250.

The photographing image range setting module 210 limits the range by editing the photographing image photographed by the photographing means 100, and forms the composition for composing with other photographed images continuously photographed along the same line of the aircraft. It is to meet the standard. For example, as shown in FIG. 5, the image photographed by the photographing means 100 is cut into a rectangular image, and the horizontal and vertical lengths of the rectangular image are set to a standard.

Shooting image reference point confirmation module 220 is to take the center of the photographed image (P1) cut in the photographing image range setting module 210 as a reference point (C). At this time, it is preferable that the corresponding point of the photographed image P1 captured as the reference point C is not changed according to the land and sea or the feature.

The comparison point confirming module 230 sets an arbitrary point that can be compared with the reference point C as the comparison point R, so that the comparison point R is the actual geography and the photographed image P1 of the target image P1. ) Is a comparison value for determining the identity between

Since the setting of the comparison point (R) is not particularly limited, it may be variously selected within the range of the photographed image (P1) around the reference point (C).

The GPS coordinate checking module 240 checks the actual GPS coordinates of the reference point C, and prepares a composite operation of the GS coordinates centering on the reference point C in the photographed image P1 based on this. At this time, the standard of the GS coordinates should be matched to the specification of the photographed image P1, so that the GS coordinates of the comparison point R are checked, so that the 'real distance' between the reference point C and the comparison point R and the photographed image ( Check the 'distance' between the reference point (C) and the comparison point (R) on P1), respectively. The GPS coordinate checking module 240 calculates the ratio of the 'real distance' and the 'distance' thus confirmed, and reduces or enlarges the GS coordinate according to the scale.

The GPS coordinate composition module 250 synthesizes the GPS coordinates reduced or enlarged by the GS coordinate checking module 240 to the photographed image P1, and the entire photographed image P1 in addition to the reference point C and the comparison point R. Make sure the GPS coordinates are applied.

6 (a) shows a photographed image P1 photographing an arbitrary point, and FIG. 6 (b) shows a photographed image P2 photographing another point connected to the photographed image P1, and the photographed image P2. ) Is a shot image P2 'edited at the same magnification of the previous shot image P1.

Aerial photography should be taken while keeping the altitude of the aircraft as constant as possible, but the magnification of the photographed images is likely to be inconsistent due to the zoom adjustment of the camera 130 and the change of the altitude of the aircraft according to the situation. Therefore, the photographing image editing means 300 must unify the magnification of the photographing images P1, P2, and P2 'before connecting the photographing images P1, P2, and P2'.

Meanwhile, the photographed images P1, P2, and P2 ′ having various magnifications have a distance D between the corresponding reference point C and the comparison point R of the photographed images P1, P2, and P2 ′ to match the magnifications. The magnification of the photographed images P1, P2, and P2 ′ is adjusted to match the distance D.

Of course, the selected reference point (C) and the comparison point (R) will be the same point in the captured image (P1, P2, P2 ') to be connected to each other.
