Description

Compensating system for image drawing by application of reference point

The present invention relates to a system for correcting an image drawing operation according to application of a reference point.

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. It is also called image drawing in the sense that it is like live-action.

On the other hand, with the development of image drawing technology, more realistic and precise mapping is possible, and it is easy to update image drawing information according to the change of terrain and geographic information. As a result, geographic information that has been used as a limited amount of information is widely used as a popular information today, and has been widely applied in various fields as useful information with high accuracy and update efficiency and high reliability.

However, the above-mentioned usefulness of the image mapping technique has a limitation that the precision and accuracy of the image mapping map must be assumed. In other words, the image drawing work must be carried out efficiently and effectively in the production of maps. In addition, in order to improve the image drawing work, the precision and variety of data applied to the work are essential.

On the other hand, the system for image drawing is conducted based on aerial photographing image, but it is not possible to photograph the entire map production point in one shot, so when shooting aerial photographs of several cuts, The drawing image should be connected to the drawing process. However, in the process of obtaining a plurality of photographed images several times and synthesizing them with each other, a difference occurs in the resolution due to the change in the photographing angle and the altitude of the aircraft. As a result, the conventional system has a problem in that the image drawing process is performed on the basis of information that is not uniform or uniform in the whole image while synthesizing the photographed images having different photographing angles and the photographed images having different resolutions.

Of course, the completed map in this environment is inevitably deteriorated, and the completed map provides users with incorrect geographic information even when used in geographic information organizations such as navigation. There was no.

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

1 is a block diagram showing a state of a correction system according to the present invention.

The correction 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 editing for constantly adjusting the magnification of a plurality of photographed images. 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 photographed images, and inputting information on a specific position in the drawing image.

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 point 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 point information DB (confirming the current horizontal position of the aircraft) Shooting means control module 190 for comparing the horizontal position of the aircraft retrieved in 170 and the horizontal position of the aircraft identified in the horizontal position checking means 180 to check the identity and control the driving of the camera 130 according to the result ).

Here, the camera 130 may be a general analog film camera or a digital camera, but it may be preferable that a digital camera is applied to minimize the 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 point information DB 170 based on the received position information, and fixes the current fixed pipe ( Check the angle of refraction between the 110 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 applied to the precise mapping is not guaranteed due to the inclination of the photographing means 100, precise mapping 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. The camera 130 is fixed to the end of the 120.

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).

Meanwhile, in order to smoothly slide the fastener 121 engaged with the fixed tube 110, the lubricant 112 described above is preferably applied between the inner surface of the fixed tube 110 and the fastener 121. However, since the fixing tube 110 is vertically disposed for the down shooting of the camera 130, the lubricant 112 may be leaked through the opened downward. That is, when the lubricant 112 is applied once, the life thereof is excessively reduced and the cost for use and care is increased.

To this end, the fixing pipe 110 according to the present invention is closed with a closed corrugated pipe 111, the corrugated pipe 111 is fixed at the top wrapped around the circumferential surface of the fixing pipe 110 and the lower portion is the middle portion of the fixing table 120 It is wrapped around it and fixed. In addition, wrinkles are formed corresponding to the rotation direction of the holder 120, thereby minimizing interference to the movement of the holder 120, as shown in FIG.

On the other hand, when the closed corrugated pipe 111 closes the lower end of the fixed tube 110, the lubricant 112 is injected into the inner side to minimize friction between the fixed tube 110 and the fastener 121. For reference, the injection amount of the lubricant 112 should be limited to an appropriate amount in consideration of the possibility of contamination of the light emitter 140 installed in the fixture 121 as shown.

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 fixed 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 point 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 as the information is tilted toward the edge of the aircraft toward the edge of the light receiving sensor 150, and more specifically may include the tilt 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 body 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.

On the other hand, the GPS coordinates for confirming the 'real distance' between the reference point (C) and the comparison point (R) is measured using a GPS measuring instrument (not shown) in the actual site. Here, the GPS measuring device is a well-known apparatus for checking the GPS coordinates.

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.

FIG. 6 is a diagram illustrating a state of enlargement / reduction and synthesis of photographed images, which will be described with reference to the drawing.

The photographing image editing means 300 edits the magnification of the photographing images P1 and P2 to be connected in order to connect a plurality of photographing images P1 and P2, and photographs the images P1 and P2 itself. Reduce or enlarge the image so that the captured images P1 and P2 connected to each other are accurately synthesized.

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.

7 is a diagram illustrating a state of applying a location point and a representative image to the drawing image, which will be described with reference to the drawing.

The photographed image connecting means 400 connects / combines the photographed images P1 and P2 'when the photographed image editing means 300 adjusts the magnification of the photographed images P1, P2 and P2' to be connected to each other. do. At this time, it is preferable that the range of the same point of the photographed images P1 and P2 'to be connected / composited with each other exceeds 50% in the total area of the photographed images P1 and P2'. This is to accurately and precisely connect / combine the photographed images P1 and P2 '. Therefore, the range in which the captured images P1 and P2 'which are connected / synthesized with each other overlap each other will exceed 50% in the area of one captured image P1 and P2'.

The image drawing means 500 performs graphic processing on the basis of the connected / synthesized captured images P1 and P2 'to complete the drawing image G1. The image drawing means 500 may be applied to a drawing apparatus which proceeds to the drawing work directly on the ground, but in addition to the drawing work directly on the ground, the drawing operation may be performed by computer graphics, in the embodiment according to the present invention Recommend the drawing operation using.

The drawing operation may depict the connected / synthesized photographed images P1 and P2 'as it is, but may selectively show only necessary portions. In addition, it is possible to express the drawing image G1 having various feelings while being shown as an image different from the reality.

Meanwhile, the GPS coordinates inputted to the photographed images P1 and P2 'are inserted in the drawing image G1 as they are drawn in the drawing operation, and are shown in a grid form so that the user can visually check them, or in a data manner so that they can be confirmed with data. Can be entered.

The location point input means 600 inputs separate location points 11, 12, and 13 for specific terrain, features, or artificial structures in the drawing image G1, and provides location points 11, 12, and 13. The data may include information such as the name, address, GPS coordinates of the terrain, feature or man-made structure.

The location points 11, 12, and 13 may be inputted with data of all terrains, features, or artificial structures in the drawing image G1, but is limited to specific terrains, features, or artificial structures, as shown in FIG. 7. It may be entered.

On the other hand, the location points 11, 12, 13 are input to the drawing image G1 based on the GPS coordinates stored in the location points 11, 12, 13. That is, the position points 11, 12, and 13 are input based on the GPS coordinates inputted by the GPS coordinate input unit 200 to the photographed image P1. Through this, the user may search for and receive desired geographic information from the drawing image G1 using the data of the location points 11, 12, and 13.

The position point correcting means 600 ′ checks the arrangement direction and distance between the input position points 11, 12 and 13 and adjusts the error, and the position point arrangement state checking module 610 and the actual position of the position point. As a reference, the location point information DB 620 stores information on the arrangement direction and distance between the location points.

Since the GS coordinates are collectively applied to the photographing image P1 based on only the reference point C and the comparison point R in the GS coordinate input means 200, the actual PS coordinates with respect to the position displayed on the photographing image P1 and An error may occur in the GPS coordinates of the corresponding position in the photographed image P1. In addition, since the format is changed to the drawing image G1 during the drawing process after inputting the GPS coordinates input to the photographing image P1, the possibility of the error may be increased and the degree of error may be increased. Therefore, the location point inputted by the location point input unit 600 to the drawing image G1 may be marked at a point different from the actual location.

The position point correcting means 600 ′ compares the position state between the plurality of position points 11, 12, and 13 with each other and compares the position state with each other. To this end, the location point information DB 620 stores the actual placement direction and distance information between the location points 11, 12, and 13 input to the drawing image G1, and the location point arrangement state checking module 610. Check the relative positioning direction and distance information between the corresponding position points (11, 12, 13) input on the drawing image (G1) and correct the error if compared with the actual information to move the position point to the correct position Enter it.

In more detail, the location point arrangement state checking module 610 selects a location point 11 and another location point 12 inputted to the drawing image G1 to determine the distance between the two location points 11 and 12. At the same time, the position point 11 and the other position point 13 are selected to check the distance between the two position points 11 and 13 to calculate the 'ratio' of the identified two distances. At the same time, the 'direction' of the other location points 12 and 13 is confirmed based on the location point 11. On the other hand, in the location point information DB 620, which stores the actual location information for the location points 11, 12, 13, the distance of each of the other location points 12, 13 based on the location point 11 Check the 'real rain' and 'real direction'. Compare the 'rain' and 'direction' with the 'real ratio' and 'actual direction', if there is no difference, keep the input position points (11, 12, 13) as it is, and if there is a difference, the image image (G1) The drawing image G1 is corrected according to the input position points 11, 12, and 13 according to the 'real ratio' and the 'real direction'.

The representative image input means 700 may apply a representative image (21, 22, 23) of various appearances by modifying the uniform drawing image (G1) in which only the upper surface of an artificial structure such as a building is photographed / shown. Make sure For example, the representative image (21, 22, 23) may be an actual photographing image of the building or a photographed image or a sketched image of the feature, the representative image (21, 22, 23) is a drawing image (G1) It is inserted at the corresponding point of the user so that the user can see the drawing image G1 more familiar.

For this purpose, the representative image input means 700 includes a representative image DB 720 for storing the representative image images 21, 22, and 23, and a representative within the range of the drawing image G1 based on the GPS coordinates. Representative image identification module 710 for retrieving the water image (21, 22, 23) from the representative image DB 720 and inserted into the corresponding position of the drawing image (G1).

When the complete drawing image is completed while combining the above-described location point and representative image with the drawing image G1, the drawing image output means 800 may output the drawing image M on the ground or the display. have. The image drawing image (M) is expressed in the position of the features and artificial structures, as well as roads and waterways for a specific area, and the expression method is the image drawing image (M) including the GPS coordinate information while maintaining a constant scale While improving the accuracy of the image, based on the above-mentioned stable aerial photography technology to improve the accuracy of the image image image (M), it is possible to expect high reliability of users in using the image image image (M).
