Description

Technical Field [0001] The present invention relates to a real-time spatial image-capturing device, and more particularly,

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an imaging system for an aerial photographing image which minimizes an optical error among spatial imaging techniques, and more particularly, The user can feel the realism of the digital map effectively by giving the reality that the airplane looks at the ground when moving the image of the airplane, and the terrestrial coordinate system provides the accurate coordinates in real time, In order to improve the accuracy by implementing the correction map by reflecting the changed terrain information, it is necessary to increase the watertightness of the ground coordinate system so as not to cause the communication trouble, and also to minimize the optical error caused by the corrosion resistance of the structure, .

Digital video images are widely used as the background of digital map without any painting work. This is because the digital map based on the due diligence is advantageous for user's map interpretation and location confirmation.

On the other hand, in order to secure the image, the ground is directly photographed from the aircraft. Accordingly, the image of the ground structure installed on the ground according to the photographing position of the aircraft is variously changed as shown in FIG. 1 (an image showing the appearance of the ground structure according to the aerial photographing position). For reference, FIG. 1 shows how the same building (indicated by orange color) is expressed according to the photographing position in nine rows and three columns.

A conventional digital map using a video image as a background applies a video image applied to the background as if the ground structure is as flat as possible.

Therefore, even though the user views the digital map to view the digital map and then moves the output image to check the digital map, the ground structure included in the image is always displayed in the same plane.

That is, even if the ground structure moves to the right side of the monitor by moving the corresponding image image to the right while the specific ground structure is positioned at the center of the monitor, the flat image in the center position of the monitor is outputted.

For reference, when you see the ground directly on the aircraft, you can see the plane as well as the side of the specific ground structure depending on the position of the aircraft.

Of course, applying a flat image image as a background of a digital map minimizes the visual interference between the ground structure and the road, the ground structure and the ground structure, so that the positional relationship between the road and the ground structure can be clearly identified , Which is also advantageous for the user to find a route using the digital map.

However, from the viewpoint of the user who uses the digital map on the ground, it is difficult to match the ground structure which can not normally see the plane (roof) with the digital map, and there are many cases in which the correction This means that it takes a considerable amount of time to understand the numerical map, and an improvement measure is required.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The present invention uses the above-mentioned prior-art patent No. 0947106 as it is. Therefore, the features of the device configuration described below are all described in Patent Registration No. 0947106. [

However, the present invention is characterized in that the improvement in the rotation radius of the digital camera among the configurations disclosed in the above-mentioned Japanese Patent No. 0947106 is the most important constitutional feature.

Therefore, the device structure, characteristic and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent No. 0947106, and the structure related to the main features of the present invention will be described in detail at the rear end.

First, as shown in FIG. 1 to FIG. 4, the data processing in the present invention allows a user to feel an image output to a monitor as if he or she is looking directly at an aircraft, The user who uses the digital map can feel the reality and can confirm various aspects of the ground water B so that the user can easily match the ground on which he is located and the digital map.

This is achieved by acquiring a plurality of image images used as the background of the digital map and providing a desired image according to a user's selection. Since the provision of the images is performed on a uniform basis according to a certain condition, You can see the image in realistic way from the desired direction.

In order to secure a video image to be applied to the present invention, a photographing module 110 that rotates in the traveling direction of the aircraft A is required as shown in FIG.

At this time, the photographing module 110 rotates by driving the wide angle rotation module 120 while a plurality of digital cameras 113 are rotatably fixed to the rotation axis 111 via the rotating body 112. Of course, all of the plurality of digital cameras 113 are located at a certain distance about the rotation axis 111.

Subsequently, a plurality of digital cameras 113 are simultaneously photographed.

Therefore, as shown in Figs. 2A to 2C, the digital camera 113, which is facing the ground regardless of where the aircraft A is located with respect to the ground B, continues to shoot the ground .

For reference, since the plurality of digital cameras 113 are arranged in a circular shape along the rotating body 112, a digital camera aimed at the ground as well as a digital camera aiming at the opposite direction of the ground exist at the same time. Therefore, all of the digital cameras 113 constituting the photographing module 110 may simultaneously perform the photographing operation, and in consideration of the efficiency, only the digital camera aiming at the ground may proceed the photographing operation at the same time.

On the other hand, the digital camera 113 determines the shooting time according to the flight information such as the speed and altitude of the aircraft A, and the rotational speed of the rotating body 112 is also determined according to the flight information.

2 and 3, the aircraft A proceeding with the aerial photographing moves in a linear direction over the point of the image image to be photographed. At this time, the operation mode of the photographing module 110 is changed according to the flight information of the aircraft A so that the digital camera 113 can continuously photograph the specific point. This is also described in detail below.

The image processing system according to the present invention includes an image pickup unit 100 mounted on an aircraft A for photographing the ground, an output unit for outputting and utilizing a digital map with a background image of the image picked up by the photographing unit 100 200).

The photographing unit 100 includes the above-described photographing module 110, a wide angle rotation module 120 for determining and rotating the rotation speed of the rotating body 112 according to the operation information, A speed detection module 140 for checking the moving speed of the aircraft A and transmitting the detected speed to the wide angle rotation module 120; A coordinate formation module 160 for confirming GPS coordinate information on a photographing point of a video image and linking to a corresponding file, a file creation module 150 for creating a video image, And a storage module 170 for storing the image information file and coordinate information confirmed by the coordinate confirmation module 160 and linked. Here, the storage module 170 may be a publicly known storage medium such as a hard disk, a floppy disk, a CD, or a USB memory.

The output unit 200 includes a ground structure image confirmation module 210 for classifying only the image of the ground structure by checking the image stored in the storage module 170 and an image editing unit 210 for separating the ground structure image A data storage module 230 for storing the final result of the edited video image through the image editing module 220, and an image editing module 220 for outputting the image image through the monitor, An output module 240 for searching and outputting an image, and a link information DB 250 for storing related link information of the ground structure image among the final images of the image.

Here, the output module 240 includes an image identification unit 241 for confirming an image of a ground structure edited in a layer format by the image editing module 220, an image recognition unit 241 for checking the pixels of the monitor, An image search means 243 for searching a corresponding image image according to the position of the image of the ground structure when the output position of the image image is adjusted by the user, And image output means 244 for outputting the replaced image to the existing image.

FIG. 6 is a view for explaining the operation of the wide angle rotation module according to the present invention, The image which shows the image of the ground structure image is explained with reference to this.

S11; Flight information verification step

The speed sensing module 130 and the altitude checking module 140 configured in the photographing unit 100 of the aircraft A confirm the flight information of the aircraft A. [ Here, the flight information includes the speed and altitude information of the aircraft A, and is connected to the board of the aircraft A in a communicative manner so that the speed and the altitude information can be provided thereto, You can also measure and detect information and collect it. The structure and structure of the speed sensing module 130 for measuring the speed of the aircraft A and the structure and structure of the altitude verifying module 140 for measuring the altitude of the aircraft A are generally well known and common technologies The description of the circuit characteristics and the mechanical structure of the speed sensing module 130 and the altitude checking module 140 will be omitted.

S12; Rotation speed calculation step

The wide angle rotation module 140 checks flight information collected by the speed detection module 130 and the altitude confirmation module 140, and controls the operation of the photographing module 110 based on the information.

More specifically, a plurality of digital cameras 113 radially arranged in a rotating body 112 rotatably fixed about a rotating shaft 111 rotates the rotating speed of the digital camera 113 based on the flying information of the aircraft A, And the photographing period of the digital camera 113 are determined. That is, as described above, in order for the digital camera 113 to take a picture at a specific point on the ground so that continuous shooting can be performed even while the aircraft A is moving, the rotational speed of the rotating body 112 is lower than the rotational speed of the aircraft A Speed and altitude information of the vehicle.

As shown in FIG. 6, for the ground photographing, the altitude and the speed of the aircraft A must be kept constant. In this premise, 'h', which is the altitude of the aircraft A, becomes the radius of the virtual circumference C, and when the aircraft A goes straight at a certain height, the imaginary circumference C is like the wheel of the aircraft A Shape. Therefore, when the arbitrary digital camera 113 photographs the point P1 and the aircraft A moves in the left direction in the state that the aircraft A is positioned in the upper right room of the point "P1" In order to allow another digital camera neighboring the arbitrary digital camera 113 to photograph the point P2 in a state of being located in the room, a straight line distance between the point P1 and the point P2 is set so as to correspond to the point P1 and the point P3 And the linear velocity of the aircraft (A) passing through the points P1 and P2 and the angular velocity with respect to the inner angle of 'θ' of the point P1 and the point P3 should be matched.

Through this condition, the wide angle rotation module 120 calculates the rotation speed of the rotating body 112 and rotates the rotation axis 111 at the calculated rotation speed.

The wide angle rotation module 120 may calculate and process the rotation speed of the rotating body 112 according to the current altitude and the speed of the aircraft A, The altitude and speed of the aircraft (A) may be adjusted accordingly.

S13; Ground shooting steps

A plurality of digital cameras 113 radially arranged along the circumference of the rotating body 112 photographs the ground at regular intervals according to a constant rotation speed of the rotating body 112. Of course, all of the digital cameras 113 installed in the rotating body 112 can simultaneously perform photographing, and only the digital camera 113 aiming at the ground may change the design so that the photographing is performed.

On the other hand, the photographing time point of the digital camera 113 may be when the digital camera 113 correctly targets the P1 or P2 point on the ground in the vertical direction in the room immediately above P1 or P2 as shown in Fig. Therefore, the greater the number of digital cameras 113 arranged at regular intervals around the circumference of the rotating body 112, the shorter the photographing period of the digital camera 113 will be.

For reference, the photographing period of the digital camera 113 is set by the wide angle rotation module 120. That is, the wide angle rotation module 120 calculates and determines the rotation speed of the rotating body 112, and sets the photographing period of the digital camera 113 in accordance with the determined rotation speed.

S14; Steps to check the shooting location

The coordinate confirming module 160 confirms the photographing time point of the digital camera 113 and measures GPS coordinates for the position. That is, when the digital camera 113 operates for photographing, the coordinate confirmation module 160 measures and records the current position.

The coordinate confirmation module 160 for measuring the GPS coordinates may be applied to a conventional GPS measuring device.

S15; Image data storage step

The file forming module 150 links the GPS coordinates measured by the coordinate checking module 160 to the file to store the captured image in a file form in the storage module 170, When searching for a file, the linked GPS coordinates are also searched and confirmed.

S16; Ground Structure Image Identification Step

The ground structure image verification module 210 analyzes the file stored in the storage module 170 and searches for an image of the ground structure included in the image data of the file.

As is well known, a color monitor for outputting an image outputs various types of images that can be identified by assigning colors to pixels arranged densely on the monitor surface. A user viewing the color monitor can select a color Identify images by checking the same specified colors repeatedly and consecutively within the range.

The ground structure image checking module 210 uses this principle. It checks each pixel of a monitor on which a video image is output, searches for pixels arranged in the same or similar color so as to have continuity, Thereby forming a boundary line. Here, the continuity means that pixels designated by the same, similar color are immediately adjacent to each other, and pixels designated by the same, similar color are within a predetermined interval. That is, if pixels designated by the same or similar color are arranged in a line within a certain interval, they are connected to form a boundary line.

On the other hand, if the boundary lines formed in this way are connected in a line to form a closed boundary of one or both ends without forming a closed boundary, the boundary line is regarded as not the boundary of the image of the ground structure.

For reference, since the building is constructed of the same aggregate, the image of the ground structure photographed from the building will be clearly divided into the same color, and the boundary line will be formed along the frame.

S17; Image image editing step

When the image of the ground structure is confirmed by the ground structure image confirmation module 210, the image editing module 220 separately separates the ground structure image as shown in FIG. 7, and synthesizes the image of the ground structure in a separate layer format.

Therefore, the output module 240 can distinguish the ground structure image when outputting a video image, thereby outputting the video image being output to the monitor. The description will be described in detail below.

S18; Edit data storage step

The image image having a plurality of ground structure images independent of the layer format is stored in the data storage module 230.

Meanwhile, the image editing module 220 links the related link information to the image of the ground structure when storing the image image, and stores the link information in the data storage module 230. At this time, the link information is stored in the link information DB 250 and may be data such as the name, location, size, usage, etc. of the corresponding ground structure.

When the link information is linked to the image of the ground structure, the image output means 244 of the output module searches the link information DB 250 for the link information of the image of the ground structure included in the image image, When the user selects the image of the ground structure in the layer format, the image output means 244 recognizes it and outputs the window in which the link information is posted.

For reference, the link information stored in the link information DB 250 may be updated and changed in real time when the content is changed, and the ground structure image independent of the background of the image image may be adjusted and updated after the image change.

FIG. 8 is a flowchart sequentially showing a data processing method according to the present invention. FIG. 9 is a view showing an image of a ground structure photographed by the aerial photographing method according to the present invention, and will be described with reference to FIG.

S21; Digital Map Call Step

In order to use the digital map, the user inputs the keyword for the specific region into the image search means 243 of the output module 240. [ Here, the keyword may be a common word input for searching a map, such as an administrative area name such as an address, a name of a shop or a shopping mall.

For reference, the output module 240 according to the present invention can be manufactured as an independent device together with the data storage module 230, and the manufactured device can be utilized as an apparatus such as a navigation system, And may be used as a server of a map search service.

S22; Image Image Search Step

The image search means 243 searches the data storage module 230 for the associated aerial image based on the keyword.

Meanwhile, the data storage module 230 simultaneously searches for a plurality of image images within a certain range based on a corresponding point of the keyword when searching for a keyword-related image. In other words, in a state in which a point directly related to the keyword is displayed so as to be located at the center 11 of the monitor screen even in a searched image image related to the keyword, 9 (b), it is necessary to search for the neighboring image that is output when it is down. Of course, the neighboring video image at this time should be a ground state viewed from the center 11 of FIG. 9 (a) as viewed from the center 11 of FIG. 9 (b) It should be.

For reference, the retrieved image image may be set with reference points 12, 12 ', 12 "for confirming the output of the image image and its movement. The reference points 12, 12', 12" It may be a separated ground structure image or a setting value different from the ground structure image.

The description will be described below.

S23; Image image output step

The image image retrieved by the image retrieval means 243 is output to the monitor screen as shown in Fig. 9 through the image output means 244. [

S24; Image moving step

The user can move the image image for the purpose of confirming other neighboring points in addition to the image image being output to the monitor. For reference, FIG. 9 is a view sequentially showing a state in which a video image is moved downward. At this time, the movement of the image may be performed by a conventional means through manipulation of a mouse or a keyboard. The movement of the video image according to the present invention is the same as the normal movement method of the image being output to the computer. When moving the image, the reference points 12, 12 ', 12 " We will move together.

S25; Ground Structure Locations Step

The image identification means 241 identifies the image of the ground structure designated in the form of an independent layer and the image tracking means 242 identifies the position of the ground structure image or reference point 12, 12 ', 12 " ≪ / RTI >

Generally, since the output position is determined by the OS that controls the operation of the computer, the image outputted to the monitor is checked for information about the image output controlled by the OS, so that the image of the ground structure in the layer format is output It will be able to confirm whether it is.

S26; Output image replacement output step

The image output means 244 divides the monitor into a plurality of spaces to set the boundaries 20 and the tracking of the image tracking means 242 causes the boundaries 20 to be moved, And outputs the linked neighboring image.

As described above, the image retrieval unit 243 searches the data storage module 230 for a plurality of image images including neighboring image images, and each of the image images is linked to the boundary unit 20 partitioning the monitors, When the image of the ground structure is moved to another boundary, the neighboring image image linked to the boundary is immediately output. That is, the image search means 243 associates the ground structure image or reference points 12, 12 ', 12 "and the center 11 of a plurality of video images searched by the image search means 243, And outputs the image image in which the image of the ground structure is located.

For example, when the identification of the image is proceeded to the set reference points 12, 12 ', 12' ', the image retrieving unit 243 retrieves the corresponding image data from the data storage module 230 (12, 12 ', 12 ") in an image or a point of a ground structure (hereinafter referred to as a " ground structure image ") positioned at the center of the searched image image, 9 (a), the monitor outputting the image image is divided into two boundary portions (12, 12 ', 12' ') 20).

9 (b), if the reference point 12 of the image image output in FIG. 9 (a) moves away from the region where the center 11 is located, And outputs a neighboring image image having a reference point 12 'located in a region in which the center 11 of the monitor is neighboring in a line in the moving direction among the connected neighboring images.

9 (c), the reference point 12 'of FIG. 9 (b) is out of the center 11 of the monitor and, as described above, And a reference point 12 "located in the center 11 of the image.

For reference, in the embodiment shown in FIG. 9, the monitor is divided into three sections by the upper and lower rows. However, it is preferable to divide the monitor into a plurality of sections in order to output real image images. Alternatively, the range of the area where the center 11 is located may be narrowed to delicately track the inflow and outflow of the ground structure image or reference point 12, 12 ', 12 "within the above range.

Since the ground structure images in the independent layer format can be discriminated from each other, it is possible to replace the reference points 12, 12 ', 12 "with ground structure images without setting separate reference points 12, 12' Of course.

As a result, the user can see the image displayed on the monitor as if he / she is looking at the ground on the aircraft, so that the user can enjoy the fun of using the digital map and also can view the side view. It is possible to match figure and numerical map efficiently.

The ground coordinate system 300 includes a floor slab 310 that is installed in the ground.

The floor slab 310 is made of a concrete pouring method and the coordinate base housing 320 is built on the floor slab 310.

In this case, since the battery 330 and the coordinate controller 340 are installed in the coordinate base housing 320, in order to prevent the coordinate base housing 320 from being deformed at the time of construction, In a state in which a cross shape is installed on the wall surface of the housing 320, concrete is poured outwardly to form a slab housing integral structure.

Of course, when the coordinate system housing 320 is installed, the battery 330 and the coordinate controller 340 must be mounted.

In addition, the buckling member 350 is preferably a turnbuckle whose both ends are easily adjusted in spacing.

In addition, a latching protrusion 360 is formed on the inner wall of the coordinate base housing 320 to guide the fixture 400, which will be described later, to be easily installed.

The stopper 550 is in the form of a stop bar configured to be able to rotate while the power generator 600 is rotated.

The reason for restricting the rotation angle of the power generator 600 is to prevent the electric wires connected to the battery 330 from being broken while being twisted.

Meanwhile, as shown in FIG. 12, the power generator 600 includes a power generating housing 610 having a rotating shaft 530 fixed to an upper end thereof.

At this time, the power generating housing 610 has a trumpet shape, the inlet has a large diameter, the outlet has a small diameter, and the inlet and the outlet are curved, and the interior is empty.

Therefore, when the wind introduced through the inlet rotates the rotary vane 640, air discharged through the air hole 680 becomes a kind of promoting means for promoting the maneuvering force.

As described above, the present invention can produce self-power through the power generating housing 610, and obtains the power very efficiently, so that the service life is long.

In addition, when the aircraft A is measured under the control of the controller 340, since the fluid 500 is maximally raised to secure the communication channel smoothly, there is no problem of coordinate confirmation failure.

Moreover, since the reference point is always presented accurately even when the feature is changed, it is very advantageous to image the changed feature by reflecting it on the digital map.

In addition, when the measurement is not performed, since the fluid 500 descends and is accommodated in the fixture 400, ease of maintenance can be ensured.

In some cases, a wind speed sensor may be further provided to control the controller 340 so that the height of the fluid 500 can be automatically controlled according to the intensity of the wind. have.
