Description

Data processing method for printing the digital image by 3D}

The present invention relates to a data processing method for three-dimensional visualization of each position of a digital aerial photograph.

Digital aerial photographs are widely used as the background of digital maps without any additional drawing. This is because the numerical map based on the live-action is advantageous for the user's map interpretation and location confirmation.

Meanwhile, in order to secure the aerial photographing image, the aircraft directly photographs the ground. Therefore, the photographing pattern of the ground structure placed on the ground according to the photographing position of the aircraft is variously modified as shown in FIG. 1 (image showing the appearance of the ground structure according to the aerial photographing position). For reference, FIG. 1 illustrates how the same building (shown in orange) is expressed according to the photographing position in three rows and three columns, and is output as nine images.

Conventional digital maps based on aerial photographs have applied aerial photographs applied to the background as if the ground structure is as flat as possible. Therefore, even if the user outputs the aerial photographing image to view the numerical map, and then checks the numerical map while moving the output aerial photographing image, the ground structure included in the aerial photographing image is always output in the same plane view only. That is, even if the ground structure moves to the right in the state where a specific ground structure is located in the center of the monitor and the ground structure is moved to the right in the monitor, the plane is output as it is in the center of the monitor. For reference, when the ground is directly viewed from the aircraft, the plane as well as the side of the specific ground structure may be viewed according to the position movement of the aircraft.

Of course, if aerial photographic image with a flat ground image is applied as the background of digital map, visual interference between ground structure and road, ground structure and ground structure is minimized, so the positional relationship between road and ground structure can be clearly confirmed. This is also advantageous for the user to find a way using the numerical map. However, from a user's point of view using the digital map on the ground, it is difficult to match the ground structure with the digital map that cannot normally be seen on the ground, which means that it takes a lot of time for the user to understand the digital map. An improvement was required.

Accordingly, the present invention has been made to solve the above problems, the data processing method for the three-dimensional visualization of each position of the digital aerial photographing image to enhance the user's understanding of the aerial photographing image, and to give a sense of reality Provision is a technical task.

According to an aspect of the present invention,

In the data storage module for storing a plurality of aerial images taken of the same point on the ground, but separates and stores the ground structure image in the aerial image in a separate layer format, the image search means is linked to the keyword entered by the user An aerial photographing image search step of searching an aerial photographing image having a ground structure image;

The image output means comprises: an aerial photographing image output step of dividing a monitor screen into a boundary to determine a range of an area in which a center is located, and outputting an aerial photographing image in which the ground structure image is located within a range of the area;

An image moving step of moving an aerial photographing image by an image output means such that the ground structure image is out of a range of the region;

A ground structure positioning step of the image tracking means tracking the movement of the ground structure image to confirm the deviation and the moving direction of the area; And

The image output means outputs a neighboring aerial photograph image adjacent to the movement direction in accordance with the deviation and movement direction of the ground structure image identified by the image tracking means, and the ground located within the range of the area in the neighbor aerial photograph image. An output image replacement output step of checking the structure image and allowing the image tracking means to track the image;

It is a data processing method for the three-dimensional visualization of each position of the digital aerial photography image including a.

According to the present invention, when moving the aerial photographing image output to the monitor to give the realism as if looking at the ground from the aircraft, the user can effectively feel the reality of the digital map, through which the understanding of the digital map It can increase the effect.

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

2 is a view showing an aerial photography according to the present invention, Figure 3 is an image showing an aerial photography according to the present invention, Figure 4 is a block diagram showing the appearance of a data processing system according to the present invention. , With reference to this.

Data processing method according to the present invention, when the user sees a digital map in the background of the aerial image, the image output on the monitor to give a feeling as if seen directly on the aircraft, the user using the digital map can feel the reality In addition, since the various aspects of the ground (B) can be confirmed, the user can easily achieve a match between the ground and the numerical map where they are located.

This is possible by securing a number of aerial photographs used as the background of the digital map, and providing the desired image according to the user's choice, and this provision is made on a uniform basis under certain conditions. You can see the aerial photography realistically in this desired direction.

As shown in FIG. 2, in order to secure the aerial photographing image applied to the present invention, the photographing module 110 is required to rotate in the direction in which the aircraft A travels. The photographing module 110 rotates by driving the wide-angle rotating module 120 while the plurality of digital cameras 113 are rotatably fixed to the rotating shaft 111 via the rotating body 112. Of course, the plurality of digital cameras 113 are all located at a predetermined distance about the rotation axis 111.

Subsequently, a plurality of digital cameras 113 perform a photographing operation at the same time. Therefore, as shown in Figs. 2 (a) to 2 (c), wherever the aircraft (A) is located relative to the ground (B), the digital camera 113 facing the ground continues to ground. Will shoot.

For reference, since the plurality of digital cameras 113 are disposed in a circle along the rotating body 112, there are digital cameras aiming at the ground as well as digital cameras aiming at opposite directions of the ground. Accordingly, all of the digital cameras 113 constituting the photographing module 110 may proceed with the photographing operation at the same time, or in consideration of efficiency, only the digital camera targeting the ground may proceed with the photographing operation simultaneously.

On the other hand, the digital camera 113, the shooting time is determined according to the navigation information, such as the speed and altitude of the aircraft (A), the rotational speed of the rotating body 112 is also determined according to the navigation information. Description of this will be described in detail below.

Subsequently, as shown in FIG. 2 and FIG. 3, the aircraft A which performs aerial photography carries out photography while moving in the linear direction over the point which becomes the object of an aerial photography image. At this time, the photographing of a specific point is different from the operation of the photographing module 110 according to the flight information of the aircraft (A) so that one designated digital camera 113 can photograph continuously. This is also described in detail below.

The data processing system according to the present invention is mounted on the aircraft (A), the photographing unit 100 for photographing the ground, and an output unit for outputting and utilizing a numerical map based on the aerial photographing image taken by the photographing unit 100 in the background It consists of 200.

The photographing unit 100 checks the altitude of the photographing module 110 and the wide angle rotating module 120 to determine and rotate the rotational speed of the rotating body 112 according to the navigation information, and the aircraft A. The altitude check module 130 to be transmitted to the rotation module 120, the speed detection module 140 to check the moving speed of the aircraft (A) and transmits to the wide-angle rotation module 120, and the photographing module 110 In the file forming module 150 for generating an aerial photographing image as a file, the coordinate checking module 160 for checking the GPS coordinate information on the photographing point of the aerial photographing image and linking to the corresponding file, and the file forming module 150. And a storage module 170 for storing the formed aerial photography image file and coordinate information linked to the coordinate checking module 160. Here, the storage module 170 may be a known and public storage recording medium such as a hard disk, a floppy disk, a CD, or a USB memory.

The output unit 200 checks the aerial photographing image stored in the storage module 170, and separates the ground structure image identification module 210 for classifying only the ground structure image and the classified ground structure image to edit them in an independent layer format. The image editing module 220, the data storage module 230 for storing the final result of the aerial photographing image edited through the image editing module 220, and outputs the aerial photographing image through the monitor, depending on the user's operation And an output module 240 for searching and outputting the aerial photographing image of the location. Here, the output module 240 is an image identifying means 241 for confirming the ground structure image edited in the layer format by the image editing module 220, and the image to check the position of the ground structure image by checking the pixel of the monitor Tracking means 242, image retrieval means 243 for retrieving the corresponding aerial photographing image according to the position of the ground structure image when adjusting the output position of the aerial photographing image by the user, and output position adjustment of the aerial photographing image by the user It is composed of an image output means 244 for checking and replacing the retrieved aerial photographing image with the existing aerial photographing image.

FIG. 5 is a flowchart sequentially illustrating an aerial photographing image collection process for progressing a data processing method according to the present invention, FIG. 6 is a view illustrating an operation of a wide-angle rotating module according to the present invention, and FIG. This is an image showing the image of the ground structure image, which will be described with reference to the image.

S11; Flight Information Confirmation Step

The speed detection module 130 and the altitude check module 140 configured in the photographing unit 100 of the aircraft A check the operation information of the corresponding aircraft A. Here, the navigation information, including the speed and altitude information of the aircraft (A), are connected to each other so as to communicate with the substrate of the aircraft (A) may be provided with the speed and altitude information through this, the corresponding navigation itself You can also measure and sense information and collect it. Since the configuration and structure of the speed detection module 130 for measuring the speed of the aircraft (A), and the configuration and structure of the altitude check module 140 for measuring the altitude of the aircraft (A) is generally known, public technology The description of the circuit characteristics and mechanical structure of the speed detecting module 130 and the altitude checking module 140 will be omitted.

S12; Rotational Speed Computation Step

The wide-angle rotation module 140 checks the navigation information collected by the speed detecting module 130 and the altitude checking module 140, respectively, and controls the driving of the photographing module 110 based on the navigation information.

In more detail, a plurality of digital cameras 113 disposed radially on the rotating body 112 that is rotatably fixed around the rotating shaft 111 has a rotation speed based on the flight information of the aircraft A. And a shooting cycle of the digital camera 113 is determined. That is, as described above, if one digital camera 113 is dedicated to photographing a specific point on the ground so that continuous photographing is performed while the aircraft A is moving, the rotational speed of the rotor 112 is determined by the aircraft A. This should be done in conjunction with speed and altitude information.

As shown in FIG. 6, the altitude and speed of the aircraft A must be kept constant for ground shooting. 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 moves straight to a certain altitude, the virtual circumference C is like the wheel of the aircraft A. It becomes a shape. Therefore, while the aircraft A is located directly above the 'h' altitude of the P1 point, the arbitrary digital camera 113 photographs the point P1, and the aircraft A moves to the left direction and is directly above the 'h' altitude of the P2 point. In order to allow another digital camera adjacent to the arbitrary digital camera 113 to photograph the P2 point while being located in the room, the linear distance between the P1 point and the P2 point is defined by the P1 point and the P3 point of the virtual circumference C. The distance must be matched, and the linear velocity of the aircraft A passing through points P1 and P2 and the angular velocity for 'θ', which is the interior of the points P1 and P3, must match.

Through such a condition, the wide-angle rotation module 120 calculates the rotation speed of the rotating body 112 and rotates the rotation shaft 111 at the rotation speed thus calculated.

For reference, the wide-angle rotation module 120 may post-calculate and process the rotational speed of the rotating body 112 according to the current altitude and speed of the aircraft A, in a state of determining the rotational speed of the rotating body 112. The altitude and speed of the aircraft A may be adjusted accordingly.

S13; Ground shooting stage

A plurality of digital cameras 113 disposed radially along the circumference of the rotating body 112 photographs the ground at a predetermined cycle according to a constant rotational speed of the rotating body 112. Of course, all the digital cameras 113 installed on the rotating body 112 proceeds to shoot at the same time, by changing the design of the digital camera 113 aimed at the ground may be to be taken.

Meanwhile, as illustrated in FIG. 6, the photographing time point of the digital camera 113 may be when the digital camera 113 aims exactly at the P1 or P2 point in the ground in the vertical direction. Therefore, as the number of digital cameras 113 arranged at regular intervals along the circumference of the rotating body 112 increases, the photographing period of the digital cameras 113 becomes shorter.

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 rotational speed of the rotating body 112, and sets the photographing period of the digital camera 113 according to the rotational speed thus determined.

S14; Shooting position checking step

The coordinate checking module 160 checks a photographing time point of the digital camera 113 and measures GPS coordinates of the corresponding position. That is, when the digital camera 113 operates for photographing, the coordinate checking module 160 measures the current position and records it.

Coordinate checking module 160 for measuring the GPS coordinates may be applied to a conventional GPS measuring instrument.

S15; Image data storage step

The file forming module 150 converts the image taken by the digital camera 113 into data and stores it in the file format in the storage module 170, by linking the GPS coordinates measured by the coordinate checking module 160 to the corresponding file. When searching for files, the linked GPS coordinates are also retrieved and confirmed.

S16; Ground structure image verification step

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

As is well known, a color monitor that outputs an image outputs various types of images that can be identified by assigning colors to pixels closely arranged on a monitor surface. Images are identified by checking the same specified color over and over again in a range.

The ground structure image identification module 210 uses this principle to check each pixel of the monitor on which the aerial photographing image is output, search for pixels arranged in the same and similar colors and arranged to have continuity, and then arrange them in a line. Connect to form a boundary. In this case, the continuity means that pixels designated by the same and similar colors are immediately adjacent to each other, and that pixels designated by the same and similar colors are within a predetermined interval range. That is, if pixels designated by the same or similar colors are arranged in a line within a predetermined 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 range without forming a certain range of closed sections, the boundary line is considered to be not a boundary of the ground structure image. For reference, since the building is built with the same aggregate, the ground structure image photographing the building will be clearly distinguished by the same color of the border, and the boundary line will be formed along this border.

S17; Aerial photography image editing stage

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

Therefore, when outputting the aerial photographing image, the output module 240 may identify the ground structure image, and may alternatively output the aerial photographing image being output to the monitor. Description of this will be described in detail below.

S18; Edit data storage step

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

8 is a flowchart sequentially illustrating a data processing method according to the present invention, and FIG. 9 is a view showing the ground structure image photographed by the aerial photographing method according to the present invention.

S21; Digital Map Calling Step

In order to use the numerical map, the user inputs a keyword for a specific region into the image search means 243 of the output module 240. Here, the keyword may be a general word input for a map search, such as an administrative district name such as an address, a name of a store or a shopping mall, and the like.

For reference, the output module 240 according to the present invention may be manufactured as an independent device together with the data storage module 230, and the manufactured device may be used as an apparatus such as a navigation device, and also provided in an Internet portal site. It may be used as a server of the map search service.

S22; Aerial photography image search stage

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

Meanwhile, the data storage module 230 simultaneously searches a plurality of aerial photographed images within a predetermined range based on a corresponding point of the keyword when searching a keyword related aerial photographed image. In other words, even in the aerial photographing image searched for the keyword, the image directly related to the keyword is output to be located at the center 11 of the monitor screen as shown in FIG. 9 is to search for the neighboring aerial photographs output when the down as shown in (b). Of course, the neighboring aerial photographing image at this time should be the ground view as seen from the center 11 of FIG. 9 (a), so that the appearance of the ground structure image 30 also. It should be changed.

For reference, the searched aerial photograph image may be set reference points (12, 12 ', 12 ") for confirming the output and the movement of the aerial photograph image, this reference point (12, 12', 12") is an independent layer It may be a separate ground structure image, or may be a separate setting from the ground structure image.

This will be described again below.

S23; Aerial photographing image output stage

The aerial photographed image retrieved by the image retrieval means 243 is output to the monitor screen via the image output means 244 as shown in FIG.

S24; Image moving step

The user can move the aerial image for the purpose of checking other neighboring points in addition to the aerial image being displayed on the monitor. For reference, FIG. 9 is a diagram sequentially illustrating a state in which the aerial photographed image is moved downward. At this time, the movement of the aerial photographing image may be made by conventional means through manipulation of a mouse or a keyboard. In addition, the movement of the aerial photographing image according to the present invention is the same as the normal movement method of the image being output to the computer, the reference point (12, 12 ', 12 ") and ground structure image set in the aerial photographing image during such image movement Of course it will move together.

S25; Ground structure positioning step

The image identifying means 241 confirms the ground structure image designated in the form of an independent layer, and the image tracking means 242 is the position of the ground structure image or the reference point 12, 12 ′, 12 ″ identified by the image identifying means 241. To track.

In general, the image output to the monitor is determined by the operating system that controls the operation of the computer, so check the information on the image output controlled by the OS to output the ground structure image in the form of a layer to any point of the monitor You will be able to see if it works.

S26; Output image replacement

The image output means 244 divides the monitor into a plurality of spaces to set the boundary part 20, and when a specific ground structure image leaves the boundary part 20 by the tracking of the image tracking means 242, the corresponding boundary part 20 is provided. The neighboring aerial photographs linked with the output are replaced.

As described above, the aerial image captured by the image retrieval means 243 by the data storage module 230 is a plurality of images including neighboring aerial image, which are linked to the boundary 20 partitioning the monitor. When the ground structure image in (20) moves to another boundary portion, the neighboring aerial photograph image linked to the boundary portion is immediately outputted. That is, the ground structure images or reference points 12, 12 ′, 12 ″ of the plurality of aerial photographed images searched by the image search means 243 are connected with the center 11, respectively, and the boundary at which the center 11 is located ( 20) the aerial photography where the above ground structure image is located outputs an unknown image.

For example, in detail, when the aerial photographing image is identified by the set reference points 12, 12 ', and 12 ", the image search means 243 corresponds to the data storage module 230 through the user's keyword input. When a plurality of aerial photographing images are searched, the reference points 12, 12 ', and 12 "are set at ground structure images or points (hereinafter,' ground structure images') located at the center of the searched aerial photographing images, and then the keywords are set. The aerial photographing image having reference points 12, 12 ', and 12 "set in the ground structure image related to the image is output in accordance with the center 11 of the monitor as shown in Fig. 9A. In this case, the aerial photographing image is outputted. Is divided into three zones by two boundaries 20.

On the other hand, as shown in Figure 9 (b) when the aerial photographing image moves downwards, when the reference point 12 of the aerial photographing image output in Figure 9 (a) is out of the area where the center 11 is located, the aerial The neighboring aerial photographed image connected to the photographed image is neighbored in a line along the direction of movement, and the neighboring aerial photographed image having a reference point 12 'positioned in the area where the center 11 of the monitor is located is output.

Subsequently, if the anti-photography image continues to move downward as shown in Fig. 9 (c), the reference point 12 'of Fig. 9 (b) is outside the center 11 region of the monitor, and the monitor as described above. Search for and output another neighboring aerial photograph with a reference point 12 "located in the center 11 region of.

For reference, in the embodiment shown in FIG. 9, although the monitor is divided into three equally divided sections in a vertical line, it is preferable to divide the monitor into a grid in order to output realistic aerial photographs. Alternatively, by narrowing the range in which the center 11 is located, the ingress and departure of the ground structure image or reference point 12, 12 ', 12 "within the range may be delicately tracked.

On the other hand, since the ground structure image of the independent layer format can be identified, respectively, it is possible to replace the reference point (12, 12 ', 12 ") with the ground structure image without setting a separate reference point (12, 12', 12") Of course.

As a result, the user can realistically view the aerial photograph image displayed on the monitor as if they are looking at the ground on an aircraft, thereby increasing the fun of using the digital map and viewing the side view. It can be used efficiently by matching the actual map with the numerical map.
