Description

A spatial image drawing system that can easily extract drawing images from video images without being influenced by the surroundings {IMAGE DRAWING SYSTEM FOR EXTRACTING DRAWING IMAGE FROM IMAGE}

The present invention relates to a spatial image drawing system, and more specifically, to a spatial image drawing system that can easily extract a drawing image from a video image without being affected by the surroundings.

As digital map production becomes possible due to the development of computers and software, precision optical machines, and laser measuring devices, related technologies are steadily advancing, and conventional analog map production is rapidly changing to digital map production.

In map production, drawing refers to the work of drawing a map as a two-dimensional or three-dimensional image based on spatial information. With the development of digital output technology, it has recently become possible to draw a map as a digital image or three-dimensional graphic image. It is also called spatial image painting because it is similar to real life.

As spatial imaging technology has developed in this way, more realistic and precise map production has become possible, and it has become easier to update spatial imaging information according to changes in spatial information.

Due to these developments, spatial information is widely used as popular information today, and as its accuracy and update efficiency have greatly improved, it is widely applied in various fields as useful information with high reliability in its use.

Figure 1 is a diagram showing a general captured image and a drawing image based on it.

As can be seen in Figure 1(a), when photographing the ground at a certain altitude, the sides of ground objects photographed in aerial video images are inevitably visible. Therefore, conventionally, when drawing an image based on such aerial video image, the image of the ground object was depicted in a three-dimensional shape in the same way as the image of the ground object in the aerial video image, as shown in FIG. 1(b).

However, when images of ground objects are depicted in three-dimensional form, they may differ from the actual arrangement of the ground objects or may be depicted and copied in a uniform form that is different from reality, so the final completed drawing image is similar to that of the aerial video image. A problem arose where it was expressed differently than it appeared. In addition, as images of ground objects are depicted in a three-dimensional shape, a problem has arisen in which it becomes difficult for users to understand the drawing images.

To solve this problem, when producing a drawing image, only a flat image of the ground object was shown, as shown in Figure 1(c), so that the ground object could be as identical as possible to the actual arrangement.

However, the drawing image shown in Figure 1(c) requires the drawing worker to check the aerial video image and then manipulate the drawing machine one by one to draw or copy the flat image of the ground object, so there was a problem in that the drawing work became more manual and cumbersome.

Hereinafter, based on the attached drawings, the present invention will be described in detail so that those skilled in the art can easily practice it. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

In order to clearly explain the present invention, parts that are not relevant to the description are omitted, and identical or similar components are assigned the same reference numerals throughout the specification.

In addition, terms or words used in this specification and patent claims should not be construed as limited to their usual or dictionary meanings, and the inventor must appropriately use the concept of terms to explain his or her invention in the best way. It must be interpreted as meaning and concept consistent with the technical idea of the present invention based on the principle of definability.

Figure 2 is a block diagram showing the overall configuration of a spatial image drawing system that can easily extract a drawing image from a video image without being influenced by the surroundings according to an embodiment of the present invention.

As shown, the spatial image drawing system according to the present invention consists of a drawing device 100 and a storage device 200.

The drawing machine 100 outputs a photographed image and a drawing image of the same point through a pair of input and output means 121 and 122, allowing the drawing worker to effectively carry out the drawing work.

In general, the captured image is output to the input/output means 121 located at the top, and the drawing image created based on the captured image can be output to the input/output means 122 located at the bottom. Conversely, the captured image and the drawing image are output to the input/output means 122 located at the bottom. You can also have it printed. In addition, drawing work can be performed based on the captured image, so the captured image is output to all input/output means 121 and 122, and a drawing image can be displayed based on the captured image in one of them. .

Subsequently, the storage device 200 is composed of a captured image DB 210 that stores captured images, and a drawing image DB 220 that stores painted images. Captured images are aerial images, and image information such as location and magnification is linked and stored. A drawing image is a ground image completed by performing drawing work based on a captured image. The magnification between images as well as the shape of the ground object image for the boundary are integrated so that the boundary between neighboring drawing images is created naturally.

The storage device 200 may be integrated with the fuse 100 or may be separate from it.

The fuse 100 further includes a control means 110 linked to the input/output means 121 and 122. The input/output means 121 and 122 not only output captured images and drawing images as described above, but also input various input values. The input value may be entered by the drawing worker touching the screen, or may be entered through a separate input device. For the screen touch method, known and common touch screen technology can be applied, and for the input device method, technologies such as keyboards and joysticks can be applied.

Subsequently, the control means 110 outputs the captured image and the drawing image through the input/output means 121 and 122 according to the input value, stores the captured image and the drawing image in the storage device 200, and Allows images and drawing images to be newly edited. The control means 110 for this includes an image analysis module 111, a boundary confirmation module 112, a correction module 113, a drawing module 114, and an image processing module 115.

The image analysis module 111 analyzes the color of the captured image and analyzes the overall shape of the captured image.

The boundary confirmation module 112 distinguishes the ground object image from the analyzed captured image and further confirms the boundary inside the ground object image. Since the captured image is captured in color, the boundary confirmation module 112 analyzes the color of the captured image and confirms the ground object image and its boundary based on this. To explain this in more detail, the boundary confirmation module 112 includes a floor boundary confirmation module 112a that confirms the upper boundary line 11 and the lower boundary line 21 in the ground object image (GI; see FIG. 7), and the ground boundary confirmation module 112a. A vertical boundary confirmation module 112b that confirms the vertical boundary lines 31, 32, 33, 34, 35 drawn from the upper boundary line 11 in the water image (GI'; see FIG. 8), and a ground object image (GI, It consists of a shadow confirmation module 112c that checks the shadow of (GI').

The configuration of the floor boundary confirmation module 112a, vertical boundary confirmation module 112b, and shadow confirmation module 112c is described in detail below along with the operation description.

The correction module 113 edits images of ground objects with confirmed boundaries. Through the boundary confirmation, the ground object image is distinguished from the surrounding background as well as the plane and the side, so the correction module 113 distinguishes the plane image and the side image and finally places the plane image in its proper position.

The drawing module 114 completes the drawing image by automatically processing the drawing work on the captured image based on the corrected ground object image. Since the drawing module 114 automatically draws images of ground objects, drawing workers do not need to draw images of ground objects manually, which has the effect of making drawing work faster and easier.

The image processing module 115 processes the captured images taken at various magnifications for each region and inputs information to integrate the captured images. The image processing module 115 processes internal expressions, mutual expressions, and absolute expressions that are usually preceded in order to process the captured image as a background, and completes the uniformity and standardization of multiple captured images through facial expression processing for each. do.

Figure 3 is a flowchart showing the operation sequence of the spatial image drawing system according to an embodiment of the present invention.

S10; Internal expression stage

As is known, interior orientation corrects the distortion inherent in the captured image itself. Images taken of the ground from an aircraft are distorted by various factors such as the characteristics of the camera, atmospheric refraction, and the curvature of the Earth. If there is no distortion in the captured image due to such distortion, the point that should be the coordinates of (x'a,y'a) has the coordinates of (xa,ya) due to the distortion. In this way, internal expression is rearranging each coordinate (xa,ya) of a distorted aerial photograph into new coordinates (x'a,y'a) with the distortion corrected.

In the case of analog aerial photography, for internal expression, the main point of the aerial photograph is aligned with the output center of the fuse and the focal length is adjusted to the scale of the fuse. In other words, this is done by establishing a relationship between the image coordinates scanned from the drawing machine and the aerial photograph coordinates based on the main point. However, the internal expression work for the digital aerial photograph using the fuse 100 is performed through establishing coordinates and editing images based on them. Accordingly, the image processing module 115 performs facial expression processing on the captured images output to the input/output means 121 and 122 through digital editing.

S20; Mutual expression stage

While the internal orientation aims to reproduce the optical environment inside the camera, the external orientation aims to define the positional relationship between the camera and the target object. External facial expression is again composed of relative orientation and absolute orientation depending on its purpose.

The reciprocal expression can be performed after the internal expression has been performed. In addition, mutual expression is performed as part of acquiring the coordinates of the three-dimensional model and simultaneously removing longitudinal parallax for the tie point. A pair of photos with all parallax removed through mutual expression can form a complete three-dimensional model. However, since the three-dimensional model defines the relative relationship between two photos with one photo fixed, the scale and level are not properly aligned and it does not have an accurate similarity with the actual terrain. Therefore, in order to match the three-dimensional model to the actual terrain, a coordinate conversion process is necessary to convert model coordinates, which are three-dimensional virtual coordinates, into object space coordinate system.

For reference, the elements used in mutual expressions take five independent elements among the rotations ω1, ω2, Ψ1, Ψ2, x1, and x2 around each axis of x, y, and z of the left and right projectors.

S30; Absolute facial expression stage

In order to match the similarity between the actual terrain and the image in terms of scale, level, and horizontal position, which were not achieved in the mutual facial expression step (S20), absolute orientation is performed.

When performing an absolute facial expression, at least three ground reference points (e.g., coordinates of facial expression points) must be known, and the number of points required may increase in proportion to the number of three-dimensional models. Therefore, by using aerial triangulation, the time and cost required in the reference point selection and surveying process can be significantly reduced.

Aerial triangulation is performed through reference point surveying. Aerial triangulation is a method of observing the coordinates of countless points on aerial photographs and then converting the coordinates of the countless observed points into absolute or geodetic coordinates using an electronic calculator based on a small number of reference points (or ground reference points).

The internal expression, mutual expression, and absolute expression for the captured image described above are processed by the image processing module 115, and through this, the captured image is standardized and processed to match the scale, level, and horizontal position corresponding to the actual measurement. do.

Since the technology for processing facial expressions of captured images by the image processing module 115 for illustration purposes is a known and common technology in the relevant technical field, detailed descriptions of calculation formulas and laws applied to each facial expression will be omitted here.

S40; painting stage

Drawing work is performed based on the captured image whose facial expression processing has been completed by the image processing module 115.

The video drawing production system according to the present invention modifies the image of the ground object included in the captured image, and the drawing step for this will be described in more detail.

Figure 4 is a flowchart showing the drawing sequence of the spatial image drawing system according to an embodiment of the present invention, and Figure 5 is a diagram showing the first image shown through the spatial image drawing system according to an embodiment of the present invention. , Figure 6 is a diagram showing a second image shown through a spatial image mapping system according to an embodiment of the present invention, and Figure 7 is a diagram showing a spatial image mapping system according to an embodiment of the present invention captured in a captured image. It is a diagram showing a first embodiment of processing an image of a ground object, and Figure 8 is a diagram showing a second embodiment of a spatial image mapping system processing an image of a ground object captured in a photographed image according to an embodiment of the present invention. 9 is a diagram showing a drawing image shown by the spatial image drawing system according to an embodiment of the present invention.

S41; Image shape confirmation step

The image analysis module 111 checks the captured image DB 210 to determine whether there is a captured image with a change in content, and if it is confirmed that there is a captured image with a change in content, the ground object image is displayed at the point where the content changes. Check whether (GI) has been reinforced.

In an embodiment according to the present invention, it is assumed that there is no ground object in the update area (Z) in the image captured before the update of FIG. 5(a), and the same update area (Z) in the image captured after the update of FIG. 6(a) '), it is assumed that newly built ground structures exist.

In order to draw a drawing image containing a ground object image (GI) for a newly identified ground object, the video drawing production system according to the present invention analyzes a photographed image for which facial expression processing has been completed and uses the ground object image (GI) as a different background. distinguish it from To this end, the boundary confirmation module 112 analyzes the color of the captured image output through the input/output means 121 and 122 in pixel units, and through this, first checks the shape of the captured image.

S42; Ground object confirmation step through floor boundary confirmation

Once the shape formed by the captured image is confirmed, the boundary confirmation module 112 analyzes the color arrangement pattern and distinguishes the ground object image from the background.

To explain this in more detail, as shown in FIGS. 6 and 7, the ground image (GI) captured in the captured image exposes not only the planar image 10 but also the side image 20. On the other hand, in general ground objects such as buildings, the lower boundary line 21 in contact with the ground and the upper boundary line 11 in contact with the plane and the side have the same or similar structure. Meanwhile, as shown in FIGS. 6 and 7, the planar image 10 and the side image 20 of the ground object image (GI) show a clear boundary difference due to differences in contrast and actual color. In the end, the floor boundary confirmation module 112a of the boundary confirmation module 112 observes repetition in the upper boundary line 11 and the lower boundary line 21 at a specific point in the process of analyzing the color arrangement pattern of the captured image, The area observed in this way is first estimated using ground images (GI).

Accordingly, in order to confirm the upper boundary line 11 and the lower boundary line 21, the floor boundary confirmation module 112a maintains a pair of boundary lines confirmed through color analysis parallel to a certain ratio or more and one of the boundary lines If it is confirmed that this closed section is formed, the area of the colored area surrounded by the pair of boundary lines is first estimated using the image of the ground object. Here, among a pair of boundary lines, the boundary line forming the closed section is viewed as the upper boundary line (11), and the remaining boundary line is viewed as the lower boundary line (21).

S43; Ground object confirmation stage

The floor boundary confirmation module 112a, which constitutes the boundary confirmation module 112, when one pair of boundary lines identified through color analysis is confirmed to be parallel to a certain ratio or more and one of them forms a closed section, the pair of boundary lines 112a constituting the boundary confirmation module 112 The area of the colored area surrounded by boundary lines is first estimated using the ground object image, but if it is confirmed that one of the pairs forms a closed section while maintaining parallelism below a certain ratio, a boundary confirmation module 112 is configured. The vertical boundary confirmation module 112b is driven to check whether there is an image of a ground object in the corresponding area.

To explain this in more detail, the upper boundary of a ground object corresponds to the rooftop, so the entire object is photographed without interference during aerial photography, but the lower boundary of a ground object is a part that forms a boundary with the ground, so during aerial photography, other neighboring structures (ex; Landscaping, neighboring buildings, etc.) may prevent you from taking pictures. Additionally, the lower boundary of the ground object may not be photographed because it is obscured by the ground object itself, and may also be interfered with by shadows, etc. Ultimately, as shown in FIG. 8, the lower boundary line 21, which is a captured image of the lower boundary, compared to the upper boundary line 11, which is a captured image of the upper boundary, can be maintained parallel to a certain ratio or less, and in this case, the area is Even though it is an image of a ground object, it can be interpreted as not being a ground object.

Meanwhile, as described above, the floor boundary confirmation module 112a, which constitutes the boundary confirmation module 112, maintains a pair of boundary lines identified through color analysis parallel to a certain ratio or more, and one of them forms a closed section. If it is confirmed that it is, the area of the colored area surrounded by the pair of boundary lines is first estimated using the ground object image, and the subsequent process, the contrast confirmation step (S45), is performed.

S44; Verification stage of ground objects through longitudinal boundary confirmation

If the parallel ratio of the lower layer boundary line (21) compared to the upper boundary line (11) confirmed by the floor boundary confirmation module (112a) in the corresponding area within the captured image does not meet the standards for the ground object image, the vertical boundary confirmation module (112b) determines the floor boundary confirmation module (112b). Vertical boundary lines 31, 32, 33, 34, and 35, which are boundary lines corresponding to edge images in the longitudinal direction, are confirmed between the upper boundary line 11 and the lower boundary line 21 confirmed by the boundary confirmation module 112a. Since the area between the upper boundary line 11 and the lower boundary line 21 corresponds to the side image 20 in the ground object image GI', the corresponding vertical boundary lines 31, 32, 33, 34, and 35 are shown in FIG. 8. ) forms a shape that is drawn downward from the vertex of the upper boundary line 11. For reference, confirmation of the vertical boundary lines (31, 32, 33, 34, 35) is done in the same way as the floor boundary confirmation module (112a) extracts the upper boundary line (11) and the lower boundary line (21) from the captured image. The boundary confirmation module 112b checks the difference in contrast and actual color between the upper boundary line 11 and the lower boundary line 21 of the captured image. Here, if the area in question is a ground object image (GI'), the confirmed vertical boundary lines (31, 32, 33) will be drawn from the vertex of the upper boundary line (11).

In the end, the vertical boundary confirmation module 112b extracts the vertical boundary lines (31, 32, 33, 34, 35) between the upper boundary line (11) and the lower boundary line (21), and in addition, the vertical boundary lines (31, 32, 33, If it is confirmed that 34, 35) is drawn from the upper boundary line 11, the corresponding area in the captured image is secondarily estimated using the ground object image.

When the corresponding vertical boundary line is confirmed, the location of the lower boundary of the ground object image is determined as the end of the vertical boundary line.

S45; Contrast check stage

The shadow confirmation module 112c of the boundary confirmation module 112 determines whether a shadow exists by checking the color of the first and second estimated areas using the ground object images (GI, GI'). Since ground objects naturally form shadows due to sunlight, the shadows are naturally captured during aerial photography, and shadow images are naturally formed in the ground object images (GI, GI'). Therefore, the floor boundary confirmation module 112a and vertical boundary confirmation module 112b of the boundary confirmation module 112 confirm the first and second estimated areas with ground object images (GI, GI'), and create shadows that meet the standards. Once the image is confirmed, the final decision is made as a ground object image (GI, GI').

For reference, if an image of a specified color (ex: dark color) is formed in a uniform direction around the first and second estimated areas as ground object images in the captured image, the shadow confirmation module 112c converts the image into a shadow image. Considered. In the same captured image, the shadow image is bound to be formed in the same direction around the image of the ground object, and the color is also bound to be the same dark color, so a standard is input to the shadow confirmation module 112c to distinguish the shadow image. do. Ultimately, the shadow confirmation module 112c checks whether a shadow image exists according to the input criteria, and when the presence of a shadow image is confirmed, it finally determines the first and second estimated areas as the ground object image.

Subsequently, in the area determined by the ground image (GI, GI'), the planar image (10) and the side image (20) are distinguished based on the upper boundary line (11) and the lower boundary line (21).

As described above, only a portion of the lower boundary line 21 is confirmed, while the entire circumference of the upper boundary line 11 is confirmed, so the planar image 10 confirms all of its shapes, and the lower boundary line 21 confirms the entire circumference of the upper boundary line 11. Check the location of the water image (GI, GI').

S46; Correction stage

When the boundary confirmation module 112 determines the ground object image (GI, GI') and the upper boundary line 11 and lower boundary line 21 of the ground object image (GI, GI'), the correction module 113 determines this. Based on this, the position of the plane image (10) of the ground image (GI, GI') is corrected.

As described above, the fact that the side image 20 is exposed to the ground object images (GI, GI') captured in the captured image means that the corresponding ground object images (GI, GI') were photographed at an angle. This means that the planar image 10 of the corresponding ground object image (GI, GI') is out of position. Accordingly, the image drawing production system according to the present invention automatically corrects the planar image 10 so that it can be positioned accurately.

For this purpose, the correction module 113 checks the upper boundary line 11 and the lower boundary line 21 confirmed by the boundary confirmation module 112, and places the planar image 10 surrounded by the upper boundary line 11 on the lower boundary line 21. Move accordingly. The movement of the planar image 10 is output through the input/output means 21 and 22, and through this, the drawing worker prepares for drawing while checking the position of the planar image 10 to be corrected.

S47; image city stage

When the flat image 10 is moved by the correction module 113 so that the upper boundary line 11 matches the corresponding line of the lower boundary line 21, the drawing module 114 shows a finish line along the upper boundary line 11. do. Of course, the finish line can be modified through additional correction by the drawing operator, and through this, a drawing image with an optimized ground object image that is close to the actual image can be completed.

For reference, Figure 9(a) shows a drawing image before updating in which the ground object images (GI, GI') are not confirmed, and Figure 9(b) shows a drawing image after updating in which the corrected ground object image (IM) is confirmed. It shows a drawing image, and the updated drawing image is the result output when the video drawing production system according to the present invention works based on a photographed image of a ground object without separate work by a drawing worker.

S48; Closing stage

As shown in Figure 9(b), the ground object image (IM) modified through the image drawing production system according to the present invention is the planar image 10 moved to the position of the lower boundary line 21, so the original ground object image In (GI, GI'), the section where the flat image (10) existed becomes blank. Therefore, the blank space in question is drawn manually by the drawing artist, referring to the surrounding colors, and the drawing work is completed through this.
