Description

Technology Field

[0001] The present invention relates to a spatial image plotting system, and more specifically, to a spatial image plotting system capable of automatically detecting plotting errors to improve the precision of the image plot. Background Technology

[0003] With the development of computers and software, as well as precision optical instruments and laser measuring instruments, it has become possible to produce digital maps, and related technologies have steadily advanced, leading to a rapid shift from traditional analog map production to digital map production.

[0004] In mapmaking, drawing refers to the work of creating a map of two or three dimensions based on spatial information. With the development of digital output technology, it has recently become possible to create maps of digital images or three-dimensional graphic images, and is therefore also called spatial image drawing, meaning that it is like a real photograph.

[0005] As spatial imagery technology has developed in this way, it has become possible to produce more realistic and precise maps, and it has become easier to update spatial imagery information in response to changes in spatial information.

[0006] With these developments, spatial information is widely utilized today as popular information. As accuracy and update efficiency have significantly improved, it is being widely applied in various fields as useful information with high reliability for utilization.

[0007] However, since the generated images were mostly created manually based on collected information, positional errors between images were inevitable; furthermore, there were limitations to precise drawing, particularly due to differences in resolution, field of view, and scale between the drawn images during the drawing process.

[0008] Conventionally, to correct these drawing errors, operators directly searched for errors and manually corrected them once identified. However, this method of error correction was not only cumbersome but also unreliable in terms of accuracy; furthermore, delays in the process made real-time updating of drawing images virtually impossible, causing significant inconvenience to users.

[0009] The matters described above as background technology are intended solely to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. The problem to be solved

Specific details for implementing the invention

[0031] Hereinafter, the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement it. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0032] To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification.

[0033] In addition, terms or words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0035] FIG. 1 is a drawing showing a draft image of a spatial image drawing system according to an embodiment of the present invention and an image data image collected by a field information collection device, and FIG. 2 is a block diagram illustrating the configuration of a spatial image drawing system capable of automatically searching for drawing errors to improve the precision of the image drawing according to an embodiment of the present invention.

[0036] Referring to FIGS. 1 and 2, the spatial image mapping system according to the present invention is designed to produce an image mapping image (M1) that serves as the basis for a map based on aerial photography, ground photography, and various other information collected at the site, and furthermore, to search for mapping errors in the image mapping image (M1) at the site and correct the errors. To this end, the spatial image mapping system is composed of an image mapping server (200) that produces an image mapping image (M1) based on information collected from the outside and corrects and manages an existing image mapping image (M1) based on the collected information, and a site information collecting device (100) that collects external information and transmits it to the image mapping server (200).

[0037] The components configured in each of the image drawing server (200) and the field information collection device (100) will be explained in more detail.

[0038] The image plotting server (200) is composed of a plotting module (240), a map storage module (210), a checkmark information storage module (260), a search module (220), a mapping module (230), and an error verification module (250). The plotting module (240) produces an image plotting image (M1) by superimposing the absolute coordinate system (AX) after digital image plotting. In digital image plotting, the operator plots ground objects and other ground structures, etc., at corresponding locations in pixel units according to collected information, and the existing images modify their appearance or adjust their positions according to new information. Since the method and technique for producing the image plotting image are already known technologies, a basic description is omitted, except for the new updated technology regarding the present invention.

[0039] The field information collection device (100) is composed of an image generation device (110), a GNSS device (120), a laser scanner (130), a storage module (140), an image classification module (150), a filtering module (151), a direction checking module (160), a check verification module (171), and a controller (170).

[0040] The image generation device (110) captures the front of the moving vehicle (C) and generates an image (IM) of the image data as shown in Figure 1 (b). The image data is collected through continuous shooting at regular intervals.

[0041] The GNSS device (120) measures the GNSS (Global Navigation Satellite System) value of the vehicle (C). Additionally, when a GNSS value designated by a field worker is measured, it transmits a first checking signal. That is, when a field worker selects a specific location, the GNSS value of that location is designated, and the GNSS device (120) transmits a first checking signal when the designated GNSS value is measured while measuring the GNSS value. Since the technology of continuously calculating GNSS received from a satellite in real time is already a known technology, further explanation is omitted.

[0042] The laser scanner (130) measures point-by-point vector values ​​in front of the driving vehicle (C) and classifies valid vector values ​​within the valid range. The valid vector values ​​are explained in detail with reference to the embodiment below.

[0043] The storage module (140) collects and stores the image data, GNSS values, effective vector values, and sample images. Although various storage media can be used for the storage module (140), in this embodiment, an SSD (Solid State Drive) is applied instead of an HDD (Hard Disk Drive) to ensure stability of data storage while driving.

[0044] The image classification module (150) converts the image (IM) of the image data into 3D based on the valid vector value and extracts the road image and structure image in front of the driving vehicle (C) by comparing the constituent image within the valid range of the image (IM) with the sample image through a CNN algorithm. The image classification module (150) accurately extracts and classifies the road image and the structure image according to a CNN algorithm based on deep learning and GPU (Graphic Processing Unit) technology. The image classification module (150) converts the image (IM) of the image data into 3D to realistically represent the actual form of the constituent image, thereby increasing the accuracy of extracting the constituent image through the CNN algorithm. For reference, the image (IM) of the image data contains numerous constituent images, and in particular, the structure image is extracted only from the constituent images of the image data image (IM) that are similar to the sample image. The sample image may be a building, street light, traffic light, roadside tree, fence, signboard, car, mailbox, etc. installed along the roadside.

[0045] The filtering module (151) generates a reference image of a structure with a set position value from the structure image extracted by the image classification module (150), and generates a section image of the road image where a designated color or designated mark is located. Among the structure images, images such as streetlights, street trees, fences, signboards, automobiles, and mailboxes are generally omitted during map production. Therefore, for the omitted images, position values ​​such as GNSS values ​​or drawing coordinate values ​​are not set. On the other hand, for the structure images used for drawing during map production, position values ​​are set. Therefore, among the structure images, images with set position values ​​are classified and generated as reference images. Meanwhile, on the road, the road is painted in a specific color or text is displayed so that drivers can visually recognize child protection zones, bus stops, construction zones, etc. Since the designated color or designated mark is displayed on the road, it is identified in the road image among the image data (IM), and the filtering module (151) classifies and generates a section image of the road image where the designated color or designated mark is located.

[0046] The direction checking module (160) identifies the direction of movement of the field information collecting device (100) based on the change in GNSS values ​​measured by the GNSS device (120), confirms the shooting direction of the image generating device (110), sets a first relative coordinate system of a designated standard within a valid range such that the longitudinal axis direction is parallel to the shooting direction of the image generating device (110), and matches the absolute coordinate system (AX) of the image plotting image (M1) retrieved from the image plotting server (200) according to the GNSS value (120) with the first relative coordinate system of the valid range by overlapping them. The field information collecting device (100) may include a rear image generating device (110') in addition to the front image generating device (110) for shooting the driving vehicle (C). In this case, the image data collected through the shooting of the image generating device (110) consists of front image data and rear image data, and in order to classify the front image data among them, the driving direction of the vehicle (C) must be determined. Since the GNSS value changes along with the movement of the vehicle (C), the direction checking module (160) can determine the approximate direction of movement along with the change in the GNSS value. Furthermore, the direction checking module (160) can analyze the driving attitude of the vehicle (C) through an inertial navigation device (not shown) configured in the field information collecting device (100). Therefore, the direction checking module (160) can accurately determine the shooting direction of the image generating device (110) by analyzing the driving attitude of the vehicle (C) at the time of shooting by the image generating device (110).

[0047] Meanwhile, the direction checking module (160) generates a first relative coordinate system of specified specifications within the valid range and matches it by overlapping it with the absolute coordinate system (AX) of the image plot (M1). Since the image plot (M1) of the present invention is in a 2D format and the size of the valid range and the specifications of the first relative coordinate system are specified, the first relative coordinate system can be displayed on the 2D image plot (M1) based on the position of the vehicle (C). However, as the shooting direction changes according to the driving posture of the vehicle (C), the position of the first relative coordinate system also shows continuous change. However, the image data of the present invention is not a video, and since the first relative coordinate system within the valid range is matched by overlapping it with the absolute coordinate system (AX) of the image plot (M1) whenever it is generated, the change in the shooting direction according to the driving posture of the vehicle (C) does not hinder the setting of the first relative coordinate system.

[0049] FIG. 3 is a schematic diagram illustrating an image with a check mark in a spatial image mapping system according to an embodiment of the present invention, FIG. 4 is a block diagram illustrating the components of a check verification module of a spatial image mapping system according to an embodiment of the present invention, and FIG. 5 is a schematic diagram illustrating an image with a check mark marked on it in a spatial image mapping system according to an embodiment of the present invention.

[0050] Referring to FIGS. 2 to 5, the check verification module (171) according to the present invention is composed of an input / output unit (171a) that receives GNSS values ​​from a GNSS device (120) and communicates with an input / output means that a field worker recognizes an alarm visually or aurally and operates manually, a position confirmation unit (171b), and a marking unit (171c) that marks check marks (CZ1, CZ2) on an image plot (M1).

[0051] When the input / output unit (171a) receives the first checking signal, it alarms through the input / output means (101) and receives the second checking signal generated by operating the input / output means (101). The input / output means (101) may be a speaker for the alarm and a switch for operation by a field worker. When the input / output unit (171a) receives the first checking signal from the GNSS device (120), it outputs an alarm through the input / output means (101) to notify the field worker. The field worker generates the second checking signal by operating the switch of the input / output means (101), and the input / output means (101) transmits the second checking signal to the input / output unit (171a). When a field worker reaches a location corresponding to the GNSS value of the first checking signal at the site, they operate the input / output means (101) to generate the second checking signal, so there may be an error between the GNSS value of the first checking signal and the GNSS value of the second checking signal indicated in the absolute coordinate system (AX) of the image plot (M1). That is, even if the GNSS value measured by the GNSS device (120) in the image plot (M1) is a location point of a specific building, the GNSS value measured by the GNSS device (120) at the said location point at the actual site may be different.

[0052] The position verification unit (171b) checks the GNSS value at which the first checking signal is received and the GNSS value at which the second checking signal is received, respectively, through the GNSS device (120). To explain this more specifically, since the first checking signal is generated by the GNSS value set by the field worker, the GNSS value of the first checking signal can be checked in the image plot (M1) before the driving vehicle (C) reaches the corresponding location. Afterward, when the field worker operates the input / output means (101) to generate the second checking signal, the position verification unit (171b) checks the GNSS value at the corresponding location from the GNSS device (120).

[0053] The marking unit (171c) marks check marks (CZ1, CZ2) of a designated radius centered on the GNSS value confirmed by the position confirmation unit (171b) on the image plot (M1). Accordingly, the check marks (CZ1, CZ2) of the first checking signal and the check marks (CZ1, CZ2) of the second checking signal are marked on the image plot (M1) received from the image plot server (200), and are output through the monitor of the input / output means (101) so that a field worker can visually check them. The check marks (CZ1, CZ2) marked in various places are merged into the image plot (M1) as a layer type and managed.

[0054] The controller (170) processes the first relative coordinate system into a radial second relative coordinate system according to the perspective view of the valid range configured in the image data and overlaps it with the image data, checks the relative coordinate values ​​of the segment image in the second relative coordinate system, compares the positions of the reference image and the segment image based on the second relative coordinate system to check the reference coordinate values ​​of the corresponding reference point in the reference image, and overlaps the segment image with the image drawing image (M1) according to the absolute coordinate values ​​corresponding to the relative coordinate values ​​and reference coordinate values ​​in the absolute coordinate system (AX) matched to the first relative coordinate system, and transmits it to the image drawing server. The operation of the controller (170) is explained in more detail through the following embodiment.

[0055] The image plotting server (200) is composed of a plotting module (240), a map storage module (210), a checkmark information storage module (260), a search module (220), a mapping module (230), and an error checking module (250). The plotting module (240) produces an image plotting image (M1) by superimposing the absolute coordinate system (AX) after digital image plotting. Since the method and technique for producing the image plotting image are already known technologies, further explanation is omitted. The map storage module (210) stores the image plotting image (M1) with the absolute coordinate system (AX) superimposed. There are no special restrictions on the image plotting image (M1) as long as it is superimposed with GNSS coordinates, which are the absolute coordinate system (AX). The check mark information storage module (260) stores the check marks (CZ1, CZ2) of the image plotting image (M1) received from the field information collection device (100) according to the GNSS values. There may be an error between the GNSS values ​​of the first and second check signals that are mutually related. The search module (220) searches for an image plotting image (M1) within a certain range based on the GNSS value of the driving vehicle (C) in the map storage module (210), transmits the image plotting image (M1) to the field information collection device (100), and searches for an image plotting image (M1) marked with check marks (CZ1, CZ2) in the check mark information storage module (260). When the GNSS device (120) of the field information collection device (100) measures a GNSS value, the controller (170) transmits the GNSS value to the image plotting server (200), and the search module (220) searches for the corresponding image plotting image (M1) in the map storage module (210) based on the received GNSS value. The search range of the image plotting image (M1) is not particularly limited, but preferably, the search is performed within a certain radius range centered on the GNSS value. The mapping module (230) receives the image plotting image (M1) in which the layer of the segment image is overlapped, updates the image plotting image (M1), and stores it in the map storage module (210).The mapping module (230) processes the image plotting image (M1) stored in the map storage module (210) to manage and update it. Therefore, when an updated image plotting image (M1) is received from the field information collection device (100), the image plotting image (M1) previously stored in the map storage module (210) is changed to the newly received image plotting image (M1). The mapping module (230) can establish and control a management system for the image plotting image (M1) so that the map storage module (210) classifies, stores, and manages the image plotting image (M1) by version. The error checking module (250) checks the position of the first check mark marked around the GNSS value according to the first checking signal and the second check mark marked around the GNSS value according to the second checking signal, and if an error greater than a reference value is confirmed, executes the drawing module (240) to correct the image drawing (M1), and if only the second check mark is confirmed without the first check mark, outputs the image data of the corresponding section where the second check mark is marked.

[0056] To explain the error verification module (250) in more detail, as described above, the first check mark, which is a check mark centered on the GNSS value according to the first checking signal, is marked by a field worker designating an arbitrary point in the absolute coordinate system (AX) of the image plot (M1) and causing an alarm through the GNSS device (120), so it is marked at the location of the corresponding GNSS value in the image plot (M1). However, the second check mark, which is a check mark centered on the GNSS value according to the second checking signal, is marked by a field worker operating the input / output means (101) to generate the second checking signal when reaching the field location of the first check mark at the site, so there may be an error between the GNSS value of the first check mark and the GNSS value of the second check mark. In order to search for and correct the drawing error of the image plot (M1) caused by the above error, the error verification module (250) executes the drawing module (240). Meanwhile, the case where only the second check mark is confirmed without the first check mark is a case where the field worker, when confirming a field condition different from the image plot (M1), arbitrarily manipulates the input / output means (101) without the first checking signal to output the second checking signal. Accordingly, the image data (IM) of the corresponding field is output so that the drawing worker can check it.

[0058] FIG. 6 is a schematic diagram illustrating a spatial image mapping system according to an embodiment of the present invention classifying a structure image and a road image within an effective range in image data in front of a moving vehicle, FIG. 7 is a schematic diagram illustrating a spatial image mapping system according to an embodiment of the present invention setting an effective range and relative coordinates based on the driving direction of the moving vehicle, and FIG. 8 is a schematic diagram illustrating another embodiment of FIG. 7.

[0059] Referring to FIGS. 1 to 8, the field information collecting device (100) collects an image (IM) of image data as shown in Figure 1 (b) by having the image generating device (110) photograph the front of the moving vehicle (C). Since the image generating device (110) continuously photographs the front of the moving vehicle (C) at regular intervals, the image (IM) of the image data changes continuously as the moving vehicle (C) moves. In addition, the GNSS device (120) measures the GNSS value where the moving vehicle (C) is located, and the laser scanner (130) measures the vector value of the scanning image corresponding to the image (IM) of the image data. The vector value is measured from the laser scanner (130) to points at a distance as well as a distance away. In the present invention, only vector values ​​within the distance range specified, that is, within the valid range (Z1) as shown in FIG. 6 (valid image (CIM)), are classified, and the corresponding vector value is designated as the valid vector value. Ultimately, distant points are deleted from the scanning image, and only the valid vector values ​​of near points (P2, P3, P4) remain in the valid image (CIM). Here, the valid range (Z1) is further limited by the direction checking module (160) confirming the shooting direction of the image generating device (110). To explain more specifically, as shown in FIG. 7, the field information collecting device (100) according to the present invention is configured with a pair of image generating devices (110) to respectively photograph the front and rear of a moving vehicle (C). Here, the shooting angle of the image generating device (110) is limited, and the shooting distance is within a specified distance range. Furthermore, since the field information collecting device (100) according to the present invention utilizes only the front view of the moving vehicle (C), the driving direction of the moving vehicle (C) must be confirmed. Accordingly, the direction checking module (160) identifies the direction of movement of the field information collecting device (100) based on the change in GNSS values ​​measured by the GNSS device (120) and confirms the shooting direction of the image generating device, thereby confirming the valid range among the ranges (Z1, Z2) that a pair of image generating devices (110) shoot, and the range within the specified distance range is confirmed as the valid range (Z1).

[0060] When the image data, GNSS values, and valid vector values ​​are all collected, they are stored in the storage module (140) as a single set. In addition, the storage module (140) stores sample images.

[0061] Meanwhile, the image classification module (150) converts an image (IM) within the valid range (Z1) of the image data into 3D based on valid vector values. Since the valid vector values ​​are 3D format information containing information by distance and color, the image classification module (150) can combine valid vector values ​​within the valid range (Z1) to complete a 3D composition image of a certain shape. In addition, the image classification module (150) extracts the road image (21) and structure images (11, 12) in front of the driving vehicle by comparing the composition image with a sample image based on a CNN algorithm.

[0062] The filtering module (151) generates a reference image (31, 32) from the structure images (11, 12) extracted by the image classification module (150) in which a position value is set. The reference image (31, 32) functions as a reference point for identifying the location of a specific section. Among the various types of structure images (11, 12), the images in which a position value is set are mainly large artificial structures such as buildings; therefore, in this embodiment, the reference image (31, 32) is generally a building. Among the structure images (12), vehicles have mobility and a specific position value is set, so they are excluded from the reference image (31, 32).

[0063] The filtering module (151) generates a section image (41, 42) for the section in the road image (21) where a designated color or designated mark is located. As shown in Figure 3 (b), the child protection zone is marked in red, so the filtering module (151) identifies the corresponding mark within the road image (21) and generates a section image (41, 42). As previously mentioned, the effective vector value of the laser scanner (130) also identifies color, so when a section forming a boundary is generated within the road image (21), that section is considered and generated as a section image (41, 42).

[0064] When the valid range (Z1) is set by confirming the shooting direction of the image generating device (110), the direction checking module (160) sets the first relative coordinate system (G1, G1', G2) of the specified standard, in which the longitudinal direction is parallel to the shooting direction of the image generating device (110), within the valid range (Z1, Z1') in the image plot (M1). As described above, the distance between the shooting angle and the valid vector value of the image generating device (110) is already specified, and the specifications of the first relative coordinate system (G1, G1', G2) are also specified. Since the GNSS value and driving attitude of the driving vehicle (C) have all been confirmed, the direction checking module (160) can merge the layer of the first relative coordinate system (G1, G1', G2) into the image plot (M1) transmitted from the image plot server (200) corresponding to the GNSS value. For reference, the above vertical axis corresponds to the Y-axis in the first relative coordinate system (G1, G1', G2), and the horizontal axis intersects the above vertical axis perpendicularly and forms the X-axis.

[0065] In this embodiment, Figure 7(a) illustrates the first relative coordinate system (G1) set across the entire valid range (Z1), Figure 7(b) illustrates the first relative coordinate system (G2) set only on the road image (21) within the valid range (Z1), and Figure 8 illustrates the first relative coordinate system (G1') set in the valid range (Z1') when the driving direction and driving posture of the driving vehicle (C) change. In the following embodiment, the first relative coordinate system (G2) set on the road image (21) will be explained.

[0066] When the first relative coordinate system (G2) is set, the direction checking module (160) matches the absolute coordinate system (AX) of the image plotting image (M1) retrieved from the image plotting server (200) according to the GNSS value and the first relative coordinate system (G2) of the valid range (Z1) by overlapping them. The overlap of the absolute coordinate system (AX) and the first relative coordinate system (G2) is intended to define the relationship between the absolute coordinate system (AX) and the first relative coordinate system (G2). The absolute coordinate system (AX) and the first relative coordinate system (G2), which form a certain standard, have intersection points that are repeated in a certain manner, and this repetition can be expressed through mathematical formulas. Accordingly, the direction checking module (160) matches the absolute coordinate system (AX) and the first relative coordinate system (G2) by mutually formulating them through superposition, and thereby converts the coordinate values ​​of the first relative coordinate system (G2) into GNSS values ​​of the absolute coordinate system (AX).

[0067] When the direction checking module (160) generates a relationship by overlapping the valid range (Z1) with the absolute coordinate system (AX) of the corresponding image drawing (M1), the controller (170) processes the first relative coordinate system (G2) into a radial second relative coordinate system (G3) according to the perspective view of the valid range (Z1) configured in the valid image (CIM1) of the image data as shown in figure (a) of FIG. 9 and overlaps it with the valid image (CIM). Since the spacing between axes and the angle of inclination of the second relative coordinate system (G3), which appears as a radial form, are based on the first relative coordinate system (G2) of the specified standard, the second relative coordinate system (G3) is always positioned at a constant location in the effective image (CIM) regardless of the driving direction, driving posture, and driving location of the driving vehicle (C), provided that the specifications of the image generating device (110), the laser scanner (130), and the first relative coordinate system (G2) are constant.

[0069] FIGS. 9 and 10 are schematic diagrams illustrating how a spatial image mapping system according to an embodiment of the present invention identifies a reference image and a segment image based on a second relative coordinate system in image data and specifies relative coordinate values ​​and reference coordinate values, and FIG. 11 is a schematic diagram illustrating how a spatial image mapping system according to an embodiment of the present invention overlaps a segment image with an image mapping image.

[0070] Referring to FIG. 2 and FIG. 7 through 11, the controller (170) checks the relative coordinate values ​​of the segment images (41, 42) in the second relative coordinate system (G3). Since the segment images (41, 42) displayed based on the second relative coordinate system (G3) have a plurality of boundary points (a1 to a4; hereinafter 'a') configured according to their own shape, the relative coordinate values ​​of the corresponding boundary points (a) can be checked in the second relative coordinate system (G3). In addition, the controller (170) compares the positions of the reference images (31, 32) and the segment images (41, 42) based on the second relative coordinate system (G3), searches for a position within the reference images (31, 32) corresponding to the segment images (41, 42), designates it as a reference point (b1, b2; hereinafter 'b'), and checks the reference coordinate values ​​of the corresponding reference point (b). In this embodiment, the reference point (b) is a position facing the boundary point (a) of the segment image (41, 42) in the reference image (31, 32) as shown in FIG. 9. When the reference point (b) is identified, the controller (170) checks the reference coordinate value of the reference point (b) through the second relative coordinate system (G3).

[0071] Meanwhile, the driving vehicle (C) equipped with the field information collection device (100) moves, and the image generation device (110) and the laser scanner (130) collect and edit the image data (IM), scanning image, and valid image (CIM) in front of the driving vehicle (C) as the driving vehicle (C) moves. Therefore, the boundary point (a) of each reference image (31, 32) and section image (41, 42) generated by the filtering module (151) and the image classification module (150) may have an error depending on the valid image (CIM1, CIM2) as shown in FIG. 9, and the reference point (b) within the reference image (31, 32) corresponding to the boundary point (a) may also have an error depending on the valid image (CIM1, CIM2). Of course, if accurate image collection is achieved, the boundary point (a) and the reference point (b) are identical regardless of the valid image (CIM1, CIM2). Therefore, it is desirable for the controller (170) to correct the error according to the specified rule and unify it.

[0072] The controller (170) overlaps the layers (51, 52) of the segment image on the image plotting image (M1) according to the absolute coordinate values ​​corresponding to the relative coordinate values ​​and reference coordinate values ​​in the absolute coordinate system (AX) matched to the first relative coordinate system (G2), marks a check mark, and transmits it to the image plotting server (200). Since the second relative coordinate system (G3) will only modify the form of the first relative coordinate system (G2) so that it can be displayed on the valid image (CIM), the relative coordinate values ​​of the boundary point (a) and the reference coordinate values ​​of the reference point (b) confirmed in the second relative coordinate system (G3) are identical to those of the first relative coordinate system (G2). Therefore, the controller (170) can convert the relative coordinate values ​​and reference coordinate values ​​into absolute coordinate values, respectively, through a relationship equation for matching the first relative coordinate system (G2) and the absolute coordinate system (AX). When the reference coordinate values ​​and relative coordinate values ​​are converted into absolute coordinate values, the controller (170) overlaps the layers (51, 52) of the segment image with the image plot (M1) according to the absolute coordinate values ​​to create a new image plot (M2) as shown in drawing (b) of FIG. 11. As previously described, the segment image (41, 42) identified in the valid image (CIM) and partitioned by the boundary point (a) in the second relative coordinate system (G3) can be separated into layers (51, 52) as shown in FIG. 10. The separated layers (51, 52) are transformed based on the first relative coordinate system (G3), and the relative coordinate values ​​of the boundary points of the layers (51, 52) are converted into the corresponding absolute coordinate values. Accordingly, the controller (170) overlaps the layers (51, 52) with the image plot (M1) according to the absolute coordinate values, converts the existing image plot (M1) into an upgraded new image plot (M2), and transmits it to the image plot server (200).

[0073] The mapping module (230) of the image drawing server (200) that receives the new image drawing image (M2) updates the map storage module (210), and compares the first checkmark and the second checkmark to check for and correct drawing errors.

[0075] FIG. 12 is a drawing showing the installation of a field information collection device according to an embodiment of the present invention, and FIG. 13 is a drawing showing the interior of an installation support unit according to an embodiment of the present invention.

[0076] As described above, the field information collecting device (100) further comprises an installation support unit (300) mounted on the upper part of a driving vehicle (C), an installation coupling plate (500) coupled to the upper part of the installation support unit (300), a plurality of radiation support members (530) coupled to the upper part of the installation coupling plate (500), a heat radiation plate (520) coupled to the upper part of the radiation support members (530), a heat transfer support member (400) coupled to the upper part of the heat radiation plate (520), and a heat transfer plate (510) coupled to the upper part of the heat transfer support member (400), wherein an image generating device (110) is coupled to the upper part thereof.

[0077] When the heat transfer plate (510) is arranged transversely on the upper part of the heat transfer support (400) and the heat radiating plate (520) is arranged transversely on the lower part of the heat transfer support (400), the heat generated in the image generating device (110) is released to the outside through the heat transfer plate (510), the heat transfer support (400), and the heat radiating plate (520).

[0078] The above plurality of radiation supports (530) are arranged vertically between the heat radiating plate (520) and the installation coupling plate (500), and a space is formed between the heat radiating plate (520) and the installation coupling plate (500) by the plurality of radiation supports (530) so that heat can be smoothly emitted to the outside.

[0079] The above-mentioned installation support unit (300) is positioned at the bottom of the image generating device (110) and comprises an installation support case (310) with an empty interior, an upper and lower adjustment part (320), a pair of left and right fixing parts (330), and a pair of fixing supplementary parts (340).

[0080] The above-described vertical adjustment unit (320) is coupled to the center of the inner lower surface of the installation support case (310) and is movable vertically. A pair of supplementary fastening units (321) having a concave groove are coupled to the upper part of the vertical adjustment unit (320).

[0081] The above pair of left and right fixing parts (330) are coupled to both sides of the inner lower surface of the installation support case (310) and are arranged to face each other with the upper and lower adjustment part (320) in between. The pair of left and right fixing parts (330) fix both sides of the installation coupling plate (500).

[0082] The above left and right fixing part (330) includes an up-and-down operating part (331) which is coupled to the inner lower surface of the installation support case (310) so as to be movable up and down, a fixed support part (332) which is spaced apart from the up-and-down operating part (331) and fixedly coupled to the inner lower surface of the installation support case (310), a lower fastening plate (333) which is coupled horizontally to the upper end of the fixed support part (332) and has a plurality of lower fastening teeth (334), and an upper fastening plate (335) which has one end rotatably coupled to the upper end of the up-and-down operating part (331), and a central part rotatably coupled to the upper end of the lower fastening plate (333) and has a plurality of upper fastening teeth (336).

[0083] When the upper and lower operating part (331) moves upward, one end of the upper fastening plate (335) moves upward together, and the other end of the upper fastening plate (335) moves downward, so that the upper fastening tooth (336) and the lower fastening tooth (334) interlock with each other. An installation coupling plate (500) is coupled between the interlocked upper fastening tooth (336) and the lower fastening tooth (334), and accordingly, the image generating device (110) is firmly fixed.

[0084] Conversely, when the upper and lower operating part (331) moves downward, one end of the upper fastening plate (335) moves downward together, and the other end of the upper fastening plate (335) moves upward, thereby releasing the engagement between the upper fastening tooth (336) and the lower fastening tooth (334).

[0085] A left and right fastening plate (337) is coupled to the other end of the upper fastening plate (335) so as to be movable left and right, and a left and right elastic member (338) is coupled between the upper fastening plate (335) and the left and right fastening plate (337) to provide elastic force to the left and right fastening plate (337).

[0086] The above left and right fastening plates (337) support the side portions of both sides of the radiation support (530) to prevent the radiation support (530) from shaking, and thereby prevent the image generating device (110) from shaking. This elastic structure absorbs minute differences in the dimensions of the radiation support (530) and, at the same time, prevents vibrations generated during operation from being transmitted to the image generating device (110), thereby enabling precise operation.

[0087] The above pair of fixed reinforcement parts (340) are provided at the bottom of the installation coupling plate (500) and are linked with the upper and lower adjustment part (320) to perform temporary fixing and position alignment in the pre-fastening stage of the image generating device (110).

[0088] Specifically, the fixed reinforcement member (340) comprises a fixed reinforcement case (341) coupled to the lower part of the installation coupling plate (500), a fixed reinforcement elastic member (342) coupled to the inner side of the fixed reinforcement case (341), a fixed reinforcement rod (343) having one end coupled to the fixed reinforcement elastic member (342) and capable of moving left and right inside the fixed reinforcement case (341), a circular fixed fastening part (344) coupled to the other end of the fixed reinforcement rod (343) and capable of being housed inside the fixed reinforcement case (341) or exposed to the outside, and a temporary fixing part (345) mounted to be movable left and right on the inner lower surface of the fixed reinforcement case (341), having one end protruding to the outside of the fixed reinforcement case (341) and the other end contacting the lower surface of the fixed reinforcement rod (343).

[0089] One side of the temporary fixing part (345) is formed in a rod shape and protrudes outside the fixing support case (341), and the other side of the temporary fixing part (345) is formed in a semicircle shape and can contact and support the lower surface of the fixing support rod (343). The vertical width of one side of the temporary fixing part (345) is relatively smaller than the vertical width of the other side of the temporary fixing part (345).

[0090] The diameter of the fixed fastening part (344) is approximately the same as or relatively slightly smaller than the inner upper and lower width of the fixed supplementary case (341), and when the other side of the temporary fixing part (345) contacts the lower surface of the fixed supplementary rod (343), the fixed supplementary rod (343) is vertically displaced upward and compressed and fixed, so that left and right movement is temporarily stopped and fixed.

[0091] Normally, the above temporary fixing part (345) moves toward the fixed fastening part (344) to contact and support the lower surface of the fixed support rod (343), and the fixed fastening part (344) is maintained in a state of being housed inside the fixed support case (341).

[0092] When the upper and lower adjustment part (320) moves upward and comes into contact with the lower surface of the installation coupling plate (500), the temporary fixing part (345) moves in the opposite direction of the fixing fastening part (344) and is separated from the lower surface of the fixing reinforcement rod (343), and the fixing fastening part (344) is ejected to the outside of the fixing reinforcement case (341) by the elastic force of the fixing reinforcement elastic member (342).

[0093] The externally protruding fixed fastening part (344) is inserted into and fixed to the supplementary fastening part (321) having a concave groove, and the image generating device (110) is fixed to the upper part of the vertical adjustment part (320), and the vertical adjustment part (320) moves downward so that the entire device moves downward. At this time, the vertical adjustment part (320) can adjust the height of the image generating device (110) and simultaneously distribute the load.

[0094] With the image generating device (110) moved downward, a pair of left and right fixing parts (330) are operated to firmly fix both sides of the installation coupling plate (500), and the image generating device (110) is also firmly fixed.

[0095] In this way, the present invention supports the image generating device (110) at multiple points, such as the supplementary fastening part (321) of the upper and lower adjustment part (320), the fixed fastening part (344) of the fixed supplementary part (340), the upper fastening plate (335) and the lower fastening plate (333), and the left and right fastening plates (337), thereby allowing the image generating device (110) to be fixed without shaking. Furthermore, since engagement and disengagement are possible with simple movements, maintenance and replacement work are easy, and the alignment state can be maintained consistently even with external vibrations.

[0097] FIG. 14 is a drawing showing a state in which a heat transfer support member according to an embodiment of the present invention is mounted between a heat transfer plate and a heat radiating plate, FIG. 15 is a drawing schematically showing a heat transfer support member according to an embodiment of the present invention, and FIG. 16 is a drawing schematically showing a first heat transfer member and a second heat transfer member of a heat transfer support member according to an embodiment of the present invention.

[0098] The heat transfer support member (400) according to the present invention is positioned between the heat transfer plate (510) and the heat radiating plate (520) and can elastically press the heat transfer plate (510) in the direction of the image generating device (110) and can perform a cooling function of the image generating device (110).

[0099] The above heat transfer support member (400) comprises a base member (410), an elastic support member (420) disposed inside the base member (410) such that one side contacts the lower base (412) of the base member (410) and the other side contacts the upper base (411) of the base member (410) to elastically support the lower base (412) and the upper base (411), an elastic guide member (430) disposed spaced apart from the elastic support member (420) such that one side is fixed to the lower base (412) and the other side is fixed to the upper base (411), and the one side is inserted into the other side and elastically supported in the inserted state, and a first heat transfer member (440) disposed in the center of the base member (410) such that the upper side contacts the heat transfer plate (510) and the other side is exposed to the outside of the heat radiation plate (520) to transfer heat to the atmosphere, and the It includes a plurality of second heat transfer sections (450) spaced apart from the first heat transfer section (440), with the upper side in contact with the heat transfer plate (510) and the other side exposed to the outside of the heat radiation plate (520) to transfer heat to the atmosphere.

[0100] The base portion (410) is composed of a lower base (412) and an upper base (411), and an elastic support portion (420) and an elastic guide portion (430) are disposed in the internal space between the lower base (412) and the upper base (411).

[0101] The upper base (411) is located on the side in contact with the heat transfer plate (510), and the lower base (412) is located on the upper side of the heat radiating plate (520), and the gap between the lower base (412) and the upper base (411) is adjusted by the elastic force of the elastic support part (420) and the elastic guide part (430).

[0102] The above elastic support member (420) includes a first support base (421) fixed to the lower surface of the upper base (411), an elastic member (422) with its upper portion fixed to the first support base (421), and a second support base (423) fixed to the upper surface of the lower base (412) and connected to the lower portion of the elastic member (422).

[0103] The above elastic member (422) may be composed of a coil spring and is compressed and stretched between the first support base (421) and the second support base (423) to provide elastic force between the lower base (412) and the upper base (411). The elastic support member (420) serves to maintain a constant elastic force so that the heat transfer plate (510) can be pressed against the image generating device (110) with uniform pressure.

[0104] The elastic guide part (430) comprises a guide body (431) fixed to the lower surface of the upper base (411), a lifting guide (432) whose upper end is inserted into a body groove formed in the lower part of the guide body (431) and whose lower end is fixed to the upper surface of the lower base (412), and a guide elastic part (433) disposed inside the body groove to elastically support the upper part of the lifting guide (432).

[0105] The above elastic guide part (430) is spaced apart from the elastic support part (420) and serves to guide the lifting movement of the base part (410). The lifting guide (432) is inserted into the body groove of the guide body (431) and can slide in the up and down direction. It is elastically supported by the guide elastic part (433), enabling stable linear movement without shaking during the lifting movement of the base part (410).

[0106] Accordingly, the elastic guide part (430) provides a uniform elastic force to the heat transfer plate (510) together with the elastic support part (420), while accurately maintaining the lifting direction of the base part (410).

[0107] The first heat transfer section (440) may be formed with a larger contact area with the heat transfer plate (510) than each of the second heat transfer sections (450). The first heat transfer section (440) is positioned in the center of the base section (410) to intensively absorb heat generated in the center of the heat transfer plate (510), and a plurality of second heat transfer sections (450) are spaced apart from the first heat transfer section (440) to disperse and absorb heat generated in the periphery of the heat transfer plate (510). Through this, an even cooling effect can be achieved across the entire heat transfer plate (510).

[0108] The elastic support member (420) and the elastic guide member (430) can elastically press the heat transfer plate (510) in the direction of the image generating device (110). The elastic member (422) of the elastic support member (420) and the guide elastic member (433) of the elastic guide member (430) cooperate to press the base member (410) upward, thereby ensuring that the heat transfer plate (510) adheres uniformly and stably to the image generating device (110). In this process, the elastic guide member (430) guides the vertical movement of the base member (410) so that the heat transfer plate (510) can make surface contact with the image generating device (110) without eccentricity.

[0109] The first heat transfer member (440) penetrates the lower first hole (412a) formed in the lower base (412) and is coupled to the upper first hole (411a) formed in the upper base (411) to make surface contact with the heat transfer plate (510), and the plurality of second heat transfer members (450) penetrate each lower second hole (412b) formed in the lower base (412) and are coupled to each upper second hole (411b) formed in the upper base (411) to make surface contact with the heat transfer plate (510).

[0110] The first heat transfer section (440) may be formed in a solid cylindrical shape, and the second heat transfer section (450) may be formed in a solid plate shape. The first heat transfer section (440) and the second heat transfer section (450) may be formed from a metal material with high thermal conductivity, such as copper or aluminum, and exhibit efficient cooling performance by combining a conduction method through surface contact with the heat transfer plate (510) and a convection method outside the heat radiating plate (520).

[0111] A cylindrical first heat transfer section (440) concentrates and absorbs heat from the heat transfer plate (510) with a wide contact area at the center of the base section (410), and a plurality of plate-shaped second heat transfer sections (450) are spaced apart around the first heat transfer section (440) to disperse and absorb heat from the heat transfer plate (510), thereby maximizing cooling efficiency.

[0112] Effective cooling action can be performed without a separate cooling means by means of the first heat transfer unit (440) and the second heat transfer unit (450) provided in the heat transfer support unit (400). Specifically, the upper side of the first heat transfer unit (440) and the second heat transfer unit (450) is in surface contact with the heat transfer plate (510), so that heat generated from the heat transfer plate (510) is conducted to the first heat transfer unit (440) and the second heat transfer unit (450), and the other side of the first heat transfer unit (440) and the second heat transfer unit (450) is exposed to the outside of the heat radiation plate (520) and comes into contact with the atmosphere, thereby releasing heat to the outside by convection.

[0113] At this time, the cylindrical first heat transfer section (440) intensively absorbs heat from the center of the heat transfer plate (510) at the center of the base section (410), and the plate-shaped multiple second heat transfer sections (450) are spaced apart around the first heat transfer section (440) to disperse and absorb heat from the periphery of the heat transfer plate (510), thereby achieving a uniform cooling effect over the entire heat transfer plate (510).

[0114] In this way, the present invention can prevent malfunction or damage to parts caused by overheating during the operation of the image generating device (110) by a cooling method combining conduction and convection, and can improve the durability and operational stability of the device.

[0115] It will be obvious to those skilled in the art that the invention described above is not limited by the aforementioned embodiments and attached drawings, and that various substitutions, modifications, and changes can be made within the scope of the technical concept of the invention.
