Abstract
Description
[Technical Field]
[0001] The present invention relates to an image synthesis device and a program. [Background technology]
[0002] As measures to prevent rocks from falling onto roads and railway tracks, protective fences are installed along the roadside, and protective nets or curtain nets are stretched over slopes (faces) (countermeasures, installation of countermeasure facilities). Soundproofing walls are also installed on the roadside of expressways to reduce noise caused by running vehicles. For details on protective nets, see Patent Document 1.
[0003] When installing protective fences, etc., a preliminary site survey is generally conducted. In the site survey, the type of countermeasure facility is selected (whether to install a protective fence, protective net, or curtain net, etc.), and the location and scope of the countermeasure facility are investigated. Furthermore, the scope of the countermeasure facility is generally determined by repeating units (height is determined by arranging multiple units vertically, and width is determined by arranging multiple units horizontally). In addition to the repetition, the size of the units themselves is also a consideration.
[0004] It is also common to take multiple site photographs and, while looking at them, consider at a later date the type of countermeasure facility, the location and scope of the facility, the number of units, etc. It is also common for discussions to be held while handwriting the scope of the countermeasure facility on printed site photographs, but as multiple discussions and considerations are held between multiple contractors, including the ordering contractor, design contractor, and installer, and even within the contractor, it can take a considerable amount of time to decide on the specifications for the countermeasure facility.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-336720 DISCLOSURE OF THE INVENTION
[0006] The purpose of this invention is to enable easy determination of the type of countermeasure facility, the installation location and scope of the countermeasure facility, the number of units, etc.
[0007] The image synthesis apparatus according to this invention is characterized by comprising: background image display means for displaying a background image stored in a storage device on a display device; composite image display means for displaying a countermeasure facility image including a plurality of unit images composed of a plurality of vertical line images and a plurality of horizontal line images arranged at intervals from each other, superimposed on the background image displayed by the background image display means; and unit image changing means for changing the size of the unit images.
[0008] A composite image is displayed, in which an image of the countermeasure facility is superimposed on a background image. By superimposing the image of the countermeasure facility onto the background image, the position and extent of the countermeasure facility occupying the background image are clearly represented in the composite image. Typically, the background image is a site photograph taken at the site where the countermeasure facility is to be installed.
[0009] A composite image created by overlaying an image of the countermeasure facility onto a background image allows for a simple rendering of the completed countermeasure. According to this invention, for example, the intentions of a client planning to install a countermeasure facility at a site requiring rockfall protection (where, what type, and what size of countermeasure facility is planned) can be easily and accurately communicated to relevant parties in a short time. Stakeholders can visually grasp the client's intentions and understand the client's countermeasure plan early on. It also enables preliminary design prior to on-site visits.
[0010] The countermeasure construction facility image includes a plurality of unit images, each consisting of a plurality of vertical line images spaced apart and a plurality of horizontal line images spaced apart, and the size of these unit images can be changed. The cost required for installing the countermeasure construction facility (especially the cost of materials) can be roughly calculated depending on the number of vertical line images, the number of horizontal line images, or the number of unit images, so the specifications of the countermeasure construction can be considered taking into account the cost required for installing the countermeasure construction facility.
[0011] In one embodiment, the image synthesis device includes a line image density input means for inputting at least one of the degree of density of the vertical line image and the degree of density of the horizontal line image, and the synthesized image display means displays the vertical line image and the horizontal line image having the degree of density input by the line image density input means superimposed on a background image. The denser the vertical line image and the horizontal line image, the smaller the size of the unit image is changed to, and the sparser the vertical line image and the horizontal line image, the larger the size of the unit image is changed to.
[0012] In one embodiment, the image synthesis device includes a countermeasure work facility image selection means for selecting a countermeasure work facility image to be superimposed on a background image from among a plurality of types of countermeasure work facility images, and from among the plurality of types of countermeasure work facility images, a countermeasure work facility image of a type suitable for installation can be used in the synthesis image.
[0013] In another embodiment, the image synthesis device includes an image editing means for editing the size, position, color, transparency, and shape of the countermeasure construction facility image, and the synthesized image display means displays the countermeasure construction facility image with the size, position, color, transparency, and shape changed by the image editing means superimposed on a background image. The installation location and range of the countermeasure construction facility can be displayed in an adjustable and easy-to-understand manner in the synthesized image.
[0014] The present invention also provides a program for causing a computer device to operate as an image synthesis device. [Brief explanation of the drawings]
[0015] [Figure 1] FIG. 1 is a block diagram showing a hardware configuration of an image synthesis device. [Figure 2] 1 is a front view of the image synthesis device, showing a display screen displaying a synthesized image with a protective fence image superimposed thereon. [Figure 3] 10 shows the display screen after editing the safety fence image. [Figure 4] 10 shows the display screen after editing the safety fence image. [Figure 5] 10 shows a display screen displaying a composite image with a protective net image superimposed thereon. [Figure 6] 10 shows the display screen after editing the protective net image. [Figure 7] 1 shows a display screen displaying a composite image with a curtain net image superimposed thereon. [Figure 8] 10 shows the display screen of the curtain net image after editing. [Example]
[0016] 1 is a block diagram showing the hardware configuration of the image synthesis device 10. FIG.
[0017] The image synthesis device 10 is a computer device, and for example, a smartphone, tablet, etc., can be used as the image synthesis device 10. The computer device functions (operates) as the image synthesis device 10 when a dedicated program (image synthesis program) installed on the computer device is executed.
[0018] Image synthesis device 10 is equipped with a CPU (Central Processing Unit) 11 that controls the overall operation. Connected to CPU 11 are an input device 12 that accepts input of characters, symbols, and other inputs for various operations described below, a display device 13 that displays images, characters, etc., a memory 14 that provides a work area and buffer area for programs and data, a communication device 15 that transmits and receives programs and data via a network, a camera 16 that captures images of subjects, and a storage device 17 that stores programs and data. Storage device 17 stores an operating system (OS) program, an image synthesis program for causing a computer device to function as image synthesis device 10, image data, etc.
[0019] Referring to Figure 2, the display screen of the display device 13 occupies most of the front of the image synthesis device 10.
[0020] The image manipulation panel 31 and the image display area (canvas) 32 are displayed on the display screen of the display device 13.
[0021] A composite image G including a background image G1 and an image G2 representing a countermeasure construction facility superimposed thereon is displayed in the image display area 32. FIG. 2 shows image G2 representing a protective fence, which is one of the countermeasure construction facilities. The background image G1 is an image represented by image data stored in the memory 14 or storage device 17 of the image synthesis device 10. The protective fence image G2 is an image represented by image data generated by an image synthesis program. For the background image G1, a site image (for example, an image based on JPEG data) including a slope (embankment) on which a countermeasure construction facility (such as a protective fence, protective net, curtain net, etc.) should be installed is generally used. For the countermeasure construction facility image including the protective fence image G2, image data with configurable transparency, such as png data or gif data, is used.
[0022] The guardrail image G2 is composed of a fence image g1, which is composed of multiple vertical line images V and horizontal line images H arranged at intervals, and a basic image g2 below the fence image g1. The fence image g1 includes a rectangular frame image, multiple vertical line images V arranged within the frame image at a predetermined interval, and multiple horizontal line images H arranged within the frame image at a predetermined interval, and is represented as multiple rectangular unit images U formed by the multiple vertical line images V and multiple horizontal line images H arranged vertically and horizontally. The height (vertical) size of the fence image g1 is represented by the frame image or multiple unit images U arranged vertically, and the horizontal (width) size of the fence image g1 is represented by the frame image or multiple unit images U arranged horizontally. The basic image g2 is represented by a trapezoidal shape whose top edge overlaps the bottom edge of the frame of the fence image g1.
[0023] The composite image G, which is created by overlaying the protective fence image G2 on the background image G1, is a simple drawing of the completed installation of the countermeasure facility. The intentions of the client who is planning to install the countermeasure facility at a site where slope countermeasures are required (where, what type, and what size of countermeasure facility are planned to be installed) can be easily and quickly communicated to the relevant parties. The relevant parties can visually grasp the client's intentions and can understand the client's slope countermeasure plan at an early stage. It also becomes possible to prepare a rough design prior to visiting the site.
[0024] The image manipulation panel 31 includes a camera icon P1, an image icon P2, an additional countermeasure icon P3, a clear icon P4, an output icon P5, and a selection slider P6.
[0025] The camera icon P1 is tapped when capturing an image to be displayed in the image display area 32. When the camera icon P1 is tapped, the camera 16 of the image synthesis device 10 is activated, and the image of the subject captured by the camera 16 is displayed in the image display area 32 (through image). When a shutter button (not shown) provided in the image synthesis device 10 is tapped or pressed, a still image is displayed in the image display area 32 as a background image G1.
[0026] The image icon P2 is tapped when an image represented by image data stored in the storage device 17 of the image synthesis device 10 is to be displayed as the background image G1 in the image display area 32. When the image icon P2 is tapped, the file names of the image data stored in the storage device 17 of the image synthesis device 10 are displayed in a list. When an image file name is tapped, the image represented by the image data identified by the tapped image file name is displayed as the background image G1 in the image display area 32.
[0027] The "Add Countermeasure" icon P3 is tapped when displaying an image of a countermeasure facility overlaid on the background image. In this embodiment, three types of images are available for the countermeasure facility: a protective fence image, a protective net image, and a curtain net image. By tapping the aforementioned "Add Countermeasure" icon P3 and selecting "protective fence" from among the protective fence, protective net, and curtain net, a composite image G, in which the protective fence image G2 is overlaid on the background image G1, is displayed in the image display area 32, as shown in Figure 2.
[0028] The clear icon P4 is tapped when erasing (deleting) the countermeasure construction facility image displayed in the image display area 32.
[0029] The output icon P5 is tapped when image data representing the composite image G is to be stored in the storage device 17 of the image composition device 10.
[0030] The selection slider P6 turns the selection of the countermeasure facility image displayed in the image display area 32 on or off. When "Select" is selected by the selection slider P6, tapping the protective fence image G2 displayed in the image display area 32 selects the protective fence image G2, allowing it to be edited. When the selection is deselected (no selection is made), tapping the protective fence image G2 will move the image of the protective fence image G2 instead of editing it.
[0031] Figure 3 shows the composite image G after two image editing operations, resizing and opacity, have been performed on the guardrail image G2 shown in Figure 2. Resizing is performed by double-tapping one of the four corners of the fence image g1 included in the guardrail image G2 and sliding the double-tapped corner across the display screen. Resizing allows the area to be covered by the guardrail to be changed, and also allows the shape of the guardrail image G2 to be transformed. The guardrail image G2 can be transformed into any rectangular shape, such as a square, rectangle, quadrilateral, trapezoid, or diamond. For the guardrail image G2, transparency can be set for both the fence image g1 and the base image g2. The higher the transparency, the more the background image G1 is visible through the guardrail image G2. The lower the transparency, the less visible the background image G1 becomes. Using an image with configurable transparency as the guardrail image G2 allows the display of a composite image G that does not completely obscure the portion of the background image (i.e., the terrain) that would be covered by the guardrail.
[0032] FIG. 4 shows the image after editing the number of vertical line images V and horizontal line images H (the number of unit images U) of the fence image g1 for the guardrail image G2 shown in FIG.
[0033] As described above, the fence image g1 includes multiple vertical line images V and multiple horizontal line images H arranged at intervals from each other, and includes multiple rectangular unit images U formed by the vertical line images V and horizontal line images H. For example, if you double-tap the fence image g1, as shown in Figure 4, a spacing adjustment panel 33 including a slider 33a will appear on the display screen instead of the image manipulation panel 31. If you slide the slider 33a of the spacing adjustment panel 33 downwards, the number of vertical line images V and horizontal line images H that make up the fence image g1 decreases (the vertical line images V and horizontal line images H become sparser), and the number of rectangular unit images U enclosed by the vertical line images V and horizontal line images H decreases. If you slide the slider 33a of the spacing adjustment panel 33 upwards, the number of both vertical line images V and horizontal line images H that make up the fence image g1 displayed in the image display area 32 increases (the vertical line images V and horizontal line images H become denser), and the number of rectangular unit images U enclosed by the vertical line images V and horizontal line images H increases. Below the slider 33a, a numerical value representing the approximate sum of the number of vertical line images V and horizontal line images H is displayed, and this value changes when the slider 33a is slid. In image editing using the spacing adjustment panel 33, the size and shape of the protective fence image G2 itself do not change, and therefore the size of each unit image U changes.
[0034] The composite image G, created by overlaying the protective fence image G2 onto the background image G1, can be stored in the storage device 17 by tapping the output icon P5, as described above. The image data representing the composite image G can be sent via email, for example, as an email attachment, and shared among those involved in the construction. The composite image G shows the installation location and range of the protective fence, the number of unit images, etc., so the intentions of the client can be easily communicated to the design company, installation company, etc., and the determination of the specifications for the countermeasures can be expedited.
[0035] In image editing, the color of the protective fence image G2 may be changed to any color. Depending on the color of the background image G1, a protective fence image G2 with a color similar to the background image G1 may be overlaid on the background image G1, or a protective fence image G2 with a different color (a conspicuous color) may be overlaid on the background image G1.
[0036] Figure 5 shows an image synthesis device 10 in which a "protective net" has been selected as the countermeasure facility, and a composite image G, in which a protective net image G3 is superimposed on a background image G1, is displayed in the image display area 32.
[0037] The protective net image G3 includes a plurality of vertical line images V and a plurality of horizontal line images H arranged at predetermined intervals from each other within a rectangular frame image, and includes a plurality of rectangular unit images U formed by the plurality of vertical line images V and the plurality of horizontal line images H.
[0038] When the protective net image G3 is double-tapped in the image display area 32, the spacing adjustment panel 34 appears on the display screen. Unlike the spacing adjustment panel 33 that appears when the protective fence image G2 is double-tapped, the spacing adjustment panel 34 that appears when the protective net image G3 is double-tapped includes a vertical line image adjustment slider 34a for adjusting the number of vertical line images V, and a horizontal line image adjustment slider 34b for adjusting the number of horizontal line images H. Sliding the vertical line image adjustment slider 34a up or down increases or decreases the number of vertical line images that make up the protective net image G3 displayed in the image display area 32. Similarly, sliding the horizontal line image adjustment slider 34b up or down increases or decreases the number of horizontal line images that make up the protective net image G3 displayed in the image display area 32. Increasing or decreasing the number of vertical line images V and / or horizontal line images H also increases or decreases the number of unit images U. Below the vertical line image adjustment slider 34a, a numerical value representing the approximate number of vertical line images V is displayed. A numerical value indicating the approximate number of horizontal line images H is displayed below the horizontal line image adjustment slider 34b.
[0039] Figure 6 shows the image display area 32 after sliding the horizontal line image adjustment slider 34b upwards from the state shown in Figure 5. The number of horizontal line images H has increased, and the size of the unit image U has decreased.
[0040] Figure 7 shows an image synthesis device 10 in which a "curtain net" has been selected as the countermeasure facility, and a composite image G, in which a curtain net image G4 is superimposed on a background image G1, is displayed in the image display area 32.
[0041] Curtain net image G4 differs from protective net image G3 in that it depicts a sag 41 at its upper end.
[0042] When a "curtain net" is selected as the countermeasure facility, the number of deflections is selected. Image G4 of the curtain net shown in Figure 7 shows the case when a deflection of "2" is selected.
[0043] The curtain net image G4 also includes a plurality of vertical line images V and a plurality of horizontal line images H arranged at intervals within a rectangular frame image, and a plurality of rectangular unit images U formed by the plurality of vertical line images V and the plurality of horizontal line images H. As with the protective net image G3, the number of vertical line images V and the number of horizontal line images H in the curtain net image G4 can also be adjusted independently.
[0044] By changing the number of deflections, the number of deflections 41 in the curtain net image G4 that constitutes the composite image G changes. Figure 8 shows the composite image G including the curtain net image G4 when the number of deflections "3" is selected. The curtain net image G4 with three deflections 41 is displayed at the top.
[0045] In the above-described embodiment, the image synthesis device 10 was explained using a rockfall prevention measure as an example. However, for example, a composite image can also be created using the image synthesis device 10 by using an image of a highway as the background image and superimposing an image of a sound barrier or soundproof wall to be installed on the side of the highway. Furthermore, a composite image can also be created using the image synthesis device 10 by using an image of a river or coast as the background image and superimposing an image of a waterproof wall or tide barrier to be installed on the riverbank or coastline.
