Description

  The present invention relates to an interior renovation cost estimation system in which a customer can calculate interior renovation costs without the assistance of an expert, and in particular, it is possible to calculate the state of remodeling while simulating the actual size ratio of the room. It relates to a possible interior renovation cost estimation system.

  As a conventional estimation system, a housing planning system described in Patent Document 1 and a construction cost estimation method disclosed in Patent Document 2 have been proposed.

  In the housing planning system of Patent Document 1, a floor plan is selected according to the budget of a home building using a multimedia player, and detailed information on each floor plan is entered, so that a housing plan according to the customer's wishes and conditions can be obtained. It is a system that displays on a TV screen.

  In addition, the construction cost estimation method of Patent Document 2 describes an estimation method for calculating a construction cost by selecting a specific type from the types of rooms stored in a computer and inputting the size of each room. Has been.

  Each of these patent documents considers an architectural plan while confirming an image of a building on a television screen or a monitor, and calculates a construction cost.

  On the other hand, Patent Document 3 describes a floor plan stereoscopic display system. In this display system, when the size of a room is selected by painting a grid of semi-tatami mat units displayed on the screen, and a specific room is selected from the types of rooms prepared in advance, the filled part displays the selected room. By switching to, the floor plan creation work becomes easier.

Japanese Patent Laid-Open No. 7-256045 Japanese Patent No. 3366567 Japanese Patent No. 3166514

  The system of Patent Document 1 is a system that automatically determines a budget amount for each room based on the total budget amount and presents a floor plan or the like prepared in advance from this budget amount. Therefore, in this system, although it is possible to calculate the cost uniformly from a floor plan prepared in advance, it is difficult to estimate the renovation cost corresponding to the actual size of the room where you actually live. .

  Also, the estimation method disclosed in Patent Document 2 is a method in which a living room, a kitchen, or the like is selected from previously stored room types, and the construction cost of each room is calculated based on the selected room. Therefore, this estimation method is also limited to a room estimate prepared in advance, and a budget corresponding to the actual dimensions of the room cannot be calculated.

  On the other hand, the floor plan three-dimensional display system described in Patent Document 3 is a system that selects the size of a room by painting a grid displayed on a screen. However, the displayed grid is limited in size such that the minimum unit that can be displayed is a half-tatami unit, and cannot be displayed in accordance with the actual dimensions of the floor, wall, window, etc. of the room. As a result, this floor plan 3D display system cannot be used for refurbishment corresponding to the actual dimensions of the room.

  As described above, it has been difficult for the conventional estimation system and the floor plan display system to support realistic remodeling estimation of a room in which the user actually lives. That is, in an actual room, even if the floor area is the same, indoor dimensions such as the shape of the floor and the height of the wall differ from room to room. In addition, the conditions of the room further change due to the addition of conditions such as the number and size of windows and the positions of pillars. Therefore, as with conventional systems, it is possible to calculate the approximate cost from a floor plan prepared in advance, but it is not possible to simulate the actual room renovation situation, and the actual dimensions of each room. It is also impossible to calculate an estimate corresponding to.

  Therefore, the present invention was created to solve the above-mentioned problems, and it is possible to easily calculate the renovation cost of a room where the user actually lives, and also simulates the layout of furniture installed in this room. The purpose is to provide a system for estimating the cost of indoor renovation.

In order to achieve the above object, the first means in the present invention automatically calculates the refurbishment cost for each room, and constructs a three-dimensional sketch 20 of the actual size ratio based on the image data taken by the digital camera C.

The indoor remodeling estimation system of the second means is a finishing information input for inputting each selection information of flooring and wall materials selected from the finishing material of the catalog information recorded in the three-dimensional processing module. Means 200, a floor plan display means 300 for displaying on the terminal screen 1A a three-dimensional floor plan 20 in which a remodeling pattern is simulated based on information input by the room information input means 100 and the finishing information input means 200, and a floor plan display means And an estimate calculation means 500 for calculating a room renovation cost based on the information displayed in 300.

In the third means, the catalog display means 400 displays articles selected from various catalog information registered in the three-dimensional processing module on the three-dimensional sketch 20 at an actual size ratio.

The catalog display means 400 of the fourth means accesses a catalog providing server in which various catalog information is registered, and an article selected from the various catalog information is displayed on the three-dimensional sketch 20 at an actual size ratio. It is in.

  As in claim 1 of the present invention, the room information input means 100 based on the image of the simple camera C is used to simulate the remodeling pattern on the three-dimensional sketch 20 of the actual size ratio displayed on the terminal screen 1A.

  According to the indoor renovation cost estimation system of the present invention, it is possible to easily calculate the refurbishment cost based on the actual size of the room where the user actually lives, and to simulate the layout of the furniture installed in the room. Realized the purpose of becoming possible.

  An embodiment of the present invention will be described below. The system of the present invention is a system for automatically calculating the renovation cost for each room, and calculates the room renovation cost while simulating the renovation pattern on the three-dimensional sketch 20 of the actual size ratio displayed on the terminal screen 1A. (See FIG. 4).

  FIG. 1 is a schematic diagram showing the configuration of the system of the present invention. In the figure, reference numeral 1 denotes a computer terminal operated by a customer, and the homepage server 3 is accessed from the terminal 1 via the Internet 2, and the homepage server 3 has membership information such as a customer membership number and password. Process. Thereafter, via the automatic estimation server 4 and the room model creation server 5, the estimated amount, a three-dimensional processing module necessary for the estimation, and an LCD plane grid point drawing program are downloaded to the terminal 1.

  The automatic quotation server 4 distributes the three-dimensional processing module to the terminal 1 that the homepage server 3 has confirmed as an authorized customer, and displays the three-dimensional sketch 20 on the terminal screen 1A. This 3D processing module uses a 3D engine viewer for games equipped with an estimation function. As this 3D engine for games, for example, a commercially available game development software called Unity-3D (registered trademark) manufactured by Unity Technologies can be used to create a viewer equipped with an estimation function. In the present invention, this viewer is used as a three-dimensional processing module.

  The three-dimensional processing module downloaded from the automatic quotation server 4 displays a three-dimensional sketch 20 of the actual size ratio on the terminal screen 1A, and simulates the refurbishment pattern. In addition to the three-dimensional sketch 20, a selection screen 10, a dimension input screen 30, a frontage input screen 40, and a position input screen 50 are displayed simultaneously or selectively on the terminal screen 1A.

  This three-dimensional processing module stores various catalog information relating to articles placed in the room, such as floors, walls, finishing materials, lighting equipment, furniture, etc. The terminal 1 that has read the three-dimensional processing module is a stand-alone device. You can make an estimate as many times as you like. Further, the three-dimensional processing module displays a three-dimensional sketch 20 based on the room image taken by the digital camera C. That is, since the customer's room is displayed at the actual size ratio, the three-dimensional sketch 20 is a system that can perform the remodeling simulation extremely realistically based on the layout of the customer's room and the arrangement state of furniture and the like.

  The basic processing means of the system of the present invention is performed by the room information input means 100, the finishing information input means 200, the sketch drawing display means 300, the catalog display means 400, and the estimate calculation means 500 (see FIG. 2). .

  The room information input means 100 determines the floor plan and dimensions of the room displayed on the 3D floor plan 20 on the terminal screen 1A based on the indoor image data taken by the customer with the digital camera C of the actual room to be renovated. This is a means of displaying the floor plan or the actual size ratio.

  The room information input unit 100 employs a camera calibration method in which geometric information of an object in a three-dimensional space is calculated from the image data of the camera C, and the object is reestablished and recognized. Therefore, the room information input means 100 includes a distortion parameter determination step 110, a photographing step 120, a transmission step 130, an image conversion step 140, and a room model display step 150 (see FIG. 6).

  The distortion parameter determination step 110 is a step necessary for removing distortion of the lens of the digital camera C used by the customer. The distortion parameter of the camera C image used for shooting is determined by shooting the calibration grid 34. . In order to photograph the calibration grid 34, the calibration grid 34 is displayed on the terminal screen 1A of the computer, and the terminal screen 1A is photographed (see FIG. 7).

  The calibration grid 34 is displayed by a drawing program for LCD plane grid points downloaded from the room model creation server 5 (see FIG. 8). At this time, if the terminal screen 1A is not a liquid crystal screen, or if the screen size is small, or the like, it is not suitable for photographing the calibration grid 34, the distortion parameter of the camera C can be obtained even if the paper on which the calibration grid 34 is printed in advance. Can be confirmed.

  Then, when the calibration grid 34 is photographed by the digital camera C, the distribution of the distortion error is as shown in FIG. Therefore, when the distortion parameter is calculated from the photographed image data and the error is corrected, the error distribution of the camera image as shown in FIG. 10 is corrected. The camera C uses a digital camera, and may be a compact camera or a portable camera.

  When shooting with the calibration grid 34, as many distortion errors as possible can be corrected by taking a rotating shooting method, that is, shooting from shooting points 33 in multiple directions (see FIG. 11). More specifically, the distortion parameter can be accurately measured by shooting two images from a total of five directions of the front, top, bottom, and left and right (see FIG. 12A). At this time, the camera C needs to rotate 90 degrees clockwise to take two pictures. In addition, the angle at which these four positions are photographed is an angle of 45 degrees with respect to the terminal screen 1A on which the calibration grid 34 is displayed (see (b) in the figure).

  Next, the photographing step 120 is a step of photographing an actual room layout to be refurbished by the digital camera C that has measured the distortion parameter. In this photographing step 120, it is important to photograph the room from a specific direction together with the marking point 32.

  The marking point 32 uses a mark with a predetermined dimension (see FIGS. 13 and 14). When the marking point 32 is pasted on the wall of a desired room and photographed, other dimensions in the room are analyzed relatively from the dimension of the mark (see FIGS. 17 and 18). As the marking point 32, standard A4 paper (FIG. 13) or CD bag (FIG. 14) can be used. That is, the standard A4 paper is 210 × 297 mm, and the CD bag is 125 × 125 mm. Therefore, by installing the marking points 32 with clear dimensions on the wall surface or the like, it becomes possible to calculate the indoor dimensions based on these dimensions. At this time, the four corners are painted with a conspicuous color so that the outer shape of the marking point 32 can be clearly seen. The range of filling the four corners is preferably about 30 to 50 mm each (see FIGS. 13 and 14).

  The marking point 32 is installed by being attached or placed at a predetermined position in the room. The marking point 32 is installed so as to be able to measure the wall 30, the door 31, the window, the height of the room, the furniture 33, or the distance between two characteristic points (see FIGS. 17 and 18). A set of a plurality of photographs taken within two directions of 45 degrees or less and 15 degrees or more with respect to one marking point 32 (see FIG. 15). At this time, the height of the digital camera C is constant and images are taken from a plurality of directions in which the field of view at the time of shooting is gathered (see FIG. 16).

  Next, the transmission step 130 is a step of transmitting the captured image and distortion parameters obtained in the imaging step 120 from the transmission screen 1A to the room model creation server 5 (see FIG. 1). That is, when the image data of the room photographed by the customer and the distortion parameter obtained by photographing the calibration grid 34 are transmitted to the room model creation server 5, the image conversion process 140 is performed in the room model creation server 5.

  This image conversion process 140 performs a three-dimensional measurement of a specific range by a camera calibration method based on indoor image data, and converts the analyzed 3D model data into stereoscopic image data. It is created using dimensional model processing software. That is, a photographic image from two directions taken at a slight angle with respect to the subject is displayed on the same screen, and one point (depending on the image resolution dpi, for example, the upper right corner of the door frame) ) And points on the other photo that seem to be the same. The two points are recognized as the same point on the program. Repeat the work at this point to increase the shape. Using the photographed image with the angle different from that of the point cloud and the lens characteristic value obtained from the calibration, the 3D point is calculated by the calculation formula based on the photographic measurement theory, and the 3D point is displayed on the CAD program. Let Furthermore, if a line segment is defined (wire frame model) and a surface is defined (surface model), a three-dimensional shape can be expressed. Here, a pattern of each part (for example, a wall) is cut out as an electronic image from the photographed image, pasted (mapped) on the corresponding surface, adjusted (rendered), and approximated to the real thing to complete a three-dimensional model. Is.

  The room model display step 150 is a step of downloading three-dimensional data from the room model creation server 5 to the customer's terminal 1 and displaying the three-dimensional sketch 20 of the actual size ratio on the terminal screen 1A. Through this process, the stereoscopic image data converted by the room model creation server 5 is taken into the three-dimensional processing module, and the room layout that the user desires to simulate is displayed on the terminal screen 1A as a stereoscopic image (FIGS. 4 and 4). 14 to 17). By displaying in this way, the remodeling simulation can be performed extremely realistically based on the layout of the customer's room and the arrangement of furniture and the like.

  In addition, although not shown, for example, an item selected from the various catalog information of the furniture maker is accessed from the terminal 1 by accessing the catalog providing server in which various catalog information registered on the homepage of the furniture maker is registered. It is also possible to configure so as to be displayed on the three-dimensional sketch 20 at an actual size ratio.

  The finishing information input means 200 selects a flooring material or a wall finishing material from the catalog information recorded in the storage device. These selections are made by operating the floor material selection item 13 and the wall material selection item 14 on the selection screen 10 described above (see FIG. 5). The finishing material selected by the finishing information input means 200 is reflected on the three-dimensional sketch 20 by the sketch display means 300.

  The floor plan display means 300 displays the three-dimensional floor plan 20 under selected conditions based on the information input by the room information input means 100 and the finishing information input means 200. Therefore, when the finishing material is changed one after another by the finishing information input means 200, the floor material and wall material of the three-dimensional sketch 20 are also changed to the selected finishing material one after another, so that the finishing material can be selected very easily.

  The catalog display means 400 is a means for displaying articles selected from various catalog information of furniture and fixtures registered in the storage device on the three-dimensional sketch 20 at an actual size ratio. For the selection of furniture and the like, the furniture / equipment selection screen 60 is selected from the input selection items 12 on the selection screen 10 (see FIG. 19). The illustrated furniture / equipment selection screen 60 includes a furniture selection button 61 and an equipment selection button 62. When furniture or fixtures registered on the furniture / equipment selection screen 60 are selected, the selected furniture or the like is arranged on the three-dimensional sketch 20 (see FIG. 21).

  Further, the position input screen 50 is selected on the selection screen 10, and the arrangement position of furniture or the like displayed on the position input screen 50 is set (see FIG. 20). The illustrated position input screen 50 shows a slider button-like input display. An X button 51 for inputting a position (X), a Y button 52 for inputting a position (Y), and a position (Z) are input. By operating the Z button 53, the arrangement position of furniture or the like is displayed as a numerical value indicating the distance from the wall surface or the height from the floor surface. Then, along with the change of the numerical value, the arrangement position of the article moves on the three-dimensional sketch 20 (see FIG. 21). Further, a rotation button 54 for rotating the furniture / equipment and a delete button 55 for deleting the furniture / equipment from the three-dimensional sketch 20 are provided.

  The estimate calculation unit 500 is a unit that calculates the room renovation cost based on the room information of the room information input unit 100 and the finishing material information of the finishing information input unit 200. At this time, the purchase cost of newly purchased furniture or the like can also be added. In this case, furniture or the like to be newly purchased can be selected from various catalog information and displayed on the three-dimensional sketch 20 at the actual size ratio by the catalog display means 400 (see FIG. 21).

  The procedure for using the system of the present invention is as follows (see FIG. 3). First, when the homepage server 3 authenticates a predetermined member registration, a 3D processing module is downloaded from the automatic quotation server 4 to the customer's terminal 1, and an LCD plane grid point drawing program is downloaded from the room model creation server 5. The calibration grid 34 is displayed on the terminal screen 1A. When the screen size of the terminal screen 1A is small, or the like, the calibration grid 34 may be printed on paper when it is not suitable for displaying the calibration grid 34.

  Then, the room photographed by the customer using the room information input means 100 is displayed on the three-dimensional sketch 20 at the actual size ratio.

  Furthermore, the finishing material is determined from the floor material selection item 13 and the wall material selection item 14 from the selection screen 10. When these selections are completed, a three-dimensional sketch 20 of the room designated on the terminal screen 1A is displayed (area B).

  Subsequently, the furniture / equipment selection screen 60 is called from the room selection item 11 on the selection screen 10, and furniture and the like are selected. Then, the position of the furniture and the like is adjusted on the position input screen 50. An estimate is calculated by adding the price of furniture or the like to the finishing material of the room model, and the calculation result is obtained as a file and can be printed out as a document.

  In addition, this invention is not limited to the example of illustration, Each structure of this invention can be changed freely in the range which does not change the summary of this invention.

According to the server invention, the 3D floor plan 20 is drawn by the 3D processing module of the game 3D engine stored in the terminal 1 from the home page server 3, so that even after the estimation is completed, the 3D floor plan 20 is virtually displayed in the 3D floor plan 20. It is possible to keep a pet or perform an arrangement simulation of an article to be purchased in the future. It is also possible to calculate the refurbishment cost while operating the three-dimensional sketch 20 in a game-like manner using a controller for a game machine adapted to the game 3D engine.
