Hereinafter, preferred embodiments of the damage analysis support system according to the present invention will be described.
[0027]
<Outline of the system>
As shown in FIG. 1, a damage analysis support system 100 shown in this embodiment includes a CPU (central processing unit) 101, a ROM (Read Only Memory) and a RAM (random-access memory) connected to the CPU 101, and the like. A main memory 102 and an HD (hard disk) 104 connected to the CPU 101 and the main memory 102 through a bidirectional bus 108 are provided.
[0028]
As external devices, an input device such as a keyboard 107 and a mouse 103, a display 106 for displaying various screens (images) used at the time of damage analysis, a printer 105 for printing analysis results, and the like are provided.
[0029]
In addition to the operating system (OS) W, the HD 104 stores an application program such as a damage analysis program S according to the present invention. Under the operating system W, the CPU 101 executes the damage analysis program S. To perform damage analysis.
[0030]
In the HD 104, various databases such as a vehicle type attribute database D1 and a parts database D2 are constructed.
[0031]
<Vehicle model database>
The vehicle type attribute database D1 stores vehicle type specifying data required for specifying a vehicle type, such as a manufacturer name, a vehicle type name, a format, a format designation number, and a category classification number.
A plurality of three-dimensional image data is stored corresponding to each vehicle type.
[0032]
This three-dimensional image data is obtained by assigning polygons mainly to the shape (for example, contour) of the vehicle body and the shape of the parts incorporated in the vehicle body to form a three-dimensional image.
When the damage analysis program is executed, a three-dimensional perspective view of the vehicle body is polygon-drawn (3D graphics) based on the three-dimensional image data and displayed on the display 106.
[0033]
The three-dimensional three-dimensionalization of the vehicle body and parts is manufactured by 3D modeling software or the like. More specifically, a method is used in which, for example, a four-view drawing of a part to be analyzed (for example, a vehicle body) is captured by using a scanner or the like, and polygons made up of planes such as squares and triangles are assigned to the data to approximate the actual shape. It has been.
[0034]
On the other hand, the component database D2 stores work data 30 corresponding to each component (including ASSY) in addition to the component data 20, as shown in FIG.
The component data 20 is composed of data such as an image image 23 of the component, a component name 24, and the like, starting with the component number 22 associated with the vehicle type.
[0035]
Further, the work data 30 corresponds to work items for detaching and replacing the part, and additional work data 31 required for the work, and work index data 32 set in consideration of the work (supplemental work), Work wage data 33 and the like are provided.
[0036]
Note that the work index is an index that indicates the amount of work required for the removal and replacement of the part. By multiplying this work index by the labor rate (work unit price), the work cost required for the removal and attachment of the part is calculated. Is done.
[0037]
Further, in the present embodiment, as shown in FIG. 2, in the work for the assembly (ASSY), the above-mentioned incidental work and work index are set. An index or the like may be associated.
[0038]
In the present embodiment, a management ID 40 is assigned to the component data 20 and the work data 30, and the management ID 40 is used to centrally manage work items (work contents) and parts required for the work. Corresponding to the management ID 40, in this embodiment, damage determination data is set.
[0039]
The damage determination data 50 is data used for analyzing the degree of damage, which will be described in detail later. As shown in FIG. 3, the management ID 40 is the head, the part name 51 corresponding to the management ID 40, and the tertiary of this part. A predetermined polygon number 52 assigned in the original three-dimensionalization and a determination line 53 corresponding to a threshold for selecting a work item corresponding to the degree of damage are provided.
[0040]
Next, the damage analysis program will be described with reference to FIGS.
FIGS. 4 to 10 are setting screens that are appropriately displayed on the display 106 when the damage analysis program is executed. The various screens (inputs) using the input device on the setting screen can be used for the present screen. The damage analysis program can be operated.
FIG. 11 is a flowchart showing the processing steps of the damage analysis program.
[0041]
<Damage analysis program>
First, after starting the damage analysis program, the CPU 101 displays the vehicle type selection screen 200 shown in FIG. 4 on the display 106, and receives the vehicle type selection by the operator on the vehicle type selection screen 200 (S101).
[0042]
The vehicle type selection screen 200 corresponds to an operation screen for specifying the vehicle type to be analyzed. For example, when the pointer P such as a mouse is moved to the manufacturer list 201 on the left side of the screen, the vehicle type name 202, A list of vehicle types 203 and the like is expanded and displayed, and finally, a desired vehicle type can be selected by designation in each column.
[0043]
Subsequently, the CPU 101 starts up a 3D image viewer, reads out three-dimensional image data corresponding to the selected vehicle type from the vehicle type attribute database D1, and displays it on the display 106 together with the initial setting screen 300 (S102).
[0044]
In the initial setting screen 300, the outer shape of the vehicle body is displayed in the center of the screen in order to set (specify) the impact input direction (see FIG. 5). Further, the direction of the vehicle body can be changed as appropriate under the operation of the operator, and the impact input direction can be set by changing the direction.
[0045]
In this embodiment, when changing the direction of the vehicle body, a direction selection field 301 such as “front”, “rear”, “right side”, “left side”, etc. is provided at the upper right of the screen, and the direction can be changed by an operation in the direction selection field. The change operation is accepted.
In addition, when the mouse 103 is clicked on the screen, the vehicle body is sequentially rotated.
[0046]
Then, the operator sets the input direction of impact on the initial setting screen 300. If the damage to the front portion of the vehicle body is described as an example, the input direction of the impact is determined by rotating the vehicle body (image) so that the front portion of the vehicle body faces the front side of the screen.
[0047]
Subsequently, the CPU 101 reads a stereoscopic view corresponding to the direction set as the input direction of the impact from the vehicle attribute data D1 and displays it on the display 106. In addition, the setting of the impact width is accepted in this three-dimensional perspective view (S103).
[0048]
In setting the impact width, an impact width setting screen 400 is displayed on the display 106 (see FIG. 6), and setting points 401 displayed at predetermined intervals on the setting screen 400 are designated by the mouse 103 or the like. The impact width can be specified.
[0049]
In the example of FIG. 6, a plurality of setting points 401 are displayed at intervals of 30 degrees from the right side of the vehicle body to the front and the left side. By specifying at least two of these setting points, the setting points 401 A region sandwiched by 401 is recognized as a damage width. In the example of FIG. 6, an impact is applied with a width of 30 to 60 degrees on the left side of the vehicle body with the vehicle body front being a neutral position (0 degree). Also, in this damage analysis program, the setting items can be easily grasped visually by changing the color of the setting range at the same time as setting the impact width.
[0050]
Subsequently, the CPU 101 receives the setting of the impact width, displays the impact height setting screen 500 on the display 106, and accepts the designation of the impact height by the setting operation on the setting screen 500 (S104). ).
[0051]
In addition, in the impact height setting screen 500, as shown in FIG. 7, a three-dimensional perspective view from an obliquely forward direction in which the overall height of the vehicle body is easily grasped is applied. A plurality of set points 501 are displayed in the vertical direction of the vehicle body, and the impact height is set by clicking the set point 501 located at a desired height with the mouse 103 or the like.
Similarly, in setting the impact height, the installation location can be easily recognized visually by changing the color.
[0052]
Subsequently, the CPU 101 displays an impact force setting screen 600 on the display 106, and accepts designation of impact force on the setting screen 600 (S105).
[0053]
In the impact force setting screen, an impact force designation field 601 for designating an impact force such as “weak”, “medium”, and “strong” is displayed at the upper right of the screen, and setting operations in this impact force designation field 601 are performed. The impact force can be specified by. Below that, an adjustment unit 602 for finely adjusting the impact force is provided. By sliding the operation lever 602 (image) displayed on the adjustment unit 602 with the mouse 103, the impact force is finely adjusted. Adjustment is possible.
[0054]
Further, along with the adjustment of the impact force, the depth of the colored portion corresponding to the damaged range is changed on the screen, and the impact force can be recognized as an image from the change in the depth. In other words, when the entire vehicle body is considered as the analysis target part, the damage range can be accurately grasped by the change in the color of the analysis target part. For example, the damage range can be accurately identified by comparison with the actual vehicle. become.
[0055]
Further, the CPU 101 moves to the subsequent damage analysis process by the operation in the “subtotal” operation field 603 displayed on the impact force setting screen 600 (S106).
[0056]
In this step 106, first, in the set damage range, the parts assembled in the damage range are grasped (S201). In the example shown in the present embodiment, since the damage range extends to the entire front left side, in this damage analysis process, the damage analysis is performed with the front bumper ASSY as the analysis target part. FIG. 12 is a flowchart showing a processing routine of this damage analysis processing.
[0057]
Next, the CPU 101 counts the number of polygons located in the damaged range for the parts group located in the damaged range (S202), and the three-dimensional three-dimensionalization of the counted number of polygons and the analysis target portion. The degree of damage is calculated based on the ratio with the number of polygons assigned at the time (specified number of polygons) (S203). In calculating the damage level, the damage level is quantified (quantified) by executing the following damage analysis logic.
[Expression 1]

[0058]
Subsequently, the CPU 101 refers to the part database D2, reads out the data of the damaged part from the part database, and, along with the thumbnail image 703 of the damaged range, the image image of the damaged part, the part number, and the part name Then, a list of parts prices and the like is displayed on the display 106 as a small plan surface 700 (see FIG. 9) (S107).
[0059]
In addition, below the list 701 of such component numbers and the like, an estimation instruction field 702 for instructing the CPU 101 to estimate is provided, and the estimation process is started by clicking the mouse 103 or the like (S108).
[0060]
In this estimation process, first, the damage determination data of the analysis target part is referred to, the number of polygons counted in the previous step 106 is compared with the determination line corresponding to the front bumper ASSY corresponding to the analysis target part, and the calculated polygons Based on whether the number exceeds the number of polygons set as the determination line, the work item required for this damaged part is selected.
[0061]
An example in which the determination line is set to 50% will be described. In the analysis target portion having the specified polygon number 50000, it is regarded as damage requiring “replacement” when the number of polygons located in the damage range is 25000 or more. In addition, if it is less than 250,000, it is regarded as a damage worthy of “repair required”.
[0062]
Then, the CPU 101 calculates the cost required for repairing the damage based on these analysis results and displays it on the display 106.
More specifically, the wage is estimated for each part in consideration of the incidental work and work index set for the part, and the part cost is added to the wage to calculate the estimated total amount (see FIG. 10). .
[0063]
As described above, in the damage analysis support system shown in the present embodiment, the damage range is specified for the analysis target part that is polygon-drawn (three-dimensional), and the damage state is determined from the number of polygons located in the damage range. Is being analyzed. In other words, in the analysis of damage, the damage state can be accurately quantified only by three-dimensionalizing the analysis target part and specifying the damage range.
[0064]
In addition, in the specification of the damage range, the damage range can be specified based on the three-dimensional image of the analysis target part displayed on the display 106, so that the range specification work is easy and the comparison with the actual vehicle is easy and clear. It is possible to specify the damage range with high accuracy.
[0065]
The above-described embodiment is merely an embodiment, and details thereof can be changed as desired.
For example, in the above embodiment, 3D image data used for damage analysis is stored in advance as vehicle attribute data, but this is not always necessary. For example, each part of an actual vehicle is copied with a digital camera or the like, and the image is subjected to 3D modeling. According to the above technique, three-dimensional three-dimensionalization can be performed to obtain three-dimensional image data necessary for specifying the analysis target portion, and damage can be analyzed based on the three-dimensional image data.
[0066]
In the present embodiment, various processing is performed in one terminal. For example, a vehicle attribute database and a parts database are built on a server on the Internet, and an operator accesses the server. Thus, various information can be obtained.
[0067]
In the above-described embodiment, the front bumper ASSY (part group) is designated as the analysis target part. Of course, damage analysis for individual parts is also possible.
[0068]
