[Brief explanation of the drawing]

[Figure 6] Figure 6 shows an example of the image displayed in S4 of Figure 2. [Figure 7] Figure 7 is a magnified view of a portion of the image shown in Figure 6. [Figure 8] Figure 8 is a graph where the horizontal axis represents the size of the jig plate and the vertical axis represents the number of areas with a "high" density. [Modes for carrying out the invention]
[0012] Specific embodiments of the present invention will be described below with reference to the respective drawings.
[0013] FIG. 1 is a configuration diagram of a density display device in which a density display program of the present invention is installed. The density display device 1 is composed of, for example, terminals such as a well-known PC (Personal Computer), a tablet, and a smartphone. The density display device 1 includes a microcomputer 2 (hereinafter abbreviated as "μCOM2") that controls the entire density display device 1, and an operation unit 3 and a display unit 4 connected to the μCOM2.
[0014] The μCOM2 operates according to a density display program stored in a storage unit (not shown). The operation unit 3 is composed of, for example, a keyboard, a mouse, a touch panel, etc. The display unit 4 is controlled by the μCOM2.
[0015] Next, the operation of the density display device 1 having the above-described configuration will be described with reference to the flowchart of FIG. 2. The μCOM2 starts operating according to the density display program. The user operates the operation unit 3 to input an image shown in FIG. 3.
[0016] The image shown in FIG. 3 is an image of the wire harness 21 mounted on the jig plate 20 used in the manufacturing process of the wire harness 21. The wire harness 21 is held by a jig 22 provided on the jig plate 20. In the manufacturing process of the wire harness 21, processes such as taping are performed in a state where the wire harness 21 is mounted on the jig plate 20. Although the image shown in FIG. 3 shows only a part of one jig plate 20, actually, an image of the entire one jig plate 20 is input.
[0017] μCOM2 functions as an image acquisition unit and acquires an image input by the user in accordance with the operation unit 3 (S1). Next, μCOM2 functions as an extraction unit and extracts the wire harness 21 and jig 22 from the acquired image (S2). Specifically in S2, as shown in Figure 4, μCOM2 divides the image into multiple areas and extracts the areas corresponding to the wire harness 21 and jig 22 from among the multiple areas.
[0018] In this embodiment, the area is set to, for example, a diameter of 10 mm. In Figure 4, the area shown in black corresponds to the wire harness and jig 22. Note that in Figure 4, the wire harness 21 and jig 22 are extracted from only a portion of the image, but this is to make the comparison with the original image easier to understand; in reality, the wire harness 21 and jig 22 are extracted from the entire image.
[0019] Next, μCOM2 functions as a density calculation unit and calculates the density of wire harnesses 21 for each area indicated by a circle in Figure 4 (S3). In S3, μCOM2 defines a frame 30 centered on an area indicated by a single circle, as shown in Figure 5. In this embodiment, a frame 30 of 90 mm × 90 mm, which is approximately equal to the width of a hand, is defined. Next, μCOM2 determines the number of areas extracted as wire harnesses 21 or jigs 22 within the frame 30.
[0020] In the case shown in Figure 5, the number of areas (black circles) extracted as wire harnesses 21 or jigs 22 in frame 30 is "2". μCOM2 determines the number of areas for the central area to be "2". μCOM2 sets frame 30 for all areas and determines the number of areas extracted as wire harnesses 21 or jigs 22 within frame 30.
[0021] Subsequently, μCOM2 sets the density according to the number of areas extracted as wire harnesses 21 or jigs 22 for each area. μCOM2 sets a higher density the higher the number of areas obtained. Specifically, μCOM2 sets the density to "low" when the number of areas obtained is between 0 and 19. μCOM2 sets the density to "medium" when the number of areas obtained is between 20 and 39. μCOM2 sets the density to "high" when the number of areas obtained is 40 or more.
[0022] Next, μCOM21 functions as a display control unit and displays the number of areas with the same density for each density on the display unit 4, as shown in Figure 6 (S4). μCOM21 also displays an image on the display unit 4 that allows identification of the density for each area (S4), and then terminates the process. In this embodiment, μCOM21 further displays on the display unit 4 the number of areas extracted as wire harness 21 or jig 22, and the total number of areas that make up the image.
[0023] Furthermore, as shown in Figure 7, μCOM21 displays the number of areas extracted as wire harnesses 21 or jigs 22 within the frame 30 for each area.
[0024] According to the embodiment described above, as shown in Figure 6, the number of areas with the same density is displayed for each density level. This shows that the more areas with high density there are, the more difficult it is to manufacture the wire harness 21. Therefore, by quantifying the difficulty of manufacturing the wire harness 21, anyone can easily judge how difficult it is to manufacture the wire harness.
[0025] Furthermore, by calculating the number of areas with the same density for each wire harness 21, a graph can be created, for example, as shown in Figure 8. Figure 8 is a graph created by plotting the number of areas with a "high" density for each wire harness 21, with the horizontal axis representing the area of the jig plate 20 used to create the wire harness 21 and the vertical axis representing the number of areas with a "high" density. By visualizing this graph, it is possible to compare which wire harnesses 21 can have a smaller jig plate 20 and a lower density.
[0026] According to the embodiment described above, as shown in Figure 6, an image of the wire harness 21 placed on the jig plate 20, which allows for the identification of density in each area, is displayed on the display unit 4. This shows that the more areas with high density there are, the more difficult it is to manufacture the wire harness 21. Therefore, by visualizing the difficulty of manufacturing the wire harness 21, anyone can easily determine how difficult it is to manufacture the wire harness.
[0027] According to the embodiment described above, μCOM2 defines a frame 30 centered on the area, determines the number of areas extracted as wire harnesses 21 or jigs 22 within the frame 30, and calculates the density according to the number of areas determined. This makes it possible to calculate the density of the wire harnesses 21 with high accuracy.
[0028] According to the embodiment described above, an image is displayed showing the number of areas extracted as wire harnesses 21 or jigs 22 within the frame 30 for each area. This makes it even easier to determine how difficult it is to manufacture the wire harness 21.
[0029] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.
[0030] The calculation of density is not limited to the embodiments described above. For example, density may be calculated according to the distance from the area to the wire harness 21 or jig 22.
[0031] In the embodiment described above, μCOM2 displayed an image of the wire harness 21 on the jig plate 20, which allows for identification of density, and the number of areas with the same density on the display unit 4, but it is not limited to this. μCOM2 may display only one of these.
[0032] In the embodiment described above, μCOM2 identified the density by the pattern of the area, but it is not limited to this. For example, the density may be identified by the color of the area, such as making areas with "high" density red, areas with "medium" density yellow, and areas with "low" density blue.
