[0055] Reference Figure 1 The embodiment of the present invention provides a vehicle component wiring harness assembly detection method, which specifically includes the following steps:

[0056] S101, performing perspective scanning of a target vehicle component at multiple perspective angles to obtain a first perspective image corresponding to each perspective angle;

[0057] S102, performing line bundle identification point detection on the first perspective image to obtain position information of each line bundle identification point in the first perspective image;

[0058] S103, performing three-dimensional reconstruction on the target wiring harness in the target vehicle component according to the position information to obtain three-dimensional spatial position information of the target wiring harness;

[0059] S104, obtaining assembly drawing information of the target vehicle component, and judging whether the target wiring harness is assembled properly according to the three-dimensional space position information and the assembly drawing information.

[0060] The embodiment of the present invention performs perspective scanning on the target vehicle component to obtain a perspective image, and performs wire harness identification point detection based on the perspective image, so that the target wire harness can be three-dimensionally reconstructed to obtain the three-dimensional spatial position information of the target wire harness, which is then compared with the assembly drawing information of the target vehicle component to determine whether the target wire harness is properly assembled. There is no need to manually disassemble and identify the target vehicle component, and the actual layout of the target wire harness in the whole vehicle state can be accurately presented, thereby improving the efficiency and accuracy of wire harness assembly detection.

[0061] As an optional implementation, a perspective scan is performed on the target vehicle component at multiple perspective angles to obtain a first perspective image corresponding to each perspective angle, which specifically includes:

[0062] S1011, determining multiple perspective surfaces of the target vehicle component, and determining corresponding perspective angles according to the perspective surfaces;

[0063] S1012, performing multiple perspective scans on the target vehicle component according to the perspective surface by using a perspective device to obtain a first perspective image.

[0064] Specifically, for the target vehicle component to be detected, at least two perspective surfaces, such as the bottom surface and the side surface, can be determined in advance, and the perspective angle corresponding to each perspective surface can be determined according to the vertical angle of the plane where the perspective surface is located; the target vehicle component is perspectively scanned from each perspective surface by a perspective device to obtain a first perspective image at each perspective angle.

[0065] It can be understood that the X-ray device uses X-rays to perform X-ray scanning, and objects that can be penetrated include plastics, ceramics, glass, thin metals, etc. In an embodiment of the present invention, the X-ray device can be used to perform X-ray scanning on non-thick metal parts in the car (such as the armrest box).

[0066] As an optional implementation, performing line beam identification point detection on the first perspective image to obtain position information of each line beam identification point in the first perspective image specifically includes:

[0067] S1021, obtaining identification information of each preset wiring harness identification point;

[0068] S1022, performing target detection on the first perspective image according to the identification information to obtain position information of each wiring harness identification point;

[0069] Among them, each harness identification point of the target harness is provided with corresponding identification information.

[0070] Specifically, the embodiment of the present invention pre-arranges a plurality of wiring harness identification points (which can be arranged at equal intervals) on the vehicle wiring harness, and corresponding identification information is arranged at each wiring harness identification point. The identification information can be a digital or letter code, or other text or pattern information that can represent the corresponding wiring harness identification point. The embodiment of the present invention is not limited to this.

[0071] It can be understood that the objects that the perspective device can penetrate include plastics, ceramics, glass, thin metal, etc. In an embodiment of the present invention, physical wiring harness identification points can be formed on the wrapping layer of the vehicle wiring harness through thick metal or other difficult-to-penetrate materials, and the identification information can be recorded through numbers, letter codes, text or pattern information, so that the position information of each wiring harness identification point can be obtained through target detection in the perspective image.

[0072] As an optional implementation, a target wiring harness in a target vehicle component is three-dimensionally reconstructed according to the position information to obtain the three-dimensional spatial position information of the target wiring harness, which specifically includes:

[0073] S1031, determining first coordinate information of the harness identification point at a corresponding perspective angle according to the position information;

[0074] S1032, determining spatial coordinate information of the harness identification point according to the first coordinate information at multiple perspective angles;

[0075] S1033, performing three-dimensional reconstruction of the target wire harness according to the spatial coordinate information of each wire harness identification point to obtain a first three-dimensional spatial model of the target wire harness;

[0076] S1034. Determine the three-dimensional spatial position information of the target wire harness according to the first three-dimensional spatial model.

[0077] Specifically, the position information of the wiring harness identification points in the perspective image is converted into coordinate information under the corresponding perspective angle (perspective plane), and the spatial coordinate information of each wiring harness identification point can be determined using the binocular vision principle based on the coordinate information under multiple perspective angles (perspective planes); after determining the spatial coordinate information of all wiring harness identification points on the target wiring harness, the true state of the target wiring harness in the three-dimensional space can be restored through a three-dimensional reconstruction algorithm to obtain a first three-dimensional spatial model of the target wiring harness, thereby determining the three-dimensional spatial position information of the target wiring harness (the three-dimensional spatial coordinates of each point of the target wiring harness).

[0078] As an optional implementation, judging whether the target wiring harness is properly assembled according to the three-dimensional spatial position information and the assembly drawing information specifically includes:

[0079] S1041, determining the expected wiring harness direction of the target wiring harness according to the assembly drawing information;

[0080] S1042, determining the actual wiring harness direction of the target wiring harness according to the three-dimensional spatial position information;

[0081] S1043, comparing the expected wiring harness direction with the actual wiring harness direction, and judging whether the target wiring harness is qualified for assembly according to the comparison result.

[0082] Specifically, the expected wiring harness direction can be determined based on the target wiring harness direction drawn in the assembly drawing information and represented by a vector. The actual wiring harness direction can be determined by combining the three-dimensional spatial position information and can also be represented by a vector. The two are compared and when the angle deviation is within the preset threshold, the target wiring harness can be judged to be assembled properly.

[0083] As an optional implementation, judging whether the target wiring harness is properly assembled according to the three-dimensional spatial position information and the assembly drawing information specifically includes:

[0084] S1044, determining the three-dimensional space size information of the non-wiring harness part of the target vehicle component according to the assembly drawing information;

[0085] S1045, determining the spatial distance between the target wire harness and the non-wire harness portion according to the three-dimensional spatial position information and the three-dimensional spatial size information;

[0086] S1046. Determine whether the target wiring harness is properly assembled based on the spatial distance and a preset distance threshold.

[0087] Specifically, based on the stereoscopic view of the non-wiring harness part drawn in the assembly drawing information and the size information of the non-wiring harness part described, the three-dimensional spatial size information of the non-wiring harness part can be restored. Combined with the three-dimensional spatial position information, the spatial distance between the target wiring harness and the non-wiring harness part can be determined. The spatial distance is compared with a preset distance threshold. When the spatial distance is not less than the distance threshold, it can be determined that the target wiring harness is assembled properly.

[0088] As an optional embodiment, the vehicle component wiring harness assembly detection method further includes the following steps:

[0089] S105, constructing a second three-dimensional spatial model of the non-wiring harness portion of the target vehicle component according to the assembly drawing information;

[0090] S106, determining an internal three-dimensional space model of the target vehicle component according to the first three-dimensional space model and the second three-dimensional space model;

[0091] S107. Visually display the internal three-dimensional space model.

[0092] Specifically, the dimensional parameters of the non-wiring harness part of the target vehicle component can be determined based on the assembly drawing information, and a second three-dimensional space model of the non-wiring harness part can be constructed based on the dimensional parameters. Combined with the first three-dimensional space model of the target wiring harness obtained in the previous steps, a complete three-dimensional space model of the interior of the target vehicle component can be obtained, and visualized on the screen, so that the tester can intuitively understand the internal wiring harness layout of the target vehicle component.

[0093] The above is a description of the method steps of the embodiment of the present invention. It can be recognized that the embodiment of the present invention performs perspective scanning on the target vehicle component to obtain a perspective image, and performs harness identification point detection based on the perspective image, so that the target harness can be three-dimensionally reconstructed to obtain the three-dimensional spatial position information of the target harness, and then compared with the assembly drawing information of the target vehicle component to determine whether the target harness is assembled properly, without the need to manually disassemble and identify the target vehicle component, and can accurately present the real layout of the target harness in the whole vehicle state, thereby improving the efficiency and accuracy of harness assembly detection.
