Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0043] In one embodiment, such as figure 1 As shown, a bogie clearance detection method is provided, comprising the following steps:
[0044] S200. Acquire first point cloud data of a standard bogie, and use the first point cloud data and a preset first gap width to model to obtain a standard model.
[0045] Wherein, the above-mentioned first point cloud data may be obtained by projecting a Gray code grating onto a standard bogie from a 3D camera, and of course may also be point cloud data obtained by other laser scanning methods. The first gap width is the minimum value...

The invention relates to a bogie gap detection method and device, computer equipment and a storage medium. According to the method, the first point cloud data of the standard bogie is acquired, the standard model is obtained by modeling the first point cloud data and the preset first gap width, then the second point cloud data of each part of the to-be-detected bogie is acquired, the second point cloud data is matched with the standard model, and the to-be-detected bogie is detected according to the matching result. And finally, according to the second gap width and the first gap width, whether the bogie gap is qualified or not is judged, and efficient automatic detection of the bogie gap is achieved.
Description
technical field [0001] The present application relates to the technical field of part gap detection, and in particular to a bogie gap detection method, device, computer equipment and storage medium. Background technique [0002] The bogie is one of the most important parts of a railway vehicle, used to bear the weight and load of the vehicle body and guide the vehicle to run along the railway track, to ensure that the vehicle runs smoothly on straight lines and curves, and to reduce the vibration caused by the vehicle when it is running and impact, so the design of the bogie also directly determines the stability of the vehicle and the comfort of the vehicle. [0003] In the maintenance process of railway vehicles, it is necessary to detect the gap between the bogie key and the wheel axle to avoid excessive gaps caused by changes such as wear and tear of some parts. At present, the contact measuring tool feeler gauge is generally used to measure the clearance between the ke...
