Embodiment 1
[0068] refer to image 3 As shown, the rapid measuring device for railway track gauge of the present invention includes an aircraft equipped with a measuring device, and the measuring device includes a three-dimensional camera, a data acquisition module, a data storage module, a data processing module and a power supply.
[0069] The main control module is connected with the 3D camera, the data acquisition module, the data storage module and the power supply, the power supply supplies power to the main control module, and the main control module controls the 3D camera, the data acquisition module and the data storage module; the 3D camera is connected with the data acquisition module ; The data acquisition module is connected with the data storage module; the data storage module is connected with the data processing module.
[0070] The main control module controls the 3D camera, so that the 3D camera takes pictures of the railway track. After the image is sampled by the data ...
Embodiment 2
[0074] refer to Figure 1 to Figure 5 As shown, the present invention discloses a rapid measurement method for railway track gauge, and the measurement steps are as follows:
[0075] Stage 1, data preprocessing.
[0076] Based on the information of the rail head 1, rail waist 2, rail bottom 3, gauge 4 and the inner working surface 5 under the rail head tread, a standard BIM model of the rail is created according to the design requirements of the national standard for rail, and discretized into 3D Point cloud, as a template point cloud for matching. At the same time, according to the image set collected by the aircraft, the measured scene point cloud is constructed, and then the measured rail point cloud is segmented from the scene to obtain the measured point cloud.
[0077] Stage 2, template-oriented point cloud matching.
[0078] In this stage, the point cloud of the standard BIM model is used as the template, and the template-oriented point cloud registration algorithm i...
