High-precision integrated track geometrical parameter measurement method
The invention provides a high-precision integrated track geometrical parameter measurement method, an integrated track comprises a plurality of target tracks, and the method comprises the following steps: irradiating the target tracks through a light source; acquiring an image on the target track through an image acquisition device; extracting light bar image information from the acquired image through an image recognition algorithm; simultaneously moving the light source and the image receiving equipment for a set distance, and then continuously extracting the light strip image information until the light source and the image receiving equipment move to traverse the target track; fitting the extracted light bar image information of the target track along the track direction to obtain geometric parameters of the target track; and geometrically unifying the appearance of each target track to obtain the overall geometric parameters of the integrated track. A high-precision recognition algorithm is adopted to extract light bars in the image, so that the efficiency and accuracy of track geometric parameter measurement are improved; evaluation of the overall geometrical parameter condition of the integrated track is realized through a non-contact measurement means.
本申请提供一种高精度集成轨道几何参数测量方法，集成轨道包括多条目标轨道，包括以下步骤：通过光源照射目标轨道；通过图像采集设备对目标轨道上的图像进行采集；对采集的图像通过图像识别算法提取光条图像信息；将光源和图像接收设备同时移动设定距离后继续提取光条图像信息，直至光源和图像接收设备移动遍历目标轨道；将提取的目标轨道的各个光条图像信息沿该轨道方向进行拟合，得到目标轨道的几何参数；将各条目标轨道的外形几何统一基准，得到集成轨道的整体几何参数。采用高精度识别算法对图像中的光条进行提取，提高了轨道几何参数测量的效率和准确度；通过非接触式测量手段实现了对集成轨道总体几何参数情况的评价。
