Methods and systems are provided for detecting and measuring physical conditions of railway tracks based on distance measurements of images. In an embodiment, at least one object related to a railway track condition is detected in at least one image. A first point and a second point on at least one object are detected. A pixel distance between the first point and the second point is measured, and a railway track condition measurement based on the physical distance is determined using a transformation model based on the pixel distance between the first point and the second point. An alarm is issued when the measured value of the railway track condition based on the physical distance exceeds a predetermined threshold value.

    本发明提供了基于图像的距离测量来检测和测量铁路轨道的物理状况的方法和系统。在实施例中,在至少一幅图像中检测与铁路轨道状况相关的至少一个物体。检测至少一个物体上的第一点和第二点。测量第一点和第二点之间的像素距离,并根据第一点和第二点之间的像素距离,使用转换模型确定基于物理距离的铁路轨道状况测量值。当基于物理距离的铁路轨道状况测量值超过预定阈值时,就会发出警报。
