METHOD AND DEVICE FOR MEASURING MANAGEMENT DIMENSION OF TRACK RAIL

PROBLEM TO BE SOLVED: To provide a method and device for measuring a management dimension of track rails that sufficiently save the labor of measuring work by acquiring the information about a measuring position and the management dimension as a set. SOLUTION: This device 10 for measuring the management dimension of the track rail comprises a first reflective target 21 for optically distinguishably showing the information about the measuring position, second and third reflective targets 22 and 23 for optically distinguishably showing measuring object parts of right and left rails 51 and 52, a digital camera 30 for photographing a plurality of images including the first to third reflective targets by flash photographing the first to third reflective targets while the angle is changed, and a controller 40 for analysis-processing data of the photographed images. The controller identifies the information about the measuring position, calculates the management dimension such as creeping amount d by principle of photogrammetry, and acquires the information about the measuring position and the management dimension as the set.
