Abstract： The real-time measurement of rail is more important with the rapid development of high-speed railway. A fast 3D imaging based on the Time-of-Flight camera is proposed to meet the speed and 3D imaging requirements of rail detection. Refer to calculate the round-trip time of light in the air, Time-of-Flight camera obtains the intensity and depth information of object. The rough rail data is extracted from the rail point-clouds by changing the imaging depth of the camera, and the precise data is obtained by combining the 2D images with the depth data. Then the 3D data of rail is quickly obtained. An experimental platform was set up to take the rail images with different imaging depths, and the physical dimensions and volume of rail were figured out.
Key words : rail,；3D imaging；Time-of-Flight camera
