Summary: | The embodiment of the invention provides a laser scanning device and a rail foreign matter detection method, the laser scanning device comprises a three-dimensional laser radar and a plurality of reflectors, the three-dimensional laser radar can emit a plurality of scanning light rays, the included angles between two adjacent scanning light rays are the same, the number of the reflectors is multiple, and the three-dimensional laser radar can emit the scanning light rays. The plurality of reflectors and the plurality of scanning light rays are arranged in one-to-one correspondence, the reflectors are located on the paths of the corresponding scanning light rays to enable the corresponding scanning light rays to deflect partially and form deflected light rays, the included angle between the deflected light rays and the scanning light rays is alpha, and the included angles alpha corresponding to the paths of the plurality of scanning light rays after deflection are the same; and the included angle alpha is small |
