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 smaller than the included angle between two adjacent scanning light rays. According to the embodiment of the invention, the laser scanning device is provided with a plurality of reflectors which are in one-to-one correspondence with a plurality of scanning light rays, and parts of the scanning light rays are deflected through the reflectors to form deflected light rays, so that the resolution of a three-dimensional laser radar is improved.
本发明实施例提供一种激光扫描装置和轨道异物检测方法,所述激光扫描装置包括三维激光雷达和反射镜,三维激光雷达可发射多条扫描光线,且相邻两条扫描光线之间的夹角相同,反射镜为多个,多个反射镜与多条扫描光线一一对应设置,反射镜位于对应的扫描光线的路径上以使对应的扫描光线的部分发生偏转并形成偏转光线,偏转光线与扫描光线的夹角为α,多个扫描光线偏转后的路径对应的夹角α相同,且夹角α小于相邻两条扫描光线之间的夹角。本发明实施例的激光扫描装置设置多个反射镜与多条扫描光线一一对应设置,通过反射镜将扫描光线的部分进行偏转以形成偏转光线,从而提升三维激光雷达的分辨率。
