A laser scanning ranging module provided by the present application comprises a multi-faceted prism, a receiving lens, a photoelectric detector and an emission channel, the multi-faceted prism is rotatable, the multi-faceted prism is provided with a plurality of inclined prism reflecting surfaces along the circumferential direction of a rotating shaft, the emission channel emits pulse laser, and the pulse laser is reflected to the surface of a target object through the multi-faceted prism. Light signals formed by scattering of pulse laser on the surface of an object are reflected by the multi-face prism and then converged to the photoelectric detector through the receiving lens, and included angles between prism reflecting faces of the multi-face prism and a rotating shaft of the multi-face prism are different. The problem of low scanning efficiency caused by view field waste when a 360-degree full-view-field laser radar limits a scanning view field range is solved. 本申请提供一种激光扫描测距模块，包括多面棱镜、接收透镜、光电探测器和发射通道，多面棱镜
