Abstract: The present application provides a 3D laser radar and a legged robot. The 3D laser radar includes a vertical scanning unit and a horizontal rotating device. The vertical scanning unit includes a mounting base (1), and a laser receiver (2), a convex lens (3), a laser transmitter (4) and a reflector (5) sequentially provided on the mounting base. The laser receiver (2) is provided at a focus position of the convex lens (3). The laser transmitter (4) is provided on a main optical axis of the convex lens (3). The reflector (5) is rotatably provided on the mounting base (1). A rotation center of the reflector (5) coincides with the main optical axis of the convex lens (3). A laser pulse signal is used to achieve environment scanning in a vertical plane through the rotation of the reflector (5), and achieve 3D environment scanning through the horizontal rotating device.
