The invention discloses a monocular camera look-around compensation device and method for a long and narrow environment laser radar, the compensation device comprises an airborne laser radar and a point cloud compensation device, a monocular camera is fixed on a holder, the holder is used to drag the monocular camera to rotate, and the look-around effect is achieved; the problem that the overlap ratio of the view field of the panoramic camera and the scanning field of the laser radar is not high is avoided, and the problem that the view field angle of a fixed monocular camera is not enough can also be solved. The compensation method is divided into a monocular camera look-around point cloud compensation method and a long and narrow environment compensation method. According to the invention, under the condition of one-time camera-laser radar calibration, single-axis full-angle laser radar compensation can be realized, and the scene scanning density of a low-line-number radar can be compensated with relatively
