Three-dimensional scanning type laser radar visibility meter

The invention discloses a three-dimensional scanning type laser radar visibility meter, which belongs to the technical field of visibility detection, and comprises a visibility sensor, a three-dimensional scanning device and an electric cabinet, the visibility sensor is arranged on the three-dimensional scanning device and is driven to carry out horizontal and oblique layered scanning; the visibility sensor is used for obtaining an extinction coefficient of atmosphere in a scanning range; the electric control box is used for controlling the three-dimensional scanning device and the visibilitysensor and calculating the backward scattering coefficient of the atmosphere by utilizing the extinction coefficient. The meter is simple in structure and high in measurement precision, has high reliability and environmental adaptability, can freely change the detection angle, effectively monitors and recognizes visibility changes in different directions, and makes accurate and timely judgment andfeedback for weather phen
