Forest area canopy density information acquisition device and measurement method

A forest area canopy density information acquisition device disclosed by the present invention comprises a mobile base, a measuring rod, a tool box, a telescopic rod, a supporting table and a measuring rod, one end of the measuring rod is movably connected with a transmission disc through a connecting piece, the measuring rod comprises a rod body, the upper surface of the rod body is provided with multiple light sensors, the multiple light sensors are arranged in the direction of the rod body in a single row at equal intervals, the bottom face of the rod body is fixedly connected with a data processing unit, and the data processing unit records the time when each light sensor receives light and calculates the canopy density of the forest area. The problems that according to an existing measuring method, due to the fact that low vegetation and high vegetation intersect with each other, the shooting situation is difficult to judge accurately, the distance between the high-altitude operation height of an unmanne
