The invention relates to a standing tree diameter at breast height rapid measuring device and method based on an unmanned aerial vehicle. The device comprises a small rotor unmanned aerial vehicle and a standing tree diameter at breast height measuring box. The stumpage diameter at breast height measuring box comprises a box cover and a box body, the top of the box cover is fixedly connected with the undercarriage of the small unmanned rotorcraft; an ultrasonic ranging sensor is mounted at the bottom of the box body; a laser distance measuring sensor and a stepping motor are embedded behind an opening right in front of the box body; a left cutting arm and a right cutting arm are mounted in the box body, and the tail ends are meshed to form scissor arms; a direct current motor, an angle sensor and a controller are integrated in the box body; when the direct current motor rotates, the left cutting arm, the right cutting arm and the angle sensor are driven to rotate through gear meshing and power transmission; the controller can calculate the diameter at breast height of the stumpage to be measured according to the distance and the angle measured by the sensor. The method can rapidly measure the diameter at breast height of a large number of trees in a complex forest environment where personnel are difficult to reach, and has the advantages of high efficiency, manpower saving, good adaptability and the like.
