The invention discloses a reservoir capacity measuring and calculating method based on an airborne laser radar, and the method comprises the steps: obtaining a to-be-measured reservoir region, generating a plurality of kml files according to the to-be-measured reservoir region, selecting an unmanned plane airborne laser radar, carrying out the field laser point cloud data collection of the to-be-measured reservoir region, obtaining the Li DAR point cloud data collected by an unmanned plane, and calculating the storage capacity of a reservoir. And filling or repairing the missing part of the filtered point cloud data based on an inverse distance weighted interpolation method, generating a plurality of digital elevation models, calculating the gradient of the reservoir, sequentially setting different reference water level planes and the gradient of the reservoir, and calculating the storage capacity of the reservoir. The unmanned aerial vehicle airborne laser radar technology has the characteristics of high operability, high result precision, high efficiency, few control points, short working period, no limitation of working time and working range and the like. And the geographic information technology is utilized to carry out post-processing on the collected point cloud, the current reservoir capacity of the reservoir is rapidly updated, a reservoir capacity curve is fitted, and rapid estimation of the reservoir capacity under each characteristic water level is realized.
