The invention discloses a method for performing blind source error compensation on an airborne laser radar based on data driving. The method comprises the following steps of preparing and installing the airborne laser radar and an external inertial measurement unit; obtaining two sets of airborne laser radar data according to an airborne laser radar data generation theoretical model; calculating correction values of a rolling angle and a pitch angle and performing primary coordinate correction; respectively extracting point features in the two sets of airborne laser radar data; matching the point features to obtain point feature matching pairs; establishing a Bursa model through the feature matching pairs and performing secondary coordinate correction; averaging the two sets of corrected airborne laser radar data to obtain the airborne laser radar data subjected to blind source error compensation. By performing feature analysis and processing on the two sets of airborne laser radar data, influence of blind source errors on positioning accuracy of the airborne laser radar data can be reduced by means of a data driving mode, and airborne laser radar data accuracy is improved.
