1. A computer-implemented method of vehicle collision or crash reconstruction using drone data, comprising: receiving, by one or more processors, drone data via wireless communications, the drone data being generated by one or more drones and including vehicle collision or crash images of (i) vehicles involved in a vehicular collision or crash, and (ii) a scene of the vehicle collision or crash, performing, by one or more processors, a photogrammetric analysis of the vehicle collision or crash images, the photogrammetric analysis including calculating respective speeds and respective directions of the vehicles before, during, and after the vehicle collision or crash; generating, by one or more processors, a virtual accident reconstruction model of the vehicle collision or crash based upon the photogrammetric analysis of the vehicle collision or crash images, the virtual accident reconstruction model generated by overlaying respective movements of the vehicles, as indicated by the respective speeds and respective directions of the vehicles before, during, and after the vehicle collision or crash, onto respective locations of a model of a road on which the vehicle crash or collision occurred; and assigning, by one or more processors, a percentage of fault to each driver and vehicle involved in the vehicle collision or crash based upon an analysis of the virtual accident reconstruction model of the vehicle collision or crash.
