The invention discloses a method for generating a road traffic accident scene map, and the method comprises the steps: obtaining a road traffic accident scene map set based on an unmanned plane device; preprocessing the photos in the road traffic accident scene map set to obtain a photo A; extracting distance identification panel information in the photo A; according to the distance identification panel information, determining a current scale a of the photo A; extracting elements in the photo A and photo sizes corresponding to the elements; obtaining the real size of the corresponding element according to the current scale a and the photo size of the corresponding element; and marking the elements and the real sizes of the corresponding elements in the photo A to obtain a current road traffic accident scene map. According to the invention, automatic photographing is carried out through the unmanned aerial vehicle, manual operation is not needed, field measurement is not needed, and the traffic accident handl
