Provided is a one-key digital aerial image data processing method. The aerial image data processing method specifically comprises: acquiring all aerial photography images captured by an unmanned aerial vehicle in an aerial photography area, and sequentially carrying out filter processing on each aerial photography image; constructing a high-precision calibration field, according to the high-precision calibration field, determining a distortion correction parameter of a camera to be calibrated loaded on the unmanned aerial vehicle, and carrying out lens distortion correction on each filtered aerial photography image; and carrying out aerial triangulation, acquiring an exterior orientation element of each aerial photography image according to an aerial triangulation result, according to the exterior orientation element of the image, determining an orthographic image corresponding to each aerial photography image, and stitching an orthographic image of the aerial photography area by means of an image stitching algorithm according to the orthographic mage corresponding to each aerial photography image. The aerial photography image of the unmanned aerial vehicle is processed by means of the filtering, the lens distortion correction, the aerial triangulation, and the image stitching, so that the aerial photography image can meet aerial photography measurement requirements.

Abrégé

A utility vehicle for power emergency repair includes a cab, a carriage and a lighting device, including mounting bases, a wire pole, a rotary base and a lamp assembly. A rotary shaft is bridged between the mounting bases, and the rotary base is fixedly connected to the rotary shaft. First and second positioning units are provided on the top of the carriage. The rotary base has first and second positioning surfaces, the first positioning unit includes a first limiting platform, and the second positioning unit includes a rotation limiting plate and positioning plates. The positioning plates is supported on a lower end surface of the rotation limiting plate. The utility vehicle further includes a driving assembly and first and second contacts. A trigger signal is generated and the driving assembly is controlled to release braking on the rotary shaft when the first and second contacts contact each other.
