Individual geological disaster emergency investigation method based on remote sensing of small unmanned aerial vehicle

The invention relates to a individual geological disaster emergency investigation method based on remote sensing of a small unmanned aerial vehicle. The individual geological disaster emergency investigation method comprises the following technical steps: customization of a small unmanned aerial vehicle remote sensing system; indoor preparation; field operation; fast processing; overall processing. The invention aims to rapidly, efficiently and accurately obtain overall deformation characteristics of the slope by carrying out rapid and effective deployment and measurement of photo control points based on slope characteristics, using the small unmanned aerial vehicle remote sensing system to automatically acquire slope photos, generating high-precision and high-resolution remote sensing results of a slope by introducing the photo control points in a digital photography measurement processing process, and performing slope deformation detection and measurement on earlier-stage and later-stage remote sensing results after passing the precision inspection and high-precision registration.
