| titleOfInvention | Water surface area measuring method based on unmanned aerial vehicle vision |
| abstract | The invention discloses a water surface area measuring method based on unmanned aerial vehicle vision, which is characterized in that an unmanned aerial vehicle with photographing and height measuring equipment is adopted, and the measured water surface is provided with a reference object with image size parameters stored in the unmanned aerial vehicle; before the unmanned aerial vehicle takes off, firstly, the height of the measured water surface is measured and stored; after the unmanned aerial vehicle takes off, acquiring a water surface picture while keeping the set altitude, and converting the RGB color space of the acquired picture into YCrCb space for highlight detection; highlight enhancement is carried out on the detected picture, and a highlight area is marked; canny edge detection; translating and synthesizing the edges of the pictures; and comparing the reference object, and calculating the water surface area according to a scale. Thereby based on unmanned aerial vehicle visual technology, make the convenient easy realization of surface of water area measurement, and to not equidimension, have the water area of highlight interference to propose corresponding solution, have the advantage that robustness is strong and application scope is wide. |
