Title:
DATA PROCESSING METHOD REGARDING IMAGE, AND UNMANNED AERIAL VEHICLE, SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/061772
Kind Code:
A1
Abstract:
Disclosed are a data processing method regarding an image, and an unmanned aerial vehicle, a system and a storage medium. The method comprises: determining a first elevation window set on an initial digital surface model, wherein the first elevation window set comprises first elevation windows, each first elevation window comprises an elevation vacancy point, and an elevation value of a first elevation vacancy point is an estimated elevation value; determining a second elevation window set in an area, apart from the elevation vacancy point, in the initial digital surface model, wherein the second elevation window set comprises second elevation windows; performing, on the basis of a preset minimized cost algorithm, optimization calculation on each elevation value covered by each second elevation window and each elevation value covered by the matching first elevation window to obtain an elevation supplement value of each elevation vacancy point; and updating the estimated elevation value in the elevation vacancy point according to the elevation supplement value to obtain an updated digital surface model. The present embodiments can fill an elevation vacancy area, thereby better obtaining a digital surface model.
