摘? ?要：為了快速測定樹障環境下的任意多邊形的面積，提出了基于多旋翼無人機GPS坐標計算的樹障面積快速測定法。該方法通過無人機定位取點并選取待測區域外任意一點與多邊形各頂點相連接形成多個三角形來計算任意多邊形的面積，并在此基礎上開發出了一款面積測量軟件——無人機面積測量軟件1.0。實地面積測量結果表明，該方法能夠快速的對指定區域進行面積測量且相對誤差精度可達到95%以上。

Abstract：In order to quickly measure the area of any polygon in the tree barrier environment，this paper proposes a rapid measurement method of tree barrier area based on GPS coordinates of multi-rotor UAV. The method calculates the area of an arbitrary polygon by taking the points and selecting a discretionary point outside the area to be measured to connect with the vertices of the polygon to form triangles. Based on this，an area measurement software -- UAV area measurement software 1.0 is developed. Field area measurement results show that the method can quickly measure the area of the specified area and the relative error precision can reach95% or above.
