大疆OSDK開發-在模擬器中畫個一箭穿心

使用OSDK中的自主航線飛行的例子，在模擬器中畫一個心形軌跡。

首先計算心形坐標，如下是python程序：

from math import * import matplotlib.pyplot as plt xs = [] ys = [] n = 30 increment = 0.00001 # 天安門中心GPS點 longitude,latitude = 116.353349,40.036001 for i in range(n):t = i*(2*pi/n)x = latitude + (increment * (20 * sin(t) * sin(t) * sin(t)+20));y = longitude + (increment * (12 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t)+15.5));xs.append(x)ys.append(y) plt.plot(xs,ys)

提供一個GPS坐標的例子，如下：?
