用python绘制两条MULTILINESTRING的最小矩形

要绘制两条MULTILINESTRING的最小矩形，可以使用Python的Shapely库来实现。具体步骤如下：

1. 导入需要的库：

from shapely.geometry import MultiLineString, Polygon

2. 定义两条MULTILINESTRING：

line1 = MultiLineString([(0, 0), (1, 1), (2, 0)])
line2 = MultiLineString([(0, 1), (1, 0), (2, 1)])

3. 合并两条MULTILINESTRING：

merged_line = line1.union(line2)

4. 计算最小矩形：

min_rect = merged_line.minimum_rotated_rectangle

5. 将最小矩形转换为Polygon对象：

rect_poly = Polygon(min_rect.exterior.coords)

6. 最后可以使用Matplotlib库将Polygon对象绘制出来：

import matplotlib.pyplot as plt

plt.plot(*rect_poly.exterior.xy)
plt.show()

完整代码如下：

from shapely.geometry import MultiLineString, Polygon
import matplotlib.pyplot as plt

line1 = MultiLineString([(0, 0), (1, 1), (2, 0)])
line2 = MultiLineString([(0, 1), (1, 0), (2, 1)])
merged_line = line1.union(line2)
min_rect = merged_line.minimum_rotated_rectangle
rect_poly = Polygon(min_rect.exterior.coords)

plt.plot(*rect_poly.exterior.xy)
plt.show()
