python alphashape

alphashape_opt = alphashape.optimizealpha(bottom_points)
alphashape_obj = alphashape.alphashape(bottom_points, alphashape_opt)
hull_result = hull.exterior.coords.xy

 

遍历结果：

for k in range(len(hull_result[0])):
　　x1 = int(hull_result[0][k])
　　y1 = int(hull_result[1][k])

 

 

原始数据：

[(412, 319), (179, 127), (274, 206), (129, 277), (265, 397), (35, 188)]

 

输出数据：

(array('d', [122.0, 237.0, 363.0, 260.0, 158.0, 41.0, 122.0]), array('d', [245.0, 206.0, 173.0, 100.0, 122.0, 154.0, 245.0]))
