在列表中仅找到唯一坐标 [英] Finding ONLY Unique Coordinates in List

问题描述

我有一个类似的坐标列表

I have a list of coordinates like

list_cor = 
    [[4190091.4195999987, 7410226.618699998], 
    [4190033.2124999985, 7410220.0823], 
    [4190033.2124999985, 7410220.0823], 
    [4190035.7005000003, 7410208.670500003], 
    [4190033.2124999985, 7410220.0823], 
    [4190022.768599998, 7410217.844300002]]

我只需要获取这些值:

[[4190091.4195999987, 7410226.618699998], 
[4190035.7005000003, 7410208.670500003], 
[4190022.768599998, 7410217.844300002]]

尝试了numpy.unique()，但它添加了我不需要的项目[4190033.2124999985, 7410220.0823].

Tried numpy.unique() but it adds this item [4190033.2124999985, 7410220.0823], which I don't need.

推荐答案

使用numpy.unique和axis和return_counts参数:

arr, uniq_cnt = np.unique(list_cor, axis=0, return_counts=True)
uniq_arr = arr[uniq_cnt==1]
