调研了python和java多种实现方式的转换发现有的不符合需求原因还没找到。
我是用百度地图返回的poi边界返回的是墨卡托坐标
转换的原理没有深入研究直接拿来用的测试可行非常感谢https://blog.csdn.net/qq_33734315/article/details/121071650
挺好奇MCBAND,MC2LL 这两个变量是从哪里找到的还是自己研究出来的太厉害了。 下面两种实现转换后的经纬度均为百度坐标系 调研的java代码实现

三、调研资料
http://www.site-digger.com/tools/mct2latlng.html
这个工具里面测试了一下返回的经纬度坐标是百度的坐标系
https://www.cnblogs.com/feffery/p/11023673.html
这个实现用上面的测试用例测试没有通过不知道是不是墨卡托用到的标准不同导致的
