> 注意坐标系，阿里云这个应该是高德坐标系，在百度地图上显示需要转换下。
```js
//将腾讯/高德地图经纬度转换为百度地图经纬度
qqMapTransBMap(lng, lat) {
let x_pi = 3.14159265358979324 * 3000.0 / 180.0;
let x = lng;
let y = lat;
let z = Math.sqrt(x * x + y * y) + 0.00002 * Math.sin(y * x_pi);
let theta = Math.atan2(y, x) + 0.000003 * Math.cos(x * x_pi);
let lngs = z * Math.cos(theta) + 0.0065;
let lats = z * Math.sin(theta) + 0.006;
return {
lng: lngs,
lat: lats
}
}
```
转换过了 没有效果， 地图的点往上偏移了点
