IOS development based on Baidu map (7) -- convert Baidu coordinates to Google coordinates

Subject.

Assume that Baidu coordinates are (x, y). In iOS-based Baidu map development (6), we regard (x, y) as Google coordinates and convert them, after conversion, the coordinates (x1, Y1) are obtained ). Then the calculation method of the real Google coordinates (X2, Y2) is:

X2 = 2 * X-x1;

Y2 = 2 * Y-Y1;

Note:

1. The conversion result is very similar to the real Google coordinates, but there is still an error.

2. Is this conversion within the scope permitted by the policy? Be cautious.
