IOS Baidu map track record road fitting

IOS Baidu map track record road fitting

Recently, I am working on a small demo to try track records.

The recording track must be constantly retrieved and recorded to the database.

During the discount, the link will be directly connected at the corner of the road and will not fit with the road. Here I will talk about my solution.

I called the path planning api of Baidu map. In this way, the path fitting function can be realized.

Note: This dome is running on a real machine and an error will be reported on the simulator. Pay attention when downloading.

For various reasons, images are taken on mobile phones.

Take a look at the previous figure:

In the above method, we obtain the road section of the line from the returned line, obtain the points in the road section from the road section, and draw the lines for these points.
