If there are some turning points ahead, How do you find the turning point? #6

Closed GuoxingYan closed 2 years ago

GuoxingYan commented 2 years ago

If there are some turning points ahead, we find the turning point that is closest to vt as (vt1+1)∗ (subfigure (b) of Fig. 7).

How did you achieve this? Is the implementation of this step in the published code?

I understand that the path has been simplified in the process of creating the graph.

We look forward to your reply.

Hi Yan,

We calculate the orientation value of each pixel (i.e., a unit vector). If the turning angle between a pixel $u$ and $v_t$ larger than a threshold, we can know that a curve road is met.

This is implemented in our code. Each edge object has an attribute orientation to record corresponding information.

Thank you very much for your reply. I understand the question.
