How to reconnect between line that has a curvature or blank in the middle of it.

image description

I'm using HoughLinesP to get the line. I'm trying to reconnect line inside green circle because the line still has another line on the other side. can anyone help me or just give me a direction to solve it.

Thank you very much.

you can also try to increase the maxLineGap value in HoughLinesP or close it with morphological operations

(Suggestion) - loop over all lines one by one and compare slop with other lines . (If they have same slop and their perpendicular distance ≈ 0 ) use LineIterator -> get their points --> Use fitLine to fit those points to 1 single line .
