1, how to extract the edge of the image or up and down or so two, and then to fit it to calculate the approximate equation of the straight line?
2, how to control or up and down on the edge of the coordinates of point a average calculated?
Watch a lot of data, found that less information about the opencv pixel coordinates, to consult,

I think the main reference, hoff straight line detection this thing, look at the document opencv official

Is, from the perspective of the Hough transform line before, but due to the parameter problem, it is the result of the line,,, so I want from pixels lixia hand again, don't know if you have any good Suggestions?
