read wiki: hough transform detect lines on image.

every point in hough space 1 line on image. stronger peak on hough image - longer line on original image.

also hough image can tell widths of lines: wide line set of parallel lines close each other, on hough space r-coordinate of peak corresponding wide line broaden proportionally width, angular coordinate broaden, not noticeably.
