Hi,
I am using HoughLinesP to calculate lines from image. But the line segments from same line have different angles.
the segments start and end points and angle (in degrees) and length.
id = 0 start(x,y) = (1331 , 790 ) end(x,y) = (1366 , 794 ) Angle = 6.52311 len = 35.2278
id = 2 start(x,y) = (1508 , 807 ) end(x,y) = (1543 , 810 ) Angle = 4.90158 len = 35.1283
id = 4 start(x,y) = (1291 , 786 ) end(x,y) = (1328 , 789 ) Angle = 4.63781 len = 37.1214
id = 8 start(x,y) = (1391 , 795 ) end(x,y) = (1423 , 798 ) Angle = 5.35854 len = 32.1403
id = 9 start(x,y) = (1224 , 779 ) end(x,y) = (1261 , 782 ) Angle = 4.63781 len = 37.1214
To calculate angle i used atan2(y2-y1,x2-x1)*180/3.14
I am expecting same angle since the segments are part of same line.
Is there a way to improve the angle calculation or improving line detection ?
thanks.
