I am working on this problem of finding popping crease of the cricket pitch and I have somewhat achieved what I wanted to do that is I can detect vertical line segments using LSD from opencv but what I dont seem to understand is how to join different line segments on the same line to make a complete line.
The code for finding line segments:
import cv2
import math
import numpy as np
#Read gray image
img = cv2.imread("2.jpg",0)
#Create default parametrization LSD
lsd = cv2.createLineSegmentDetector(0)
#Detect lines in the image
lines = lsd.detect(img)[0] #Position 0 of the returned tuple are the detected lines
print(lines[0][0][0])
ver_lines = []
for line in lines:
angletan = math.degrees(math.atan2((round(line[0][3],2) - round(line[0][1],2)), (round(line[0][2],2) - round(line[0][0],2))))
if(angletan > 85 and angletan < 95):
ver_lines.append(line)
#Draw detected lines in the image
drawn_img = lsd.drawSegments(img,np.array(ver_lines))
#Show image
cv2.imshow("LSD",drawn_img )
cv2.waitKey(0)
Input Image:
Detected lines:
what I would like to have:
