distance between two points opencv python code example

Example 1: python distance of coordinates

dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)

Example 2: distance formula in python

import math.
def calculateDistance(x1,y1,x2,y2):
dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
return dist.
print calculateDistance(x1, y1, x2, y2)
