Calculate distance between points in polygon

I found a lot of posts on how to calculate distance between two points or from one point to polygon but I simply can’t find how to calculate distance of each edge. I have a polygon, where the coordinates are these:

 [[[623 284]] 

 [[526 256]]

 [[532 189]]

 [[504 166]]

 [[323 175]]

 [[276 219]]

 [[119 221]]

 [[  1 272]]

 [[  0 473]]

 [[615 479]]]

I simply want to calculate length of each edge. Maybe I should use (math.dist(p, q)) with for loop or something?

Answer

If points coordinates are stored in two python lists x and y, then you can calculate each edge length with:

import numpy as np

x.append(x[0])
y.append(y[0])

d = [np.sqrt((x[i + 1] - x[i])**2 + (y[i + 1] - y[i])**2) for i in range(len(x) - 1)]

The append is required in order to close the polygon and calculate all edges length. With points you provided above, the edges distances are:

[100.96038827183659, 67.26812023536856, 36.235341863986875, 181.22361876973983, 64.38167441127949, 157.01273833673497, 128.5496013218244, 201.0024875467963, 615.0292675962665, 195.1640335717624]
