I am new to python and have a little problem to solve .. i have an
array with x, y, z co-ordinates in it as a tuple. I am trying to find
the distance between each point and sorting the points according to
the min distance.. i have tried a prog but m stuck bcoz of this error
which I am unable to correct
import cv
from math import floor, sqrt, ceil
from numpy import array, dot, subtract, add, linalg as lin
def calcdist(data):
for p in data:
x = p[0]
y = p[1]
z = p[2]
for i in range(len(data)):
dist = sqrt((x[i]-x[i+1])**2 + (y[i]-y[i+1])**2 +(z[i]-z[i+1]**2))
return dist
def ReadPointCloud(filename):
return [tuple(map(float, l.split()[1:4])) for l in open(filename)]
def main (data):
for i in range(len(data)): # Finding Neighbours
for j in range(len(data)):
dist = calcdist(data)
print dist
if __name__ == '__main__':
data = ReadPointCloud(r'C:\Thesis\NEHreflectance_Scanner_1_part.txt')
data = data[0:100]
main(data)
the error m getting is...
Traceback (most recent call last):
