The excel table provides simple solution to this by switching X and Y coordinates and accounting -12.859 degrees of sheer of the original image. The polar coordinates and the Cartesian coordinates can be related using the following equations: x rcos and y rsin. I am trying to convert Image from form Cartesian to polar and back to Cartesian but there is loss in the image, please help me to optimize my code-with scipy-import numpy as np import cv2 from import geometrictransform def topolar(img, order5): maxradius 0.( img. Use import.csv that comes with the app to create your own import file, save with radius, polar, alpha columns.ĭo not use the raw_polar column, as it is there only for specific calculation with image being only visible from a specific view. rgrid np.meshgrid(thetai, ri) Convert the r and theta grids to Cartesian coordinates X, Y polar2cart(rgrid.

Calculates translation of coordinate systems.

Feeds on data from user selected csv file The conversion of complex numbers to polar co-ordinates are explained below with examples.

I created it out of pure interest to see how python is working and I needed an app that converts Polar coordinates of stars based on an image of the galaxy that I created earlier ) Sharing.
