camproject 0.33

a camera projection lib to calculate the ray direction of a pixel and vice versa

# camera
a python module for camera projection and reprojection

Maintainer
----------
* Martin Israel <[e-mail]>

Requirements
------------

* python 2.6, 2.7, or 3.x
* NumPy


Installation
------------
The easiest way is to install it from Pypi with:
`$ pip install camproject`

To install system-wide from source distribution:
`$ python setup.py install`

Quickstart-Usage
----------------

import numpy as np
import camproject

P = np.array([[1],[0],[10],[1]]) # this is a point in 3D (e.g. in meters)
cam = camproject.Camera()
cam.intrinsics(640,512,1000,320,260) # inner parameters: (in pixels)
# (im_width,im_height, focal_length, centerpixel_x, centerpixel_y)
cam.attitudeMat(np.eye(4)) # outer parameters: point to z-direction
p = cam.project(P) # gives pixel coordinates on the image

to reproject it back to the 3D world we use this code

Q = cam.reprojectToPlane(p,distance=10)
