pyfly1

A Python wrapper for Point Grey Research's FlyCapture v1 API

Status

This wrapper is currently under development.

work done

• usable support for Point Grey Chameleon USB 2.0 cameras (colour and monochrome)
• Context setup
• Camera start
• grab FlyCapture image as PIL image
• grab FlyCapture image Numpy array

missing features

• support for Firewire, USB 3.0, and Gig-E cameras

Requirements

• python
• cython
• Point Grey Research's FlyCapture SDK with V1 API

Building and Installation

1. checkout pyfly1 project repo

2. to run the examples, you will want pyfly1.pyd (the output of the Cython build process) to be on your python path. So, I recommend adding the src dir of the repo's src dir by creating a file called "default.pth" in your python directory, with this line in it:

   C:\Path\To\Pyfly1Repo\src

   For instance, I have a file called "default.pth" in my C:\Python27 directory, with this one line of content in it:

   C:\Users\Keith\Documents\GitHub\pyfly1\src

3. Install the FlyCapture software

   • install sdk from Point Grey Research
   • copy PGRFlyCapture.dll into pyfly1/src directory

3. python setup.py build_ext --inplace

   (rerun last command whenever cython extension has changed)

Examples

The examples use wx.Python and PIL to show the working module.

1. simple.py is a straightforward demonstration of Chameleon camera access. It shows multiple cameras if they are avaialable
2. heavycalc_naive.py does some deliberately heavy maths on the camera image
3. camera_process, worker_process, heavycalc_pipelined implement a multi processor heavy calculation solution that shows that on a multicore machine zero-mq can improve system performance
