Real time Particle Tracking Velocimetry using FPGA on the camera

This is an upgrade of the open source 3D-PTV software (http://ptvwiki.netcipia.net) from ETH Zurich that works with the RAW data obtained using the MC1324 Sobel camera through GigE. MC1324 is operated through Coyette or GenDEV applications, produces RAW binary files per image (at 500 frames per second). The files include only the objects of identified particles. More information is available from Mark Kreizer's manual on the wiki site of the Turbulence Structure Laboratory

Installation:

1. Get ActiveTCL, install it in C:\Tcl (if different directory is used, compilation is necessary)
2. Get Sobel_2DPTV software from the http://ptvwiki.netcipia.net
3. Install in any directory, e.g. C:\PTV\Software\Sobel_2DPTV
4. Change the path to this directory in the ptv.tcl file, e.g. set auto_path "C:/PTV/Software/Sobel_2DPTV . $auto_path" (note the / slash direction)

Usage:

1. Run the software by double-clicking the start.bat

2. The Sobel mode pre-requisites are as follows: a) RAW files should appear in /img directory b) RAW files are numbered as: 00009197.raw, i.e. 8 digits and then #.raw c) /res directory should exist d) software will use RAW files, write _targets file (useful for the test) in the /img directory and rt_is.*, ptv_is.* and added.* files in the /res directory

3. Use: a) Start button b) Sequence -> Sequence with Sobel c) Tracking (with or without display, forward or backward). Don't use Sequence/Tracking or shaking.

4. Add-ons a) In Matlab directory there are few codes that help for testing: txt2image.m will generate images in the same directory from _targets files read_write_targets.m makes some sorting, not necessary after PTV, only if _targets are produced manually by raw2targets.m
