As part of the Nanorobotics project a TEM vision software was developed. The software makes use of a JEOL 3010 transmission electron microscope with a TVIPS FastScan-F114 camera which is an IIDC/DCAM-compatible firewire camera. The nano-indenter is controlled by a Nanomagnetics SPM controller (the old version of the controller can be accessed with a PCI-DIO24 card).
The software runs under GNU/Linux and it makes use of Damien Douxchamps' libdc1394 to access the camera and Warren Jasper's PCI-DIO24 driver to access the PCI-card which interfaces with the SPM controller.
The software was implemented in Ruby using Qt4-QtRuby, HornetsEye, libJIT, and a custom Ruby-extension to access the SPM controller via the PCI-DIO24 card. Distributed Ruby and multiple processes were used to work around the problem that Ruby-1.8 does not offer native threads.
The vision algorithms are configured using a separate program and the configuration is saved in a file using Ruby marshalling. A plugin-based architecture, which accepts plugins for recognition and tracking, was implemented which allows one to select and configure Normalised Cross-Correlation, Lucas-Kanade tracking, or Connected Component Analysis.

The software can be downloaded here: visiongui-0.2.tar.bz2
The software is implemented in Ruby. It uses HornetsEye (current development of version 0.32) and Qt4-QtRuby.
[edit] Future Work
Possible future work is
- port to Ruby-1.9 which has native threads
- integrate serial-port interface of JEOL TEM
- access USB-controls for shutter and gain of the TVIPS camera
- feature-based recognition and tracking (less sensitive to brightness changes)
- offset- and gain-compensation for camera image
