Accuracy Verification Tool
The Accuracy Verification Tool (AVT) is a product designed by Atracsys. It allows the user to check
the trueness of an optical tracking device. It consists of an artefact, an acquisition software, as well
as a processing software running on Atracsys servers, in case a detailed report is asked for..
aCn
The fusionTrack 500 is able to externally provide different signals via its EIO port. These signais can
be the exposure of the tracker; the strobe of the IR LEDs; a user trigger or the device timestamp .
A UART communication allows to confgure which signals are confgured on the EIO lines. To easily
access these signals, the atracConnect (aCn) board can be used. The full documentation of the aCn
is available in the doc/ folder of the SDK.
API
Application Programming interface. It is a set of routines, protocols, and tools for building software
applications.
Fiducial
Simplest element (sphere covered with reflective material, sticker with reflective material, reflective
glass sphere, IR-LED) detected by the optical tracking system, and reconstructed as a three-dimensional
point (e.g.
(
x, y, z
)
coordinates).
GUI
Graphical User Interface, this is a type of interface that allows users to interact with electronic devices
through graphical icons and visual indicators such as secondary notation, as opposed to text-based
interfaces, typed command labels or text navigation.
IGS
Image-Guided Surgery. This is the general term used for any surgical procedure where the surgeon
employs tracked surgical instruments in conjunction with preoperative or intraoperative images in
order to guide the procedure.
JSON
In computing, JavaScript Object Notation or
is an open-standard file format that uses human-
