Optometric-lab: a Stereophotogrammetry Tool for Eye Movements Records
In this paper as showed a non-invasive 3D eye tracker
for optometry clinical applications. Measurements of biomechanical
variables in clinical practice have many font of errors associated with
traditional procedments such cover test (CT), near point of
accommodation (NPC), eye ductions (ED), eye vergences (EG) and,
eye versions (ES). Ocular motility should always be tested but all
evaluations have a subjective interpretations by practitioners, the
results is based in clinical experiences, repeatability and accuracy
don-t exist. Optometric-lab is a tool with 3 (tree) analogical video
cameras triggered and synchronized in one acquisition board AD.
The variables globe rotation angle and velocity can be quantified.
Data record frequency was performed with 27Hz, camera calibration
was performed in a know volume and image radial distortion
adjustments.
