The horoptor and active cyclotorsion
نویسنده
چکیده
When a particular 3 0 point is fixated b y a robotic stereo system different portions of the world are brought into interocular alignment. This region is known as the horoptor. Purposeful modifications to the binocular geometry can be used to bring different regions of three-space closer to the horoptor: Camera pan and tilt define the rough structure of the horoptor, while camera torsion can be used to change its local shape. Theoretical and empirical results suggest that for binocular vision tasks (i) it is important to understand the region o f three space that contains the horoptor curve and (ai) it is possible to control this shape in an active way so as to simplify certain binocular tasks.

متن کاملMinimising residual aberration in the presence of cyclotorsion uncertainty in refractive surgery
METHODS: Assuming that cyclotorsion error can be estimated and compensated for with a certain level of uncertainty, we formulate a function to modify the wavefront error in order to minimize the residual aberration magnitudes due to cyclotorsion measurement uncertainty. A modal optimum nomogram factor is computed for minimization of the residual aberration for each Zernike mode. We also calcula...
