Abstract.
The problem of determining the position of a fast
moving object in a noisy image obtained using the CCD is considered. Application of Radon
transform allows to select the motion path. Fourier transformation of
autocorrelation along the trajectories obtained allows to find the speed in the
image plane. Using this speed and taking into account features of CCD it is
possible to construct the motion
model. Maximum correlation is the initial position of the object. A model of
the system is worked-out, which permits to obtain estimates of achievable accuracy of the object
location at different signal/noise ratios.
