Influence of image registration process disturbances on accuracy of marker coordinates detection

The paper concerns results of the research into accuracy of estimation of position of marker stuck to the valley ball moving in the three-dimensional space. Identification of marker centre of gravity coordinates was carried out on the basis of images burdened with the motion, out-of-focus and confocal blurs. The problem of image reconstruction on the basis of registered noisy image was described with the use of the Fredholm integral equation of the first kind. Phenomena disturbing the process of image registration were modelled with the use of the noise matrix computed as the Kronecker product of matrices modelling disturbances in the horizontal and vertical directions.
