Abstract

If a dimensional measurement on an object is to be performed during its non-perturbed motion, a specific approach is needed. In this article we consider length measurement of an object based on photographs of the object during its unperturbed motion. The main obstacle for determining measured length is the parallax which is generated as a convolution of contributions occurring in different parts of a measuring system. The quantitative expressions for the parallax are derived, and applied onto processing of the photos. As a result, we derive in a closed form the algorithm for quantitative estimates of the precisely measured length and accompanied standard deviation.
