Design of mathematical methods and technical means taking three-dimensional information about the object of observation by means of the two-dimensional image

摘要

Abstract: The paper outlines peculiarities of taking three-dimensional information from the two- dimensional image and its technical support. The task of the precise measurement of sizes and the mutual location of components of the object takes place in many fields of science and technique. Common ways of measuring by point touching use a fixed measuring probe. The fixed probe is connected with the measuring system. The free measuring probe can operate without any mechanical connection with the measuring system to transfer coordinate data about bench-mark points of the probe. The benchmark field must be situated within eyeshot of TV sensors. It is enough to compute coordinates of the probe's endpoint. This is a principle difference of the free probe measuring method from common methods. The calculation shows that the represented TV measuring system with the free probe allows the user to define quite precise coordinate information from the object to be measured. !3
