This paper presents through of the principle of laser triangulation a technique to acquisition data from an environment. The prototype can discover obstacles or objects in a unknown environment. Using a light source (laser) and very simple but efficient scanning unit is possible determinate distances and angles of any point on object in environment based in(More)
At last decade many approaches for non-contact measurement techniques for object surfaces and approaches for 3D object recognition have been proposed; but often they still require complex and expensive equipment. Not least due to the rapidly increasing number of efficient 3D hardware and software system components, alternative low cost solutions are in(More)
A fast frequency measurement method based on the pulse coincidence of two regular independent pulse trains and rational approximations in the number theory is presented. A numeric condition derived from number theory to stop the measurement process is deduced. This measurement method has application in many practical tasks of Mechatronics and(More)
It is described a different way to make a frequency counting process that helps to improve fast resolution of an output parameter of a typical automotive frequency domain sensor. After a brief explanation about FDS, specifically SAW sensors work, it is explained a Principle of rational approximation and it is shown its application for fast registration of(More)
Many approaches for remote measurement techniques for object surfaces and approaches for 3D object recognition have been proposed; but often they still require complex and expensive equipment. Not least due to the rapidly increasing number of efficient 3d hard- and software system components, alternative low cost solutions are in great demand. We propose(More)
In this paper, a novel method of frequency counting of signals coming from automotive sensors is presented. The present method helps to improve fast resolution of output parameters of typical automotive frequency-domain sensors (FDS). Controlling the electromechanical systems in today's cars is a task that requires a high processing speed. The method(More)
The problem of optimal kinematic control of an excavator manipulator motion for a given trajectory is considered. The minimizing of the quadratic functional of the angles associated with the respective weights as the optimality criterion is adopted. The efficiency of proposed method is confirmed by numerical example. Offered laser Technical Vision System(More)
The new design creation of technical vision system for any automatic mobile object is offered. The new technical means for "technical vision system" realization are proposed.

The phase shift of coherent signals and the time intervals can be measured with the method of coincidences of electrical pulses. The results are automatically obtained and represented like simple fractions. These fractions are rational approximations of the unknown parameter, which generally is an irrational number. Such approximations can be represented(More)
The technical vision principle of a mobile robot for working in a complex landscape or on a crosscountry terrain is presented. Issues of principle design, functioning and interaction of units and elements of the system are described. The mathematical tools for processing the signal detection, and also for determination of distances and angular measures are(More)
