Abstract

The article describes a technique developed for identification of extrinsic parameters of a stereovision camera system for the purpose of image rectification without the use of reference calibration objects. The goal of the presented algorithm is the determination of the mutual position of cameras, under the assumption that they can be modeled by pinhole cameras, are separated by a fixed distance and are moving through a stationary scene. The developed method was verified experimentally on image sequences of a scene with a known structure.

Abstract

To date, only once has the Constitutional Tribunal handed down a verdict concerning the unconstitutionality of a certain maritime legal regulation. This, of course, does not mean that the other legal regulations are constitutional. This paper presents arguments that support this thesis. Primarily, the author analyzes regulations on fisheries of 2004 and those pertaining to the Polish marine areas and the maritime administration from 1991. According to the author, mainly legal regulations regarding financial penalties are constitutionally suspect.

Abstract

The dual core bit-byte CPU must be equipped with properly designed circuits, providing interface between the two processor units, and making it possible to exploit all its advantages like versatility of the byte unit and speed of the bit unit. First of all, the interface circuits should be designed in such a way, that they don’t disturb maximally parallel operation of the units, and that the CPU as a whole works in the same manner as in a standard PLC. The paper presents hardware solutions supporting effective operation of PLC CPU-s. Possibilities of solving problems concerning data exchange between a CPU and peripheral circuits were presented, with a special stress on timers and counters, and also on data exchange between the bit unit and the byte unit. The objective of the proposed solutions is to decrease the time necessary for a CPU to access its peripheries.
