New Methods for 3-D Measurement for PTZ Camera Control on a Flat Road Surface

This article presents a schematic application of computer vision technologies to e-learning that is synchronous, peer-to-peer-based, and supports an instructor’s interaction with non-computer teaching equipments. The article first discusses the importance of these focused e-learning areas, where the properties include accurate bidirectional interaction and low cost hardware; system portability and versatile vision technology are emphasized. In the subsequent sections, we present some results aiming to achieve these goals. In particular, we highlight the most recent advancements in the interactive PTZ camera control from both the instructor and remote student. We also illustrated how these results have successfully addressed the challenges.

Self Organizing

The system is composed of Fire center console, wireless control board, wireless multifunctional fire detector and wireless PTZ camera control system. It is based on string-like network topology self-organizing wireless sensor networks, which adopts Simplici TI network protocol that can reduce power consumption of the system. The system uses BP algorithm program for judging whether there is a fire, uses Wireless PTZ camera control system, which is convenient to install, for real-time monitoring the detect area, uses voice module for fire automatic voice alarm to the fire department and uses Micro-Fire GIS to show the location of a fire. BP algorithm program is embedded in wireless multifunctional fire detector. The samples of BP algorithm were derived from the fire detection standard room of the State Key Laboratory of Fire Science of China. The system is low false alarm rate, low cost, fast response and convenient to install.
