Study And Design On Intelligent And Digital Monitor System

Today high technology has been applied to the facilities of harbors and ships, it becomes more important on how to using digital Video collecting system and image recognizing on the harbor and ship all over world. The paper will study on these issues.This designing includes three parts: Multi-Inputs Video Collecting System based on PCI-PCI Bridge, Intelligent Keyboard Designing and On-line Image Recognizing and Warning System.The first part is Multi-Inputs Video Collecting System, which base on PCI-PCI Bridge. It realizes that one card can collect multi-input video. At present, four MPEG are integrated on one card which has good performance on extract four inputs video as MPEG format document. The driver software is programmed based on VXD in order to install on Windows.The second part is Intelligent Keyboard Designing, which communicate with computer in double ways, it will help for constructing one complete system. In order to integrate the features of common keyboard and self-defined function the protocol of common keyboard interface is selected, and the self-defined function include error displaying and warning.The last part is that study and design on image recognizing and warning system, it will help to make system working more effectively and Intelligently. A algorithm of Image Recognizing is present and applied on video collecting system which can recognize a man appeared on the camera and give warning. In order to avoid the changing light of environment impact the result of image recognizing, the light value will be fixed to correct value and the noisy of image shall be deleted. The results of recognizing shall be input to database so that the image can be indexed quickly on line.
