The Research And Design On CMOS Digital Image Sensor System Acquisition Based On ARM

The ship's engine room is the essential part of shipping, which has collected the majority measuring instrument the equipments and installments. With the rapid development of the network, the communication technology and the electronic manufacture technological level, the modernized ship automaticity is of a high degree as well as the engine room environment and the automatic monitoring level. As some instruments have no interface to communicate with the computer, in order to achieve automatic detection, it is necessary to recognize the numerical characters of the instruments speedily and automatically by digital image processing technique.With the characteristics of slow speed, simple function, big volume and great power consumption, the traditional CCD image gathering system cannot satisfy the need of machine vision application, in particular in some new application domain as the need of the embedded vision and the intelligent monitoring aspect. This article designs and has completed a digital image gathering system by the means of the ARMS3C44B0X processor and CMOS image sensing component. Considering the superiority of the ARM technology and the CMOS image sensing technology, the system combines the image gathering with the imagery processing recognition function in a module and has the advantages of rich function, strong handling ability, nimble connection and convenient expansion. The characteristic system is that it constructs the image gathering hardware platform on the base of S3C44B0X, studies and transplants the Bootloder vectoring procedure and the uClinux operating system and can realize the real-time and multi-duty processing, thus enhances the manageable capacity of the system largely.This dissertation studies a solution to design and implement an embedded image monitoring system that uses CMOS image sensor with low price. This small-sized monitor device can be implemented in one circuit board and has the function of image gathering, image recognition, image storage and image display. The above device can not only be the independent image monitoring instrument, but also be used as an intelligent component in some other application system.
