Research And Realization Of Image Measurement System Based On DSP

Along with the advance of modern social science and technology level and development,in the field of image measurement system in many ways or got very good application,especially in the public traffic safety management,atmospheric environment monitoring and governance,the Marine environment monitoring and prevention of governance,industrial automation control aspects of production quality,the process of agricultural production management,as well as has already happened or could happen(or will)observe the condition of the monitoring and prevention of analysis and decision,these areas are in the different degree of a generic,miniaturization of image measuring system has certain requirements.Image measuring system using CCD camera technology on the need to measure or monitor image gained by the object or target,according to certain requirements needed to get results after processed by calculation system,due to the use of the camera technology,the system not only can the distance required for different distances measured object or target according to certain requirements for different parameter measurement,but also for the required measurement object or target rea l-time video monitoring and locking of the target image.This paper introduces the principle of image measuring system and its key technologies.First acquired by using CCD image sensor will be converted into electrical signals,optical information and opt ical information in the form of a charge relay,implementation of image acquisition and transmission;Again to get to the characteristics of image information are extracted,the lock or calibration image information of the target signal,the conversion of analog signals and digital signals.Then to digital image signal obtained by using image gray,the image filtering and image correction method of image preprocessing,image denoising and correction;Through feature extraction algorithm and image edge detection algorithm of image edge detection and calibration target;According to the signal pulse calibration method to calculate the size of the target,area,length and distance.On this basis,the design of the image measuring system based on DSP,realize the miniaturization of the image measurement system,and developed the related operating software.Finally respectively using the system to more groups of experiments have been carried out to test image data,basic to achieve the desired effect,to verify the validity and practicability of the image measuring system.
