A Research For The Technology Of Positions Dimensional Inspection Based On Matrix CCD

This article introduces the application of area CCD in untouched measurement of industry, at present, measurement technology is moving to high precision, high efficiency and automation.The stability of artillery body in the lauch process affects lauch precision directly, therefore it is necessary of the stability detection in the lauch process to improve the artillery lauch precision and analyse the reasonability of artillery design. At present, there are two major methods of the stability detection , such as the mechanical methods of stroke needle and stroke board , but the precision is low and the technology is backward , which can only detect the maximum displacement and can not offer displacement - time curve, can not satisfy detection requirement. In order to complete each task of detection better and improve the level of dynamic dectection technology, this paper adapt the high-tech mean such as photoelectric detection technology to realize the non-contact measure of artillery body stability.In this paper , the overall design scheme and the option of light source have been analysed and discussed , the composition and overall structure of system have been discussed in detail , the photoelectric detection technology principle and Charge Coupled Devices(CCD) principle have been analysed . Optical image system and computer control and data processing electronic system have been designed, the major source of error and the influence of it to the systematic detection precision. has been analysed. Through the theory analysis, this system achieved the anticipated precision.
