Abstract


With the continuous development of measurement techniques , modern industrial requirements of the scantlings detection accuracy and fast growing . Image measurement technique as a non-contact measurements , with its advantages of high-precision , high-speed , high efficiency , high degree of automation , good to meet the demand for industrial inspection field , is widely used in the production process . This article is from the axis symmetric component geometry detection problem , and strive to build a set of image measurement system for engineering applications . This paper first describes the theory of image measurement technology on the status quo and development trends in the technology field . According to the testing requirements of practical engineering problems , on the basis of analysis of the cylinder parameters measuring principle , the design the cylinder size measuring system ( including hardware and software systems ) , raised the height of the cylinder , the diameter of the top of the roundness error base diameter and the thickness of the measurement program. Second, to analyze the hardware components of the system : a lighting system and an image sensor system . And part of the selection method . Camera calibration and image processing algorithms in the software system for the project requirements . Tsai calibration method based on the main point coordinates and aspect ratio calibration , a plane calibration method . And in the process of analysis of the roundness error of the least squares method , the introduction of intermediate variables , thereby greatly reducing the computational complexity , improve running speed . Finally, three models of the cylinder for the detection of objects , the system and method of use of this measurement , the completion of its size parameter detection experiments , and the measurement error to be analyzed , the experimental results show that the detection accuracy of the system to achieve the requirements of the project .
