Magnetic Materials, Geometric Dimensions Automated Image Measurement System

The article studied to make Image measuring technology use of automatical measurement of magnetic materials dimension in factories and basic principles and methods of this technology application, We set up automatical measuring system of magnetic materials dimension and studied the hardware part and the soft part of this system.According to the requirements and targets of measurement system, We took CCD as image sensor, combining lens, image collection card, PCI-1761I/O, air compressed machine etc to constitute the hardware of whole Image measuring system. The software included two module parts, which is digital image collection and processing and measurement of magnetic materials dimension parameters. Image collection and processing part used image processing technology in this item according to characters of image collected. Measurement of parameters part took two kinds of material that the cross section is cirque and the profile is arcograph as example and introduced theory and implement of measurement. The program was debugged successly based on Visual C++. We built a test equipment to study the hardware part performance and got primary results. Simultaneously, the software part was given accidence test result through a fixed scale way.That magnetic materials dimension was measured through image measuring technology not only could solve problem brought about the traditional checking that checking speed is slow and is influenced by the checking person easily, but could achieve automatical measurement quickly and exactly. So it made some foundations for improveing production efficiency. The results we studied gave some reference for applications and popularize of image measuring technology.
