摘要
视频引伸计是一种自动跟踪试样上两标记点的移动来测试样变形的装置,而且与试样不接触。视频引伸计基于光学技术和数码相机技术,给一些特殊试样提供了很好的测量方法。
Video extensometer is a kind of non-contacting device which measures the deformation of specimen by tracking movement between two markers attached to a specimen automatically. Video ex- tensometer is based on optical technology and digital-camera technology, and can supply a good measur- ing solution to some special specimens.
