摘　　要：热态锻件尺寸的传统的手工在线测量耗时、精度不高,大大降低了生产效率,增加了生产成本,为此,本文对热锻件尺寸光学无接触在线测量方法的合理性进行了探讨,分析了可见光成像双目立体视觉测量、红外双目立体视觉测量、基于Gray编码和移相法的结构光双目立体视觉测量、激光三维扫描测量四种方法的原理、优缺点、适用场合、国内外现状及其他相关国内外现状,从而为工业实际中热锻件尺寸光学无接触在线测量方法的选择奠定良好的基础。The rationality of optical non-contact online measuring methods of the size for hot forgings has been discussed in the text. The principles, advantages ＆ disadvantages, applications, and foreign ＆ domestic status of four methods including visible imaging binocular stereo vision measurement, IR binocular stereo vision measurement, structured light binocular stereo vision measurement based on Gray code and phase shift method and three-dimensional laser scanning measurement have been analyzed. It provides good foundation for selecting the optical non-contact online measuring methods of the size for industrial hot forgings.
