摘　　要：编码技术是决定结构光三维测量准确度、分辨率和可靠性的关键因素.时间编码相对于空间编码和直接编码而言,具有高准确度、高分辨率的优点,是结构光三维测量技术的发展趋势.时间编码方法分为二灰度级编码、多灰度级编码和组合编码三类,本文综述了结构光时间编码技术近二十年的发展和应用情况,并指出该技术今后发展趋势.Encoding technologies is the key factor to decide the accuracy, resolution and reliability of 3d measurement based on structured light. Relative to space encoding and direct encoding, time encoding has advantages of high accuracy and high resolution, and it is the development tendency of 3d measurement based on structured light. Time encoding has three kinds, two gray level,multi-gray level and integrated encoding. This article reviews the development and application of structured light time encoding technologies in recent two decades. It also indicates the development tendency in future.
