摘　　要：在机器视觉测量中,由于结构光三维重建技术具有高准确性、低成本、快速、易于操作等优点,而成为一种越来越重要的主动式非接触光学测量方法.其中,结构光投射器——投影仪作为该技术中的主要部件,其标定参数的准确性直接影响系统测量精度.本文总结了近年来经常使用的投影仪标定方法,从标定模型、参数优化方法、参数计算方法和数据获取方法四方面进行阐述,并重点总结了数据获取方法,进而分析和比较了各种方法的优缺点及其应用,最后给出其发展前景.In the machine vision measurement, the 3D reconstruction of structured light has been becoming an important technology for active non-contact optical measurement, due to its high accuracy, low cost, fast process and easy operation. In this technique, projector （i.e. the structured light generator） is a primary component, of which the calibration accuracy directly influences the measurement results. This paper summarizes various commonly used methods for projector calibration, and then addresses the aspects of calibration model, parameter optimization, parameter calculation and data acquisition, focusing on the last one. Additionally, their applications as well as related advantages and limitations are discussed and compared, with development prospects given.
