摘　　要：综述了基于相位辅助的三维数字成像与测量的核心技术。以相机模型为基础,建立了三维数字成像系统模型和三维测量网模型,并介绍了相关的标定技术。在主动立体视觉的理论框架下,综述了相位提取、相位展开、对应点搜索等单视点深度像重建的关键技术。介绍了深度数据后处理技术,其中包括多视点深度像的匹配、融合和简化的代表性算法。同时,对系统标定、深度像重建、深度数据后处理等各个环节对整体测量精度的影响分别进行了论证。This paper surveys a cutting-edge technology based on phase-aided three dimensional imaging and metrology（PA3DM）.The imaging modality and the calibration of the PA3DM and an optical measurement network based on multiple PA3DM node sensors are formulated,which are closely related to the camera model.The phase extraction and phase unwrapping as well as the homologous point-pair searching for range image reconstruction are discussed under a framework of active stereo imaging.Typical post-processing techniques,including range image registration,integration,and simplification are also discussed in detail.Meanwhile the error sources impacting on the accuracy of PA3DM-based imaging and metrology system are also analyzed from point of view of each crucial step such as system calibration,range image reconstruction and post-processing.
