摘　　要：本文对投影映射技术近十年发展现状进行综述,介绍了与投影映射技术相关联的算法、硬件的最新发展状况。总结了投影映射中核心的三维几何校准算法发展状况,包括各类自校准和半自校准算法的研究进展。与此同时,本文介绍了动态投影映射的研究进展,包括刚体投影和非刚体投影的发展。最后,本文从硬件发展的角度,给出了当前投影机硬件在解决动态范围、刷新率、空间分辨率、景深、视图相关性和颜色空间等领域问题的进展和存在的问题。This latest report covers the latest advances in algorithms,hardware within pojection mapping.This article summarizes new improvements to simplify the 3D geometry calibration task,which can now be done interactively or automatically and reliably using self-calibration methods,and then introduces research advances in dynamic projection mapping,including rigid dynamic projection and non-rigid dynamic projection.Improvements in radiation calibration and compensation and the elimination of global illumination effects are then summarized.Finally,from the perspective of hardware development,computational display methods are introduced to overcome the technical limitations of current projection hardware in terms of dynamic range,refresh rate,spatial resolution,depth of field,view relevance,and color space.These technologies help create new application areas related to projection-based spatial enhancement.
