摘要
陶瓷、古文物以及金属工件等高反光物体表面的三维形貌测量在各个领域有大量的需求和应用。由于表面反射率变化范围较大以及相机灰度范围有限等问题,传统的条纹投影方法不能正确地测量高反光表面的三维形貌。综述了高反光表面三维形貌测量技术的国内外研究现状、应用领域和未来发展方向。首先,根据所采用原理和测量方法的不同,将现有的高动态范围三维形貌测量技术分为下述六类进行详细的介绍:多重曝光法、投影图案强度法、偏振滤光片法、颜色不变量法、光度立体技术以及其他技术。然后,详细的比较了各种技术的优缺点并归纳其适应性分析。最后,总结了高反光表面三维形貌测量技术的应用领域并展望了该技术的未来研究方向。基于文中综述的内容,使用者可根据不同的应用需求和测量条件选择相应的最佳三维测量方法,进而更精确的重建高反光表面的三维形貌。
Abstract
There are a large number of three-dimensional (3D) shape measurement requirements and applications for objects with shiny surfaces, such as ceramics, ancient artifacts, and metal workpieces. However, the traditional fringe projection method cannot accurately measure shiny surfaces due to the large range of reflectivity of the objects with shiny surfaces and the limited maximum gray level of the camera. This paper reviewed the recent developments, application fields and future research directions of high dynamic range 3D shape measurement technologies of shiny surface. First, according to the principle and measurement method, the existing 3D measurement technologies of high dynamic range were divided into the following six categories: multiple exposures methods, projected patterns intensities adjusting methods, polarizing filters methods, color invariants methods, photometric stereo technology and miscellaneous technologies. Then, the advantages and disadvantages of these technologies were compared in detail and their adaptability was summarized. Finally, this paper summarized the application fields of shiny surfaces in 3D shape measurement technology and prospects the future research directions. It can provide users with the optimal 3D measurement method according to the different application requirements and the different measurement conditions, eventually the 3D shape of shiny surfaces can be reconstructed more accurately.
