论文摘要
基于最新的飞行时间（TOF）3D传感器的横向和深度分辨率较差。在这项工作中，我们介绍了一种新型的传感器概念，该概念可提供基于TOF的3D测量现实对象，其深度精度最高35微米，并且在最先进的CMOS/CCD摄像机的天然传感器分辨率下（最高几兆像素）。与其他连续波振幅调节的TOF原理不同，我们的方法利用波长多样性来对具有粗糙或镜面表面的宏观对象进行干涉表面测量。基于此原理，我们介绍了原型传感器的三个不同实施方案，利用了三个不同的传感器体系结构。
State-of-the-art time-of-flight (ToF) based 3D sensors suffer from poor lateral and depth resolutions. In this work, we introduce a novel sensor concept that provides ToF-based 3D measurements of real world objects with depth precisions up to 35 micrometers and point cloud densities at the native sensor-resolutions of state-of-the-art CMOS/CCD cameras (up to several megapixels). Unlike other continuous-wave amplitude-modulated ToF principles, our approach exploits wavelength diversity for an interferometric surface measurement of macroscopic objects with rough or specular surfaces. Based on this principle, we introduce three different embodiments of prototype sensors, exploiting three different sensor architectures.
