Kinect for Xbox 360,简称 Kinect,是由微软开发,应用于 Xbox 360 主机的周边设备。它让玩家不需要手持或踩踏控制器,而是使用语音指令或手势来操作 Xbox 360 的系统界面。它也能捕捉玩家全身上下的动作,用身体来进行游戏,带给玩家“免控制器的游戏与娱乐体验”。 2009 年 6 月 1 日微软于 E3 游戏展中公布名为“Project Natal”(诞生计划)的感应器,它能够捕捉使用者的肢体动作,或是进行脸部辨识。感应器也内建麦克风,可以用来识别语音指令。此感应器兼容于所有 Xbox 360 主机,玩家只需新购此感应器就可直接使用。 2010 年的 E3 电玩展,微软宣布 Project Natal 的正式名称为“Kinect”,并预计在 2010 年 11 月 4 日于美国上市,建议售价 149 美金。台湾则在2010 年 11 月 20 日上市。

Obtaining high-quality 3D reconstructions of room-scale scenes is of paramount importance for upcoming applications in AR or VR. These range from mixed reality applications for teleconferencing, virtual measuring, virtual room planing, to robotic applications. While current volume-based view synthesis methods that use neural radiance fields (NeRFs) show promising results in reproducing the appearance of an object or scene, they do not reconstruct an actual surface. The volumetric representation of the surface based on densities leads to artifacts when a surface is extracted using Marching Cubes, since during optimization, densities are accumulated along the ray and are not used at a single sample point in isolation. Instead of this volumetric representation of the surface, we propose to represent the surface using an implicit function (truncated signed distance function). We show how to incorporate this representation in the NeRF framework, and extend it to use depth measurements from a commodity RGB-D sensor, such as a Kinect. In addition, we propose a pose and camera refinement technique which improves the overall reconstruction quality. In contrast to concurrent work on integrating depth priors in NeRF which concentrates on novel view synthesis, our approach is able to reconstruct high-quality, metrical 3D reconstructions.
