Temporal and Spatial Denoising of Depth Maps
Sensors, 2015 This work presents a procedure for refining depth maps acquired using RGB-D (depth) cameras. With numerous new structured-light RGB-D cameras, acquiring high-resolution depth maps has become easy. However, there are problems such as undesired occlusion,

A Primal-Dual Framework for Real-Time Dense RGB-D Scene Flow [PDF]
, 2015 This paper presents the first method to compute dense scene flow in real-time for RGB-D cameras. It is based on a variational formulation where brightness constancy and geometric consistency are imposed.

Robust 3D Reconstruction With an RGB-D Camera [PDF]
IEEE Transactions on Image Processing, 2014 We present a novel 3D reconstruction approach using a low-cost RGB-D camera such as Microsoft Kinect. Compared with previous methods, our scanning system can work well in challenging cases where there are large repeated textures and significant depth missing problems.

Real-time RGB-D camera relocalization [PDF]
2013 IEEE International Symposium on Mixed and Augmented Reality (ISMAR), 2013 We introduce an efficient camera relocalization approach which can be easily integrated into real-time 3D reconstruction methods, such as KinectFusion. Our approach makes use of compact encoding of whole image frames which enables both online harvesting of keyframes in tracking mode, and fast retrieval of pose proposals when tracking is lost.

Reduced Calibration Strategy Using a Basketball for RGB-D Cameras
Mathematics, 2022 RGB-D cameras produce depth and color information commonly used in the 3D reconstruction and vision computer areas. Different cameras with the same model usually produce images with different calibration errors. The color and depth layer usually requires

Fast capture of textured full-body avatar with RGB-D cameras [PDF]
, 2016 We present a practical system which can provide a textured full-body avatar within three seconds. It uses sixteen RGB-depth (RGB-D) cameras, ten of which are arranged to capture the body, while six target the important head region.

EXTRINSIC RGB-D CAMERA CALIBRATION FOR LEGGED ROBOTS [PDF]
Field Robotics, 2011 This paper describes a method to identify the extrinsic parameters of RGB-D cameras mounted on legged robots. Since the calculation of the parameters is based on the detection of the robots feet in the camera images, no special calibration objects are required. Therefore the method is simple to use and can even be applied automatically.

Robust alternating optimisation for extrinsic calibration of RGB‐D cameras
Electronics Letters, 2019 RGB‐depth (RGB‐D) cameras are widely used for 3D reconstruction or human–computer interaction. To simultaneously acquire colour and depth images of an object in widely separated viewpoints, multiple RGB‐D cameras are required.

A Robust Calibration Method for Consumer Grade RGB-D Sensors for Precise Indoor Reconstruction
IEEE Access, 2019 RGB-D cameras, which can be attached to any mobile device and work under different operation platforms (e.g., iOS, Android, and Windows), have great potential for indoor 3D modeling and navigation due to their low cost and small size.
