Indoor Scene Point Cloud Registration Algorithm Based on RGB-D Camera Calibration

Abstract: With the increasing popularity of RGB-depth (RGB-D) sensor, research on the use of RGB-D sensors to reconstruct three-dimensional (3D) indoor scenes has gained more and more attention. In this paper, an automatic point cloud registration algorithm is proposed to efficiently handle the task of 3D indoor scene reconstruction using pan-tilt platforms on a fixed position. The proposed algorithm aims to align multiple point clouds using extrinsic parameters of the RGB-D camera obtained from every preset pan-tilt co… Show more

“…RGB and IR images will not be spatially registered since the optical characteristics of the sensors and their relative position and orientation differ from one another. This will be another barrier to overcome since the lack of information between RGB and thermal cameras makes it difficult to perform an extrinsic calibration using typical techniques [20][21][22][23][24].…”

“…The purpose of camera calibration is to acquire the parameters of the camera imaging model, including the intrinsic parameters that characterize the intrinsic structure of the camera and the optical characteristics of the lens and the external parameters that describe the spatial pose of the camera [18]. Moreover, camera calibration methods can be roughly divided into four categories: laboratory calibration [19], optical calibration [20], on-the-job calibration [21], and self-calibration [22]. The calibration field in laboratory calibration is generally composed of some control points with known spatial coordinates, and it can also be subdivided into a 2D calibration field and a 3D calibration field.…”

“…The introduction of low-cost RGB-D cameras created an opportunity for 3D reconstruction of scenes to be performed at consumer-level. The increasing popularity of these sensors promoted the research of their use to reconstruct 3D indoor scenes [14][15][16]. Their manoeuvrability, permitting hand-held operation and allowing the user to get closer to parts of the scene and capturing them from different angles, proves to be an advantage in indoor environments with high probability of object occlusion, when compared with fixed high resolution scanners, which usually require more space and fixed poses to operate.…”
