Nonparametric Calibration for Depth Sensors
نویسندگان
چکیده
In this paper we propose a quick and easy approach to estimate the undistortion function of RGBD sensors. Our method does not rely on the knowledge of the sensor model, on the use of a specific calibration pattern or on external SLAM systems to track the device position. We compute a nonparametric approximation of the undistortion function by applying regression methods to calibration data that can be acquired wherever a sufficiently large planar surface is observed. The procedure is fast, easy and be used on-line. Experimental results show a significant improvement when using undistorted images in applications like mapping.

Depth Data Calibration and Enhancement of Time-of-flight Video-plus-Depth Camera
In this paper, we present a method to calibrate and enhance depth information captured by an infrared (IR)-based time-of-flight video-plus-depth camera called “Kinect camera”. For depth data calibration, we use color and IR images of a chessboard with on-off halogen light sources to calculate camera parameters of the video and IR sensors in the Kinect camera. For depth data enhancement, we intr...
متن کاملA New Calibration Method for Commercial RGB-D Sensors
Commercial RGB-D sensors such as Kinect and Structure Sensors have been widely used in the game industry, where geometric fidelity is not of utmost importance. For applications in which high quality 3D is required, i.e., 3D building models of centimeter‑level accuracy, accurate and reliable calibrations of these sensors are required. This paper presents a new model for calibrating the depth mea...
متن کاملAccurate Intrinsic Calibration of Depth Camera with Cuboids
Due to the low precision, the consumer-grade depth sensor is often calibrated jointly with a color camera, and the joint calibration sometimes presents undesired interactions. In this paper, we propose a novel method to carry out the high-accuracy intrinsic calibration of depth sensors merely by the depth camera, in which the traditional calibration rig, checker-board pattern, is replaced with ...
متن کاملObject Occlusion Detection Using Automatic Camera Calibration for a Wide-Area Video Surveillance System
This paper presents an object occlusion detection algorithm using object depth information that is estimated by automatic camera calibration. The object occlusion problem is a major factor to degrade the performance of object tracking and recognition. To detect an object occlusion, the proposed algorithm consists of three steps: (i) automatic camera calibration using both moving objects and a b...
متن کاملdepth-based nonparametric multivariate analysis and its application in review of new treatment methodology on osteoarthrotic
In this article, first, we introduce depth function as a function for center-outward ranking. Then we present and use half space or Tukey depth function as one of the most popular depth functions. In the following, multivariate nonparametric tests for location and scale difference between two population are expressed by ranking and statistics based on depth versus depth plot. Finally, accord...
