Automatic Chessboard Detection for Intrinsic and Extrinsic Camera Parameter Calibration

Automatic Chessboard Detection for Intrinsic and Extrinsic Camera Parameter Calibration

There are increasing applications that require precise calibration of cameras to perform accurate measurements on objects located within images, and an automatic algorithm would reduce this time consuming calibration procedure. The method proposed in this article uses a pattern similar to that of a chess board, which is found automatically in each image, when no information regarding the number...

Reflectance Intensity Assisted Automatic and Accurate Extrinsic Calibration of 3D LiDAR and Panoramic Camera Using a Printed Chessboard

This paper presents a novel method for fully automatic and convenient extrinsic calibration of a 3D LiDAR and a panoramic camera with a normally printed chessboard. The proposed method is based on the 3D corner estimation of the chessboard from the sparse point cloud generated by one frame scan of the LiDAR. To estimate the corners, we formulate a full-scale model of the chessboard and fit it t...

Extrinsic and Intrinsic Sensor Calibration

Sensor Calibration is the process of determining the intrinsic (e.g., focal length) and extrinsic (i.e., position and orientation (pose) with respect to the world, or to another sensor) parameters of a sensor. This task is an essential prerequisite for many applications in robotics, computer vision, and augmented reality. For example, in the field of robotics, in order to fuse measurements from...
