An Easy Technique for Fisheye Camera Calibration

We present an easy fisheye camera calibration technique based on a square in the scene plane in this paper. Firstly, aiming at a generic quadrangle including two parallel line segments with the known length ratio, the planar homography between the scene planar including the generic quadrangle and its image is estimated by images of two parallel line segments, then constraints on fisheye camera ...

Camera Calibration Technique using Robust

In this paper we present an algorithm for camera and projector calibration of the liquid crystal range nder using space encoding technique. Because the accuracy of calibration is aaected by noises, and the variation of position or scale of the reference object in the input images, the least-median-of-squares technique is used in our approach, instead of the conventional least squares method. Th...

Optimal Radiometric Calibration for Camera-Display Communication

We present a novel method for communicating between a moving camera and an electronic display by embedding and recovering hidden, dynamic information within an image. A handheld camera pointed at the display can receive not only the display image, but also the underlying message. These active scenes are fundamentally different from traditional passive scenes like QR codes because image formatio...
