Camera calibration without metric information using 1D objects
This paper addresses the problem of calibrating a pin-hole camera from images of 1D objects. Assuming a unit aspect ratio and zero skew, we introduce a novel and simple approach t...

Developing Assistant Tools for Geometric Camera Calibration: Assessing the Quality of Input Images
This paper proposes two indicators for predicting the quality of camera model parameters from a set of input images. The first indicator is based on the acutance. It can quickly i...

Calibration of Hand-Held Camera Sequences for Plenoptic Modeling
In this contribution we focus on the calibration of very long image sequences from a hand-held camera that samples the viewing sphere of a scene. View sphere sampling is important...
