Modern CCD cameras are usually capable of a spatial accuracy greater than 1/50 of the pixel size. However, such accuracy is not easily attained due to various error sources that c...

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...

Inspired by Zhang's work, a new easy technique for calibrating a camera based on circular points is proposed. The proposed technique only requires the camera to observe a new...
