ChESS - Quick and Robust Detection of Chess-board Features
This work addresses a specific need in camera calibration and 3D reconstruction by providing a robust detector for chess-board features, though it is incremental as it builds on existing detection tasks.
The paper tackles the problem of localizing chess-board vertices in computer vision by introducing the ChESS detector, which is designed to be fast, accurate, and robust against noise, lighting, and contrast issues, with evidence showing its efficiency and accuracy in simulations and 3D reconstruction experiments.
Localization of chess-board vertices is a common task in computer vision, underpinning many applications, but relatively little work focusses on designing a specific feature detector that is fast, accurate and robust. In this paper the `Chess-board Extraction by Subtraction and Summation' (ChESS) feature detector, designed to exclusively respond to chess-board vertices, is presented. The method proposed is robust against noise, poor lighting and poor contrast, requires no prior knowledge of the extent of the chess-board pattern, is computationally very efficient, and provides a strength measure of detected features. Such a detector has significant application both in the key field of camera calibration, as well as in Structured Light 3D reconstruction. Evidence is presented showing its robustness, accuracy, and efficiency in comparison to other commonly used detectors both under simulation and in experimental 3D reconstruction of flat plate and cylindrical objects
