This wayĪll corners are transferred from camera to projector planeĬompletely independently of each other allowing the full Neighborhood and it is used to translate only one corner. Each local homography is valid only in its Propose to compute a local homography using a small neighbordhoodĪround each corner. With the lens distortion observed in projector lenses. The available corners, we disregard this idea because it cannot cope Not new but other works use a single global homography to translate all To individually translate each checkerboard corner from the camera However, it should beĮasy to build and run on any platform where Qt and OpenCV libraries areĪ novel contribution of this work is the concept of local homographies

The software is tested on Microsoft Windowsħ, Debian GNU/Linux, and Mac OS X Mountain Lion. The software allow the user calibrate a projector-camera system The statue at the front is the targetĪs result of this work, and to make structured-light 3D more widelyĪvailable, a Camera-Projector Calibration software was developed and isĪvailable to download and try. Used a Mitsubishi XD300U DLP projector and a CanonĮOS Rebel XSi camera. The system isĬomposed of a data projector (left) and camera (right). Setup of a structured light system used for 3D scanning. Projector, including the extended pinhole model with radialĪnd tangential distortion coefficients, or even those with more
Makes use of local homographies to reach sub-pixel precision.Īs a result, any camera model can be used to describe the The method relies on an uncalibrated camera and To estimate the image coordinates of 3D points in the projector
Use of a simplified model, neglecting lens distortion, resulting Many of the proposed projector calibration techniques make

Robust calibration methods are wellĮstablished for cameras but, while cameras and projectors canīoth be described with the same mathematical model, it is notĬlear how to adapt these methods to projectors. But suchĪ high precision is only possible if camera and projector areīoth accurately calibrated.
Built with off-the-shelf components,Ī data projector and a camera, they are easy to deploy andĬompare in precision with expensive laser scanners. 3DIMPVT 2012: 3D Imaging, Modeling, Processing, Visualization and Transmission Simple, Accurate, and Robust Projector-Camera Calibration Daniel Moreno and Gabriel Taubin Abstract
