Camera Parameter Estimation Method Using Infrared Markers for Live TV Production

We have developed a robust method for estimating camera parameters for live TV production based on infrared markers whose feature-point extraction is simple and two-dimensional color histogram matching that considers the effects of specular reflection due to lighting. We first explain the principle of the proposed technique. We then present the results of a basic experiment for evaluating the accuracy of marker identification and the results of an image-compositing experiment using estimated camera parameters. We show that the proposed technique is effective based on those results.
