The computer vision techniques adopted would not have been practical had the genetic algorithms not been able to solve these constraints. This paper focuses on the design and evolution of the markers, the computer vision aspects of reacTIVision are documented else- where. 1. Introduction The ...
Chilitags are a C++ cross-platform software library for the detection and identification of 2D fiducial markers (a.k.a. tags). Their purpose is to be printed and placed on objects from the real world, to form the basis of Robotics or Augmented Reality (AR) applications. Using a camera, ...
Fiducial markers3D reconstructionSimultaneous localization and mappingSLAMIn this paper, we present an incremental structure from motion (SfM) algorithm that significantly outperforms existing algorithms when fiducial markers are present in the scene, and that matches the......
摘要: We propose an algorithm for generating configurable marker dictionaries.We derive the maximum theoretical inter-marker distance.A method for automatically detecting the markers and correcting errors is proposed.A solution to the occlusion problem in augmented reality applications is shown....

Among the several fiducial marker systems proposed in the literature, those based on square markers have gained popularity, especially in the augmented reality community [10], [11], [12]. The reason why is that they allow us to extract the camera pose from their four corners, given that the...
