Robust localization is critical for the navigation and control of mobile robots. Global
Navigation Satellite Systems (GNSS), Visual-Inertial Odometry (VIO), and Simultaneous …

Augmented reality (AR) allows to seamlessly insert virtual objects in an image sequence. In
order to accomplish this goal, it is important that synthetic elements are rendered and …

Fiducials are artificial features with a variety of uses in computer vision such as object
tracking and localization. We propose the idea of flexible tag layouts for visual fiducial …

This paper introduces recent progress on techniques of object detection and pose tracking
with a monocular camera for augmented reality applications. To visually merge a virtual …

Traditional methods of delivering construction information, relying on paper-based shop
drawings, specifications, and verbal instructions, often lead to increased mental workload …

Current fiducial marker detection algorithms rely on marker IDs for false positive rejection.
Time is wasted on potential detections that will eventually be rejected as false positives. We …

Fiducial markers have been playing an important role in augmented reality (AR), robot
navigation, and general applications where the relative pose between a camera and an …

Using fiducial markers ensures reliable detection and identification of planar features in
images. Fiducials are used in a wide range of applications, especially when a reliable visual …

In this paper, we analyzed the accuracy and precision of AprilTag as a visual fiducial marker
in detail. We have analyzed error propagation along two horizontal axes along with the …

Fiducial markers such as QR codes, ArUco, and AprilTag have become very popular tools
for labeling and camera positioning. They are robust and easy to detect, even in devices …
