Artificial markers are successfully adopted to solve several vision tasks, ranging from
tracking to calibration. While most designs share the same working principles, many …

An n-order marker field is a special binary matrix whose n× n subregions are all distinct from
each other in four orientations. It is commonly used to guide the composing process of …

The technique of Projection Mapping, which is useful for merging real-world geometry with
an augmented appearance, is a promising core technology for augmented reality (AR). In …

High-precision pose estimation based on visual markers has been a thriving research topic
in the field of computer vision. However, the suitability of traditional flat markers on curved …

State-of-the-art calibration methods typically choose to use a checkerboard as the
calibration target for its simplicity and robustness. They however require the complete …

The effectiveness of mutation testing depends heavily on the types of faults that the mutation
operators are designed to represent. Thus, the quality of the mutation operators is key to …

The overarching goal of Augmented Reality (AR) is to provide users with the illusion that
virtual and real objects coexist indistinguishably in the same space. An effective persistent …

Accurate camera calibration is a well-known and widely used task in computer vision that
has been researched for decades. However, the standard approach based on checkerboard …

光学复眼在无人系统的精确定位制导, 避障导航等任务中得到了越来越广泛的应用,
其中光学复眼的高精度标定是保障上述任务质量的前提. 通常经典的张氏棋盘格标定法要求光学 …

In this paper, we present a system for high-speed robust monocular tracking (HSRM-
Tracking) of active markers. The proposed algorithm robustly and accurately tracks multiple …
