Fiducial markers robotics

WebFeb 21, 2024 · Planar fiducial markers are a cost-effective solution for addressing labeling and localization challenges. These markers consist of a two-dimensional pattern with an external border and an internal colored code, enabling unique identification. There are three main advantages of using planar fiducial markers. WebAug 24, 2024 · In many applications fiducial markers are required to be planar. This can be due to volume constraints, the need for the prevention of occlusions or blocking of robotic movement, etc. Numerous planar markers exist for robotic systems ( Kato and Billinghurst, 1999; Fiala, 2005; Olson, 2011; Garrido-Jurado et al., 2014 ).
