Fractal Markers

News:Fractal Markers!

Fractal markers are a new concept of marker, which is composed of several fiducial square markers of different size inside. Unlike traditional fiducial markers, the structure of this marker can be detected from a large number of distances, as well as solve problems of partial or total occlusion of the marker.

The features of this marker, together with the tools developed make it a powerful tool for camera pose estimation in a large number of applications such as robots, unmanned vehicles and augmented reality.

Fractal Marker is integrated inside ArUco's libraries, allowing a fast, robust and precise detection of the markers. ArUco is a widely used OpenSource library for detecting squared fiducial.
