Description: A fiducial system is a technology that uses specific markers, known as fiducial markers, to facilitate tracking and measurement in computer vision environments. These markers are visual patterns that can be easily detected and recognized by cameras and image processing algorithms. The main feature of a fiducial system is its ability to provide precise references in three-dimensional space, allowing computer vision systems to interpret the position and orientation of objects in relation to these markers. Fiducial systems are particularly useful in applications where high precision in localization and tracking is required, such as in robotics, augmented reality, and industrial automation. Additionally, their implementation is relatively straightforward, as it only requires placing the markers in the environment and calibrating the system to recognize and process the visual information. The relevance of fiducial systems lies in their ability to enhance the interaction between the physical and digital worlds, facilitating the creation of immersive experiences and the automation of complex processes.
