About

J. Piazzi is a leading researcher in robotic vision, whose work has fundamentally advanced the field of visual servoing for mobile and hand-eye systems. Piazzi’s primary contributions center on the innovative use of epipolar geometry to control robot motion, a technique that eliminates the need for precise camera calibration. By exploiting the "auto-epipolar property," Piazzi developed a novel control strategy where the robot is guided by aligning the epipoles—the points where the line connecting two camera centers meets the image plane—between current and desired views. This approach, detailed in seminal papers like "Epipole-Based Visual Servoing with Central Catadioptric Camera" (22 citations), works effectively with both panoramic cameras and standard point features. Piazzi’s work on "Visual Servoing Along Epipoles" and the earlier "Epipole-Based Visual Servoing Using Profiles" has been widely cited, collectively accumulating over 50 citations, and has established a robust framework for tasks ranging from autonomous navigation to precise robotic manipulation. This research is particularly notable for its elegance and practicality, offering a calibration-free solution that is both robust and computationally efficient, making it a cornerstone for students and engineers developing vision-guided robots.
