“…To make robots more intelligent and flexible, they are often equipped with vision sensors as tools for interacting with the outside world. In recent decades, robotic visual servoing has been fully researched and widely used in various areas, such as robotic production logistic [1], robotic service [2,3], robotic navigation and exploration [4,5]. According to the different feedback information from the camera, the visual servoing system can be divided into image-based visual servoing [6,7], position-based visual servoing [8,9], and hybrid visual servoing [10,11].…”
