Uncalibrated Visual Servo for the Remotely Operated Vehicle [PDF]

, 2017
In this paper, an image-based uncalibrated visual servo scheme is proposed for image tracking tasks in highly disturbed environment, such as a remotely operated vehicle performing observation or investigation influenced by severe underwater current. Under the conditions of unknown target model and camera parameters, the control framework applies the ...
