A robot-assisted ultrasound scanning system based on rgb‑d sensors

Abstract

Provided is an auxiliary ultrasonic scanning system of a robot based on an RGB-D sensor. The auxiliary ultrasonic scanning system comprises a Kinect sensor, the robot, an ultrasonic probe, a marker and a host and is characterized in that the Kinect sensor serves as a visual servo system of the robot; the ultrasonic probe is clamped on a mechanical arm of the robot; the marker is fixed onto the ultrasonic probe; the visual servo system of the robot is utilized for synchronously acquiring an RGB color image and a depth image and sending images to the host; the host finishes following processes such as image stitching operation and image three-dimensional reconstruction; according to image pairs acquired by the visual servo system, the marker fixed onto the ultrasonic probe is recognized and positioned by the host; according to a recognition-based positioning result, the position and the posture of the ultrasonic probe are calculated; and the host is used for sending a control instruction to the robot so that the mechanical arm of the robot is controlled to reach at the specified position for carrying out ultrasonic scanning operation. The auxiliary ultrasonic scanning system of the robot based on the RGB-D sensor is advantaged by being reasonable in design, reliable in performance, high in automated degree and detection efficiency and low in cost.
