Abstract:
A face recognition apparatus and face recognition method perform face recognition of a face by comparing an image of the face to be identified with target images for identification. The face recognition apparatus includes an image input unit to receive an image of a face to be identified, a sub-image production unit to produce a plurality of sub-images of the input face image using a plurality of different face models, a storage unit to store a plurality of target images, and a face recognition unit to set the sub-images to observed nodes of a Markov network, to set the target images to hidden nodes of the Markov network, and to recognize the presence of a target image corresponding to the face images to be identified using a first relationship between the observed nodes and the hidden nodes and a second relationship between the hidden nodes.
Abstract:
An augmented reality image display system may be implemented together with a surgical robot system. The surgical robot system may include a slave system performing a surgical operation, a master system controlling the surgical operation of the slave system, an imaging system generating a virtual image of the inside of a patient's body, and an augmented reality image display system including a camera capturing a real image having a plurality of markers attached to the patient's body or a human body model. The augmented reality image system may include an augmented reality image generator which detects the plurality of markers in the real image, estimates the position and gaze direction of the camera using the detected markers, and generates an augmented reality image by overlaying a region of the virtual image over the real image, and a display which displays the augmented reality image.
Abstract:
A surgical robot system capable of storing all data transmitted and received in the surgical robot system and a method of controlling the same includes a slave device performing surgery on a patient, a master device controlling a surgical operation of the slave device, an imaging device transmitting a medical image regarding the patient to the slave device and the master device, and a monitoring device comprising a storage module receiving all data transmitted and received among the slave device, the master device, and the imaging device, serializing the received data on a per transmission-time-information basis to generate serial packets, and storing the generated serial packets, and a reproduction module dividing the stored serial packets into a plurality of unit packets and transmitting the unit packets to a device for display.
Abstract:
A robot includes a master device including an input unit, the input unit including a first end effector and a first joint, a slave device configured to be controlled by the master device and including a robot arm, the robot arm including a second end effector, a second joint, and a motor configured to drive the second joint, and a controller configured to calculate a friction compensation value to compensate for friction of the second joint based on a speed of the input unit in response to the input unit being in motion, generate a control signal based on the friction compensation value, and transmit the control signal to the motor configured to drive the second joint.
Abstract:
A robot and method to recognize and handle abnormal situations includes a sensing unit to sense internal and external information of the robot, a storage unit to store the information sensed by the sensing unit, an inference model, a learning model, services providable by the robot, subtasks to provide the services, and handling tasks to handle abnormal situations, and a controller to determine whether an abnormal situation has occurred while the subtasks to provide the selected service are being performed through the learning model in the storage unit and to select a handling task to handle the abnormal situation through the inference model in the storage unit if it is determined that the abnormal situation occur. The robot may recognize and handle abnormal situations even though data other than that defined by a designer of the robot is input thereto due to noises or operational environment.
Abstract:
A medical robot system and a method to control the medical robot system are used to detect position information of a surgical instrument in an incised region, thereby improving the safety of robotic surgery. A surgical instrument may be inserted in a through-hole of a trocar inserted into an incised region of a patient. The medical robotic system includes a surgical instrument position detection apparatus to detect position information of the surgical instrument in the through-hole of the trocar, when the surgical instrument is inserted into the through-hole. The medical robotic system further includes a console to control an operation of a surgical robot having the surgical instrument, based on the detected position information of the surgical instrument.
Abstract:
A support module includes a first rigid body, a space formation body connected to the first rigid body and forming an enclosed space, and a plurality of hard particles located within the enclosed space. When at least a predetermined pressure is applied to the support module such that a volume of the enclosed space is decreased to a predetermined value, the plurality of hard particles and space formation body form a second rigid body. Such a support module may improve the stability of a walking robot, the grip of a gripping structure, or the stability of a load-bearing structure.
Abstract:
A walking robot generates a target trajectory for walking on stairs using a target trajectory used for walking on level ground. A control method controls the robot by generating a target trajectory for walking on stairs using a target trajectory used for walking on level ground. The stairs-walking target-trajectory is generated via simplified calculation using the level-walking target-trajectory.
