摘要: There are provided an autonomous vehicle, and an apparatus and method for estimating the motion of the autonomous vehicle and detecting three-dimensional (3D) information of an object appearing in front of the moving autonomous vehicle. The autonomous vehicle measures its orientation using an acceleration sensor and a magnetic flux sensor, and extracts epipolar geometry information using the measured orientation information. Since the corresponding points between images required for extracting the epipolar geometry information can be reduced to two, it is possible to more easily and correctly obtain motion information of the autonomous vehicle and 3D information of an object in front of the autonomous vehicle.

摘要: A method of controlling a biped walking robot to balance the robot based on a sensed ground reaction force. In the method, X and Y coordinates are assigned to positions of sensors attached to a sole of a leg of the robot and a corresponding Z coordinate is assigned for at least three of the sensors based on the sensed ground reaction force sensed by at the sensors, respectively. A ground reaction force plane is specified based on the sensed ground reaction force and a normal vector perpendicular to the ground reaction force plane is calculated. A roll angle about an X-axis and a pitch angle about a Y-axis are calculated and an actuator is driven in correspondence to the roll angle and the pitch angle to move a part of the robot to align the normal vector with a reference vector of the gravity direction.

摘要: Provided is a hand/eye calibration method by using a projective invariant shape descriptor of a two-dimensional image. The method includes calculating a projective invariant shape descriptor of a two-dimensional image from at least two images obtained by a camera mounted on a robot hand, at a predetermined time interval, extracting corresponding points between the images by using the projective invariant shape descriptor, calculating a rotation matrix for the corresponding points from translation of the robot hand, calculating translation vector for the corresponding points from translation and rotation of the robot hand, and finding a relation between the robot hand and the camera based on the rotation matrix and the translation vector.
