Abstract: A weakly paired image style transfer method based on a pose self-supervised generative adversarial network, relating to the field of image processing. The method is suitable for style transfer of weakly paired images, different styles of pictures having certain overlap are used to perform model training of an adversarial neural network, so that the model is insensitive to poses and focuses on style learning, and therefore, in an actual application process, a source style can be converted into a target style, but a pose is kept unchanged. In addition, in the model training process of the adversarial neural network, a differentiable pose solver capable of estimating a relative pose of any two images is introduced, a phase correlation algorithm is optimized to be differentiable, and the phase correlation algorithm is embedded into an end-to-end learning network framework to achieve pose estimation.

Abstract: The present disclosure provides a method for performing a non-revisiting coverage task by a manipulator with a least number of lift-offs, and relates to the technical field of manipulator path planning. By explicitly considering lift-offs of an end-effector from a surface of an object due to kinematic constraints when the manipulator performs a task of covering the surface of the object, this method transforms a problem of coverage path design into a problem of sub-cell decomposition and solves the problem to obtain an approach for the manipulator to cover a sub-cell. The method of the present disclosure minimizes the number of lift-offs of the end-effector from the surface of the object when the manipulator performs the coverage task.

Abstract: The present disclosure provides a method for realizing a dynamic running gait of a biped robot on a rough terrain road, which sets a state machine for an entire running cycle to perform a balance control and movement trajectory planning of the robot in each state. At the time that the robot switches from the in-air phase into a landing phase, a SLIP model is used to control the posture balance and landing cushion; and when the robot is stable after landing, an LIP model is used to control a center of mass of the robot to a set height. An in-air phase of the robot in running is generated through movement trajectory planning and state switching of a supporting leg and a swinging leg to realize a running of the robot.
