  • Publication number: 20210158616
    Abstract: A first three-dimensional (3D) model of a target in a 3D space is acquired based on a first two-dimensional (2D) image including the target. A 3D morphing parameter is acquired. The first 3D model is transformed into a second 3D model based on the 3D morphing parameter. First 2D coordinates are acquired by mapping the first 3D model to a 2D space. Second 2D coordinates are acquired by mapping the second 3D model to the 2D space. A second 2D image including a morphed target is acquired by morphing the target in the first 2D image based on the first 2D coordinates and the second 2D coordinates.

    Abstract: The present teaching relates to a method and system for path planning. A target is tracked via one or more sensors. Information of a desired pose of an end-effector with respect to the target and a current pose of the end-effector is obtained. Also, a minimum distance permitted between an arm including the end-effector and each of at least one obstacle identified between the current pose of the end-effector and the target is obtained. A weighting factor previously learned is retrieved and a cost based on a cost function is computed in accordance with a weighted smallest distance between the arm including the end-effector and the at least one obstacle, wherein the smallest distance is weighted by the weighting factor. A trajectory is computed from the current pose to the desired pose by minimizing the cost function.
