摘要： A system and method for constructing a 3D scene model comprising 3D objects and representing a scene, based upon a prior 3D scene model. The method comprises the steps of acquiring an image of the scene; initializing the computed 3D scene model to the prior 3D scene model; and modifying the computed 3D scene model to be consistent with the image. The step of modifying the computed 3D scene models consists of the sub-steps of comparing data of the image with objects of the 3D scene model, resulting in associated data and unassociated data; using the unassociated data to compute new objects that are not in the 3D scene model and adding the new objects to the 3D scene model; and using the associated data to detect objects in the prior 3D scene model that are absent and removing the absent objects from the 3D scene model. The present invention may also be used to construct multiple alternative 3D scene models.

摘要： Disclosed is a system and method for computing ultrasound 3D elasticity images. The method includes acquiring ultrasound RF data in a rest state, in which substantially no pressure is applied to a tissue medium, and acquiring ultrasound data in a stressed state, in which pressure is applied to a tissue medium having an aberration, and computing a measured displacement image from the two RF data sets. The method also includes computing an initial estimated displacement image, which is derived from a 3D elasticity model. The method further includes computing an optimization loop, wherein the initial estimated displacement image is adjusted to converge on the measured displacement image. The optimized estimated displacement image is then segmented and superimposed over the rest state ultrasound image. Further, the original 3D elasticity model is adjusted to match the optimized estimated displacement image.

摘要： A system and method for automatically computing desirable palm grasp configurations of an object by a robotic hand is disclosed. A description of the object's surface is obtained. A grasp configuration of a robotic hand comprising a palm and one or more fingers is selected, which specifies a hand configuration and joint variables of the hand, and a plurality of contact points on the object's surface for the palm and fingers. The coefficient of friction at each of the contact points is determined, and a description of one or more external wrenches to which may apply to the object is acquired. The ability of the robotic hand to hold the object against the external wrenches in the selected configuration is then computed. In some embodiments, a plurality of grasp configurations may be compared to determine which are the most desirable. In other embodiments, the space of hand configurations, or the smaller space of palm contact configurations, may be searched to find the most desirable grasp configurations.
