Abstract: A method for registering a two-dimensional image data set of a body of interest with a three-dimensional image data set of the body of interest is discloses herein. The method includes the following steps: generating a first reconstructed image from the three-dimensional image data set with a first spatial parameter; calculating a reference similarity value according to the first reconstructed image and the two-dimensional image data set; generating a second reconstructed image from the three-dimensional image data set with a second spatial parameter; calculating a comparison similarity value according to the second reconstructed image and the two-dimensional image data set; comparing the comparison similarity value with the reference similarity value; and registering the two-dimensional image data set to the three-dimensional image data set if the comparison similarity value is not greater than the reference similarity value.

Abstract: This disclosure describes an interactive augmented reality system for improving surgeon's view and context awareness during laparoscopic and video assisted surgeries. Instead of purely relying on computer vision algorithms for image registration between pre-operation (or intra-operation) images / models and later intra-operation scope images, the system can implement an interactive mechanism where surgeons may provide supervised information in initial calibration phase of the augmented reality function, thus achieving high accuracy in image registration. Besides the initialization phase before operation starts, interaction between surgeon and the system can also happens during the surgery. Specifically, patient tissue might move or deform during surgery, caused by for example cutting. The augmented reality system can re-calibrate during surgery when image registration accuracy deteriorates, by seeking additional supervised labeling from surgeons. The augmented reality system can improve surgeon's view during surgery, by utilizing surgeon's guidance sporadically to achieve high image registration accuracy.

Abstract: A system and method for digital-representation-based flight path planning for object imaging is disclosed. An example embodiment is configured to: obtain a digital representation of an object; retrieve a dataset of image acquisition configuration parameters; extract a surface contour of the object from the digital representation of the object; generate a bounding polygon adjacent to the surface contour of the object, the bounding polygon being set-off from the surface contour of the object based on a configuration defined in the image acquisition configuration parameters; generate a configurable quantity of waypoints at configurable intervals along the bounding polygon; and generate an Image Acquisition Plan (IAP) from the waypoints, the IAP including, for each waypoint, a waypoint position, control instructions, and imaging instructions.

Abstract: A method includes accessing image data and depth data corresponding to image frames to be displayed on an extended reality (XR) display device, and determining sets of feature points corresponding to the image frames based on a multi-layer sampling of the image data and the depth data. The method further includes generating a set of sparse feature points based on an integration of the sets of feature points. The set of sparse feature points are determined based on relative changes in depth data with respect to the sets of feature points. The method further includes generating a set of sparse depth points based on the set of sparse feature points and the depth data and sending the set of sparse depth points to the external device for reconstruction of a dense depth map corresponding to the image frames utilizing the set of sparse depth points.
