摘要： Various methods and systems are provided for calibrating a camera-based feature detection system for an x-ray system having a support surface, and a gantry operably connected to the support surface and a light source disposed on the gantry, where the gantry defines a system referential. The x-ray system includes a camera spaced from the gantry and operably connected to a calibration system, the camera defining a camera referential within which the support surface and gantry are positioned. The calibration system registers the camera referential to the system referential by operating the light source to position an indication on the support surface and by obtaining a number of camera images of the indication on the support surface and corresponding indication location in the system referential.

摘要： A method, computer system, and a computer-readable medium for registering one or more structures to a desired orientation for planning and guidance for surgery is provided. The method includes in a preoperative stage, obtaining one or more 3D models of one or more structures from one or more CT images using an image processing segmentation technique or a manual segmentation technique; in the preoperative stage, registering the one or more structures to a template that is adapted to an alternating registration for a patient-specific shape and pose for a desired reduction and corresponding reduction transformations; in an intraoperative stage, mapping the one or more structures to one or more radiographs via a 3D-2D registration that iteratively optimizes a similarity metric between acquired and simulated radiographs; and in the intraoperative stage, providing an output that is representative of a radiograph or a 3D tomographic representation to provide guidance to a user.

摘要： The image processing apparatus acquires a first three-dimensional image, generates a second three-dimensional image by applying image processing to the first three-dimensional image having been acquired, and generates a two-dimensional projected image by applying projection processing to the second three-dimensional image having been generated. The image processing apparatus determines a parameter to be used for the image processing of the three-dimensional image on the basis of a parameter for the projection processing.

摘要： A non-Lambertian surface inspection system for line scan is proposed. Such a system includes: a surface inspection part including a frame module provided with a curved mounting hole formed on at least one of one surface and the other surface thereof and a photographing hole formed at an upper end thereof, and a plurality of first and second illumination modules installed in the mounting hole and output light in oblique lines toward an inspection object placed on a bottom surface thereof; a camera part positioned above the photographing hole, and configured to photograph the inspection object positioned on the bottom surface through the photographing hole and receive an entire reception image including first and second illumination images; and a controller configured to control operation of the camera part, selectively operate the first illumination module and the second illumination module, and extract the first illumination image and the second illumination image.

摘要： Systems and methods for generating a three-dimensional reconstruction from a two-dimensional image of an asset are described. In some aspects, at least one computer hardware processor is used to perform: receiving a two-dimensional input image of an asset; encoding, using a first statistical model, the input image into a latent vector; and generating, using a second statistical model, at least one depth image from the latent vector, wherein pixel values in the at least one depth image correspond to coordinates of a point cloud.

摘要： Provided are a method and apparatus for calculating three-dimensional coordinates using photographic images, and more particularly, a method and apparatus for calculating three-dimensional coordinates using photographic images in which a plurality of photographic images are analyzed to calculate the three-dimensional coordinate of a point commonly marked on the photographic images. By using the method and apparatus for calculating three-dimensional coordinates using photographic images captured by a camera, three-dimensional coordinates of arbitrary points marked on the photographic images can be easily calculated.

摘要： An image analyzing method of increasing analysis accuracy is applied to an image monitoring apparatus with a processor. The image analyzing method is executed by the first processor and includes receiving statistic data of an external electronic unit, transforming the statistic data into feedback data via specific algorithm, and generating a control parameter according to the feedback data. The control parameter is used to optimize image data output by the image monitoring apparatus.

摘要： This disclosure relates to an X-ray system for obtaining referencing information in the form of a coordinate transformation between a first volume and a second volume, with the volumes partially overlapping. In this case two partially overlapping subareas of an extended object having a continuous distribution of a physical size are discretely sampled with a measuring apparatus; the volumes are reconstructed and the overlapping volumes are iteratively changed, wherein a bandpass filter is applied to the overlapping volumes, where said bandpass filter changes the Fourier domain representation of the overlapping volumes. The filtered overlapping volumes, in which the artifacts, induced by the discrete sampling, are matched, are compared by means of a measure of similarity, which is iteratively maximized by means of mathematical optimization. The coordinate transformation with the maximum result for the measure of similarity is used as the optimal coordinate transformation for combining the two volumes in the correct position. One application is the combination of 3D X-ray volumes that have been reconstructed by means of a cone beam computed tomography scanner, preferably a 3D C-arm.
