摘要:
The present invention relates to a method and an arrangement for providing a 3D model of an environment. The method comprises the step of forming a mesh modelling the environment in three dimensions, said mesh comprising nodes interconnected by edges and having surfaces boarded by the edges, wherein each node is associated to a 3D coordinate in a geographical coordinate system, determining for a plurality of the nodes and/or surfaces and/or edges in the mesh a mesh uncertainty and associating the determined mesh uncertainty to the corresponding node and/or surface and/or edge.
摘要:
An annotation method for a three-dimensional model is disclosed. A first set of data representative of a three-dimensional model is stored in a computer memory. A second set of data representative of an annotation is also stored in the computer memory. The annotation is associated with a first spatial location on the three-dimensional model and a first display view. The three-dimensional model and a first graphical representation of the annotation is displayed according to the first display view, with the annotation being positioned as specified by the associated first spatial location. The displaying of the three-dimensional model is modified to a second display view different from the first display view. The annotation is removed from the display window, and an annotation indicator associated with the annotation is displayed. The annotation indicator is visible independent of any display view of the three-dimensional model.

Provided is an image management apparatus that enables, by a simple work, a label assignment to images such as in-vivo images captured by a capsule endoscope. The image management apparatus includes: an input unit 10 that receives input of a signal according to an operation from outside; a storage unit 14 that stores a plurality of types of labels to be assigned to the images; an image processing unit 13 that calculates feature quantity of each of the images; an image selecting unit 17 that selects an image according to the signal received by the input unit; a label extracting unit 18 that extracts, based on the feature quantity, one or more types of labels among the plurality of types of labels; a display control unit 19 that generates one or more icons corresponding to the one or more types of labels and causes the generated icons to be displayed on a screen; and a label assigning unit 20 that assigns, when an operation signal associating the image selected by the image selecting unit with an icon selected from the one or more icons is input, to the selected image, a label corresponding to the icon associated with the selected image.

A system (100) for displaying a multi-dimensional image and an annotation located therein, the system comprising receiving means (110) for receiving: the multi-dimensional image, the annotation, and representation data associated with the annotation, the representation data being indicative of a preferred representation of the multi-dimensional image and the annotation located therein; display means (130) for displaying an initial representation (300) of the multi-dimensional image and the annotation located therein; input means (120) for enabling a user to provide a visualization request when the initial representation shows at least a first part (310) of the annotation; and the display means (130) being arranged for, after receiving the visualization request, displaying the preferred representation (400) of the multi-dimensional image and the annotation located therein in accordance with the representation data, the preferred representation showing at least a second part (410) of the annotation, the second part being different from the first part.
摘要:
Objects (3, 4) of a three dimensional 3D virtual world that are represented on a two dimensional 2D image plane (6) are provided with labels (7, 8) which are generated in the 2D image plane (6) itself. The labels are in spatial registration with the object as represented on the 2D image plane. The generation of the labels in the 2D image plane avoids problems relating to perspective and aliasing which can occur when labels are provided in the virtual world itself and are rendered from the 3D virtual world.
摘要:
The present invention has the advantage over the prior art that it provides a labeling method suitable for a complete medical report. In an aspect the present invention provides intuitive visual manual labeling, easy navigation based on anatomy, feedback to improve segmentation interactively, and automatic labeling based on anatomical textbook knowledge and already provided manual labels.
摘要:
A system and method for annotation of patient image data. First, an image block having image data such as an image series is acquired. Then at least one geometric shape having associated annotation data is defined within the image block and at least one display plane is selected within the image block. The image data associated with the display plane is displayed. Finally, it is determined if the display plane intersect with the geometric shapes and for each display plane that intersects with a geometric shape, the annotation data associated with the geometric shapes being intersected by that display plane is displayed.
摘要:
A method and apparatus presents cases comprising images, wherein selection values are provided, which are assigned to the cases and which are determined from the images of the respective case, wherein the presentation of the cases depends on the selection values. The sorting values are determined depending on the selection values, wherein a case list is generated by sorting the cases according to the determined sorting values and wherein the cases are presented in accordance with the generated case list. The cases can be medical cases, wherein the images are medical images, in particular mammograms, and wherein the sorting value is a measure for the difficulty of evaluating the case and/or the probability of showing an illness.
