6 results about "Shape alignment" patented technology

Several examples describe techniques for aligning shapes using pose information for AI systems and applications. The systems and methods described here can use one or more pipelines configured to align shapes, such as three-dimensional shapes, using the shapes' poses. In some examples, training images to identify the poses, along with ground-truth poses associated with the training images, can be used to train a machine learning model. During and / or after training, the machine learning model can then be used to process additional images to identify poses of additional shapes. In some examples, a pose associated with a shape may include a gravity orientation and / or an azimuth orientation of the shape, as represented by an image.These poses can then be used to align the additional forms, such as in relation to a canonical pose.

Presentations showing eddy current (EC) test results can be generated and displayed. For example, amplitude or phase values ​​associated with an eddy current measurement signal can be presented graphically, such as by aligning an index of the amplitude or phase value with a shape representing the object under test, where the index corresponds to the location on or within the shape from which the eddy current measurement signal was obtained. In another example, the visual attributes of the displayed index of the amplitude or phase value can be assigned based on the defect class, such as using different colors corresponding to different defect classes, when the visual attributes are defined by regions within the impedance plane. The use of attributes to identify defects can be carried out either separately or in combination with alignment with the shape of the index.

The application provides an alignment mark, a preparation method thereof and a mask plate. The alignment mark is formed on a substrate and comprises a plurality of mark structures arranged in parallel with each other. The mark structure comprises a plurality of alignment blocks arranged discontinuously. By dividing the existing strip-shaped alignment mark into the discontinuous alignment blocks, the pattern density of the alignment mark region and the functional structure region can be adjusted more conveniently, the pattern density of the two regions is adapted to each other, the process compatibility of the alignment mark and the functional structure is improved, and the preparation of the unnecessary process level and the mask plate is reduced.

Embodiments of the present application provide a two-dimensional data and three-dimensional model combined display method, device, equipment and medium. The method comprises: obtaining model parameters of a three-dimensional model and data parameters of two-dimensional data; displaying the three-dimensional model on a first canvas; creating a second canvas on the upper layer of the first canvas, with the center point of the second canvas aligned with the center point of the three-dimensional model; converting the data parameters into parameters in the coordinate system of the second canvas; and displaying the two-dimensional data on the second canvas based on the converted data parameters. Since the position and shape of the two-dimensional data defined by the converted data parameters on the projection image corresponding to the currently displayed three-dimensional model are aligned with the position and shape of the two-dimensional data defined by the data parameters before conversion on the projection image corresponding to the previously displayed three-dimensional model, the automatic and accurate alignment of the two-dimensional data and the three-dimensional model can be achieved when displaying the two-dimensional data based on the converted parameters.

Methods and techniques for using an augmented reality device for determining an orientation of an instrument for inserting a medical device are provided. One such method includes simulating an insertion point and an orientation of a simulated surgical hardware installation on a diagnostic representation of a bone, and using an augmented reality based electronic device to align an instrument for inserting a surgical hardware installation at a desired orientation through an insertion point of the bone by displaying visual indicia indicating the insertion point and the orientation of the simulated surgical hardware installation. Disclosed herein is also a system and method having a concentric shape alignment system for medical device placement in the body, such as in a bone.

The present disclosure relates to systems, non-temporary computer-readable media, and methods for aligning curves to precise geometric shapes using a geometry alignment algorithm. The disclosed systems, for example, generate a set of discrete points along a curve represented in a digital image by scanning the curve extending between a first vertex and a second vertex represented in the digital image. The disclosed systems determine an arrangement or sequence for comparing the set of discrete points with a first geometry and a second geometry by comparing a centroid of the curve with a centroid of the first geometry and a centroid of the second geometry. The disclosed systems also determine, according to the arrangement or sequence,The sequence involves a first similarity of the curve to the first geometry and a second similarity of the curve to the second geometry. The disclosed systems generate curve segments that are aligned with either the first or the second geometry.
