Registering Or Aligning Multiple Images To One Another Patents (Class 382/294)
  • Patent number: 11209548
    Abstract: Embodiments relate to methods for efficiently encoding sensor data captured by an autonomous vehicle and building a high definition map using the encoded sensor data. The sensor data can be LiDAR data which is expressed as multiple image representations. Image representations that include important LiDAR data undergo a lossless compression while image representations that include LiDAR data that is more error-tolerant undergo a lossy compression. Therefore, the compressed sensor data can be transmitted to an online system for building a high definition map. When building a high definition map, entities, such as road signs and road lines, are constructed such that when encoded and compressed, the high definition map consumes less storage space. The positions of entities are expressed in relation to a reference centerline in the high definition map. Therefore, each position of an entity can be expressed in fewer numerical digits in comparison to conventional methods.

    Abstract: A reduced noise image can be formed from a set of images. One of the images of the set can be selected to be a reference image and other images of the set are transformed such that they are better aligned with the reference image. A measure of the alignment of each image with the reference image is determined. At least some of the transformed images can then be combined using weights which depend on the alignment of the transformed image with the reference image to thereby form the reduced noise image. By weighting the images according to their alignment with the reference image the effects of misalignment between the images in the combined image are reduced. Furthermore, motion correction may be applied to the reduced noise image.

    Abstract: Systems and techniques are described for topography simulation of etching and/or deposition on a physical structure. The structural information can be represented using a three-dimensional (3D) voxel grid data structure. For each particle emitted by a Monte-Carlo particle emission model, a topographical modification caused by the particle can be determined by (1) calculating fluxes, (2) evaluating surface reactions, and (3) modifying the physical structure. The effect of the etching and/or deposition on a physical structure can be displayed by rendering the 3D voxel grid data structure.

  • Patent number: 10582137
    Abstract: Techniques are disclosed for adding time data to scan lines of an image frame. In some examples, an image sensor may perform a rolling shutter image capture to produce the scan lines. Data captured by another sensor may be associated with at least a portion of a scan line based at least in part on the time data added to the scan line in some examples. Furthermore, techniques are disclosed for synchronizing data capture by multiple sensors. For example, a rolling shutter image capture performed by an image sensor may be synchronized with a data capture performed by another sensor.

  • Patent number: 10521898
    Abstract: A method of structural masking for progressive health monitoring of a structural component includes receiving a current image of the structural component. A processor aligns the current image and a reference image of the structural component. The processor performs a structure estimation on the current image and the reference image to produce a current structure estimate image and a reference structure estimate image. The processor generates a structural mask from the reference structure estimate image. The processor masks the current structure estimate image with the structural mask to identify one or more health monitoring analysis regions including a potential defect or damaged area appearing in the masked current structure estimate image that does not appear in the reference structure estimate image.

    Abstract: An augmented reality (AR) display application generates mapped visualization content overlaid on a real world physical environment. The AR display application receives sensor feeds, location information, and orientation information from wearable devices within the environment. A tessellation surface is visually mapped to surfaces of the environment based on a depth-based point cloud. A texture is applied to the tessellation surface and the tessellation may be viewed overlaying the surfaces of the environment via a wearable device.

  • Patent number: 10482348
    Abstract: A system and method are provided for discriminating and tracking a coherently structured feature dynamically defined in evolving manner within a migratory medium. A data set is captured for a plurality of physical points defined within a multi-dimensional physical space, in terms of a plurality of scalar parameter values. At least one pre-selected target feature type is established, as is a scalar field predefined by at least one of the scalar parameters. A sparse set of key points is selectively generated a within the scalar field. Each key point is associated with one of the physical points and descriptive information adaptively determined therefor from the data content within a neighborhood of the physical point coinciding therewith. At least one predetermined feature-based operation is executed responsive to the descriptive information of the key points as a surrogate for execution generally on the data set.

  • Patent number: 10482622
    Abstract: Techniques for locating features of interest in warped images are described. For example, a destination image is generated from a source image based on warping a portion of the source image according to a backward map. Each of the two images is associated with a mesh having a tile-based geometry. The backward map maps points from the destination mesh to pixels in the source image. Triangles are formed from the tiles of the destination mesh. A forward map is generated based on the triangles and the backward map. The forward map maps points from the source mesh to pixels in the destination image. A point from the source mesh is identified that corresponds to a pixel of a feature of interest. The forward map is applied to this point to locate a pixel in the destination image. This pixel corresponds to the location of the feature in the destination image.
