  • Patent number: 10977764
    Abstract: A spherical image of a spatial environment is received and contains spherically arranged pixel values indexed by a time value. The spherical image is represented in a content creation coordinate system in reference to a spatial position in the spatial environment. The spatial position is indexed by the time value. A spatial relationship is determined between the content creation coordinate system and a spherical image reference coordinate system. Based at least in part on the spatial relationship and the spherically arranged pixel values, spherical distributions of image metadata are determined for the spherical image.

  • Patent number: 10977833
    Abstract: Data compression (and corresponding decompression) is used to compress blocks of data values involving processes including one or more of colour decorrelation, spatial decorrelation, entropy encoding and packing. The entropy encoding generates encoded data values which have variable sizes (in terms of the number of bits). The entropy encoding uses size indications for respective sets of data values to indicate the number of bits used for the encoded data values of the set. The size indications allow the encoded data values to be parsed quickly (e.g. in parallel).

  • Patent number: 10970592
    Abstract: An adhering substance detection apparatus includes calculating, first and second detecting, and generating units. The calculating unit calculates a variation in a feature value related to luminance in past and current captured images captured by an image capturing device, based on the luminance of pixels included in the captured images. The first detecting unit detects a first region in which the variation calculated by the calculating unit falls within a threshold range, and the feature value in the current captured image falls within a threshold range. The second detecting unit detects a second region in which an irregularity in a distribution of the luminance of the pixels included in the captured image satisfies a predetermined irregularity condition. The generating unit generates a sum region being a sum of the first and second regions, as an adhering substance region corresponding to an adhering substance adhering to the image capturing device.

  • Patent number: 10964068
    Abstract: Methods and devices for attribute coding for point clouds. In a top-down coding process a predicted geometry-weighted sum of attributes is determined for each occupied sub-volume of a volume based on a prediction operation that uses at least a geometry-weighted sum of attributes for the volume. The prediction operation involves up-sampling data from the preceding (parent) depth of the coding tree. The predicted geometry-weighted sums of attributes and corresponding original geometry-weighted sums of attributes are subtracted, in the attribute domain or in a transform domain to result in residual coefficients. The AC residual coefficients are coded in the bitstream. The transform used has a DC coefficient property, whereby the DC coefficient from transform of the geometry-weighted sums of attributes for the set of child sub-volumes is the geometry-weighted sum of attributes for the volume.

  • Patent number: 10957072
    Abstract: This invention applies dynamic weighting between a point-to-plane and point-to-edge metric on a per-edge basis in an acquired image using a vision system. This allows an applied ICP technique to be significantly more robust to a variety of object geometries and/or occlusions. A system and method herein provides an energy function that is minimized to generate candidate 3D poses for use in alignment of runtime 3D image data of an object with model 3D image data. Since normals are much more accurate than edges, the use of normal is desirable when possible. However, in some use cases, such as a plane, edges provide information in relative directions the normals do not. Hence the system and method defines a “normal information matrix”, which represents the directions in which sufficient information is present. Performing (e.g.) a principal component analysis (PCA) on this matrix provides a basis for the available information.

  • Patent number: 10935377
    Abstract: In a method for determining 3D coordinates of at least one predetermined point of an object, the object is arranged in a measurement region and a variable illumination source projects a variable pattern onto the object arranged in the measurement region. An image recording apparatus which is arranged in a previously known relationship with respect to the illumination source records an image of at least one section of the object illuminated by the variable illumination source. The at least one predetermined point is detected in the recorded image. The 3D coordinates of the at least one predetermined point are determined from the recorded image, taking into account the previously known relationship of the image recording apparatus with respect to the illumination source, if a check of the recorded image reveals that the at least one predetermined point is marked in the recorded image by a feature of the variable pattern.

  • Patent number: 10915787
    Abstract: In one embodiment, example systems and methods relate to a manner of generating training data for a classifier or a regression function using labeled synthetic images and a mapping that accounts for the differences between synthetic images and real images. The mapping may be a neural network that was trained using image pairs that each include an image of an object and a synthetic image that is generated from the image of the object by overlaying a rendering of the object into the image. The mapping may recognize the differences between features of the object in the real image and features of the rendering of the object in the synthetic image such as color, contrast, sensor noise, etc. Later, a set of labeled synthetic images is received, and the mapping is used to generate training data from the labeled synthetic images.
