  • Patent number: 12008777
    Abstract: Disclosed herein are system and method embodiments to implement a validation of an SfM map. An embodiment operates by receiving a motion-generated map corresponding to a digital image, generating a first depth map, wherein the first depth map comprises depth information for one or more triangulated points located within the motion generated image. The embodiment further receives a light detection and ranging (lidar) generated point cloud including at least a portion of the one or more triangulated points, splats the lidar point cloud proximate to the portion of the one or more triangulated points and generates a second depth map for the portion and identifies an incorrect triangulated point, of the one or more triangulated points, based on comparing the first depth information to the second depth information. The incorrect triangulated points may be removed from the SfM map or marked with a low degree of confidence.

In the method, the display apparatus receives image data from the computer system and floating image data can be obtained therefrom. The floating image display apparatus displays a floating image via a display panel after a conversion process. After that, a user can manipulate directly on the floating image by gesture. A procedure running in the display apparatus can determine an interactive instruction according to variations of three-dimensional coordinates. When the interactive instruction is transmitted to the computer system, a new image data is formed in response to the interactive instruction. The display apparatus then displays a new floating image after receiving new data.

  • Patent number: 11145112
    Abstract: In a method of producing images of a stored three-dimensional model of the surroundings of a vehicle, the images are corrected for perspective. A camera picture is produced by a camera device of the vehicle, and is projected onto a projection surface in the surroundings model. A region relevant for driving is marked in the surroundings model and is projected onto a corresponding projection surface area of the projection surface. An image of the projection surface including the driving-relevant region projected onto the projection surface area is produced and output by a virtual camera that can move freely in the surroundings model.

  • Patent number: 11056040
    Abstract: In one embodiment, a computing system may determine that a target grayscale value for a frame falls within a predetermined grayscale range. The system may compute, based on the target grayscale value, barycentric weights for a predetermined barycentric coordinate system associated with vertices that each represents a subframe combination of zero or more subframe identifiers. The system select, using the barycentric weights and threshold values associated with respective dots in a dithering mask, a set of non-overlapping dot patterns from the dithering mask corresponding to the vertices of the barycentric coordinate system. The dots in the dithering mask may satisfy a spatial stacking constraint. The system may generate subframes to represent the frame based on the set of non-overlapping dot patterns and the subframe combination represented by each of the vertices.
