  • Publication number: 20230030247
    Abstract: Invention relates to processing images of 3D scenes and to a method of asynchronous reprojection in a system of virtual or augmented reality, including (1) receiving color data and depth data of an initial 3D scene image for view A; (2) determining visual features of the initial 3D scene image and weights of the visual features, based on the color data, and determining depth of the visual features of the 3D scene image, based on the depth data; (3) generating a low polygonal grid for reprojection; (4) performing reprojection of the initial 3D scene image for view B different from view A by displacement of low polygonal grid nodes depending on the weights and depths of the image visual features. The method assures a high 3D scene frame rate, reduces image distortions at item borders during reprojection, and decreases data volume for 3D scene image transmitted via a communication channel.

  • Patent number: 10949980
    Abstract: Method and system for tracking a moving object may be used in virtual or augmented reality systems, in-site logistics systems, robotics systems and control systems of unmanned moving objects. The method of tracking includes a step of automatic adjusting a tracking area by detection and registration of unique combinations of elementary optical patterns, and a step of tracking change in position and/or orientation of a moving object by detection of unique combinations of elementary optical patterns and comparison thereof with the unique combinations of elementary optical patterns registered during the tracking area adjustment. The system for tracking a moving object comprises at least one tracker located on a moving object the tracker including an optical sensor, at least one marker strip including active markers forming elementary optical patterns in a picture obtained from the optical sensor, and a central processing unit.

  • Patent number: 10481679
    Abstract: Method for inside-out optical-inertial tracking of a movable object includes providing IR light by a plurality of markers; reading a picture from an optical sensor and detecting pixels satisfying predefined conditions by a first data processing device; detecting marker blobs, based on the pixels, and determining parameters of the blobs by the first data processing device; reading data from an inertial sensor; generating a consolidated data flow comprising the parameters of the marker blobs and the data of the inertial sensor by the first data processing device, and transmitting the data flow to a second communication device; determining a tracker positioning data in a coordinate system of a motion area of the object, based on the consolidated data flow, by a second data processing device; validating a model of a tracker motion path, based on tracker positioning data; extrapolating tracker positioning data onto an extrapolation horizon, based on the model.
