  • Patent number: 10839585
    Abstract: Described are methods and systems for real-time remote avatar creation and animation control. A sensor device captures images of non-rigid objects in a scene. A server coupled to the sensor device generates an initial 3D model for each of the non-rigid objects in the scene using the images. The server detects landmark points on the non-rigid objects using the initial 3D model. The server generates a control point animation map for the 3D model using the detected points. The server applies the animation map to the 3D model to generate a mapped 3D model. A viewer coupled to the server receives (i) the mapped 3D model and (ii) tracking information associated with the objects, including a model pose and deformation of the landmark points. The viewer modifies the mapped 3D model using the tracking information, and renders a video stream on the viewer using the modified 3D model.

  • Publication number: 20200357158
    Abstract: Described herein are methods and systems for remote visualization of three-dimensional (3D) animation. A sensor of a mobile device captures scans of non-rigid objects in a scene, each scan comprising a depth map and a color image. A server receives a first set of scans from the mobile device and reconstructs an initial model of the non-rigid objects using the first set of scans. The server receives a second set of scans. For each scan in the second set of one or more scans, the server determines an initial alignment between the depth map and the initial model. The server converts the depth map into a coordinate system of the initial model, and determines a displacement between the depth map and the initial model. The server deforms the initial model to the depth map using the displacement, and applies a texture to at least a portion of the deformed model.
