摘要

A system configured to process an input point cloud, which represents an object using unstructured data points, to generate a feature vector that has an ordered structure and a fixed length. The system may process the input point cloud using a basis point set to generate the feature vector. For example, for each basis point in the basis point set, the system may identify a closest data point in the point cloud data and store a distance value or other information associated with the closest data point in the feature vector. The system may process the feature vector using a trained model to generate output data, such as performing point cloud registration to generate mesh data, point cloud classification to generate classification data, and/or the like.

說明書

Each device (110/120) includes input/output device interfaces (702/802). A variety of components may be connected through the input/output device interfaces (702/802), as will be discussed further below. Additionally, each device (110/120) may include an address/data bus (724/824) for conveying data among components of the respective device. Each component within a device (110/120) may also be directly connected to other components in addition to (or instead of) being connected to other components across the bus (724/824).

Referring to FIG. 7, the device 110 may include input/output device interfaces 702 that connect to a variety of components such as a 3D scanner 112, image sensor (not illustrated), and/or other component(s) capable of generating image data and/or point cloud data. The device 110 may additionally include a display (not illustrated) for displaying content, although the disclosure is not limited thereto.
