    摘要: A method, system, apparatus, article of manufacture, and computer readable storage medium provide the ability to reconstruct a pipe from point cloud data. Point cloud data is obtained. Primitive geometric shapes are detected in the point cloud data. A pipeline is determined by determining predecessor and successor primitive geometric shapes for each of the shapes. Diameters, coplanarity, and angles between the shapes are corrected. The shapes are connected and output.

    摘要: A method, apparatus, system, article of manufacture, and data structure provide the ability to extract a primitive quadric surface from point cloud data. Point cloud data is obtained in 3D space. The point cloud data is segmented to create a disjoined surface and a smooth surface segment based on spatial connectivity and surface smoothness. One or more shapes are extracted from the point cloud data using geometric fitting. The geometric fitting searches for one or more quadric surface parameters of a given type of model that provides a best agreement between selected points from the point cloud data and a resultant model.

    摘要: A method, apparatus, system, and article of manufacture provide object descriptors for objects in point cloud data for an urban environment by segmenting the point cloud data. Point cloud data for an urban environment is obtained using a ground-based laser scanner. Terrain points are filtered out from the point cloud data using ground filtering. The point cloud data is then segmented into two or more blocks. Objects that lie on neighboring adjacent blocks are combined. Object descriptors for the combined objects are then provided (e.g., to the user or a program used by the user).

    摘要: An approach is provided for building a scalable service platform by initiating transmission of encrypted data from a public network cache. An access control server platform determines a first authorization key for a user and a second authorization key for a resource, and then encrypts the resource with the second authorization key, and encrypts the second authorization key with the first authorization key. The access control server platform initiates distribution of the encrypted second authorization key with the encrypted resource over a network. The access control server platform further initiates caching the encrypted second authorization key with the encrypted resource that meets a predefined threshold value (e.g., a data size, an access frequency, a modification frequency, or an auditing requirement) in a cache in the network, and initiates transmission of the cached and encrypted second authorization key with the cached and encrypted resource from the cache to at least one authorized entity.

    摘要: An approach is provided for providing client-side caching in network communication. A client-side caching module receives a request, from a device, for a scripting file associated with web content, the scripting file supporting client-side caching at the device. The client-side caching module identifies that the request is received over a connection supporting connection reuse. The client-side caching module determines whether the request is a first-time request. If the request is a first time request, the client-side consistency module collects session configuration information for the web content from the device, specifies session variables in the scripting file based on the session configuration information, and initiates a subsequent request for the scripting file over the connection. If the request is a subsequent request, the client-side caching module marks the session variables in the scripting file as cacheable at the device, and causes, at least in part, transmission of the scripting file to the device.

    摘要: An approach is provided for coordinating service information (e.g., account registration identifiers) across multiple server nodes. A server receives a request to register an identifier for an account. The server determines whether it is a home site for the identifier and processes the request based, at least in part, on the determination.
