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 (300) for allocating mobile station resources. The method can include receiving a message (120) over a wireless communications network (110) from an authorized user requesting reservation of communication resources on the mobile station (105), and automatically reserving the mobile station communication resources in accordance with the request. Receiving the message over the wireless communications network can include receiving the message on a slave mobile station. The message can be received from a master mobile station (115). In one arrangement the message can include a mobile station calendar entry. The calendar entry can be received in response to initiating a call on the mobile station. The call can be, for example, a selective dynamic group (SDG) call.
摘要:
A crack detection device for cylindrical parts includes centrifugal mechanism, which includes two stand columns (21), and a cross beam (22) is fixedly connected to the upper ends of the two stand column stand columns (21), two through holes (91) are formed in the cross beam (22), and a detection cavity (24) is formed between the cross beam (22) and the stand column (21). The traditional hand-held scanning equipment is not accurate in scanning range and has scanning holes. At the same time, it can only scan one side of the part, but still needs to turn the part manually. The lifting type automatic clamping device is adopted in the invention, which can scan the parts directly after fixing the parts.
摘要:
An apparatus and method for automatically generating radiation treatment planning parameters are disclosed. In accordance with the illustrative embodiment, a database is constructed that stores: (i) patient data and past treatment plans by expert human planners for these patients, and (ii) optimal treatment plans that are generated using multi-objective optimization and Pareto front search and that represent the best tradeoff opportunities of the patient case, and a predictive model (e.g., a neural network, a decision tree, a support vector machine [SVM], etc.) is then trained via a learning algorithm on a plurality of input/output mappings derived from the contents of the database. During training, the predictive model is trained to identify and infer patterns in the treatment plan data through a process of generalization. Once trained, the predictive model can then be used to automatically generate radiation treatment planning parameters for new patients.

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.
