    摘要: A method and system for generating a three dimensional map of an environment based on information acquired by radar. The system includes a ground-based vehicle, and a scanning radar, or combination of radars, that scans the surrounding environment in one or more vertical planes or along azimuth angles. The radar may be an electrical beam steering and scanning radar or a combination electrical beam scanning radar and mechanical scanning radar. Dynamic objects within the environment may also be identified and removed with the remaining static objects being used to generate a three dimensional map of the surrounding environment and to perform localization within the three dimensional map.

    摘要: A method for three-dimensional (3D) shape measurement includes generating fringe patterns using a dithering technique, projecting the fringe patterns onto an object using a projector, capturing the fringe patterns distorted by surface geometry of the object using an imaging device, and performing a fringe analysis to reconstruct a 3D shape of the object using the fringe patterns and the fringe patterns distorted by the surface geometry of the object. The step of generating the fringe patterns using the dithering technique may include binarizing sinuisoidal fringe patterns with the dithering technique. The step of generating the fringe patterns using the dithering technique may include applying an optimization algorithm.

    摘要: A system manages a buffer having a group of entries. The system receives information relating to a read request for a memory. The system determines whether an entry in the buffer contains valid information. If the entry is determined to contain valid information, the system transmits the information in the entry in an error message. The system may then store the received information in the entry. In another implementation, the system stores data in one of the entries of the buffer, removes an address corresponding to the one entry from an address list, and starts a timer associated with the one entry. The system also determines whether the timer has exceeded a predetermined value, transferring the data from the one entry when the timer has exceeded the predetermined value, and adds the address back to the address list.

    摘要: A laser engraving system (10) for engraving a unengraved workpiece (20) and an engraving method are provided. The laser engraving system includes an image processor (12), an engraving controller (13), a mechanical arm (14), and a laser (15). The image processor is configured for building a workpiece model (22) corresponding to an unengraved workpiece, partitioning the workpiece model into at least one section (224), generating at least one two-dimensional pattern (223). The engraving controller receives the signals of the relative position values and the at least one two-dimensional pattern. The mechanical arm is electronically coupled to the engraving controller and controlled by the engraving controller. The laser is electronically coupled to the engraving controller and controlled by the engraving controller in such a manner that the laser engraves an unegraved workpiece according to the at least one two-dimensional pattern.
