Laser marking has become one of the most important identification methods. Compared with the dots scanning marking method, vector scanning marking has a faster marking speed due to its less strokes and smooth trajectory. Based on the principle of the laser galvanometer scanning, an information processing method obtaining the vectors information, pre-marking until control the lasers trajectory is putting forward herein. Experiments proved that this information process method could be applied to character, barcode and any other graphs which could be described by vector information.

Gis Data

With the rapid development of information processing technology and continuously evolving technological hardware and software, the scale of spatial data has grown exponentially. This has necessitated that stricter requirements be placed on the way data is processed. The traditional single-machine centralized data processing method is gradually being replaced by the network-based cloud geographic information system (GIS) mode. However, the information processing method of the business system in the existing spatial information network environment is difficult to expand, which limits the application of the business system. This paper proposes an on-demand and extended model for the GIS data processing procedure that considers the three-way separation of algorithm development, business processes, and the operational interface, and can implement an on-demand expansion of business processes by process modeling the business and task scheduling the workflow engine. This can expand the scope of business systems and improve the efficiency of business system construction.

Reference Input

A robust optimal preview control method is presented in this paper for path tracking control problems to improve robustness and tracking precision of path tracking control systems. The known path information is used as reference input signals. Simulation results show that this method is valid not only for improving the performance of highly accurate trajectory control but also for improving system stabilization.
