Firstly, this paper introduced infrared detecting and tracking system (IR D&T System) and several commonly used scanning solutions in IR D&T System briefly. Secondly, it analyzed how 2D scanning mirror works and PID (Proportion, Integration and Differentiation) algorithm. Thirdly, it introduced commands format and controlling method of the 2D scanning mirror used in image-spectrum integrated instrument developed by our group. And then it designed controlling software of the 2D scanning mirror using its secondary development package (SDK) and VC++. The software communicates with 2D scanning mirror through serial port. The MSCOMM serial communication control is used in communication software design. The controlling software is integrated to software of image-spectrum integrated instrument successfully and experiment results verified the correctness of controlling algorithm and engineering usability of the software.
This paper put forward a design of Geomagic Plug-in based RE and RP System of 3D crafts and narrates the design method of the system software after giving some introduction to the design method of Geomagic plug-in. The system is an integration of RE and RP, with which we can easily make gifts with individuation and customization. Many experiments were carried out and the results showed that the design was reasonable and feasible and the research on the system was significant.
3D Printing is a widely used manufacturing method whose processing speed is very fast. This method is suitable for a variety of complex geometric structure in many application fields, and supports a variety of material types. At present, 3D printer is not only used in manufacturing, but also began to be used in education, architecture, design industries and so on. However, at home, there are less 3D printer manufacturers most of which are universities and research institutions, and price of 3D printer is relatively expensive. After analyzing how 3D printer works, this paper built 3D model of 3D printer and achieved printing simulation of STL model using two PCs basing on VC++ and ACIS/HOOPS. Two PCs communicate with each other through serial ports. One PC serves as host computer, on which controlling software runs, is responsible for loading the STL model, data processing, generating and sending printing commands and data to 3D printer. The other serves as slave computer, on which 3D printer simulation software runs, is responsible for receiving motion commands to control 3D printer to finish corresponding movements. Real-time rendering of 3D printer and human-computer interaction are achieved using rendering engine HOOPS. This method proposed in this paper adopted semi-physical virtual prototype technology, used real STL model to control virtual 3D printer to simulate 3D printing. It has no need for real 3D printer and is of important practical significance for debugging software of 3D printer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
