The Laser Scanning Showing System And Research Of The Softwares

The application of the laser scanning technique is extensive. There are the vast development space and good applied foregrounds in the domestic. It not only can produce the economic performance but also will bring the social performance. This text summary the application and foregrounds of the laser scanning technique in the laser show and the laser process, and emphasize to research the laser scanning showing system.The thesis mainly did several works:1. It carried on the edge processing and the scanned track for the color or ash picture.It born to the calculate way.Then it carred out the compiled procedure.2. It put forward the solution of the USB port. The solution can carry out the calculator control. After pointing out the disadvantages of traditional interface used in the Galvanometer laser showing for data transfer, this paper introduces the advantages of USB interface in laser showing controller application, and analyzes its feasibility. For delivering the showing speed and lowering the cost, we choose the AN2131Q of the series of EZ- USB that is used for the USB port.3. It designed the EZ-USB2131Q port hardware. That hardware include the controller unit, the data and procedures saving unit, the D/A conversion unit, logic controlling unit and port unit. The system that includes the sketch edge born method and USB port controller can carry out the picture processing of the various document format and born to the scanning track of oneself.This system already carried out to use the USB communication port to control showing. The system software can collect various format pictures and born the scanning path. It is used conveniently.
