Research On Remote Image Acquisition System

The remote image acquisition system adopts a combination of server end and monitoring end, which can ensure that the system can shoot and transmit the real-time place photo, and realize the man machine interface under the circumstance of VC ++ 6.0.The monitoring end is divided into the upper part and the lower part. The upper part and the server end are made up of a PC machine. The main control chip in the lower part is TMS320F2812 produced by the TI Company. First, the server PC and monitor PC are interconnected, responsible for providing control pulse signals including scanning line signal and starting collecting signal for DALSA linear array camera at DSP2812. The upper part and DALSA linear array camera are connected through RJ45 Ethernet interface. After the connection is set up, the PC can process the images captured by DALSA linear array cameras. The processed images will be transmitted to the server end through the network. During the whole process, server control monitoring is responsible for image acquisition and transmission, this fuction is accomplished by multi-threading.A general introduction to the thesis structure is presented as follows:Chapter one expounds the previous and current situations as well as the development tendency. Then, the main content of this topic and research methods are introduced.Chapter two presents the design of the whole system, including the hardware and software realization method at the monitoring end and the server end.Chapter three introduces the specific method for the hardware in the lower part of monitoring end.Chapter four presents the specific method for the software in the lower part of monitoring end.Chapter five introduces the program of the upper end in the monitoring end and server based on VC++6.0, and the IP setting methods and the relevant data materials of the DALSA camera are especially elaborated. The system designed in this subject has been preliminary debugged under the laboratory conditions, the effect is very good and reach the expected goal.
