The Research Of Image Acquisition Technology Based On The Davinci Processor

As a result of domestic artificial target are low efficiency, poor security problems, this paper introduces the design of a DSP technology as the core of the automatic target-scoring system. This design uses TI company specializes in video/image processing direction of DM6437high speed DSP system as the core processor, image acquisition using Omni Vision company640*480OV7141pixel COMS image sensor. This design can collect real-time target image, target can be reported results in LCD screen display in real time, or images that are uploaded to the PC machine.The system of power supply module, serial output module, an image acquisition module and several other modules of the hardware circuit design, has extended the DDR2high-speed memory chips, greatly enhance the speed of data transmission. Because DM6437has the powerful data processing capability, at its inner embedded bullet identification algorithm, can be separated from the PC machine, independent operation, the results will be carried out in LCD real-time display. This design can collect real-time target image, the target results in LCD screen synchronous display image, can also be uploaded to PC machine, to achieve high accuracy, high efficiency automatic target reporting, can be very good to meet the requirements of modern small arms training, to avoid the traditional artificial target defect.
