High-speed Image Data Acquisition And Processing Technology

Faced with high-speed high-resolution spectroscopy and high-precision problem, high-speed spectrometer data acquisition and storage capacity are required. Data acquisition in the field of information technology is an important aspect, with the sensor technology, signal processing technology, computer technology, as the basis of modern detection techniques. In muti-spectral imaging single-spectral image pixels have a position inconsistent each other, it is asked for image data for image registration. Image Registration is one of the key technologies in the area of remote sensing image processing, target recognition, image reconstruction and robot vision.The design of the entire system with combination of hardware and software, structures a new high-speed data acquisition and memory software systems. The hardware parts are PCIE-1429 high-speed acquisition card and developed its own adapter card simulation, high-speed card is simulated the variety of data sources to achieve acquisition card data conversion hardware systems and the kinds of control tests. High-speed data acquisition application software is to set up virtual instrument software platform to interface the hardware part of the data storage and acquisition of command control. In the high-speed digital image storage disk array is used to achieve real-time storage, and hard disk array storage meets stability and integrity of the system. Image registration part in technical studies analyses and simulates technology-pixel registration. Registration for the sub-pixel technology are conducted in-depth study on the sub-pixel registration algorithm simulation study, a new sub-pixel registration algorithm and simulation is proposed for sub-pixel registration, and it studies technical reasons for the error analysis and simulation and trims error information in a new algorithm. The design of the entire system achieve fully meet the requirements of a variety of spectrometers, and achieve the requirements of a variety of data sources. System is stable and reliable, and the prospects will be applied widespread practical.
