Abstract

The invention discloses a peripheral component interconnect (PCI) Express-based multiband infrared image real-time acquisition system and a PCI Express-based multiband infrared image real-time acquisition method. The system comprises an embedded host with a PCI Express x8 channel and a real-time image acquisition card, wherein the real-time image acquisition card comprises a field programmable gate array (FPGA) chip, a high-speed caching double data rate 2 synchronous dynamic random access memory (DDR2SDRAM), differential I/O interfaces connected with a multiband infrared detector and a PCI Express x8 card insertion part. The acquisition method for the system comprises that: the FPGA chip of the acquisition card simultaneously reads multiband infrared image data from the differential I/O interfaces, caches the read multiband infrared image data into the DDR2SDRAM, performs PCI Express bus bandwidth allocation after finishing acquiring an image frame, transmitting the data of the image frame to the host by a PCI Express x8 bus for real-time display and storage, and simultaneously caches the acquired data of the next image frame. The invention has the advantage of integrating a plurality of infrared band data discrete acquisition systems to form the multipath, high-speed, synchronous and real-time acquisition system which is miniature and highly portable.

Description

technical field [0001] The present invention relates to image acquisition technology, in particular to a real-time data acquisition and storage system and method between an infrared multi-band infrared detector and a computer based on a PCI Express bus, which is suitable for multi-band infrared image fusion systems and multi-band image synchronization Real-time display system. Background technique [0002] The infrared multi-band detection system is mainly composed of two parts: an infrared detector with multiple bands and a real-time acquisition and processing platform for infrared signals. With the development of infrared detection methods towards the direction of large area array, high frame rate, multi-band, and real-time detection, the amount of data that needs to be transmitted and processed by the image data acquisition system has also increased sharply, and the real-time acquisition of data and simultaneous multi-band data Collecting puts forward higher requirements...
