Embodiment Construction

[0032] The specific implementation of the method will be further described in detail below according to the accompanying drawings. This system is aimed at infrared scanning imaging system. The input data rate of the detector is 15Mbyte / s, and the output is displayed in high-definition digital video (1080P). The terminal display is divided into two parts: the infrared panorama and the partial enlarged image. The position of the partial enlarged area is controlled by the joystick.

[0033] figure 1 Is the block diagram of the system-on-chip design. The system-on-chip design is mainly divided into two parts, the hardware processing part based on reconfigurable computing and the embedded system part. As mentioned above, the signal processing part of the system is based on reconfigurable computing, and realizes the reception, processing, buffering and display of optical fiber data through the logic resource resources inside the FPGA, and finally displays it on the terminal displa...

Abstract

The invention discloses an infrared image processing method based on reconfigurable computing. Signal processing is realized mainly through establishing a hardware logic in a programmable logic device. The realization method can be used in a photoelectric detection system needing high speed signal processing. A technical scheme adopted by the method comprises a hardware part and a software part. The hardware part mainly comprises a signal processing board with a large capacity programmable logic device as a core processor and with an optical input interface, a high definition video interface, a dynamic random access memory and the like. The software part mainly includes an infrared image processing hardware realization method based on the reconfigurable computing and the establishment of a system on a chip. The method has the following advantages: according to the infrared image processing method based on the reconfigurable computing, the signal processing ability of the system is raised evidently, development requirements of high frame rate and real-time signal processing of a photoelectric system are satisfied, and the system can be realized in a mode of the system on a chip, a framework is concise, and a volume is small.

Description

technical field [0001] The invention relates to an infrared image processing technology, in particular to an infrared image processing method based on reconfigurable calculation, which is mainly used for real-time image data processing in a photoelectric detection system. Background technique [0002] At present, image processing related to specific applications in optoelectronic systems is mainly implemented by processors, such as general-purpose processors (x86 or PowerPC) or dedicated digital signal processing chips (Da Vinci chips from Texas Instruments). The characteristic of the computing mode of the processor (see literature [1]) is that they all have their own instruction sets, and the calculation is completed by executing the relevant instructions in the instruction set, and the functions realized by the system can be changed by rewriting the software instructions without changing the underlying hardware environment. However, the operation speed of the processor is...
