Abstract

The invention discloses an embedded infrared real-time signal processing system, which is mainly used for an infrared detection system. The system mainly comprises an embedded signal processing board card, wherein an FPGA (Field Programmable Gate Array) with an embedded Power PC (Personal Computer) microprocessor is used as a core controller and is externally connected with a large-capacity DDR2 SDRAM (Double Data Rate 2 Synchronous Dynamic Random Access Memory) and embedded peripheral equipment. An embedded real-time operating system Vx Works based software platform is established on the Power PC microprocessor; and embedded infrared real-time signal processing can be realized by rationally selecting software and hardware of an infrared signal processing algorithm. The system has the main advantages that: a design scheme of the embedded system is adopted; a hardware structure of the embedded Power PC microprocessor in the FPGA and the embedded real-time operating system Vx Works based software platform are used; the entire infrared signal processing system is integrated on one board card; and the entire system is provided with various external interfaces, has high real-time property and a small size and is convenient to carry.

Description

technical field [0001] The invention relates to an infrared signal processing system, in particular to an embedded infrared real-time signal processing system, which is mainly used for infrared real-time signal processing in an infrared detection system. Background technique [0002] The infrared detection system takes the infrared radiation of the target, converts it into an electrical signal output, and forms an infrared image to realize the detection of the target. An infrared detection system with excellent performance and meeting application requirements requires a real-time signal processing system with strong processing capability and high reliability as technical support. [0003] In the past infrared detection system, the typical structure of the signal processing system is as follows: the output image of the infrared detector is sent to the signal processing system, first enters the FPGA for preprocessing (non-uniformity correction, image enhancement), and the prep...
