Device and method for outputting signal of emulation infrared detector

Abstract

The present invention discloses a simulative infrared detector output signal device and method. The device includes a host machine PCI bus, an infrared picture data collected from the experiment in the outside field, and a simulative system driving program which are stored inside the host machine; a FPGA which plays roles of interface and controlling, and two SDRAM. The method includes: through an application program, infrared picture data is called from a database, and the driving program writes the infrared picture data into the memory of the host machine, then, the FPGA is informed to read out the infrared picture data in the memory of PC through PCI bus, and the infrared picture data is written into the SDRAM, at last, the infrared simulative picture data is read out from the SDRAM by the FPGA, and is sent to a back phase infrared real time signal processing platform according to the protocol. The present invention has the advantages that the real simulative data can be provided for the pre-stage research of the infrared signal real time processing platform; the infrared simulative data transmitted to the back phase infrared real time signal processing platform can not be interrupted in the frame; the relative data interface is provided according to the back phase infrared real time signal processing platform connected at the back terminal; and the target information can be real time superimposed when the infrared picture data is sent.

Description

technical field [0001] The invention relates to infrared alarm equipment, infrared search and track equipment, etc., and specifically refers to a device and a method for providing a simulated infrared detector output signal for an infrared real-time signal processing platform of the equipment. Background technique [0002] Infrared warning equipment and infrared search and track equipment are usually composed of two parts: an infrared detector and an infrared real-time signal processing platform. The main task of the infrared real-time signal processing platform is to process the image signal sent by the detector, detect the target with specific requirements from the complex background, and give the alarm information or track it at the same time. [0003] In the design and development process of infrared warning equipment and infrared search and track equipment, various simulation methods are widely used. By using various simulation methods, the design concept and design sc...

Problems solved by technology

[0004] There are two main types of simulation tests: 1. Semi-physical simulation, which is expensive and less flexible; 2. Digital image direct injection simulation. At present, most digital image injection simulation systems are based on low-speed buses. There is no large-capacity cache, and the data source is an analog image, so the output speed of the simulation data is slow, and there may be gaps between frames, and the simulation effect is not ideal
