Abstract

The invention discloses an injection type simulation system for an infrared digital image based on USB3.0 and a method thereof. The injection type simulation system is mainly used for supplying a simulation environment to a real-time signal processing platform for an infrared image. The injection type simulation system comprises a host computer with a USB3.0 interface and an injection type simulator for the infrared digital image, wherein the injection type simulator further comprises a USB3.0 controller chip, an FPGA (Field Programmable Gate Array), a DDR2SDRAM and a peripheral equipment interface. An injection type simulation method for the system comprises the following steps: 1) configuring the USB3.0 controller chip into a Slave FIFO mode and establishing a DMA (Direct Memory Access) transmission channel; 2) utilizing an image data receiving module established in the FPGA to read data from the Slave FIFO; 3) utilizing an image data caching module established in the FPGA to read and write DDR2SDRAM, so as to realize the caching of the data; 4) utilizing three different interface modes to send the data to a rear-stage platform. The injection type simulation system provided by the invention has the advantages that the latest USB3.0 protocol is adopted, the data transfer rate is high, the instantaneity is excellent and the portability is strong.

Description

Technical field: [0001] The invention relates to an infrared digital image injection simulation technology, specifically an infrared injection simulation system and method based on USB3.0 high-speed data transmission, which is mainly used to provide a simulation environment for an infrared image real-time signal processing platform. Background technique: [0002] Infrared photoelectric imaging detection equipment is usually composed of two parts: an infrared imaging sensor and a real-time image signal processing platform. The main task of the real-time image signal processing platform is to analyze and process the image signal sent by the infrared imaging sensor, and use the corresponding algorithm to detect a specific target from the complex background, and track or identify the target. The performance of infrared photoelectric imaging detection equipment depends to a large extent on the implementation of target detection and tracking algorithms, which needs repeated verifi...
