Embodiment Construction

[0025] The specific implementation process of the present invention is: when the infrared image of the imaging object is irradiated on the CMOS of the image acquisition module, the infrared image data collected by the CMOS is transmitted to the image processing module, and stored by the EDMA through the VP port FIFO of the TMS320DM642 DSP chip In the SDRAM chip, the TMS320DM642 DSP chip processes the image stored in the SDRAM chip. After the processing is completed, it is sent to the host computer through the EMAC interface through the image network transmission module, and then the host computer completes the display and storage of the image. At the same time, the video acquisition The module collects new video frames for the next round of processing. At the same time, the above processes are completed under the control of the software driver module.

Abstract

The invention discloses an image acquisition and processing system for uncooled infrared imaging. The image acquisition and processing system is composed of an image acquisition module, an image processing module, an image network transmission module and a software driving module. The image acquisition module uses an image acquisition chip as an infrared image sensor for acquiring real-time infrared images. The image processing module processes an acquired image signal by means of a video port provided on a TMS320DM642 DSP chip. The image network transmission module completes real-time network transmission of the images by using a PHY chip LXT971A and an EMAC controller integrated on the TMS320DM642 DSP chip. The image acquisition and processing system can complete image acquisition, processing and network initialization utilizing tasks, and has the advantages of high sensitivity, fast processing speed, high reliability, small size, low cost and the like.

Description

technical field [0001] The invention belongs to the specific application of infrared imaging technology, in particular to an image acquisition and processing system for uncooled infrared imaging. Background technique [0002] Infrared imagers were first developed for military purposes. After so many years of development, infrared thermal imagers have been widely used in the civilian market. In the military field, thermal imaging cameras are widely used in the sea, road, and air forces, such as target identification, precision guidance, night reconnaissance and surveillance, and so on. In the civilian field, with the reduction of production costs of infrared thermal imaging cameras, it plays an important role in medical treatment, electric power, industry, fire protection, etc., such as circuit board fault detection, circuit fault troubleshooting, etc., it can find some conventional methods Defects and errors that cannot be found can reduce costs, increase the pass rate of p...
