The Image Processor Evaluation And Test System Software Development

Image processing technology is the key technology of the national defense science and technology, and plays an important role in modern war. The image processor evaluation and test system is the important tool to test performance of image processor, providing guarantee for the development, debugging and improvement of image processor.This article is to develop the evaluation and test system software based on image processor test requirements, the main work is as follows:At first, this paper designs the evaluationand test system software solutions for image guidance system airborne and ground test, including airborne image recording software and image guidance algorithm testing software. Airborne image recording software realizes multi-channel high-speed LVDS image data acquisition and storage function in airborne test. Image guidance algorithm testing software implements function of simulation of the radar and infrared seeker in ground, sending high speed image data and instructions through an LVDS interface and 1553 B bus to the algorithms of image guidance, and receiving real-time algorithm results.Secondly,this paper designs the airborne records software. Through the control and access to the PCIE acquisition boards realize high-speed real-time image collection, and using double buffer to store the image. This paper uses DirectX image display acceleration to display the images. Complex task switching mechanism, system log and data analysis and playback are designed.This paper designs image information processing testing software, Can be used to test for target recognition and matching algorithm. It has the characteristics of high speed LVDS data sending and of binding the testing data automaticly.Then designs to achieve the high speed image real-time collection and storage based on the DSP processor, implementing the mass high-speed real-time data storage records independent of CPU system and solved the problem of the SATA hard disk capacity expansion, with high real-time and stability.At last, the paper has set up a completed the system test. The system works stable fully meet the indicators of the actual project requirements. The system has been utilized in airborne and ground test for many times for a certain institute.
