Night Vision Image Processing Technology Research And Application

Computer vision is to use the computer instead of the human eye and brain of the objective world of visual perception and interpretation techniques, the development of modern disciplinary frontiers, the image processing method involves a lot of deep-seated problems of artificial intelligence. It is an important scientific field, is a technology-driven market. Have positive significance of Chinese teaching, research and economic.This paper mainly drains under night vision difficulty level observation, real-time problem is not strong. Under conditions designed to achieve a vision drains fluid handling real-time monitoring system. Through the hardware platform and software design has realized the monitoring level night vision under the condition of channel, is the important application of image processing technology in the concrete practice.This paper expounds on the night vision channel level real-time monitoring and control system working principle of each part, gives the specific implementation method, through analysis and comparison, completed the level night vision channel processing actual work monitoring and control system hardware selection, and demonstrates the composition of hardware system. After completing the hardware design based on the developed software system, the night vision image enhancement technique of histogram enhancement algorithm, direct contrast enhancement, mixing enhancement, fuzzy maximum entropy four methods to do the analysis comparison, through the key operator in the C++software platform invoke the HALCON to get gray level images, the threshold selection, character segmentation, region extraction, liquid level, eventually to achieve real-time monitoring content level night vision channel processing. Then use the programming procedure for real-time monitoring of the channel experiment. And the experimental results are analyzed and discussed.
