红外热成像技术在作物胁迫检测方面的应用

摘要

Infrared thermography is a sort of machine vision technology which is used for imaging through receiving ther-mal radiation from molecules and atoms with random movement continuously.At present, the theoretical methods of infra-red thermography have been widely studied.This paper summarized the theory of infrared thermal imaging technology and introduced the application on agriculture briefly.The research actuality and progress application of thermal imaging tech-nologies were described on crop detection in detail including crop disease stress detection, water stress analysis, and freezing injury stress analysis.The further use of the technology on crop detection was prospected by summarizing the characteristics and the advantages of thermal imaging technology.%红外热成像技术是通过接收事物自身的分子及原子无规则运动产生的热辐射后，对事物进行成像的一种机器视觉技术。目前，国内外均在红外热成像方面做了较深入的理论方法研究。为此，简要地概括了红外热成像技术的原理，介绍了该技术在农业上的应用，并从作物病害胁迫检测、水分胁迫分析、冻害胁迫分析3个方面，具体说明了红外热成像技术在作物胁迫检测方面的研究现状。最后，通过总结热红外技术的特点及优势，对未来该技术在作物检测方面的研究方向进行了展望。
