农田杂草识别技术的现状与展望

Status and Prospect for Recognition Technology of Farm Weeds

杂草是农业生产的大敌。其蔓延速度快,危害严重。目前采用的杂草识别技术主要有人工识别、计算机视觉技术识别、绿色识别、近红外光谱分析技术识别。近年来,随着光学仪器的不断发展和近红外技术的不断成熟,近红外技术的应用越来越广。因此基于近红外技术的杂草识别--绿色识别和近红外光谱分析技术识别将是今后农田杂草自动识别的主要措施。

Weeds is the most threat to agricultural production because they have quick spread and serious harm. At present, some major technologies, adopted to identify the farm weeds, include manual methods, computer vision technique, greenness recognition, assaying technique of near-infrared reflection spectroscopy. During the recent years, along with increasing development of optical instruments and near-infrared technique have been arriving at increasingly popular application of near-infrared technique. Therefore, greenness recognition and assaying technique of near-infrared reflection spectroscopy, based on near-infrared technique, will become major methods to auto-recognition of farm weeds in the future.
