摘要
冠层结构是描述作物植被—环境界面的重要议题,半球图像法以其方便、廉价、省时、省力获得了众多学者的青睐,但半球图像法的发展受到鱼眼镜头畸变和图像处理技术的限制。文章以模拟鱼眼镜头的模型照片为研究对象,应用Image-pro plus图像处理软件,得出从原始图像提取目标的方法步骤,易于理解,方便操作。对照相法研究林冠结构的图像处理方面有一定的指导作用。
Canopy structure is an important topic of any plant - - environment interface description, and digital hemispherical photography is wildly used because of facility, inexpensive, timesaving and laborsaving. The development of bemispherical photography is limited by two factors： one is the distortion of fish- eye lens, the other is the technology of image processing. The paper pro plus＂ software. It could be understood and operated easily. The paper had the instructional function in the image processing part of measuring canopy architectural parameters using off- the - shelf digital cameras with fish- eye lens.
