摘要
为解决作物叶面积的准确、高效测量问题,以大豆叶片为例,应用计算机视觉技术对大豆叶面积测量中校正图像的问题进行了研究,提出了基于投影模型校正法。实验验证结果表明,该方法利用较少的特征点对就能很好地校正叶片图像,解决了非线性校正问题,并且图像信息量损失小。
In order to calculating the lamina area accuratly, high efficiently, this pape sets soybean lamina for example and brings forward correction method of projection model which aimed at problems of how to correct image when measuring lamina area using the technology of computer vision. The experiment shows that this method which sovles the problem of non-linear correction can be used to con＇ect the lamina image with lesser feature points and lesser loss of information.
