植物叶面积无损测量预处理技术研究

Study on the Non-loss Measurement Pre-processing Technology of Plant Leaf Area

针对在计算机视觉技术对大豆叶面积的无损测量研究中,如何校正图像和去除植物叶片纹理特征等问题,提出了投影映射无损测量法。测量有效性不受叶片大小、形状差异和叶片图像中叶片周边白色背景的影响。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。

This paper advanced bilinear mapping non - loss measurement which aimed at problems of how to correct image and wipe off texture feature in study of non - loss measurement of soja - leaf area using the technology of computer vision. The validity of measurement has not been influenced by size, figure differentia and white background of leaf, the experiment shows that this method which sovles the problem of non - linear correction can be used to correct the lamina image with lesser feature points and lesser loss of information.
