基于图像的虚拟植物形态数据获取方法研究

Research on Getting Shape Data of Virtual Plant Based on Image Processing

在虚拟植物技术研究中,植物原始几何形态数据的获取是非常重要的,而传统的人工测量方法不但费时费力,且测量精度也不能满足后续建模的需要。为准确提取测量数据,从植物叶片入手,探讨了一种将数字图像处理与矢量化技术相结合的方法,首先将植物叶片栅格图像转换为矢量化的形态特征图像,并且以DXF矢量图形文件的格式输出,然后由AutoCAD读取并获得叶片几何形态数据的方法。实验证明方法测量精度较高、效率高、费用低,具有较强的实用性。

It is very important to get primitive geometric shape data of plants in researching virtual plant technology. The traditional manual method is time - consuming and inefficent, and measuring precision cannot meet the needs of subsequent modeling. In this paper, starting from the plant leaves, a method combining digital image processing with vector technology is discussed. Firstly, the plant leave raster image is converted into vector image and the file with DXF format is output. Finally, the results will be acquired by AutoCAD. Experment results show that it is more preeise, efficient and practical.
