苗木分级是提高造林苗木成活率的一个重要手段,对植树造林、绿化环境有十分重要的意义。本文在对目前苗木自动分级文献理解和综合的基础上,首先通过对苗木分级技术和分级理论的研究,揭示了自动分级技术的发展背景和理论基础。进而对苗木形态参数的光电测量和计算机视觉测量等自动测量方法进行了分析和研究,阐述了现有的苗木自动分级系统所采用的分级理论和方法,并对其性能进行了概要的评述。最后,基于对苗木自动分级问题的理解,提出了苗木自动分级方法的一些展望。参31。
Seedling grading is to improve the survival rate of afforestation seedlings an important means of afforestation, afforestation environment is of great significance. Based on the comprehension and synthesis of the current automatic grading documentation of seedlings, this paper first reveals the development background and theoretical basis of the automatic grading technology through the research on seedling grading and grading theory. Then the automatic measurement methods such as photoelectric measurement and computer vision measurement of seedling morphological parameters are analyzed and studied. The existing classification theory and method of seedling automatic grading system are expounded and its performance is summarized. Finally, based on the understanding of seedling automatic grading, some prospects of seedling automatic grading are proposed. Participation 31.
