果树虚拟修剪研究进展

摘要/Abstract

摘要： 树形结构对果树的产量和品质均有着重要的影响,而修剪是塑造优质高产树形最重要的管理措施之一。在真实果树上进行修剪试验或技术演示具有破坏性强、成本高、修剪效果难以快速呈现等缺点。果树虚拟修剪正是在此背景下随着虚拟现实技术快速进步而迅速发展起来的热点研究课题,其目标是在计算机构建的虚拟空间中可视化模拟果树的虚拟修剪操作及修剪对树形的影响,从而避免在真实果树上进行修剪所带来的时间和材料成本消耗。概述了果树虚拟修剪技术的研究进展,探讨了果树虚拟修剪的关键问题,包括三维重建技术、三维虚拟交互修剪技术及修剪后的形态发展模拟技术。分析总结现有技术方法优缺点,并结合相关领域的技术发展提出了展望。

Abstract: The tree structure has a strong influence on fruit yield and quality, and pruning is one of the most important management measures of tree shapes with high yield and good quality. Pruning test or technology demonstration in real fruit trees are irreversible defects, high cost, and difficult to fast rendering of pruning. Virtual pruning of fruit trees, which is in this context with rapid progress of virtual reality technology has developed rapidly and becomes the hot research topic. The aim is to create a space of virtual and simulate fruit tree pruning and the influence of pruning, so as to avoid the time and cost of material consumption in real fruit trees. The research progress of virtual pruning of fruit trees was summarized, and the key problems of fruit virtual pruning were reviewed, that is 3D Modeling technique, virtual interaction and growth simulation. The problems of the existing techniques were summarized, presenting prospect combined with advances in technology related fields.

Key words: virtual reality, fruit tree pruning, virtual interactive, growth simulation
