摘  要：
随着计算机技术的发展和果园果树精细管理的现实需求,果树冠层的三维重构问题成为研究热点。本文采用激光传感器在不同高度对果树靶标冠层进行水平扫描测距;将从果树不同方位测得的探测点坐标进行坐标转换,得到同一坐标系下的果树冠层三维点云;采用插值法重构模型树冠层三维轮廓。试验结果表明重构的冠层轮廓较为准确地反映了果树的外形轮廓。本文研究为采用激光传感器测距技术进行果树冠层三维重构与体积测量提供了前期研究基础。

摘  要：
With the development of computer technology and the practical needs of the orchard management,so that three-dimensional reconstruction of tree canopy issue has become hot topic.In this paper,laser sensor was used to scan fruit tree canopy in a horizontal level plane at different heights;the three-dimensional point cloud of fruit tree canopy were getted through coordiante system transform that converted the measuring points coordinate getting from different measuring direction into the same coordinate system;the three dimensional of fruit tree canopy was constructed using interpolation method.The experiment result show that reconstruction of the canopy profile more accurately reflects the contour of the fruit tree.The study in this paper provides preliminary studies for three-dimensional reconstruction and volume measurements of fruit tree canopy using the laser ranging.
