大多数农药和化肥的最佳施用是基于总体格罗夫条件。在本文中，我们提出了一个测量系统来估计树木作物的叶面。该系统基于地面激光扫描仪，估计树木的体积，然后使用简单快速的算法推断其叶面积，以实现真正的实时操作。用梨树进行的试验表明，体积与叶面积之间的关系可解释为线性关系，相关系数（R）为0.81，叶面积可由该体积估算，平均误差小于6%。
The optimization of most pesticide and fertilizer applications is based on overall grove conditions. In this paper, we propose a measurement system to estimate the foliage surface of a tree crop. The system is based on a ground laser scanner that estimates the volume of the trees and then extrapolates their leaf area using simple and fast algorithms to allow true real-time operation. Tests with pear trees demonstrated that the relation between the volume and the foliage can be interpreted as linear with a coefficient of correlation (R) of 0.81, and the foliage surface can be estimated from this volume with an average error less than 6%.
