forest measurement

This paper introduces the measurement principles of three-dimensional laser scanning system and its process in forest measurement,and also elaborates how to gain forest measurement factors by this system.

该文介绍了三维激光扫描系统的测量原理、测树过程和测树因子的获取方法。

A novel error compensated prediction tree method used for lossless compression of multispectral imagery is proposed in this paper.

预测树方法是一种有效的无损多光谱图像压缩技术,将自适应线性预测方法与传统预测树方法相结合,提出了一种多光谱遥感图像的误差补偿预测树压缩方法。

Finally, the prediction tree is adopted to reduce the spectr.

再通过分类K L变换去除量化误差图像的谱间相关性 ,对K L变换后的特征图像采用预测树的方法进一步去除谱间结构相关性和空间相关性。

Prediction tree is a traditional and efficient method for lossless compression of hyperspectral image.

该文在传统预测树方法的基础上提出一种改进方法,该方法定义一个幅度拉伸因子来表达相邻波段的局部灰度变化,通过比较局部上下文梯度来估算该幅度因子,并用它对当前的预测值进行修正。

A new tree height measurement is presented,which is based on affine reconstructure.

论文提出了一种基于仿射重构的树高测量方法。

The conventional tree height measurement of extensive forest resources survey and monitoring uses the visual estimation or simple instrument measurement with low precision,failing to meet the requirement of precision forestry and digital forestry.

以往粗犷的森林资源调查监测中树高测量是通过目估或者简单的仪器和方法测量,精度比较差,满足不了“精准林业”和“数字林业”的要求,在森林资源日益减少的今天,对单木和林分实现精准无损伤测量显得尤为重要。
