The results showed that:(1) some governing points, which were measured by submeter precision GPS, were utilized to correct the 1 m precision remote sensing image and it could satisfy the desired precision of geometrical correction, therefore, this method could be used as geometrical correction in the region where was short of the big scale relief map;(2) the density of the original data was the main factor to affect precision of the volume, and the precision of the calculated volume of earthwork could be improved to more than 90% when using the test points and feature points; the sparser the data density were, more significant could be improved; On the base that elevation of test points were measured by the submeter precision GPS, the error of the volume, which was produced by vectoring relief map to obtain DEM, could be calculated, and the calculation precision of the earthwork could be improved markedly.

结果表明:利用平面精度达亚米级的GPS测量控制点坐标对1米分辨率的遥感卫星影像进行几何校正,能够满足其几何校正的精度要求,可以解决缺乏大比例尺地形图地区的高分辨率遥感卫星影像的几何校正问题;通过对模型数据的分析,数据密度是影响体积精度的主要因素,利用检测点高程和特征点可以提高土方量计算的精度,使土方量计算的精度达到90%以上,数据密度越稀疏,精度提高越显著;采用高程精度达厘米级的RTK(Real Time Kinematic实时动态差分)测量检测点的高程,对用地形图扫描矢量化形成的DEM模型进行检测求出误差体积,可以大大提高土方量的计算精度。

This paper proposes a new EEG lossless compression technology based on improved DM Coding and Adaptive 2-Value Arithmetic Coding:First, DM Coding is used to the original data, and them through an appropriate transform of data format, most of the "redundant" bits in every byte are removed, also its Entropy of bits is reduced.

引言 多年来,嫡编码作为数据无损压缩的重要手段在生物医学信号的处理中一直得到广泛地应用,同时对于脑电信号的处理来说更是如此:由于神经疾病的诊断需要容量庞大的分析数据以及脑电波自身内涵的复杂性使得无损压缩对于脑电数据的处理而言异常重要;在另一方面,霍夫曼编码(Huffman Cod-ing)。
