Description: 数字图像处理的基本方法,可以实现图像的放大缩小，旋转，负片，函数变换-3D building reconstruction is a challenging problem addressed
by many researchers. Since airborne LIDAR data appeared as a
new data source in remote sensing and photogrammetry many attempts
were made to model buildings using LIDAR data. LIDAR
combined with aerial images was e.g., used for building reconstruction
by (Haala and Anders, 1997, Rotensteiner and Jansa,
2002).

Description: 随着LIDAR技术的出现，三维建筑物的提取也受到越来越多的重视。由于LIDAR数据分布的不连续性和不规律
性，直接从机载激光扫描测距数据中进行建筑物提取较为困难。本文提出了一种结合灰度影像的LIDAR数据三维建筑物提
取方法，分三个步骤：首先对灰度影像进行建筑物二维提取；然后将处理后影像和LIDAR数据粗匹配，初步确定LIDAR数
据中的三维建筑物区域；最后利用一组阈值操作进行三维建筑物的精确提取。实验结果表明该方法简单实用，适应性强。-With the emergence of LIDAR technology, three-dimensional building extraction has also been more and more attention. LIDAR data distribution as a result of non-continuity and regularity, directly from the location of airborne laser scanning data extraction more difficult to carry out the building. In this paper, a combination of gray-scale image of the LIDAR data extraction method of three-dimensional buildings, divided into three steps: First of all buildings on the two-dimensional gray-scale image extraction then processed LIDAR data images and rough match, LIDAR data to determine the initial three-dimensional buildings in the region the final threshold of use of a group of operations extract accurate three-dimensional structures. The experimental results show that the method is simple and practical, adaptable.

Description: 该程序包包含如下转换程序，可以完成激光雷达数据的多种格式的转换。
txt2las.exe
las2txt.exe
lasinfo.exe
las2shp.exe
shp2las.exe
las2tin.exe
las2dem.exe
las2iso.exe
lasboundary.exe
lasmerge.exe
las2las.exe
lasthin.exe
lasview.exe
laszip.exe-The program txt2las.exe converts LIDAR data from standard ASCII in various formattings to binary LAS format (version 1.2). The corresponding las2txt.exe turns binary LAS into human-readable and easy-to-parse textual representations. The tool lasinfo.exe prints out a quick overview of the contents of a LAS file, las2shp.exe turns binary LAS into ESRI s Shapefile format, shp2las.exe turns an ESRI s Shapefile into binary LAS, lasmerge.exe can merge several LAS files into one, las2las.exe allows extracting only last returns, only points within a bounding box, etc., lasthin.exe implements a simple point thinning algorithm, las2tin.exe triangulates the points of a LAS file into a TIN, las2dem.exe rasterizes them into a DEM, las2iso.exe extracts, optionally simplified, elevation contours, and lasboundary.exe computes a boundary polygon (i.e. a concave hull of the points). The little OpenGL viewer lasview.exe visualizes the contents of a LAS file and can also compute a TIN. It needs the GLUT32

Description: With the rapid development of remote sensing technology, three dimensional coordinates and intensity information of observation
target can be obtained directly from LIDAR system. It is one of the important issues in the study on LIDAR data processing that
how to extract the object from the point cloud data captured by laser scanning effectively without the help of spectral information as
well as other auxiliary data. In this paper, a method for the target extraction from the point cloud data in the absence of other
auxiliary data is proposed. Experiment results indicate that the mentioned method can extract interesting object points from LIDAR
point cloud data powerfully.
