PREFACE There are various publications on the 90th birthday of Gottfried Konecny.His involvement in the International Society for Photogrammetry and Remote Sensing(ISPRS)is particularly described by others.Here,his forward-oriented impulses in research and development at the former Institute for Photogrammetry and Engineering Survey of the(Technical)University of Hannover,today Institute for Photogrammetry and Geoinformation,Leibniz University Hannover,and some of his activities supporting developing and other countries by given short-term courses are highlighted.Gottfried Konecny was always one of the first in pushing new technologies.With the analytical plotter AP/C-3,he introduced analytical photogrammetry in Germany.Based on his experience with this not really operational version,he induced the company Zeiss to develop the first really operational analytical plotter Planicomp,which resulted in the end of analog photogrammetric devices and their limitations.At the invitation of Gilbert Hobrough,a mainly hardware-based image correlator was developed for the AP/C-3 in Hannover which anticipated many of today's applications.Gottfried Konecny initiated remote sensing in Germany.Based on his proposal with the Metric Camera Flight on Spacelab,the then highest resolution civil stereoscopic space images available were generated.Despite limited computer performance at his institute,a digital stereo plotter was developed,using hardware components from the cooperating Swedish company Context Vision,long before digital stereo workstations with increased and affordable computer capacity were possible.Also,in the area of GIS,he too,pushed development in collaboration with companies and administrations.Shortly before the end of his time as head of the institute,and more so after he became emeritus professor,he started a series of educational workshops,particularly in developing countries,but also other countries,to support the development of photogram-metry,remote sensing and GIS.He promoted the use of space imagery for mapping to improve the situation of poorly updated topographic maps.  相似文献

This special issue is dedicated to Prof.Gottfried Konecny(see Figure 1),the former president of the International Society for Photogrammetry and Remote Sensing(ISPRS)on the occasion of his 90th birthday,which he celebrated in good health and spirits in June 2020(see Figure 2).A visionary leader and missionary of global topographic mapping,a world scientist and a world citizen who restlessly built and continues to build sustainable bridges between different generations and different peoples of the globe and a true pioneer of photogrammetry and remote sensing,Konecny has shaped our field of research and development over the last 75 years in ways second to none.He also has a very special con-nection to China,which prompted the Editor-in-Chief of Geo-spatial Information Science to suggest this jour-nal as a very good place to publish this special issue.As the successor of Prof.Konecny at the Institute of Photogrammetry and GeoInformation of Leibniz University Hannover,it is with great honor,joy and thankfulness that Christian Heipke accepted the invi-tation to be guest editor of this special issue,together with Deren Li.  相似文献

ABSTRACT

During the last few years, artificial intelligence based on deep learning, and particularly based on convolutional neural networks, has acted as a game changer in just about all tasks related to photogrammetry and remote sensing. Results have shown partly significant improvements in many projects all across the photogrammetric processing chain from image orientation to surface reconstruction, scene classification as well as change detection, object extraction and object tracking and recognition in image sequences. This paper summarizes the foundations of deep learning for photogrammetry and remote sensing before illustrating, by way of example, different projects being carried out at the Institute of Photogrammetry and GeoInformation, Leibniz University Hannover, in this exciting and fast moving field of research and development.  相似文献

Preface I am pleased to contribute an article to GSIS to com-memorate the great achievements of Prof.Dr.Gottfried Konecny on the occasion of the celebration of his 90th birthday. I was lucky to work closely with Gottfried as an ISPRS Council member for the first time in 1984 in Rio de Janeiro,Brazil,when I was elected as Congress Director of the Kyoto ISPRS Congress to be held in 1988.Gottfried was elected as ISPRS President for 1984~1988.At the first Council meeting under the President Gottfried,he said to all Council members"as we are like a family,I request that we address each other by our first names".If he had not said this,I might have called him Professor Konecny,according to Japanese custom.  相似文献

A 90th birthday would be a milestone celebration for any person,but exceptionally rare if the person is still active after 75 years of working and serving the photogrammetric and remote sensing communities worldwide.This unprecedented career is the motivation to reflect on the technological developments of the past 75 years in the light of Gottfried Konecny's lifetime achievements.I started to get to know Gottfried not long before he officially retired from the Institute for Photogrammetry and Engineering Surveys in 1998.Furthermore,I was not even born when he,as a young and talented scholar supported by the Fulbright Scholarship from the US Government,arrived at the Ohio State University(OSU),which has been my professional home for three decades.In the second half of Gottfried's 75-year career,the technological changes have been phenomenal,and,furthermore,shown an accelerating trend in the past few years.It is absolutely remarkable how Gottfried has been able to keep up with these rapid changes and advancing technologies and exploits them for mapping and,in general,for all the users of the geospatial field at large.Additionally,his open-minded and kind personality has been always a major plus to his technical skills and experiences,and ultimately helped him assist many colleagues to advance their careers,and along the way developed and increased the use of geospatial data and systems in support of many countries worldwide.  相似文献

We discuss the evolution and state-of-the-art of the use of Unmanned Aerial Systems (UAS) in the field of Photogrammetry and Remote Sensing (PaRS). UAS, Remotely-Piloted Aerial Systems, Unmanned Aerial Vehicles or simply, drones are a hot topic comprising a diverse array of aspects including technology, privacy rights, safety and regulations, and even war and peace. Modern photogrammetry and remote sensing identified the potential of UAS-sourced imagery more than thirty years ago. In the last five years, these two sister disciplines have developed technology and methods that challenge the current aeronautical regulatory framework and their own traditional acquisition and processing methods. Navety and ingenuity have combined off-the-shelf, low-cost equipment with sophisticated computer vision, robotics and geomatic engineering. The results are cm-level resolution and accuracy products that can be generated even with cameras costing a few-hundred euros. In this review article, following a brief historic background and regulatory status analysis, we review the recent unmanned aircraft, sensing, navigation, orientation and general data processing developments for UAS photogrammetry and remote sensing with emphasis on the nano-micro-mini UAS segment.  相似文献

多级移动曲面拟合的自适应阈值点云滤波方法   总被引:2,自引:1,他引:1  
为了提高机载激光雷达点云滤波算法的精度、效率以及自适应性,提出了一种多级移动曲面拟合的自适应阈值点云滤波方法。首先,对点云数据进行预处理即剔除粗差,然后通过格网化分割建立格网索引,利用每个格网的邻域格网中的最低点建立曲面方程,计算真实高程与拟合高程的差值并设置自适应性阈值进行滤波,最后采用多级滤波策略,即逐级改变格网大小并自动设置邻域和阈值,直到滤波结果达到精度要求。使用国际摄影测量与遥感学会(ISPRS)提供的测试数据对算法进行验证,第1、2类误差和总误差平均值分别为7.33%、10.64%、6.34%。将该算法与ISPRS公布的8大经典滤波算法进行比较,结果表明该方法的适应性强,滤波结果具有较高的准确性。  相似文献

We presented a multiresolution hierarchical classification (MHC) algorithm for differentiating ground from non-ground LiDAR point cloud based on point residuals from the interpolated raster surface. MHC includes three levels of hierarchy, with the simultaneous increase of cell resolution and residual threshold from the low to the high level of the hierarchy. At each level, the surface is iteratively interpolated towards the ground using thin plate spline (TPS) until no ground points are classified, and the classified ground points are used to update the surface in the next iteration. 15 groups of benchmark dataset, provided by the International Society for Photogrammetry and Remote Sensing (ISPRS) commission, were used to compare the performance of MHC with those of the 17 other publicized filtering methods. Results indicated that MHC with the average total error and average Cohen’s kappa coefficient of 4.11% and 86.27% performs better than all other filtering methods.  相似文献
