笔者评：Gexcel Srl是点云数据获取与处理的软件解决方案提供商，旗下也有不同行业的典型应用系统集成解决方案，比如煤矿、古迹重建、车载机载测绘方案以及工业测量应用等。近期Gexcel Srl发布软件包PixR³，该软件可以自动从车载或机载获取的图像提取出点云数据。输出的点云格式与JRC 3D Reconstructor® and PointR³兼容。
In step with the path of the latest technologies 3D laser scanning and photogrammetry, Gexcel Srl has released the new PixR³ software package (R³ family) to automatically create 3D point clouds and meshes from images taken from terrestrial, mobile or UAV/airborne platforms. PixR³ can manage limitless images (according to the PC's memory) and extract 3D information thanks to a fully automatic process.
The 3D output (point clouds and meshes) can be easily geo-referenced and further processed into JRC 3D Reconstructor® and PointR³:PixR³ + JRC 3D Reconstructor® Mining is the perfect solution for volumes evaluation, profiles and contour lines extraction. Color images taken from UAVs and Drone platforms are initially managed by PixR³ to extract colored 3D point clouds. JRC 3D Reconstructor® Mining is later used to merge these data with point clouds coming from lidar or total station/GNSS field measurements. Volumes, cross sections, cut&fill, crests&toes, isolines, etc., can now be easily obtained thanks to the JRC 3D Reconstructor® Mining software package. A greater resolution of the model is assured by the capability of JRC 3D Reconstructor® to use full resolution of the color images. This feature again emphasizes the importance that JRC 3D Reconstructor® gives to the color information, the most powerful tool for detailed geotechnical and geological investigations. PixR³ + JRC 3D Reconstructor® Heritage/Architectonical can be successfully used in cultural heritage, construction and architectonical projects when the use of laser scanner is not suited or when it is necessary to joint point clouds data coming from images processing or Lidar acquisitions.
Gexcel Srl has a rich history spanning more than 10 years of proven fully featured lidar and imagery analysis software packages with the JRC 3D Reconstructor®, completely compatible with all terrestrial, mobile and airborne scanners from manufacturers such as Faro, Leica, MDL, Optech, Riegl, Stonex, Topcon, Trimble and Z+F. Gexcel Srl was established in 2007 from the academic know-how of the University of Brescia and the applied research achievements of the European Joint Research Centre (JRC), located in Ispra (Italy). Gexcel Srl is proud to support all major standard formats such as the ASTM E57 and LAS.
