PhotoMesh v7.0. What s New in PhotoMesh v7.0

Transcription

1 PhotoMesh v7.0 PhotoMesh v7.0 fully automates the generation of high-resolution, textured, 3D mesh models from standard 2D photographs. Combining any number of photographs, in a wide range of formats and resolutions, PhotoMesh generates highly-detailed 3D models that can be viewed and queried using TerraExplorer or other 3D and GIS products. What s New in PhotoMesh v7.0 This new release introduces significant model quality improvements, aerotriangulation optimization for various photo types, enhanced workflow, improved functionalities and new PhotoMesh Unlimited licensing option. Highlighted in the 7.0 release is the all-new aerotriangulation mechanism for faster and more accurate support of various data sets, high quality model geometry and sharper texturing algorithm. General Improvements Quality improvements Performance improvements PhotoMesh packages - Basic/Plus/Unlimited/Enterprise User defined output area User defined output Coordinate System Coverage Map Optimization for very large projects Ground Control Points support Improved pyramid calculation and texturing New Remove Watermark workflow Redesigned settings and presets Aerotriangulation (AT) Improvements New AT algorithm Photo collection grouping constraints Expanded distortion parameters support Build Tile Improvements New Edge sharpening Improved thin wall reconstruction Improved fine features reconstruction Improved texturing

2 New input gamma support New Output Formats TerraExplorer for Web LAS DTM Improvements to existing formats Product Capabilities Elaborate tiling mechanism enables efficient handling of massive quantities of input imagery Use of network fusers dramatically accelerates processing time by enabling multiple computers to share the processing load Ground control points can be added/imported to improve model positioning accuracy Preview mode saves time and resources by enabling camera parameters and project settings to be validated on small project subset Color-coded coverage map makes it easy to evaluate camera coverage in each area of the project Flexible options for displaying aerotriangulation and build results Streamlined process of exporting models for geometry editing and re-importing them back to PhotoMesh Detailed build reports provide meaningful statistical and graphical information about the build process Multiple output formats are supported to ensure compatibility with a vast number of CAD and 3D solutions: 3DML Stream-optimized, high-resolution 3D Mesh Layer database for loading directly into TerraExplorer and streaming with TerraGate. DAE Textured Collada model per build tile. OBJ Textured OBJ model per build tile. OSGB Multi resolution textured model for use in OpenSceneGraph. CityBuilder CityBuilder-ready data that can be geospatially enabled by loading it into CityBuilder and merging it with classification information (such as building footprints). TerraExplorer for Web Multi resolution textured model for streaming to the HTML5 based TerraExplorer for Web application. Orthophoto A true-orthophoto that is created from the resulting textured mesh. DSM (Digital Surface Model) An elevation model that includes all elevation data, including buildings and reconstructed objects in the mesh. LAS Point cloud public file format for easy interchange of point cloud data.

3 PhotoMesh Installation To install PhotoMesh: Note: Note: On some operating systems, administrative privileges may be required. The standalone fuser installation is not included in the beta version of PhotoMesh. Install the full version of PhotoMesh on any machine that you want to use as a fuser 1. Place the PhotoMesh license file next to the PhotoMesh.msi file in the installation folder. 2. Double-click the PhotoMesh.msi file. The PhotoMesh Setup dialog box is displayed. PhotoMesh Setup 3. Click Next. The End-User License Agreement is displayed.

4 End-User License Agreement 4. Read the License Agreement and then select the I accept check box. 5. Click Next. The Setup Wizard installs PhotoMesh. 6. In the dialog box that is displayed when the installation process is complete, click Finish to exit the wizard.

5 Getting Started with PhotoMesh Step 1: Imagery Acquisition The first step in creating a 3D model is imagery acquisition. In this step all visible surfaces of the intended object or scene must be photographed from multiple viewpoints - using a frame based camera. The current version requires positioning and orientation information. Step 2: Photo Preparation After the object or scene has been photographed, the photographs should be organized into one or more collections. Each collection should include a homogeneous sets of photographs, all taken by the same physical camera with identical focal length and dimensions. Step 3: Creating a PhotoMesh Project PhotoMesh Manager creates a folder with the same name as the project. This is where all the project work files and output files will be located. The Project Settings dialog box is then used to view and edit basic project and build quality parameters, including terrain database, tile size, mesh complexity, texture quality and coordinate system. Step 4: Loading and Preparing Photos Photos are loaded into a project from an Excel file. Use the PhotoMeshSample.xlsx template in the installation folder. Step 5: Managing Fusers Fusers allow you to share the workload involved in processing the entire project between several computers on the same network. The Master computer controls the fusers on the client machines and assigns work to each of them when it becomes available. Connect PhotoMesh Manager to each of the fusers by doing the following: 1. In the PhotoMesh Options dialog box set the Working Folder to a shared folder that can be accessed by all of the fusers. 2. Open the PhotoMesh fuser on each machine and set the Working Folder to the location of the shared folder.

6 Step 6: Data Production After all photos are added to the project and all properties are set as required, you can begin the build process. As the Build process is progressing, the Build PhotoMesh Manager displays information about the steps being performed and the active fusers.
