Product(s): ContextCapture Version(s): N\A Environment: Windows Area: N/A Subarea: N/A Problem You have an area (a city, or just a construction site) photographed and 3MX model completed. Some changes have been made (in a city a new building raised or the whole block rebuilt; or on the construction site some parts are built). How you can incorporate new photos and the changes on certain areas into an existing model, so that the whole model does not have to be regenerated? Solution Take photos of the new area of interest Ensure the new dataset includes enough photos to generate a good 3D model of the area that has changed: · Create a new block with the new photos · Do an aerotriangulation ensuring that it is correctly georeferenced · Create a new reconstruction with the same tiling (SRS, tile size, tiling origin) as the original reconstruction. · Produce the tiles in 3MX format with the same settings (same SRS, same SRS origin) · Replace the old tiles with the new ones. Note: Using this method there are likely to be texture discrepancies at the tile limit (due to the capturing being done at different times). Original Author: Felix James
