Preface: Entry-level process.
One. Software selection
Smart3D: The version generally chooses the latest version of the software, so that it can better connect to the ArcGIS Enterprise platform and improve the display efficiency.
Figure New Earth (LocalSpaceViewer): Download online to generate KML files for the specified range.
two. Get KML range data
The data used here is the data taken by P4R, open the Tuxin Earth software, select all the photos in the folder and drag them into the software, and draw the scope of the waist making area, and save it as kml data.
three. Production of 3D models
1. Import photos
Modify the coordinate system after importing the photo:
If there are multiple folders, you can import them into Group group:
When shooting, the distortion correction mode was not turned on. Now you need to fill in the camera-related parameters, which can be viewed through the photo notepad:
2. Empty three operations
Because P4R positioning is more accurate, just select the third item, so there is no need to execute rigid:
3. Rebuild the model
Blocking reduces the memory computing requirements, but not too small, so as not to affect the front-end display:
You can select the kml file we drew before, and only calculate the range:
Submit the reconstruction task.
4. Export the model
After the reconstruction is complete, set the export. First choose I3S:
Choose Scope. If it is a small-scale model, it is recommended to choose Tile-Wise; if it is a large-scale model, it is recommended to choose Cross-Tile. The production time is long, but the front-end display efficiency can be improved:
When exporting, if it matches ArcGIS online terrain service later, select EGM96 reference when rebuilding the model:
Finally, export the model, and load pro (here only part of the model within the scope of the extent is exported):
