Unity oblique photography development-aerial picture generation 3mx and OSGB model

1. First look at the 3mx and ogsb effects exported by cc
2. Use software cc software (the author uses the English version, you can Chineseize it according to your own situation): ContextCapture Center (version: 10.20.1.5.562) link: https://pan.baidu.com/s/12aTHhpt5cr3HkhaOp6zCGQ?pwd= c8q3 extraction code: c8q3 
3. Aerial picture material address: Link: https://pan.baidu.com/s/1JzUkIuKIkUmMJpVRhUwM1w?pwd=682a 
   Extraction code: 682a 
    
4. Operation steps and precautions for generating 3mx and osgb from aerial pictures:
   1. Start the ContextCapture Center Engine (this is the engine program for generating 3D models from images and must be started)
   2. Start the ContextCapture Center Master software
   3. Create a new project directory. Note: It is best not to have Chinese or special characters in directory and file names.
   4. To add aerial pictures, switch to Photos and click "Add entire directory..." to select the aerial picture file directory.
   5. Check whether the picture is normal, as shown in the picture below. The choice here is quick detection, which is fast and saves time.
   6. For spatial calculation, click the green "Submit Aerotriangulation" in the upper right corner and select "Process with ContextCapture Engine" from the drop-down menu.
   7. In the next window that pops up, just choose to use the default options. Keep clicking Next and wait for the space calculation to be completed. This calculation process takes a long time, so be patient and wait for it to complete.
   8. Reconstruct and export the 3D model, click "New Reconstruction" in the upper right corner, and select "3D reconstruction" to impact the model.
   9. Modify Tiling to Adaptve Tiling
   10. Click "Submit New Production" in the upper right corner and select the first submission in the drop-down menu
   11. The coordinate systems exported in 3mx format and osgb format are different. We export them in two types:
       1. Export in 3mx format,
          1. As shown in the figure below, select the 3mx format type and use the default settings above.
          2. Select EPSG:4544 for the coordinate system, otherwise the model may display abnormally.
          3. Other default options
       2. Export to OSGB format
          1. As shown in the figure below, select the OSGB format type,
          2. Select the WGS 84 coordinate system, as shown in the figure below
          3. Use the default items for others and wait for the export to complete. This part of the export will take several hours.
