Note 1: Since it is a photography machine, it deteriorates more than the original model.
The Shinjuku model which I made this time is also trying it personally in exploring the possibility of photography.
Used software
○”3DF Zephyr”
○Any movie crop software
iOS App『Perfect Video』
Once there is a trouble to transfer to the iPhone, it is high performance and easy to use.
Video editing software『AfterEffects』
Adobe users will do this better.
Procedure
1.GoogleEarth
2.Capture
When using the game bar for the first time, let’s check if the picture quality is high
Settings> Game> Settings can be changed from game DVR
I will record it so that all aspects can be seen evenly with Google Earth.
When the building is high, like peeping in from above.
We changed the height two weeks. I think that there is a true overhead view angle, but it can be roughly covered.
3.Movie cropping
Crop an unnecessary area from the captured video.
4.Read in 3DF Zephyr
Create a new project,
Click [Enter photo from video].
It is not drag and drop.
The Still Image Cropping setting screen from the movie will be displayed.
Specify a movie from [input file].
We left the other items as default this time.
When it is read [next].
転生は不要なのでそのまま[次へ]。
Since reincarnation is unnecessary, leave it as it is [next].
[Category] is set to “Aviation”.
First, preserve [preset] as “default”.
Go to the next screen and press the [Execute] button. If as a result there are too many camera position acquisition errors, change the above preset to “deep” and try again
(However, processing takes considerable time)
Once completed, such a model will be displayed.
The low density point group (temporary point group) and the position of the camera are displayed so as to surround it.
6.Generate high density point cloud
Because the current point cloud is provisional low density, we generate high density point clouds from the toolbar buttons.]
[Category] is set to “Aviation”.
[Preset] depends on accuracy to be asked. This time I wanted to produce a beautiful model as possible, so I made it “high definition”.
When you press Execute on the next screen, processing begins.
(It may take several hours depending on the number and accuracy of cameras)
7.Generate mesh
We will generate a mesh from here.
Click the mesh generation button on the tool bar.
[Category] is set to “Aviation”.
[Preset] I wanted to generate as beautiful model as possible this time, because the object is a building, I made it “high definition – sharp feature”.
(Although it is not as high density point group generation process, this processing also takes time)
8.Generate texture
When processing is finished, the mesh represented by such vertex color is displayed.
From the last step of this process, we will create a textured mesh from the toolbar buttons.
Settings according to your intended use.
If you want to set it to a number that can not be selected from the pulldown, it is possible to specify it by a numerical value by setting [Settings] on the upper right as a custom.
(This process takes less time to do so)
9.Exporting the model
GoogleEarthPhotogrammetry_16 When completed you can export textured model from this button.10.Import into DCC tool
Depending on the software, UV may collapse with fbx, so in that case write out with obj, load with another software, please try.
that’s all!
Here is the completed one
新宿作ってみた。
