# Reality Capture camera location to NERF conversion tool with per camera intrinsics
This tool is for use with https://github.com/NVlabs/instant-ngp and allows the use of Reality Capture camera locations.

## Installation
Copy rc2nerf.py file into instant-ngp\scripts folder

## Usage
Use Reality Capture to align cameras.

Export cameras alignment
```
Alignment -> Export -> Registration -> Internal/External camera parameters...
```

Save the CSV file exported from Reality Capture into the directory that contains your /images folder.

Open a shell (CMD, Powershell, Bash, etc.) and navigate to the directory with your CSV file and /images folder:

cd [PATH TO FOLDER]

Run the rc2nerf.py on this CSV file using the following command, replacing the text in brackets […] with the file names and paths on your machine:

## Commands
Example:
```
python "[PATH TO iNGP]\rc2nerf.py" --csv_in "[NAME_OF_CSV_FILE].csv" --imgfolder .\images
```
The quotes are only required if you have spaces in any of the folder or file names.

## Additional command examples
Scale the scene down by 0.01
```
python "[PATH TO iNGP]\rc2nerf.py" --csv_in "[NAME_OF_CSV_FILE].csv" --imgfolder .\images --scale 0.01
```

Display the cameras in 3d and set the camera size (for debugging only, requires installing `matplotlib` and `pytransform3d`)
```
python "[PATH TO iNGP]\rc2nerf.py" --csv_in "[NAME_OF_CSV_FILE].csv" --imgfolder .\images --plot --camera_size 1
```
