Reference:

```
V. Usenko, N. Demmel, and D. Cremers, "The Double Sphere Camera Model", Proc. of the Int. Conference on 3D Vision (3DV), 2018.
```

## Requirements
Python >= 3.6 with numpy and opencv.

## Installation
Run the following command.
```bash
git clone https://github.com/matsuren/dscamera
cd dscamera
python setup.py install
```

## Camera calibration
Please use [Basalt](https://vision.in.tum.de/research/vslam/basalt) for fisheye camera calibration. The detail instruction is available [here](https://gitlab.com/VladyslavUsenko/basalt/blob/master/doc/Calibration.md).

## Example
Please check `example` folder for fisheye image rectifications.

Input fisheye image:
