## 2. Extrinsic Parameter Calibration
|
||
|
|
Prepare your images as following:
|
||
|
|
```bash
|
||
|
|
./data/examples/calibration
|
||
|
|
├── extri_images
|
||
|
|
│ ├── 1.jpg
|
||
|
|
│ ├── 2.jpg
|
||
|
|
│ ├── 3.jpg
|
||
|
|
│ ├── 4.jpg
|
||
|
|
│ ├── 5.jpg
|
||
|
|
│ ├── 6.jpg
|
||
|
|
│ ├── 7.jpg
|
||
|
|
│ └── 8.jpg
|
||
|
|
└── intri.yml
|
||
|
|
```
|
||
|
|
The basename of the images must be same as the name of cameras in `intri.yml`.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
python3 scripts/calibration/calib_extri.py -i ./data/examples/calibration/extri_images -o ./data/examples/calibration --debug
|
||
|
|
```
|
||
|
|
To specify your chessboard, add the option `--pattern`, `--grid`
|
||
|
|
```bash
|
||
|
|
python3 scripts/calibration/calib_extri.py -i ./data/examples/calibration/extri_images -o ./data/examples/calibration --debug --pattern 9,6 --grid 0.1
|
||
|
|
```
|
||
|
