Convert2Yolo

Object Detection annotation Convert to Yolo Darknet Format

Support DataSet :

COCO
VOC
UDACITY Object Detection
KITTI 2D Object Detection

Pre-Requiredment

pip3 install -r requirements.txt

Required Parameters

each dataset requried some parameters

see example.py

--datasets
- like a COCO / VOC / UDACITY / KITTI
```
--datasets COCO
```
--img_path
- it directory path. not file path
```
--img_path ./example/kitti/images/
```

--label

it directory path. not file path

(some datasets give label *.json or *.csv . this case use file path)

--label ./example/kitti/labels/

OR

--label ./example/kitti/labels/label.json

or

--label ./example/kitti/labels/label.csv

--convert_output_path
- it directory path. not file path
```
--convert_output_path ./
```
--img_type
- like a *.png, *.jpg
```
--img_type ".jpg"
```
--manipast_path
- it need train yolo model in darknet framework
```
--manipast_path ./
```
--cla_list_file(*.names)
- it is *.names file contain class name. refer darknet *.name file
```
--cls_list_file voc.names
```

*.names file example

aeroplane
bicycle
bird
boat
bottle
bus
car
cat
chair
cow
diningtable
dog
horse
motorbike
person
pottedplant
sheep
sofa
train
tvmonitor

Example

1. example command

python3 example.py --datasets [COCO/VOC/KITTI/UDACITY] --img_path <image_path> --label <label path or annotation file> --convert_output_path <output path> --img_type [".jpg" / ".png"] --manipast_path <output manipast file path> --cls_list_file <*.names file path>

>>
ex) python3 example.py --datasets KITTI --img_path ./example/kitti/images/ --label ./example/kitti/labels/ --convert_output_path ./ --img_type ".jpg" --manipast_path ./ --cls_list_file names.txt

2. VOC datasets

description of dataset directory

suppose that VOC dataset location are ~/VOC and VOC folder contains VOCdevkit folder

here are structure for VOCdevkit

VOC datasets convert to YOLO format

now execute example code.

this example assign directory for saving YOLO label ~/YOLO/ and assign manipast_path is ./

make YOLO folder

$ mkdir ~/YOLO

VOC convert to YOLO

python3 example.py --datasets VOC --img_path ~/VOCdevkit/VOC2012/JPEGImages/ --label ~/VOCdevkit/VOC2012/Annotations/ --convert_output_path ~/YOLO/ --img_type ".jpg" --manipast_path ./ --cls_list_file ~/VOC/voc.names

TODO

Refactoring (Release v2.0.0)

Add strict Type Annotation in code
Separate role in class more strictly
Rewrite README.md for more helpful use first
Resolve the problem that strictly validation check when the trivial error
Supported Multiprocessing
Skip object class that don't want
