# YOLOv5 for Crater/Boulder detection on Moon
|
20 |
-
|
21 |
-
A yolov5s and a yolov5l model was trained on a labelled dataset of marked craters/boulders on moon. This was trained for the 3rd problem statement *Automatic detection of craters & boulders from Orbiter High Resolution Camera(OHRC) images using AI/ML techniques* of *Bharatiya Antariksh Hackathon 2024*.

## How to use
|
24 |
-
|
25 |
-
- Install [yolov5](https://github.com/fcakyon/yolov5-pip):
|
26 |
-
|
27 |
-
```bash
|
28 |
-
pip install -U yolov5
|
29 |
-
```
|
30 |
-
|
31 |
-
- Load model and perform prediction:
|
32 |
-
|
33 |
-
```python
|
34 |
-
import yolov5
|
35 |
-
# from PIL import Image
|
36 |
-
|
37 |
-
# load model
|
38 |
-
model = yolov5.load('Gurveer05/moon-crater-boulder-detection-yolov5')
|
39 |
-
|
40 |
-
# set model parameters
|
41 |
-
model.conf = 0.25 # NMS confidence threshold
|
42 |
-
model.iou = 0.45 # NMS IoU threshold
|
43 |
-
model.agnostic = False # NMS class-agnostic
|
44 |
-
model.multi_label = False # NMS multiple labels per box
|
45 |
-
model.max_det = 1000 # maximum number of detections per image
|
46 |
-
|
47 |
-
# set image
|
48 |
-
img = 'path/to/image' # or use: img = Image.open('/path/to/image')
|
49 |
-
|
50 |
-
# perform inference
|
51 |
-
results = model(img) # add size=640 if needed
|
52 |
-
|
53 |
-
# inference with test time augmentation
|
54 |
-
results = model(img, augment=True)
|
55 |
-
|
56 |
-
# parse results
|
57 |
-
predictions = results.pred[0]
|
58 |
-
boxes = predictions[:, :4] # x1, y1, x2, y2
|
59 |
-
scores = predictions[:, 4]
|
60 |
-
categories = predictions[:, 5]
|
61 |
-
|
62 |
-
# show detection bounding boxes on image
|
63 |
-
results.show()
|
64 |
-
|
65 |
-
# save results into "results/" folder
|
66 |
-
results.save(save_dir='results/')
|
67 |
-
```
|
68 |
-
|
69 |
-
- Finetune the model on your custom dataset:
|
70 |
-
|
71 |
-
```bash
|
72 |
-
yolov5 train --data data.yaml --img 640 --batch 16 --weights Gurveer05/moon-crater-boulder-detection-yolov5 --epochs 10
|
73 |
-
```
