# stardust
Detect constellation from starry pictures and draw constellation line.  
2017/10~

## Example
stardust can detect constellation from astronomical pictures(Photo by Rikuo Uchiki).

|input|output|
|---|---|
|<img src="./example_input.JPG" width=400px>|<img src="./example_output.JPG" width=400px>| 
 
stardust can also detect constellation from pictures that include ground(Photo by takasa5).

|input|output|
|---|---|
|<img src="./example_input2.JPG" width=400px>|<img src="./example_output2.JPG" width=400px>|

## Background and Goal
When my first time of watching starry sky I tried to find some constellations, but I could find few prominent constellations.  
Typically, without prior knowledge about position of constellations, finding them is so difficult.  
Now, with a smartphone app, we can know constellation's approximate position (thanks to GPS & gyro sensor).  
So, my goal is to identify constellation and it's position **accurately** from image.  
Combining this system and GPS and gyro (and high sensitively camera), we can watch starry sky with constellation information.

## Requirements
```
opencv-python==3.4.0
numpy==1.14.0
scipy==1.1.0
```

## Usage
```
$ git clone https://github.com/takasa5/stardust
$ cd stardust
```
```python
from stardust import Stardust
import Constellation as cs

# Initialize Stardust with image path (or image array)
sd = Stardust("./input.jpg")
# Select constellation from Constellation-class
cstl = cs.Sagittarius()
# Draw constellation line if detected
sd.draw_line(cstl)
# Get image 
ret = sd.get_image()
# cv2.imshow() or cv2.imwrite()
```

Moreover, you can use stardust easily by LINE bot.
