# Computer Vision Bootstrap for Raspberry Pi
This is a default environment for computer vision applications written in Python. It wraps OpenCV and PiCamera for a quick start into into image analysis.
##### IMPORTANT - This package is under construction, feel free to contribuite, open issues or contact.
### Prerequisites
* PiCamera
* OpenCV
* Matplotlib
### Usage Example
```Python
from Camera import Camera
from Image import Image
from IO import IO
from IO import Servo
IO = IO()
Camera = Camera()
panServo = Servo(pin = 19)
panServo.rotate(dutyCycle = 7.5)
img = Image(Camera.takePhoto())
img.rotate(180)
img.save()
```
### Documentation
The documentation pattern is:
- Class
- __init__ | Class constructor
- Methods
Classes:
- Camera
- __init__() | This class is a singleton
- takePhoto() | Returns an OpenCV formatted image
- togglePreview() | Opens a window for camera image previewing
- Image
- __init__(image, path) | If a path is inputed as parameter it loads the image from the path. Image parameter is an OpenCV image array pattern. This class is a singleton
- show() | Plots a image for image previewing
- save() | Saves the photo in a folder named with the current date (31/12/2018) named with the hour (21:15:24) with the extension .png
- rotate(degrees) | Rotates an image
- IO
- __init__() | Setup the GPIO board, should be instanciated before other IO classes
- Servo
- __init__(pin) | Instanciates the servo on the pin passed as parameter
- rotate(dutyCycle) | Rotates the servo to the according dutyCycle
- Input
- __init__(pin, name, function) | If signal is received on pin it will trigger the function passed as parameter
- OutputClock
- __init__(pin, name, frequency) | Instanciates the OutputClock on the pin passed as parameter with a certain frequency. This sends a square wave to simulate external input signals.
- stop() | Stops the signal.
