# EasyPySpin
EasyPySpin is an unofficial wrapper for FLIR [Spinnaker SDK](https://www.flir.com/products/spinnaker-sdk/). This wrapper provides much the same way as the OpenCV VideoCapture class.
## Requirement
* PySpin
* Download Spinnaker SDK from [here](https://www.flir.com/support-center/iis/machine-vision/downloads/spinnaker-sdk-and-firmware-download/).
* OpenCV
## Installation
```sh
pip install EasyPySpin
```
After installation, connect the camera and try [examples/video.py](examples/video.py).
## Usage
### Capture image from camera
Here's an example to capture image from camera.
```python
import cv2
import EasyPySpin
cap = EasyPySpin.VideoCapture(0)
ret, frame = cap.read()
cv2.imwrite("frame.png", frame)
cap.release()
```
### Basic property settings
You can access properties using `cap.set(propId, value)` or `cap.get(propId)`. See also [supported propId](#Supported-VideoCaptureProperties).
```python
cap.set(cv2.CAP_PROP_EXPOSURE, 100000) # us
cap.set(cv2.CAP_PROP_GAIN, 10) # dB
width = cap.get(cv2.CAP_PROP_FRAME_WIDTH)
height = cap.get(cv2.CAP_PROP_FRAME_HEIGHT)
```
### Advanced property settings
`cap.set()` and `cap.get()` can only access basic properties. To access advanced properties, you can use QuickSpin API, which PySpin supports.
```python
cap.cam.AdcBitDepth.SetValue(PySpin.AdcBitDepth_Bit12)
cap.cam.PixelFormat.SetValue(PySpin.PixelFormat_Mono16)
```
The other way is to use `cap.set_pyspin_value()` or `cap.get_pyspin_value()`, which are supported by EasyPySpin. These methods check whether the variable is writeable or readable and check the type of the variable, etc., at the same time.
```python
cap.set_pyspin_value("AdcBitDepth", "Bit12")
cap.set_pyspin_value("PixelFormat", "Mono16")
cap.get_pyspin_value("GammaEnable")
cap.get_pyspin_value("DeviceModelName")
```
## Supported VideoCaptureProperties
Here is the list of supported VideoCaptureProperties.
In `set(propId, value)` and `get(propId)`, PySpin is used to set and get the camera's settings. The relationship between `propId` and PySpin settings is designed to be as close in meaning as possible. The table below shows the relationship between `propId` and PySpin settings in pseudo-code format.
| propId | type | set(propId, value) | value = get(propId) |
| ---- | ---- | ---- | ---- |
| cv2.CAP_PROP_FRAME_WIDTH | int | `Width` = value | value = `Width` |
| cv2.CAP_PROP_FRAME_HEIGHT | int | `Height` = value | value = `Height` |
| cv2.CAP_PROP_FPS | float | `AcquisitionFrameRateEnable` = `True` <br> `AcquisitionFrameRate` = value | value = `AcquisitionResultingFrameRate`|
| cv2.CAP_PROP_BRIGHTNESS | float | `AutoExposureEVCompensation` = value | value = `AutoExposureEVCompensation` |
| cv2.CAP_PROP_GAIN | float | if value != -1 <br> `GainAuto` = `Off` <br> `Gain` = value <br> else <br> `GainAuto` = `Continuous` | value = `Gain` |
| cv2.CAP_PROP_EXPOSURE | float | if value != -1 <br> `ExposureAuto` = `Off` <br> `ExposureTime` = value <br> else <br> `ExposureAuto` = `Continuous` | value = `ExposureTime` |
| cv2.CAP_PROP_GAMMA | float | `GammaEnable` = `True` <br> `Gamma` = value | value = `Gamma` |
| cv2.CAP_PROP_TEMPERATURE | float | | value = `DeviceTemperature` |
| cv2.CAP_PROP_TRIGGER | bool | if value == `True` <br> `TriggerMode` = `On` <br> else <br> `TriggerMode` = `Off` | if trigger_mode == `On` <br> value = `True` <br> elif trigger_mode == `Off` <br> value = `False` |
| cv2.CAP_PROP_TRIGGER_DELAY | float | `TriggerDelay` = value | value = `TriggerDelay` |
| cv2.CAP_PROP_BACKLIGHT | bool | if value == `True` <br> `DeviceIndicatorMode` = `Active` <br> else <br> `DeviceIndicatorMode` = `Inactive` | if device_indicator_mode == `Active` <br> value = `True` <br> elif device_indicator_mode == `Inactive` <br> value = `False` |
| cv2.CAP_PROP_AUTO_WB | bool | if value == `True` <br> `BalanceWhiteAuto` = `Continuous` <br> else <br> `BalanceWhiteAuto` = `Off` | if balance_white_auto == `Continuous` <br> value = `True` <br> elif balance_white_auto == `Off` <br> value = `False` |
## Command-Line Tool
EasyPySpin provides a command-line tool. Connect the camera and execute the following commands, as shown below, then you can view the captured images.
```sh
EasyPySpin [-h] [-i INDEX] [-e EXPOSURE] [-g GAIN] [-G GAMMA]
[-b BRIGHTNESS] [-f FPS] [-s SCALE]
```
