------------

## Running the app.
You can use **Code::Blocks**.
- Load the project file *.cbp in Code::Blocks.
- Select _Release_, not Debug.
- Compile and run with F9.
- You can alter command line arguments with _Project -> Set programs arguments..._

Or use **Cmake**.
```shell
$ cd *MyDir*
$ mkdir build
$ cd build
$ cmake ..
$ make -j4
```
------------

## Settings.
All important settings are stored in the `config.json` 
You can alter these to your liking. Please note the use of commas after each line, except the last one.

------------

## Debug.
You can use debug mode to find the optimal position for the borderline. 
To enable debug mode, start the app with the --debug flag set to true: 
```shell
./Traffic --debug=true
```
Alternatively, you can modify the command line argument in Code::Blocks by navigating to Project -> Set programs arguments... 
In debug mode, you’ll see the tail of each vehicle. When a vehicle’s tail crosses the imaginary borderline, it is added to the count. 
At this point, the bounding box is highlighted, which helps in identifying any missed vehicles.

------------

## MQTT messages.
You can receive MQTT messages locally at localhost:1883, the default setting. Messages are printed to the terminal. 
When connected to the internet, you can send MQTT messages to any broker you choose, such as broker.hivemq.com:1883. 
The app only sends messages when the MQTT_ON setting is set to true. The refresh rate, in seconds, is determined by MESSAGE_TIME. 
At midnight, all cumulative counts are reset. 
You can also follow the messages in a web browser. To do so, enter the port number after the IP address of your Raspberry Pi.

------------

## Preview.
If your Raspberry Pi is connected to the internet, you can view live footage in a browser. 
Simply combine the Raspberry Pi’s IP address with the MJPEG_PORT number specified in the settings to access the camera feed.

------------

## LCCV.
We use the Bullseye [LCCV camera](https://github.com/Qengineering/LCCV) code, which is a lightweight camera solution that leaves most computing resources available for deep learning tasks. If you prefer to use GStreamer, you can build the application with the CAMERA flag set to OFF:
```shell
$ cd *MyDir*
$ mkdir build
$ cd build
$ cmake -DCAMERA=OFF ..
$ make -j4
```

------------

## Final remark.
There is plenty of room for improvement. The most obvious upgrade would be adding more computing power. The network used is very lightweight. We’ve also published this application for the Rock 5C, an affordable ($60) device with an NPU. With this setup, you’ll immediately see the impact of using a more powerful DNN model.
