# OnlineDetectorSimulator
This little tool will simulate the online capabilities of the new detector. Therefore, a dataset has been created which offers the same structure as the data from the new detector. The software sends out the packages via UDP.
## Build instructions
1. Dependencies:
- Boost >= 1.58.0
- libconfig
- cmake
- A C++11 compiler like gcc
On debian-based systems install using the given commands:
`$ sudo apt-get install libboost-all-dev libconfig++-dev`
2. Clone the repository:
`$ git clone git@github.com:HZDR-FWDF/OnlineDetectorSimulator.git && cd OnlineDetectorSimulator`
3. Run cmake:
```bash
# Create build directory
$ mkdir build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ../src/.
```
4. Build the software
`$ make`
5. In the `bin` directory there will be two executables (`onlineDetectorSimulatorClient`, `onlineDetectorSimulatorServer`).
## Usage
The executable `onlineDetectorSimulatorClient` sends the UDP packages and `onlineDetectorSimulatorServer` receives them.
The usage of the program will be shown using `localhost`:
1. Copy the file `config.cfg` into the binary directory of your executables and make sure you have test data around.
2. Start `onlineDetectorSimulatorServer`:
```bash
$ ./onlineDetectorSimulatorServer <address>
```
In case of localhost it would be:
```bash
$ ./onlineDetectorSimulatorServer localhost
```
3. Start `onlineDetectorSimulatorClient`:
```bash
$ ./onlineDetectorSimulatorClient <packets_per_second> <address>
```
Take into account, that currently `packets_per_secon`d value is not equal to the images per second sent out. If you reduce the packet size in `config.cfg` you need to increase the `packets_per_second` value by the same factor to keep the same images per second rate.
```bash
$ ./onlineDetectorSimulatorClient 1000 localhost
```
The above command using the standard configuration in the repository sends approximately 1000 images per second via UDP.
After some time, quit the client program using `ctrl+c`. The server program will stop after a timeout of `10 s`
