This ROS package allow you to generate a radar like map using relative coordinate to the center, like as below.

## :rocket: Quick start

### 1. Installation from source

First you need to download all required source, like the [ros-image-transport-py](https://github.com/alexandrefch/ros-image-transport-py) package, that manage automaticly image stream.

Moreover you might need some python package like [OpenCV](https://github.com/opencv/opencv), you can install them by simply execute `pip install opencv-python` or better compile from source for GPU.

**Clone and Compile**

Clone thoose two packages inside the `src` directory of your catkin workspace.

```shell

git clone https://github.com/alexandrefch/radar-view.git

git clone https://github.com/alexandrefch/ros-image-transport-py.git

```

Now you can compile them using your catkin tool (`catkin_make`, `catkin_build` ...).

### 2. Custom launch file

Here you can find an example launch file where each parameters are described.

```xml

    

        

        

        

        

        

        

        

        

        

        

        

        

        

        

    

```

### :incoming_envelope: Messages

**RadarObj.msg**

The position `x` and `y` are relative to the center of the map, that mean that the center of the map is `(0;0)`, `label` and `color` param are optional you don't need to fill them to make a point appear on the map.

```py

float32 x                # x position [m]

float32 y                # y position [m]

string label             # obj label (optional)

std_msgs/ColorRGBA color # obj color (optional)

```

**RadarObjArray.msg**

```py

radar_view/RadarObj[] objects

```
