Installation from source\n\nFirst 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.\nMoreover 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.\n\n**Clone and Compile**\n\n\u003cfont size=2\u003e\n\nClone thoose two packages inside the `src` directory of your catkin workspace.\n\n```shell\ngit clone https://github.com/alexandrefch/radar-view.git\ngit clone https://github.com/alexandrefch/ros-image-transport-py.git\n```\n\n\u003c/font\u003e\n\nNow you can compile them using your catkin tool (`catkin_make`, `catkin_build` ...).\n\n### 2. Custom launch file\n\n\u003cfont size=2\u003e\n\nHere you can find an example launch file where each parameters are described.\n\n```xml\n\u003c?xml version=\"1.0\"?\u003e\n\u003claunch\u003e\n    \u003cnode pkg=\"radar_view\" type=\"RadarView.py\" name=\"radar_view\"\u003e\n        \u003c!-- [optional] Update frequency (default=10hz) --\u003e\n        \u003cparam name=\"frequency\" type=\"int\" value=\"10\"/\u003e\n        \u003c!-- Input topic name --\u003e\n        \u003cparam name=\"input_topic\" type=\"str\" value=\"/path_to_your_input_topic\"/\u003e\n        \u003c!-- Output topic name (type is sensor_msgs.msg.Image) --\u003e\n        \u003cparam name=\"output_topic\" type=\"str\" value=\"/path_to_your_output_topic\"/\u003e\n        \u003c!-- [optional] Map resolution in pixel (default=1024px) --\u003e\n        \u003cparam name=\"map_resolution\" type=\"int\" value=\"1024\"/\u003e\n        \u003c!-- [optional] Map range in meter (default=80.0m) --\u003e\n        \u003cparam name=\"map_range\" type=\"double\" value=\"80.0\"/\u003e\n        \u003c!-- [optional] Map graduation distance (default=10.0m) --\u003e\n        \u003cparam name=\"map_graduation\" type=\"double\" value=\"10.0\"/\u003e\n        \u003c!-- [optional] Use clockwise angle (default=false) --\u003e\n        \u003cparam name=\"clockwise\" type=\"bool\" value=\"true\"/\u003e\n    \u003c/node\u003e\n\u003c/launch\u003e\n```\n\n\u003c/font\u003e\n\n### :incoming_envelope: Messages\n\n**RadarObj.msg**\n\nThe 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.\n\n\u003cfont size=2\u003e\n\n```py\nfloat32 x                # x position [m]\nfloat32 y                # y position [m]\nstring label             # obj label (optional)\nstd_msgs/ColorRGBA color # obj color (optional)\n```\n\n\u003c/font\u003e\n\n**RadarObjArray.msg**\n\n\u003cfont size=2\u003e\n\n```py\nradar_view/RadarObj[] objects\n```\n\n\u003c/font\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falexandrefch%2Fros-radar-view","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Falexandrefch%2Fros-radar-view","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falexandrefch%2Fros-radar-view/lists"}
