video/ : test video folder

###### package.xml: discription file of package

###### CMakeLists.txt : cmake configration

##### CMakeLists.txt : cmae configration of the package

## installation

### Configure Cmake

Configure```CMakeLists.txt ```

```bash
gedit CMakeLists.txt
```

if you have OpenCV version more than one, uncommit and change line9,set the build path which one you want to use.

```cmake
#if u have OpenCV version more than one, set the build path which one u want to use
set(OpenCV_DIR "YOUR_PATH")
```

Ex:

```cmake
#if u have OpenCV version more than one, set the build path which one u want to use
set(OpenCV_DIR "/home/test/app/opencv-3.4.0/build/")
```
### Compile

make sure you are in the **ROS catkin workspace**.

```bash
$ catkin_make
```

## Run

Open a terminal and run the ros master

```bash
$ roscore
```

Open a new terminal. **Set this workspace on top!**

```bash
$ source devel/setup.sh	#(option, if workspace not on top)
$ rosrun detector detector_node
```

### Option: Listener

If you want to hear the message from the detctor_node. Run the listener node

massages：

[time stemp]

[detected object type]

[detected object confidence]

[detected object center positon]

Open a new terminal. **Set this workspace on top!**

```bash
$ rosrun detector listener
```

## Usage

### Video stream configurations

**Do not need to re-compile**

videl_file location is {ROS_Package Path}/video/{VIdeo Name}

```xml
<?xml version="1.0"?>
<opencv_storage>
                                            
<show_time>1</show_time>                    
<debug_mode>1</debug_mode>                  
<show_fps>0</show_fps>

<use_camera>1</use_camera>                  
<video_file>test.mp4</video_file>           
<camera_index>1</camera_index>              
<window_width>1280</window_width>           
<window_height>720</window_height>

</opencv_storage>
```

### Network configurations

**Do not need to re-compile**

network files location is {ROS_Package Path}/dnn/{File Name}

```xml
<?xml version="1.0"?>
<opencv_storage>

<net_type>1</net_type>              
<thresh>0.35</thresh>               
<nms_thresh>0.25</nms_thresh>

<Yolo_meanVal>1</Yolo_meanVal> 
<Yolo_scaleFactor>0.003921569</Yolo_scaleFactor>
<Yolo_config>/dnn_nets/yolo/yolov3-tiny.cfg</Yolo_config>
<Yolo_model>/dnn_nets/yolo/yolov3-tiny.weights</Yolo_model>
<coco_name>/dnn_nets/yolo/coco.names</coco_name>

<ssd_meanVal>127.5</ssd_meanVal> 
<ssd_scaleFactor>0.007843</ssd_scaleFactor>
<ssd_config>/dnn_nets/ssd/deploy.prototxt</ssd_config>
<ssd_model>/dnn_nets/ssd/mobilenet_iter_73000.caffemodel</ssd_model>
<ssd_name>/dnn_nets/ssd/ssd.names</ssd_name>
</opencv_storage>
