How to use ROS

Compile and run the node according to ROS Installation .

Tip

Before doing below you need open a terminal to launch ros node first

rostopic list lists all released nodes:

$ rostopic list
/mynteye/depth/image_raw
/mynteye/disparity/image_norm
/mynteye/disparity/image_raw
/mynteye/imu/data_raw
/mynteye/left/camera_info
/mynteye/left/image_raw
/mynteye/left/image_rect
/mynteye/points/data_raw
/mynteye/right/camera_info
/mynteye/right/image_raw
/mynteye/right/image_rect
/mynteye/temp/data_raw
...

rostopic hz <topic> checks the data:

$ rostopic hz /mynteye/imu/data_raw
subscribed to [/mynteye/imu/data_raw]
average rate: 505.953
  min: 0.000s max: 0.018s std dev: 0.00324s window: 478
average rate: 500.901
  min: 0.000s max: 0.018s std dev: 0.00327s window: 975
average rate: 500.375
  min: 0.000s max: 0.019s std dev: 0.00329s window: 1468
...

rostopic echo <topic> can print and release data. Please read rostopic for more information.

The ROS file is structured like follows:

<sdk>/wrappers/ros/
├─src/
│  └─mynt_eye_ros_wrapper/
│     ├─launch/
│     │  ├─display.launch
│     │  └─mynteye.launch
│     ├─msg/
│     ├─rviz/
│     ├─src/
│     │  ├─wrapper_node.cc
│     │  └─wrapper_nodelet.cc
│     ├─CMakeLists.txt
│     ├─nodelet_plugins.xml
│     └─package.xml
└─README.md

In mynteye.launch, you can configure the topics and frame_ids, decide which data to enable, and set the control options. Please set gravity to the local gravity acceleration.

# s2100/s210a modify frame/resolution
<arg name="request_index" default="$(arg index_s2_2)" />

# s1030 modify frame/imu hz
<!-- standard/frame_rate range: {10,15,20,25,30,35,40,45,50,55,60} -->
<arg name="standard/frame_rate" default="-1" />
<!-- <arg name="standard/frame_rate" default="25" /> -->

<!-- standard/imu_frequency range: {100,200,250,333,500} -->
<arg name="standard/imu_frequency" default="-1" />
<!-- <arg name="standard/imu_frequency" default="200" /> -->
...

# s2100 modify brightness
<!-- standard2/brightness range: [0,240] -->
<arg name="standard2/brightness" default="-1" />
<!-- <arg name="standard2/brightness" default="120" /> -->
...

# s210a modify brightness
<!-- standard210a/brightness range: [0,240] -->
<arg name="standard210a/brightness" default="-1" />
<!-- <arg name="standard210a/brightness" default="120" /> -->
...
<arg name="gravity" default="9.8" />

For printing debug info, replace Info in wrapper_node.cc to Debug :

ros::console::set_logger_level(
    ROSCONSOLE_DEFAULT_NAME, ros::console::levels::Info);
