Q. How can I get my License?
A. If you received Discovery Kit from distributors, you can download your file following the instructions here. For additional licenses to be issued, please contact your business partner or license@seoulrobotics.org.
Q. My license has expired, how can I renew it?
A. Please contact your business partner or license@seoulrobotics.org to get a new license issued.
Q. I would like to use other types of LiDARs that do not appear in SENSR.
A. The lidars to be used are defined in your license file. To use other types of lidars, please contact your business partner.
Q. How to interpret the x and y velocity elements (SDK)?
A. The velocity is given through its x and y components. To calculate the object's velocity, use sqrt(xx + yy). To calculate the object's angle (direction), use atan2(y,x).
For example, if you have the x and y value below,
x: -10.330358505249023
y: -0.5107154250144958
-10 m/s and -0.5m/s are the x and y components of the velocity.
The velocity is 10.34 m/s, the angle is -3.09 rad.
Q. I have pcap file. Can I use it in SENSR?
A. SENSR only supports Rosbag files, if you need to use a PCAP file, it must be converted into rosbag first. As pcap files are manufacturer-specific, please get in touch with your lidar supplier to receive instructions.
Q. Which LiDARs do you support?
A. SENSR is sensor-agnostic. The list of integrated LiDARs can be found here
Q. How to get my IP address of Web Frontend?
A. You can find you ip address on the network by typing ifconfig
If the command does not work, please install net-tools and run ifconfig after:
sudo apt install net-tools
ifconfig
Q. I have set "Time Sync Configuration" and I have trouble in connection between lidar and algo node
A. Follow the instructions here.
Q. How do I know the intensity value of a given point?
A. Point intensity can be found in Rviz, the ROS 3D visualization tool.
For further details on using Rviz, please refer to how to know points intensity value
Further ressources on how to use Rviz can be found here
