Table of Contents

Via scan recording, it is possible to generate a 3D image of the surroundings from several 2D scans of the device using the path information of an encoder.

 

To create a point cloud with Sopas ET and LMS4000 you need following tools and Hardware:

  • Sopas ET installed and running on your computer
  • LMS4000
  • Power cable for LMS4000
  • Network cable to connect LMS4000 with your computer
  • Encoder with cable to LMS4000 (optional)

Setup
  • Power up your LMS4000 and connect the ethernet cable
  • Open Sopas ET and search for the LMS4000
  • Add LMS4000 to your Sopas project and open the device window
  • In Tab "Interfaces" set your Encoder mode (if no encoder available use "Fixed encoder ticks")
  • In Tab "Application"
    • Activate the filters you need or want to test
    • "Distance" and "Encoder ticks" needs to be activated in the output data format. You can activate "RSSI" optional to get the intensity information in the point cloud, too.
    • Define your Recording time, Movement type and Encoder resolution (note that the resolution is needed in mm per increment)
  • Start the 3D recording and after the record is finished you can save the point cloud with the button "Save 3D recording".

Additional Information
  • This function is not build to use in the productivity system. It should give you some information on how good the LMS4000 can measure on your target.
  • The scans are not added with the 600 Hz scan frequency. To add the scans to the recording, the UI frequency is used (20Hz). This could result in a bad accuracy in the movement direction which gets up tp 30x better when the telegram LMDscandata is used in the final application.
    • In the next screenshot you can see an example with a velocity of 1 meter per second.
      With the UI frequency the measured length of the package is only 100mm instead of 182,5 mm.
      With 600 Hz (output frequency you get via telegram "LMDscandata") you get the correct information regarding the edges of the package. This of course needs a constant speed or accurate encoder.
  • The axis of the point cloud is like in the following screenshot (x in scan direction; y the distance; z in movement direction)
