Image processing system for robot workspaces

This is what the plasmo 3D observer can do

  • Provides 3D laser measurement for robot workspaces of several cubic meters
  • Measures highly precisely those parts that the robot grips or singles out and determines the gripping point
  • Takes component tolerances into account
  • Based on laser triangulation and is adjusted extremely accurately or calibrated precisely to a camera pixel
  • Is particularly temperature stable due to carbon fiber elements
  • Due to a very high scanning rate achieves shortest possible cycle times and therefore greatest possible integration into the automation process
  • Enables the positioning of the camera several meters above the measuring area and thus avoids possible collisions with the robot
  • Offers high flexibility as regards the interface solutions to CAD data
  • Has a freely scalable system, which enables an optimal adaptation of the measuring space and working distance to the customer system
  • Achieves - depending on the working range - absolute accuracies of less than 0.5 mm

How the plasmo 3D observer works ...

From a comparison with the associated CAD data, the camera system detects which parts are at which position. The data of the parts to be processed are transferred via XML files (component geometry description). The image processing system determines the gripping points based on the measured 3D coordination. The transmission of the coordinates of the individual parts then takes place (x-, y-, z-coordinates as well as rotating angle +/- 1 mm). The camera is positioned 1.5 m above the measuring surface and achieves an absolute accuracy of less than +/- 1 mm.
