Cimtec 3D Surface Inspection

For the full-length version of the video, click here.

Cimtec Engineered Products is pleased to announce the release of 'Cimtec3D' software paired with 3D laser line profile sensors and cameras.  This capability allows us and our customers to move beyond the traditional 2D image inspection to the realm of true 3 dimensional surface inspection.

The 3D laser line profile sensors and cameras provide a scan of the part or surface outputting the full x, y, and z data to Cimtec3D.  They are precalibrated sensors that house the camera imager and laser line generator together for very precise real-world readings.  Cimtec3D has the ability to view and analyze a surface profile-by-profile, or stitch them altogether to view as a 'whole part' scan in a 16-bit grayscale image.  Statistical analysis and other image preprocessing is also applied to the image for nominal surface detection.

The 3D inspection finds surface flaws and reports their location in x, y, and z along with size characteristics such as:  area, length, elongation, spread, and volume.  After inspection, you have the ability to save the 16-bit images with or without the graphical results, and the ability to save the data to csv file.

Lastly, the GUI can be customized for your application and need, including a run-time display with operator interface.

LMI Technologies Announces Gocator Firmware Release 3.3

LMI Technologies has announced the release of Gocator Firmware Version 3.3.  This firmware release is for all series of Gocators, the 2000 series family and the 2300 series family.  The release includes these highlights:LMI Gocator

  • EtherNet/IP:  Gocator is now officially certified for EtherNet/IP use in controlling and communicating with a PLC.  This ensures that the Gocator can be easily integrated with a wide range of PLCs, including Allan-Bradley and Omron, using this industry standard protocol.  No software programming is required!

  • Gap and Flush Measurement Tool:  Measures the distance and flatness between two surfaces. The surface edges can be curved or sharp. The tool is well suited for inspecting panel assemblies in automotive manufacturing plants. Limits can be set to establish pass and fail conditions for inspection decisions.

  • Groove Measurement Tool: Measures the width and bottom of multiple V-shape and U-shape grooves. It can be used to find the vertex for welding applications or inspecting the dimensions of tunnels on a surface, such as the bottom of plastic containers or the treads of rubber tires. Limits can be set to establish pass and fail conditions for inspection decisions.

  • Rotated Box Measurement Tool: Expands Whole Part's bounding box tools to measure the width and height of a rotated object. This can be used to measure the orientation angle, width and height of boxes in packaging applications.

  • Persistent Variables in Script Measurement Tools: Expands the script measurement tool to carry intermediate results from the current frame to the next frame. Users can calculate statistics (e.g. averages) or accumulate results. For example, users can calculate the volume of an object by adding up the area from each cross section.

  • Occlusion Prevention with Two Sensors: Eliminate occlusions by merging data from a main and buddy sensors. Regions that are shadowed by step changes in the surface in both X and Y directions can now be seen, greatly enhancing the accuracy of 3D measurements.

  • Measurement Repeatability Statistics: The number of invalid results and standard deviations are now calculated for each measurement. These statistics provide users immediate feedback on measurement repeatability, greatly simplifying the process of fine-tuning a setup to achieve the most reliable results.

  • Frame Loss Health Indicators: New counters report the amount of data loss due to jitter in external signals when using fixturing or tracking window. Reduces integration effort by alerting users of potential setup problems earlier to reduce the time needed for troubleshooting setup issues.

  • Multiple Control Connections using SDK: The Gocator sensor now supports multiple simultaneous connections from the client computer running the Gocator SDK. This allows one application to be used for changing the sensors’ configuration or the state of the sensor, while at the same time supporting multiple applications for receiving data and health information. Clients can optionally use exclusive connections (i.e. behavior of the previous releases) by using the Go2System_Login command.

Sick IVC 3D Demo setup

3D machine vision proof of concept demo of the Sick IVC-3D.   We inspect a metal bracket with a small 0.5mm imperfection and show the rendered model after the laser scanning.

NOTE:  the screen capture is full screen,  for best results,  right click the "video" link and save the target file, then view the video in quicktime
