EyeCheck Smart Camera – the Eye for the Robot
Throughout the world robots are used for applications such as packaging, soldering, adhesive bonding, coating, etc. The robots are usually equipped with smart cameras, such as the EyeCheck 1000 series from EVT. Due to the recent advances in image processing, application areas have increased.
EyeCheck Smart camera series from EVT offers a combination of a camera and Eye Vision evaluation and processing software. The camera housing contains the lens (the user can chose between 6 mm, 12 mm and 25 mm lenses) and the illumination (available in different colors). The EyeCheck 1000 is available in various resolutions, from 782 x 485 pixel up to 1280 x 1024 pixel, and contains the full command set of EyeVision software.
The EyeCheck systems can be used for robot positioning and object detection, custom-made solutions for position correction, and can be mounted onto articulated robots. The moving or stationary objects are illuminated with the camera-based LEDs. Thanks to the robust evaluation algorithms, EyeVision software delivers reliable results even in difficult environments.
EyeVision software also has commands for code reading, color and surface inspection as well as commands for measuring objects. The system is configured and controlled by the user via the graphical user interface. The drag-and-drop programming allows an easy adjustment to different objects. EyeVision software can be connected to an external computer or the control system of a plant via Ethernet or PROFINET. Applications such as position control can be used in combination with inspection, measurement and identification tasks.
EyeVision 3 with New PlugIn System
The EyeVision 3 machine vision software is more flexible than ever. With the new plugin concept, third party software such as Halcon, Open CV or the Euresys library can be integrated into the EyeVision software library.
Using the new SDK for plugin development, it is easy to integrate evaluation routines into EyeVision. EyeVision supports x86 Windows, Linux, as well as ARM based Linux systems.
With the GUI designer and only a few mouse clicks, the user can open their own routines or the library routines of a third party maker without special programming skills.
Also the standard communication components allows easy integration into SCADA and PLC systems. This means, for example, that the OPC standard can use EyeVision software as an OPC server. With that the accumulated data (measurement data, position, etc.) can be sent to a client.
Additionally, the new Webshop from EVT makes it possible to offer plugins directly to other EyeVision software users.
New EyeSens ZQ Vision Sensor with powerful ZYNQ hardware
The EyeSens ZQ vision sensors from EVT are much smaller than the standard EyeSens sensor. Despite the miniature design, they are powerful, due to the ZYNQ processor with dual Core ARM, and can solve image processing tasks faster than common vision sensors. Because of its small size, light weight and integrated lighting, the EyeSens ZQ is well suited for locations such as a robot arm.
Suitable applications are:
- Code reading (DMC, QR, Barcode)
- OCR/ OCV
- Color Inspection
- Measurement Technology
- Pattern Matching / Contour Matching for Robot Vision
- Counting Objects
The EyeSens ZQ is available with EyeSens software as well as the complete EyeVision software platform. Additionally, the camera features the option of an integrated FPGA, which is important for the fast preprocessing of image information.
The creation of an inspection program is also very easy with the drag-and-drop graphical user interface; there are no programming skills needed.
Crown Cap Inspection with EyeVision Image Processing Software
EyeVision software contains commands for various measurement technology applications, for pattern matching, for code reading, for object counting as well as error detection such as scratches, holes, cracks, contaminations, printing or color errors, etc., which makes it ideally suited for use in the bottling industry.
EyeVision software can inspect the fill level, detect if bottles are without caps, or check the correct position of the label. It also offers the opportunity to inspect using 3D, for example, to check that the cap is installed properly.
EyeVision software supports various 3D sensors such as the EyeScan AT 3D and contains commands for evaluating point clouds and grayscale images. The EyeScan AT 3D has a profile resolution of up to 4096 points/profiles (4k Ultra-HD) and integrated 3D evaluation algorithms with up to 25 kHz and a robust enclosure with IP67 and M12 connectors.
Track & Trace for the Pharmaceutical Industry
EVT presents the new Track and Trace image processing system for the pharmaceutical industry. EyeTrace was developed to prevent forged pharmaceutical products from entering the supply chain and assures the traceability of the drugs.
EyeTrace, using an industrial camera and EyeVision image processing software, can detect more than the human eye. EyeTrace makes the inspection of security features on the packaging easier and can identify every single package.
Eye Vision can also read codes: bar code, QR, or DMC. With the code reader function, EyeTrace can read:
- Code of the drug maker
- serial number
- A national number for the reimbursement of costs
- Charge number
- Expiration date
Besides the code reader function, EyeTrace can be extended with other commands within the EyeVision software tool set.
EyeCheck Thermo in New Housing
The first intelligent thermal imaging camera – EyeCheck Thermo from EVT – is now available with protection class IP65 or IP67, making it optimally suited for industrial use.
Inside the compact housing is a user programmable FPGA. The integrated ZYNQ board is available for application programming. It is also possible to use different ZYNQ boards, corresponding to the needs of the application.
The EyeCheck Thermo has eight 24v inputs and eight 24v outputs. By using the additional thermal command set, complex applications for the thermal imaging area can be solved quite easily via drag-and-drop-programming.
Detecting Packaging Flaws with EyeVision
To present food neat and appealing for the customer, flawless packaging is very important. The wrapping is not only to protect the product during transport; packaging also is important in the placement of the product on supermarket shelves.
In one current application, EVT’s EyeCheck 1xxx series was used to inspect bags of separately wrapped candies to make sure that they did not slip into the heat-sealed ends of the bag. With the drag-and-drop functionality of the software, the customer can easily create their own inspection program without programming skills. Additionally, the user can add color inspection commands to the software and then the candies can also be inspected for the correct colors.
EyeSens with OPC Support
The EyeSens systems from EVT can now also serve as an OPC (Open Platform Communications) server. The OPC standard allows the EyeSens sensors and the EyeVision software to function as OPC server. Detected data such as measured values are now easily sent to a client. The user can determine which data should be sent to the OPC client using the standard interfaces, RS232 or Ethernet. As with other EyeVision software operations, the OPC integration is possible with the drag-and-drop function.
An example would be the EyeSens Bottle Inspect (BI) measures the fill level and sends this data via OPC to the SCADA (Supervisory Control And Data Acquisition) system. Based on this measured data the SCADA system can regulate the fill level and also display the data graphically.
EyeVision 3.1.12 LTS – Image Processing Software Now With Profinet
EyeVision image processing software 3.1.12 LTS now supports Profinet and an SQL data base, making it ready for Industry 4.0. Besides the revised color inspection commands, the Code Reader was also extended (DMC, bar code, QR, etc.).
The complete EyeVision command set is available and the system can be used for measurement technology, code reading, OCR/OCV, object detection, surface and color inspection, pattern matching, 3D and Robot Vision, etc. Using the Graphical User Interface (GUI), inspection programs can be put together by selecting the graphical tools and commands.
The new EyeVision 3.1.12 has added commands for 3D measurement and filter commands directly available. Current EyeVision users will find that the toolbox is better arranged. Self-arranged commands can be integrated into the EyeVision GUI which simplifies the process of putting together an inspection program.
