EyeVision software from EVT now offers EyeMeasureEasy (EME), an intuitive image analyzing tool. The user can directly measure and analyze image data with only a few mouse clicks. The tool can be used for applications in microscopy. The features of EME can be extended, so that it can be integrated into a fully automated, industrial inspection process.
With EyeMeasureEasy the user can display live-images, and can save images and load them from memory. There are several different measurement options that can be carried out on those images, such as:
- Angle including three points or four points
- Distances between two points
- Radius of circles including three points or n-points or automatic
The measured results can be shown via a text overlay, list boxes or charts. The measurements can be controlled by the user through “start” and “stop” buttons, or the measurements can be carried out in a free-running measurement.
The camera options can be set directly and the user interface is a design framework for a customized graphic user interface.
EyeVision software provides the integrated “brain” of the 3D sensor. EyeVision allows the sensor not only to capture an image but also to use the complete 3D command set of the software to measure, compare and read the 3D point cloud or 2D gray-scale image.
The Gocator is a compact sensor in an industrial housing with a protection class of up to IP67. It has two digital outputs, RS485 Serial and one analogue output (4 – 20 mA). More than one of the Gocator sensor families can be used with effortless configuration and synchronization.
With the EyeVision machine vision software the sensor has various commands available. Starting with the “3D Blob” command which is very versatile and can be used count objects within a point cloud, the software contains commands to measure openings (holes, slots), cylinder, studs (threaded and non-threaded), plane, etc. It has also 3D volumetric tools: volumes, areas, bounding boxes, positions (min, max, centroid), ellipses, orientations, etc.
Additionally, the 3D-software now also has a “RectProbe” command to find edge-points in a certain direction and returning the detected edge. This can be useful for additional measurements on the point cloud. There are also various filter commands such as “Merge”, which merges two point clouds into one, or the filter command “Outlier Removal”, which removes all points that deviate in Z-direction from their neighbors by a certain amount. Also important is the “Voxelgrid” filter, which down-samples a point cloud using a voxel grid and outputs points that are the average of all points inside a voxel. The filter can make unordered point clouds into ordered.
EyeVision software utilizes a graphical user interface. The commands can be drag-and-dropped in a program editor, where the inspection program can be created, even without programming skills.
FSI Advanced Research will be participating in the 2017 South Carolina Automotive Summit, February 20-22, in downtown Greenville, as part of the South Carolina Auto Week. For more info, click here.
The EyeScan AT 3D sensor – together with EyeVision image processing software can inspect the correct position of pins and check for the quality and position of balls on a Ball-Grid-Array. The connectors of BGAs can be inspected with the 3D sensor for various characteristics up to an accuracy of a micrometer (µm).
Thanks to the Scheimpflug-projection, the laser line stays focused and distortion-free. Even in a high-speed application, the captured images have a high resolution, and no lens distortion correction is needed. Every single bump of the BGA is inspected for its size and shape up to a µm-accuracy.
The EyeScan AT utilizes precision laser line measurement (or laser triangulation). The camera views a laser line, which is projected onto the component (in this case: the BGA) and calculates the height information from the laser line profile.
Utilizing a precision blue laser and on board FPGA the EyeScan AT 3D is capable of over 20,000 profiles per second with very high resolution to capture even the finest details. Additionally, the High Dynamic Range algorithm with threefold exposure allows inspection of bright and dark objects in the same scan without loss of speed.
3D image information is processed by the powerful EyeVision software which is programmed though an intuitive drag and drop interface.
FSI Technologies and Automation Technology will be exhibiting at the 2017 Automate Show, to be held in Chicago, April 3-6. Please join us in booth 2552 to see the latest in high speed 3D sensors and machine vision technologies.

EyeVision software by EVT now also supports a 3D laser triangulation sensor with blue laser. The new EyeScan AT 3D scanner is especially suitable for scanning metal or metallic surfaces.
Today’s noncontact 3D scanners include one of two laser types: blue laser or red laser. Most 3D scanners, including EyeScan 3D scanners from EVT, user red laser technology. The new EyeScan AT 3D Blue, however, utilizes optically superior blue laser technology.
The blue-violet Laser has some clear advantages which provide better scan results. Because it has a shorter wavelength than a red laser, a blue laser delivers improved scanning results with higher resolution and up to a 50-percent reduction in data noise. The shorter wavelength creates a smaller laser speckle pattern, generating a sharper depth image. The blue laser is more effective when scanning metal, because a blue laser is narrower and finer than a red laser line.
Thanks to 20,000 profiles per second and the new blue laser, even complex component parts and surfaces can be captured with high accuracy. The extremely fast scans are possible due to the short exposure time and the preprocessing of data with a FPGA inside the scanner. The high dynamic range algorithm with triple exposure makes it possible for dark and bright objects to be inspected in one scan, without a decrease in speed.
Medical products undergo a number of quality and safety inspections and have explicit markings and identification. EyeVision image processing software is often used to inspect markings on medical products. A camera inspection system consisting of an EyeCheck smart camera, which includes EyeVision software, can be integrated permanently into the laser marker head, ensuring an accompanying image capture for verification and validation of the quality.
EyeVision software can read markings such as:
- alphanumeric characters such as serial numbers, date specification, etc.
- complex codes such as bar codes, 1D and 2D Data Matrix Codes (DMC)
- company and brand logos
EyeVision software inspects the markings, ensuring consistent quality. Also, the contents of the codes can be inspected. The software includes commands for code reading as well as pattern matching, position, and measurement technology. This is especially important as the code is used for the product identification, traceability, product safety and quality.
The EyeCheck smart cameras are available in various variations and can be equipped according the production process and production line, with diverse sensors and lenses. All EyeCheck smart cameras have one thing in common: the EyeVision software. The software can be mastered in no time at all without special programming skills. Due to the drag-and-drop function and the self-explanatory graphical user interface, inspection programs can be created easily for reading complex codes and characters.
The EyeSens DMC Code Reader from EVT is a compact vision sensor with integrated lens and illumination. There are three different resolutions: 736 x 480, 1024 x 768 and 1280 x 1024 pixels. The EyeSens has a 1/3“ CMOS sensor and interfaces with Ethernet, RS232 and RS422. The lens can be in 6, 12 or 25 mm.
The EyeSens DMC can also be equipped with the QR-code reader command. The codes are evaluated by EyeVision image processing software. The drag-and-drop programming does not require programming skills and the code reader command is easy to adjust in the graphical user interface. The user can also design their own interface, using the process mode.
