Open eVision Studio: Evaluation, prototyping and development tool
Open eVision Studio: Evaluation, prototyping and development tool

Open eVision Studio is the evaluation, prototyping and development tool of Open eVision. Its intuitive graphical user interface allows you to call and immediately see the result of any of eVision's 2D image processing functions. A scripting functionality generates the corresponding code, which can then be copied and pasted into your application.

Open eVision Studio is free (when using Open eVision 2.0 and above) and does not require any license.

Just click on DOWNLOAD OPEN EVISION STUDIO and install Open eVision. Sample images, manuals and sample programs are included.


Inspection
Inspection

When a template model is ready, the inspection may take place. EasyOCV first locates the marking in the image, allowing it to be translated, rotated and re-scaled or even sheared with respect to the template. After location, grey-level and geometric comparisons are performed and a series of matching scores, called quality indicators, are computed. When these fall outside of given acceptance intervals, a defect warning is reported.


EasyOCV Description
EasyOCV Description

EasyOCV is an optical character verification tool used for mark inspection. It provides automatic training of the model, adjustable acceptance levels and a robust gray-scale analysis. EasyOCV is suitable for various mark inspection and label printing verification applications. It can detect blurred, misaligned, distorted or double marks, extra or missing ink, missing characters or reversed marks as well as contrast problems.


Neo, a New, Flexible Licensing System
Neo, a New, Flexible Licensing System

  • Neo is the new Licensing System of Euresys. It is reliable, state-of-the-art, and is available now under Windows.
  • Neo allows you to choose where to activate your license, either on a Neo Dongle or in a Neo Software Container. You buy a license, you decide later.
  • Neo Dongles offer a sturdy hardware and provide the flexibility to be transferred from a PC to another.
  • Neo Software Containers do not need any dedicated hardware, and instead are linked to the PC on which they have been activated.
  • Neo ships with its own, dedicated, Neo License Manager, which comes in two flavours: An intuitive, easy to use, Graphical User Interface and a Command Line Interface that allows for easy automation of Neo licensing procedures.


Training
Training

EasyOCV first requires training on the particular marking. During this phase, a good-quality template (golden template) is presented to the system. An interactive utility allows defining the structure of the template and related acceptance criteria, in details. The template learnt can be saved for later use. EasyOCV supports the use of several good-quality templates to help with the determination of the acceptance criteria.
