The Eye-Vision software from EVT is a machine vision software with a graphical user interface, which enables the user to create inspection programmes with drag-and-drop programming. It has commands that solve every image processing application.

Pattern matching, object detection, object counting, 3D and colour inspection, reading of codes (bar code, QR, DMC), OCR/OCV, robot guidance, bin-picking, metrology and thermal imaging are among the numerous image processing applications the Eye-Vision software is deployed for.

EVT, a specialist in machine vision products for quality control and industrial engineering, says its latest software, which will be showcased at Control among other exhibits, is Deep Learning (EV DL). EV DL is based on state-of-the-art algorithms.

Five process steps to keep up with global competition

02/28/2018 - What is the key to success in times of internationalisation? The WBA Aachener Werkzeugbau Akademie defined process steps that have to be taken in order to gain market intelligence and thus compete on a global market. read...

This year saw the release of Version 3.8, which now provides Deep Learning tools with the company's Eye-Vision software. Easy-to-train neural networks and easy-to-use tools are add-on commands and EV DL tools, EVT adds.

This software, the company notes, is used for the recognition of vehicle number plates and their make as well as the model of the vehicle. It is known as Vecid.

According to Germany-based EVT, the identity of vehicles is perceived by convolutional neural networks, which are already pre-trained. Vecid tells one exactly which type of vehicle has just passed through the gate of a garage and it also reads the number-plate of the vehicle based on the trained CNN, which saves the nuisance of configuring a conventional OCR reader system.

Comprehensive Eye-Vision 3D commands on display

Another software to be presented at Control is Eye-Vision 3D, which has a new parallel processing function and thus offers commands, for example, for bin-picking, welding seams or performing adhesive bead inspections. In bin-picking, the software notes the shapes and positions of objects that it has been trained to remember. It can thus locate unsorted parts in a box and pick them up with, for example, a robot gripper. Eye-Vision 3D also sends the information on the position of each detected part in the box to a robot.

Eye-Vision 3D Profile-Match, the company says, offers commands that scan profiles and measure these profiles to check for errors such as holes and warts on weld seams and adhesive beads. Other functions include detecting profiles, which work even when the height of the profiles do not match. With this function, cracks, holes, warts and fusion lack can be detected as well.

The 3D Unrolling command of the EyeVision 3D software straightens 3D point-cloud images of tilt-scans and/or is able to “unroll” them, respectively. Examples hereof include a tilt-scan in which a laser triangulation sensor is rotated, or used with a laser line to scan a large area without the hindrance of a large linear axis.

Six fields of action for successful automation

Cost effective: Space-saving and fast processing

Eye-Vision Parallel Processing allows for multiple run-times with several 2D cameras and 3D sensors, simultaneously with each separate inspection programme. Furthermore, it only requires one computing unit and Eye-Vision software. Given the appropriate computing capacity (a minimum of a dual-core processor), the system enables faster processing, which apart from needing less space is also more cost-effective as it saves the need for additional hardware and software.

At Control, EVT will be in Hall 6, Booth 6110.
