  • EasyLocate Interest Point : New working mode (alternative to EasyLocate Axis Aligned Bounding Box) simplifying the annotation of the dataset and the configuration of the tools when all objects have the same size. A single click is enough to annotate an EasyLocate Interest Point object.
  • EasyGauge : New Polygon Gauge in addition to Point, Line, Rectangle, Circle and Wedge gauges.
  • Deep Learning tools now supporting GPU processing on NVIDIA Jetson.
  • Faster compilation time with simplified C++ headers and reduced calling cost to the Open eVision API.


Detection of 3D objects in point cloud and ZMap
Detection of 3D objects in point cloud and ZMap

Easy3DObject uses an innovative algorithm to detect objects in Point Clouds or ZMaps. It is able to efficiently extract small and large objects, whatever their shape.

Compute precise 3D measurements, such as size, orientation, area, volume…

For each object detected, Easy3DObject computes 3D geometric measurements. All measurements are expressed in real-world units (such as millimeters or microns). These values include the length, width and height of the object, the orientation and tilt angles, the area and the volume. These measurements can then be used to perform 3D inspection, for example by comparing the results with reference values.


Full featured interactive demo application
Full featured interactive demo application

A demo application for Easy3DObject is provided with complete source code. Using that application, the user will be able to learn and experiment with all the features of the Easy3DObject library. Additionally, code snippets can be generated and integrated into their applications.

Metric detection criteria
Metric detection criteria

The 3D object detection algorithm uses several geometric criteria to focus only on the required objects. These criteria are the size (length, width and height), the angle (orientation and tilt), the aspect ratio, the area and the volume of the objects. These parameters are expressed in real-world coordinate units. Using these criteria, the user can limit the extraction to the objects relevant to the inspection.


Automatic extraction of object local supporting plane
Automatic extraction of object local supporting plane

For each object detected, Easy3DObject extracts the local supporting plane. It is then used as the reference for various calculations like height, top position or volume. Using only the area surrounding the object in this process makes Easy3DObject a powerful tool for the inspection of products with curved or non-flat support.


Neo Licensing System
Neo Licensing System

  • Neo is the new Licensing System of Euresys. It is reliable, state-of-the-art, and is now available to store Open eVision and eGrabber licenses.
  • Neo allows you to choose where to activate your licenses, 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 computer to another.
  • Neo Software Containers do not need any dedicated hardware, and instead are linked to the computer 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.


Easy3DObject Description
Easy3DObject Description

Easy3DObject is a library able to automatically extract and measure 3D objects from a Point Cloud or ZMap. Easy3D is required when using any Open eVision's 3D library and is provided when purchasing Easy3DLaserLine, Easy3DObject, Easy3DMatch or the 3D Bundle.


Compatible with arbitrary regions
Compatible with arbitrary regions

The arbitrary region feature of eVision (ERegion) can be used with Easy3DObject to refine the domain of extraction. Rectangles, circles, ellipses, polygons or any arbitrary regions are available as an optional parameter to the extraction.


2D and 3D graphical display of the results
2D and 3D graphical display of the results

The resulting object list can be displayed in 2D and 3D graphical contexts. On an image, the objects can be shown with their bounding rectangle, average position or extracted pixels. On a 3D Viewer, the objects are displayed with their bounding boxes, planes or top positions. Display attributes like color or opacity are customizable.
