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 functions. A scripting function 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 can be downloaded to evaluate the performance of Open eVision.
Construction of the runs: Segmentation using Grayscale single threshold, Grayscale double threshold, Color single threshold, Color range threshold, Reference image, Image range, Labeled Image or Binary Image
Object construction: aggregation of the runs into objects
Hole construction: aggregation of the runs into holes
Continuous mode for web inspection applications using line-scan cameras
Object selection and sorting according to any feature value
Choose the most suitable Licensing System
Open eVision Dongle-based Licenses: Dongle-based Licenses offer the flexibility to be transferred from a PC to another. To purchase a Dongle-based License, select one of the Euresys dongles (USB or Parallel) plus the license(s) to be stored on this dongle. Licenses are delivered as activation codes, which are stored on the dongles.
Open eVision Software-based Licenses: Software-based licenses do not require any dongle, they are linked to the PC on which they have been activated. Licenses are delivered as activation codes and can be managed online.
The EasyObject library handles image segmentation, i.e. the decomposition of images into separate objects, also called blobs.
Once the objects have been constructed, they can be handled as independent entities. Various geometric parameters or features, such as area, width, or ellipse of inertia, can be computed for each object.
Objects of interest can be selected by means of their position or of their computed features.
EasyObject also supports the inspection of holes in defined objects. Holes are managed as the objects themselves, benefiting from the same geometrical features. EasyObject manages the relationship between objects and holes, defining parent objects for holes.
Object/blob features available
Position: Limit (top, bottom, left, right), Gravity center (X and Y), Weighted gravity center (X and Y)
Extent: Area (pixel count), Feret box (center X and Y, height, width with distinct orientation angles at 22, 45, 68 degrees), Bounding box (center X and Y, height, width), Minimum enclosing rectangle (angle, center X and Y, height, width)
Starting point of the object contour (X and Y)
Object number (index)
Statistics: Pixel gray-level value (average, deviation, variance, min and max)
Ellipse of Inertia: Eccentricity of the ellipse of inertia, Ellipse, Second order geometric moments
EasyObject supports the restriction of the blob analysis to complex- or disconnected-shape regions of the image thanks to the Flexible Masks that are available for the encoding functions. EasyImage can also generate Flexible Masks from an encoded image.
The objects can be drawn onto the source image. The following blob features have a pre-set graphical representation:
Feret box with an angle of 22°
Feret box with an angle of 45°
Feret box with an angle of 68°
Minimum enclosing rectangle
Weighted gravity center
