CV-5000 series

Surface Defect Detection

The CV-5000 Series models are equipped with advanced defect detection algorithms that eliminate many of the instabilities normally associated with surface appearance inspections.

Real-time shade correction [ FIRST IN ITS CLASS ]

Isolates defects for detection on shaded backgrounds

Real-time shade correction isolates defects, even when the background has shadow-like gradations. This filter enables inspections not possible before by cancelling shadows that even lighting techniques could not remove. Unlike commonly used shading correction filters that apply the same correction to all images, this correction adapts in real time to constantly changing shades.

Inspections are difficult due to inconsistent glare on each workpiece

Conventional method

Conventional method

Conventional method (no realtime shade correction, stain mode stability display) Erroneously detects areas of glare as defects.

Real-time shade correction

Real-time shade correction

Shaded areas on the background are cancelled, revealing only the foreign object. Repeatedly extracts only the foreign object, even if the glare has a different shape for each image.

Stain inspection tool [ MOST POWERFUL IN ITS CLASS ]

Introducing the newest standard in surface inspection

The Stain inspection tool searches for scratches and stains by comparing them against the surrounding shade level. Compared to binary processing, this mode has greater tolerance against varying conditions, making it ideal for surface inspections on production lines where individual variation of parts and light intensity fluctuations otherwise present problems. The defect distribution display allows optimised tuning by providing a quick visualisation of how the image processor sees the defect.

Particles on the side wall and bottom of a container.

Conventional method

Conventional method

Conventional binary processing would not be able to detect these particles because of the lack of contrast between the particles and the dark portions inside the container.

However, stain inspection mode ignores the differences in the shade, allowing reliable detection of the particles.

Trend edge defect detection [ FIRST IN ITS CLASS ]

Powerful features for detecting burrs or flaws on profiles

This tool extracts the profile from the edge of a workpiece and uses it to recognise large differences such as burrs or flaws. In addition to geometrical shapes such as circles and straight lines, the tool also recognises complex contours, such as ovals and free-form curves.

Profile trace image: Trend edge detects the profile of the workpiece and automatically generates reference model lines (the green line in this image) consisting of free-form curves.

Burr detection

Burr detection

The burr generates a difference in the distance from the reference line, which allows the tool to detect it.

Flaw detection

Flaw detection

The tool reliably detects even the most subtle nicks along the profile, a defect otherwise considered difficult to detect.

Image enhancement preprocessing filters [ MOST EXTENSIVE AND POWERFUL IN ITS CLASS ]

Powerful defect extraction using original algorithms

The CV-5000 Series features 18 preprocessing filters that highlight otherwise obscure defects. Users can combine up to 13 preprocessing filters in a single window.

Softening filter [NEW]

Softening reduces fine patterns and noise in the background. The softening effect is individually adjustable in the X and Y directions. This filter can be applied to a wide range of applications, including part counting inspections.

Detecting foreign objects on a striped pattern

Original image

This inspection would have been impossible because of the diagonal stripe pattern.

Reliable detection of foreign objects.

Combination of blur and shading correction

It is possible to detect foreign material with diagonal stripes in the background, by eliminating the infloence the pattern.
