Disys is able to meet the customer's needs by providing 3D scanning systems that best fit the specifications of the object to be acquired and inspected .
The solution mainly used is with laser blade technology. In addition to using commercial products to develop our work, we design and develop custom laser scanners!
Through this technology the scanner reconstructs a single "slice" of the object (projection on the X-Z plane [width-depth]). The last component (Z [length]) is instead obtained by knowing the forward speed of the object (if constant) otherwise through the data obtained from an encoder.
Structured light scanner
Structured light 3D reconstruction systems, on the other hand, give us the possibility of reconstructing a point cloud even with detailed resolution (precision even lower than a tenth of a millimetre) without the need to move the object as required by laser blade 3D scanners.
The 3D data acquired in this way is then processed by specially developed software. The analysis performed can vary between volume calculations, dimensional checks, curvature measurements, bending angles, defect detection, etc.
Kinect and scanners
Disys also uses Kinect and structured light Scanner to develop highly customized applications on customer needs. Kinect systems offer the advantage of non-invasive capture (no lasers or visible projected light) and allow us to capture large volumes in 3D.
Time of Flight Cameras
Disys also uses time of flight (ToF) cameras to develop applications using non-invasive acquisition (no laser or visible projected light) and which can be used for objects of considerable size.
ADVANTAGES OF VISION SYSTEMS FOR QUALITY CONTROL
Artificial vision systems drastically reduce the time needed for inspection and quality control, allowing to speed up production and increase profits.
With high resolution cameras, scanners and sensors it is possible to obtain high precision measurements and quality controls which is highly impractical by a human operator.
The operator cannot always guarantee constant quality control due to distractions and tiredness. Furthermore, there is a subjective component in the evaluation where the same piece could be rejected by two different operators.
It is not always possible to carry out quality controls: either because the spaces are too narrow, or because they are too dangerous. The vision systems have small dimensions and can be applied even in the most hostile environments.
Processing of statistics on rejects and type of defects to visualize the problems related to the production line and understand the defects in production.
Saving of the history of the images and acquisitions of the pieces produced in order to be able to validate or contest any non-conformities.
