A NEW DIMENSION OF INSPECTION TECHNOLOGY.

3D particle inspection of highly viscous pharmaceutical products

With the common camera inspection it has always been a challenge to distinguish between inside and outside contamination of pharmaceutical containers filled with highly viscous products. Seidenader has now developed a special method for inspecting these products: a completely new approach, but based on the same hardware.

3D inspection principle

The common particle inspection in liquid products is based on the fact that particles can be whirled up by rotating the container and stay in motion when the rotation of the container is stopped.  With highly viscous products this does not work. High viscosity makes particles stay in the same position and thus they cannot be distinguished from outside contamination of the container when using the common method.

With our "3D inspection" the third dimension comes into play. Accurate positioning and detailed data of the container, together with real images taken by mega-pixel cameras as well as virtual images created through assumptions, provide the basis for complex calculations:

  • The camera takes a real image - but from this it is impossible to clearly identify what is inside or outside the container.
  • To eliminate the outside contamination from the picture we make assumptions and compare them with reality:
  • It is assumed that all particles which are visible in the real image are outside on the back surface of the container. A calculation is now carried out to see how the image would look after rotation by a defined angle.
  • In the next stage, it is assumed that all particles from the real camera image are on the front surface of the container. After the same defined rotation the image would look like the generated virtual image of the front surface.
  • Both virtual images are compared to the second real image taken after the defined rotation. A particle in the real image that matches with one particle in one of the virtual images will be masked.
  • The resulting image only shows unmasked particles, i.e. those that are inside the container.
