Influencing factors for 2D image generation
Even with the same lighting technology, the inspected object itself has the greatest influence on the resulting video image to be precessed later.
Three key factors are responsible for this:
1. Colour
Material colours colours (transparent, semi-transparent, white, red, green, ..., black)
2. Shape
The macroscopic shape properties, e.g. surface geometry (planar, stepped, inclined surfaces, spherical, cylindrical, etc.) have a very large influence on image generation
3. Texure
The microscopic shape properties are also important (and often cause the most difficulties)
- Interactions of light with the material characteristics (plastic, metal, glass, ceramics, etc.)
- Surface texture (parallel brushing, circular brushing, grooved, porous, smooth, rough, fibrous, etc.)
Typical: Complex components
- Different shapes
- Colours
- Materials
- Surface textures
Direct light
Diffused light
Images: Difficult to illuminate, shiny metal workpiece with a largely flat surface.
