Indirect visual inspection
In indirect visual inspection, the area to be inspected is captured by a camera and displayed on a monitor. The test image can be subjected to further work steps. For example, the image can be enlarged, details can be visually highlighted for analysis reasons or the image can be saved for documentation purposes. By displaying on a screen, several people can judge.
The trend is towards indirect visual inspection, as the use of camera technology offers more possibilities and leads to more efficient interruption of the production process. The indirect visual inspection is carried out e.g. by means of videoscopes or stationary inspection solutions. In industries with high quality requirements, inspections solutions are used, that provides high resolution images.
Advantages of indirect visual inspection
- Digitalization enables image optimization for better defect evaluation
- Secure 100 % controls
- Defects can be documented
- Better analysis possible
- Tracking of documented defects for process optimization
Disadvantages
- Acquisition costs higher than with direct visual inspection
- More space required than with direct visual inspection
