With a total of 5 patents to his name, Taguchi's work has advanced the capabilities of inspection processes in various industries.

Latest Patents

One of Taguchi's latest patents is a non-destructive inspection method and apparatus that utilizes an image signal acquired by a color video camera. This innovative approach allows for the automatic detection of deficiency candidates, including pseudo deficiencies, which are then displayed on a screen for further analysis. The method enables the detection of real deficiencies from the displayed candidates. Additionally, the system stores image data in memory, allowing for repeated reproduction of deficiency information. In this method, chromaticity at each position on an image is acquired, and deficiencies are distinguished from pseudo deficiencies based on chrominance differential values. A polarization filter is employed to eliminate regular reflections during the inspection process, and an ultraviolet-rays cutting filter is attached to the camera to minimize noise during magnetic-particle inspections. This dual functionality allows both inspections to be conducted using a single probe.

Another significant patent involves a method for non-destructive inspection and a digital camera system. This system utilizes a cordless image pickup apparatus that combines a lighting apparatus with a digital camera, ensuring excellent portability. The method allows for image input without being affected by the physical conditions of the inspection object or environment. Marks of known shapes are allocated within the image to facilitate compensation for magnifying factors, position, and tilt. The system generates a total inspection map by continuously applying input data, and a computer executes flaw detection processes, storing results alongside inspection images.
