Title:
金属材料の結晶組織検査支援装置および支援方法
Document Type and Number:
Japanese Patent JP4524494
Kind Code:
B2
Abstract:

To provide a support device and a support method for inspecting crystalline structure of a metal material or the like capable of processing an image precisely, by correction-processing a noise component and an interrupted portion included inevitably in an original image of a photographed crystal grain, using an algorithm utilizing electric circuit simulation skillfully, and by making the best sufficient use of performance of a "watershed method" suitable for inherent edge image processing.

This support device includes a photographing means 1 capable of photographing the original image P of the crystalline structure comprising the crystal grain S of the metal material or the like, by a microscope 11, and a computer 2 capable of receiving a data of the original image P from the photographing means 1. Brightness of each picture element of the original image P received by the computer 2 is detected by a brightness detecting means 21, and a difference between the brightnesses in the adjacent fellow picture elements, or an edge of the each crystal grain S included in the original image P by inversion of black and white picture elements can be extracted by an edge extracting means 22. The computer 2 includes also an electric circuit simulator means 23.
