(2) utilize the camera be installed on the metaloscope on the measurement cross section of metal sample to be measured, to have the ken to have a common boundary comprehensive collection of metallic phase image to the lower right corner from the upper left corner, and with each minute ken metallic phase image be transferred to computing machine;
(3) computing machine each minute of receiving camera transmission identifies automatically, stores behind the ken metallic phase image signal;
(4) treat that rotary encoder is measured the position of feedback and shown that camera has been finished whole scannings to each minute ken after, stop the image acquisition of camera to metallographic sample to be measured;
(5) there is the border of the branch ken metallic phase image that the ken has a common boundary to discern automatically by computing machine to above-mentioned storage whole, and finish the seamless spliced of whole minutes ken metallic phase images automatically, thereby obtain a true and unique comprehensive metallic phase image of containing whole measurement cross section;
(6) carry out metallographic examination by computing machine according to the method for standard code, and finish the metallographic examination report according to the magnitude calculation method that defines in the standard.
Metallic phase all-round measurement method provided by the invention is to utilize the metallic phase all-round measurement mechanism that all kens of whole metallographic sample to be measured are carried out comprehensive metallic phase image collection, automatically carry out these metallic phase images seamless spliced by computing machine then, thereby obtain a comprehensive metallic phase image, and finish the metallographic examination report automatically.Because the measurement result that is obtained is true and unique, thereby accuracy is good, so can not cause harmful effect to practical application.
