PURPOSE:To attain a high speed and low cost processing by forming a three dimensional connecting information table based on the two dimensional label information of respective tomographic images and the interlabel connecting information of the respective tomographic images and three dimensionally labelling. CONSTITUTION:The tomographic image obtained from a tomographic image forming device is binarized by a certain threshold by a two dimensional labelling means B to divide to respective areas, the plural labelled tomographic images are overlapped in a variable density gradation direction by a two dimensional histogram measuring means C to measure a two dimensional histogram and obtain the interlabel connecting information beteween the tomographic images of the respective labelled areas. The three dimensional connecting information table is formed based on the two dimensional label information of the respective tomographic images divided to the respective areas and the interlabel connecting information of the respective tomographic images by the use of a three dimensional connecting information table forming means D to three dimensionally label from this three dimensional connecting information table. Thereby, a three dimensional labelling device in which a processing can be attained at high speed and the cost of which is low is obtained. |
