Generation of 3-D Models Based on Image Fusion of Range Data

چکیده
This paper presents a method for measuring the entire three dimensional (3D) shape of object, which is applicable for 3D digitizing into a solid modeling CAD. The method measures the complete surface model of the object automatically and in the non-contact way. The method employs two range finders and a turn-table cooperatively: a fixed range finder using a turn table measures rough surface data of the objects, and a hand-eye range finder finds the deficit of surface data due to self occlusion and makes it up by changing to it. The 3D shape is represented in an extended octree in computer. The octree representation allows us to keep more precise shape in smaller memory storage. An experimental system based on the method shows us the good flexibility and performance of the method for 3D digitizing.

متن کاملMultimodal medical image fusion based on Yager’s intuitionistic fuzzy sets
The objective of image fusion for medical images is to combine multiple images obtained from various sources into a single image suitable for better diagnosis. Most of the state-of-the-art image fusing technique is based on nonfuzzy sets, and the fused image so obtained lags with complementary information. Intuitionistic fuzzy sets (IFS) are determined to be more suitable for civilian, and medi...
