Abstract EN
Multimodality image registration and fusion has complementary significance for guiding dental implant surgery.
As the needs of the different resolution image registration, we develop an improved Iterative Closest Point (ICP) algorithm that focuses on the registration of Cone Beam Computed Tomography (CT) image and high-resolution Blue-light scanner image.
The proposed algorithm includes two major phases, coarse and precise registration.
Firstly, for reducing the matching interference of human subjective factors, we extract feature points based on curvature characteristics and use the improved three point’s translational transformation method to realize coarse registration.
Then, the feature point set and reference point set, obtained by the initial registered transformation, are processed in the precise registration step.
Even with the unsatisfactory initial values, this two steps registration method can guarantee the global convergence and the convergence precision.
Experimental results demonstrate that the method has successfully realized the registration of the Cone Beam CT dental model and the blue-ray scanner model with higher accuracy.
So the method could provide researching foundation for the relevant software development in terms of the registration of multi-modality medical data.
