摘要：

This paper presents an approach to measure the spatial deformation of bone under pressure. A structured-light scanning system is employed to measure the 3D shapes of bone's deforming sequence with accuracy of 0.1mm. A stationary-temperature-distribution (STD) approach is developed to obtain the correspondence of the deforming sequence. The complete continuous-bijective mappings between the object surfaces and a cylinder are made by interpolating between adjacent curves, which contain the correspondence of the same particle on the deforming sequence. The deforming process of the bone is reconstructed and the trajectory of any point on the surface can be tracked. The presented method provides a way to better understand the spatial mechanical properties of bone loading.
