多尺度分解及信号融合的3D模型重构
3D model reconstruction based on multiscale decomposition and signal fusion
摘要
Abstract
An improved method based on empirical mode decomposition and signal fusion to reconstruct the geometry model is presented.Firstly, different three-dimension signals are spherically parameterized, transformed to the plane signal and sampled regularly;then the translated signals are decomposed by EMD and waevlet decomposition. The decomposed signals are fused as an image using detail components called Intrinsic Mode Function(IMF) decomposed by EMI and wavelet coefficients by wavelet;At last,the two-dimension signal is inversely mapped to geometry signal. One indicator for three-dimension geometry signal fusion based on SNR is proposed to test the reconstructed model. The rusults show that this method can fuse geometry model efficiently and the effect by EMD is better than that of wavelet.关键词
