在原有三维模型检索方法的基础上提出了加入特征权值进行三维模型检索的方法,并将此方法应用到基于球面调和的三维模型检索中。通过以采样球面积为比例逐渐增加外部球面的采样权值来平衡采样不均匀对检索效果的影响。在PSB测试集上进行检索实验,并使用多种评价指标进行对比。实验结果表明,加入特征权值后检索效果优于原始方法。

Based on the original 3D model retrieval method, the paper proposes a method for 3D model retrieval adding weighted feature, and this method is applied to 3D model retrieval based on spherical harmonic. The effect of the retrieval exerted by the uneven sampling is proposed and balanced through increasing the proportion of sampling weights of the external sphere gradually which taking the ball of sampling area as ratio. The retrieval experiments are carried out on PSB and compared using a variety of evaluation. Genera/results show that the proposed method is more effective than the original one.
