基于声矢量传感器阵列的二维来波方向估计是水声通信的关键技术,但阵列增益的不一致性将影响来波方向估计性能。基于子空间分解,提出一种阵列增益和来波方向的联合估计算法,其中来波方向利用旋转不变性求解,阵列增益利用子空间正交性求解。来波方向和阵列增益以迭代方式求解。仿真结果显示了算法的有效性。
The two-dimensional direction of arrival estimation based on acoustic vector sensor array is the key technology of underwater acoustic communication. However, the inconsistency of array gain will affect the performance of incoming wave direction estimation. Based on subspace decomposition, a joint estimation algorithm of array gain and direction of arrival is proposed, in which the direction of arrival is solved by invariance of rotation and the gain of array is solved by subspace orthogonality. The direction of the incoming wave and the gain of the array are solved iteratively. Simulation results show the effectiveness of the algorithm.

现有三维模型融合方法多采用对原有三角面片顶点重新构网的方式,容易导致原有模型几何特征丢失及纹理失真等。本文针对倾斜摄影模型自身特点,提出了一种模型精细融合方法。首先,以一个模型作为中心模型,并以另一模型与中心模型外轮廓的空间关系计算融合区域;然后,以中心模型外轮廓作为约束,对原始模型三角面片进行精细剖分;最后,基于精细剖分的三角面片进行纹理坐标的插值计算。以实际倾斜摄影数据进行试验的结果表明,本文
