摘　　要：为确保三维物体视觉重构成像的完整性、提升视觉重构效果,必须有效解决视觉遮挡问题。为此,设计了基于显著特征空间的抗遮挡红外测量方法。首先阐明三维物体视觉重构可视化机理,明确测量距离与极限翻转角函数间的关系,然后利用极限翻转曲面把空间分成外部可见及内部不可见两部分,得到三维物体表面信息。在此基础上,融合超像素特征距离和空间距离对目标区域实施聚类,运用目标空间分布场矩阵匹配全局候选区域,从而构建遮挡检测机制。这一过程中,针对遮挡区域成像较差问题,利用基于改进伪中值的图像滤波方法,在噪声监测时加入像素点灰度值和几何距离等元素,将噪声点从像素点中分离,增强三维成像效果。实验结果表明:该方法抗遮挡性能较好,运算速率较快,能够有效满足三维视觉重构的应用需求。In order to ensure the integrity of 3d object visual reconstruction and improve the effect of visual reconstruction,the problem of visual occlusion must be solved effectively.For this reason,this paper designs an infrared measurement method of anti-occlusion based on the significant feature space.First,the visualization mechanism of 3d object visual reconstruction is expounded,and the relationship between the measurement distance and the limit turning Angle function is clarified.Second,the space is divided into two parts,the external visible part and the internal invisible part,by using the limit turning surface,to obtain the surface information of 3d object.On this basis,the target region was clustered by combining the super-pixel feature distance and spatial distance,and the target spatial distribution field matrix is used to match the global candidate regions,so the occlusion detection mechanism is constructed.In this process,the image filtering method based on improved pseudo-median is adopted to solve the problem of poor imaging in the occlusion area.During the noise monitoring,gray value and geometric distance of pixel points are added to separate the noise points from the pixel points,so as to enhance the three-dimensional imaging effect.The experimental results show that this method has good anti-occlusion performance and fast computing speed,which can effectively meet the application requirements of 3d vision reconstruction.
