摘　　要：针对因建筑物超时空目标信息特征量大,三维重建时细节丢失严重,导致目标复原难度大的问题,提出一种基于虚拟现实的建筑物信息复原方法。采用矩形法计算摄影成像平面与建筑物平面间的矩形四边和顶点参数,求解矩阵平面的平移向量并分析同步关系,将其作为建筑物三维建模的数据比例参照。根据建筑物二维图像的细节信息,分层处理图像,计算目标信息与周围位置的光影和像素差值,按照差值实行信息补偿。针对建筑物超时空不受空间和时间限制特征,采用虚拟现实中的仿真技术建立建筑物三维模型,将补偿后的二维信息输入至仿真软件中,实现建筑物目标信息复原。实验结果表明,所提方法复原精准度较高,建筑物测量值与真实值吻合度较高,复原耗用时间较短,具有一定的实用价值。In order to solve the problem of serious loss of details in the three-dimensional reconstruction of buildings and the difficulty in target restoration,a method of restoring the building information based on virtual reality was proposed.Firstly,the rectangular method was used to calculate the parameters of the four sides and vertices of the rectangle between the imaging plane and the building plane.Secondly,the translation vector of the matrix plane was solved,and then the synchronization relation was analyzed as the data proportion reference for three-dimensional modeling.According to the details of the two-dimensional image of the building,the image was processed layer by layer.Thirdly,the difference of shadows and pixels between the target information and its surrounding position was calculated.On this basis,the information compensation was completed.The hyperspace and time of buildings were not limited by space and time,a 3D building model was built by simulation technology in virtual reality.Finally,the compensated two-dimensional information was input into the simulation software to realize the restoration of building target information.Experimental results show that the proposed method has higher accuracy in restoration,higher conformity between the measured value and true value,and less restoration time.
