摘　　要：多媒体图像控制点的定位精度相对较低,导致后期的三维点云配准效果不够理想,且耗时较长。因此,本文提出基于Cult3D的多媒体图像三维点云配准方法研究。以像素边缘垂直于梯度方向直线为基准,利用Cult3D获取目标控制点到该直线的距离以及角度信息,计算出精确的控制点位置信息,并考虑到不同图像的像素差异,制定了个性化的数据获取标准,结合定位结果,采用一致性计算的方式实现对图像的快速配准。测试结果表明,设计方法对于控制点的匹配正确率可以达到98.87%以上,且耗时得到明显控制。The positioning accuracy of the control points of multimedia images is relatively low,which leads to unsatisfactory and time-consuming 3D point cloud alignment at a later stage.Therefore,this paper proposes a research on the 3D point cloud alignment method of multimedia images based on Cult 3D.Taking a straight line with the pixel edge perpendicular to the gradient direction as the reference,Cult 3D is used to obtain the distance and angle information from the target control point to the line,calculate the accurate control point position information,and develop personalized data acquisition criteria considering the pixel differences of different images,and combine with the positioning results to achieve fast alignment of the image by means of consistency calculation.The test results show that the design method can achieve more than 98.87% correct matching rate for control points,and the time consumption is significantly controlled.
