摘要
通过对摄像位姿的描述和工作特性的分析,运用D-H矩阵方法建立了摄像机坐标系与世界坐标系的对应关系,以达到三维重建的目的;运用运动学模型,推导出摄像摇臂工作时的位姿和运动方程,解决了虚拟3D技术摄像中使用计算机软件系统进行自动跟踪定位的计算问题;设计了基于摄像摇臂运动跟踪算法的应用设计,通过MEMS传感器进行数据采集,并自动控制摇臂摄像,从而为实现虚拟场景与实拍影像之间的有效合成打下了基础。
By describing the position and pose of the camera and analyzing its working characteristics, the corresponding relationship between the camera coordinate system and the world coordinate system is established by using D-H matrix method in order to achieve the purpose of three-dimensional reconstruction. By using kinematics model, the position and pose and motion equation of the camera rocker arm are deduced, and the calculation of automatic tracking and positioning using computer software system in virtual 3D technology photography is solved. An application design based on the motion tracking algorithm of camera rocker arm is designed. Data acquisition is carried out through the MEMS sensor, and the rocker arm camera is automatically controlled, which lays a foundation for the effective synthesis between virtual scene and real image.
