为解决工程中齿轮轴系装配误差的测量难题,提出了一种基于立体视觉的齿轮轴系装配误差测量方法。该方法以布置在待测特征上的圆形标记点为媒介,通过三维重建与数学拟合,获取相应特征的空间位姿,进而计算装配误差。以某锥齿轮箱为对象,给出了所提方法的完整技术流程,并系统研究了状态数量和靶标盘安装角度对拟合精度的影响。开发了完整的软硬件系统,通过实验,验证了测量方法的有效性与高效性。
In order to solve the problem of measuring the assembly error of gear shafting in engineering, a method of measuring the assembly error of gear shafting based on stereo vision is proposed. In this method, the circular mark points arranged on the feature to be measured are used as the medium to obtain the spatial pose of the corresponding features through 3D reconstruction and mathematical fitting, and then the assembly error is calculated. Taking a bevel gearbox as an example, the complete technical process of the proposed method is given, and the influence of the number of States and the installation angle of the target plate on the fitting accuracy is systematically studied. A complete hardware and software system is developed, and the effectiveness and efficiency of the measurement method are verified by experiments.
