In this paper, we examine a method for improving pose estimation by correctly positioning the sensors relative to the scanned object. Three objects made of different materials and using different manufacturing technologies were selected for the experiment. To collect input data for orientation estimation, a simulation environment was created where each object was scanned at different poses. A simulation model of the laser line triangulation sensor was created for scanning, and the optical surface properties of the scanned objects were set to simulate real scanning conditions. The simulation was verified on a real system using the UR10e robot to rotate and move the object. The presented results show that the simulation matches the real measurements and that the appropriate placement of the sensors has improved the orientation estimation.
在本文中,我们研究了一种通过正确定位传感器相对于扫描对象的位置来提高姿态估计的方法。选择了三个具有不同材料和制造技术的物体进行实验。为了收集姿态估计的输入数据,创建了一个模拟环境,在该环境中以不同的姿态扫描每个物体。为扫描创建了激光线三角测量传感器的仿真模型,并设置了扫描物体的光学表面特性以模拟真实扫描条件。使用 UR10e 机器人旋转和移动物体在真实系统上对仿真进行了验证。结果表明,模拟与实际测量相匹配,并且传感器的适当放置提高了姿态估计的准确性。
