提出了一种简单而高效的方法,以消除虚假痕迹的动态对象的三维点云地图更新。首先,基于视锥过滤器提取视图重叠。然后,我们通过使用KD树的视图重叠的双向搜索获得虚假的踪迹。最后,针对RGB-D摄像机的局限性,运动物体遮挡部分背景的情况,设计了一种基于光线跟踪原理的滤波器来补充整个点云图中缺失的背景。我们的方法可以集成到任何SLAM或3-D重建系统与RGB-D数据输入,它是适用于静态和动态环境。我们验证我们的方法在我们的实验室办公室使用Kinect系统的机器人避障和导航的真实场景。在KITTI里程计基准上的实验结果表明,该方法对动态伪迹抑制和三维地图更新具有很好的效果。
We present a simple yet highly efficient method to eliminate spurious trails of dynamic objects for 3-D point cloud map updating. First, we extract the view overlaps based on view frustum filter. Then, we obtain spurious trails via bidirectional searching of view overlaps using a KD tree. Finally, in terms of the situation where moving objects occlude part of background due to the limits of the RGB-D camera, we design a ray tracing principle-based filter to supplement the missing background in the whole point cloud map. Our method can be integrated into any SLAM or 3-D reconstruction systems with RGB-D data input, and it is suitable for both static and dynamic environments. We validate our approach in real-world scenes of our laboratory office using a Kinect system for robot obstacles avoidance and navigation. Moreover, experiments on the KITTI odometry benchmark illustrate that the proposed approach is highly efficient for dynamic spurious trails rejection and 3-D map updating.
