Visual Localization within LIDAR Maps for Automated Urban Driving Ryan W. The Intel® RealSense™ Depth Camera D400 Series uses stereo vision to calculate depth. The problem is hard because the range measurements are received at different times, and errors in motion estimation. Position papers with feasibility studies and cross-modality issues with highly applicative flair are also encouraged therefore we expect a positive response from academic and industrial communities. If num_laser_scans is set to 1 in the Lua configuration reference documentation, this topic will be used as input for SLAM. However, when I try to view the point cloud in ROS, all the points are showing (0,0). In ROS, as a good practice, we usually have a TF tree setup in the following way (at least as a minimum when doing SLAM):. The goal of RLCard is to bridge reinforcement learning and imperfect information games, and push forward the research of reinforcement learning in domains with multiple agents, large state and action space, and sparse reward. This launch file also spawns a rviz window configured to visualize Cartographer's state. Welcome to the ohm_tsd_slam ROS wiki page.
