I have two web cams and using openCV and SBM for stereo correspondence I get point cloud of the scene, and filtering through z I can get point cloud only of object. org with rtabmap or rtabmap_ros tag. 3D SLAM , ROS + rtabmap+ZED stereo+ ZED Visual Odometry+imu+ Wheel Odometry +GPS - Duration: 7:13. a community-maintained index of robotics software Changelog for package sensor_msgs 1. OK, I Understand. In the case of the xacro file there is a pan and tilt servo setup. This allows the point cloud data to be positioned correctly regardless of where the head is. ") RTABMAP_PARAM (Rtabmap, PublishLastSignature, bool. The environment is modeled by a RGB-D dense SLAM algorithm, for example, RGBD-SLAM , RTABmap and etc. pcd_ros_segmentation might still link to the system-wide installed version of pcl_segmentation. /rtabmap/cloud_map (PointCloud2) is assembled by rtabmap node with Grid parameters ($ rtabmap --params | grep Grid/).

Built software to get the interactive point cloud around the robot arm from Kinect depth camera using PCL and Rtabmap, then integrated the point cloud with motion planning node in ROS, and. This dataset was gathered entirely in urban scenarios with a car equipped with several sensors, including one stereo camera (Bumblebee2) and five laser scanners.
