Hi,
I was actually meaning that by changing parameters in the launch file, they wouldn't reflect in the terminal. But I solved that. In any case, i decided to drop using the sensor_fusion.launch file and instead I will use with the robot_localization ekf_template.launch and the rtabmap.launch. I am using my own launch files named ekf_template_ugv.launch and rtabmap_ugv.launch I read in this link https://answers.ros.org/question/317419/realsense-d435-rtabmap-pixhawk-imu-robot_localization/ that you said the rtabmap.launch is tied to using visual odometry directly ignoring r_l odometry so I am now trying to change this by modifying the rtabmap_ugv.launch file. The changes i made so far: <arg name="frame_id" default="base_link"/>instead of camera_link<arg name="queue_size" default="100"/>instead of 10<arg name="wait_for_transform" default="0.3"/>instead of 0.2Then i changed my rgb, depth and camera info topics. (I am using a D435). I also changed: <arg name="rgbd_sync" default="true"/><arg name="vo_frame_id" default="odom"/>I added this argument: <arg name="r_l_odom" default="/odometry/filtered/local"/>which is used further down to the visual SLAM node as : <remap from="odom" to="$(arg r_l_odom)"/>I am also attaching the compete rtabmap_ugv.launch file: <?xml version="1.0"?>

Your RGB-D sensor should be already started with "depth_registration:=true".

Your camera should be calibrated and publishing rectified left and right

</launch>and some screenshots:   When the camera is static, I get: The time difference between rgb and depth frames is high (diff=0.033357s, rgb=1692189046.376037s, depth=1692189046.409394s). You may want to set approx_sync_max_interval lower than 0.01s to reject spurious bad synchronizations or use approx_sync=false if streams have all the exact same timestamp. When I tmove the ugv and try to take a turn the warnings are denser and the map is like this:  Its like the frames are sliding. I also launch the realsense rs_camera.launch with align_depth:=true Can you help me rectify this? Thank you |
