I’m writing my master’s thesis. I’m beginner user of ROS. I use Husarion ROSbot 2.0 (ROS Melodic). I’m trying to run leg_detector (http://wiki.ros.org/leg_detector) on this device. I want to tracking people using LiDAR. I cloned repository (GitHub - wg-perception/people) to my workspace. I added node of LiDAR to launch file (leg_detector.launch). I changed arg scan from scan:=base_scan to scan:=/scan.
include file=“$(find rplidar_ros)/launch/rplidar.launch”
After the command: roslaunch leg_detector leg_detector.launch, I see following, cyclic error messages in terminal:
[ WARN] [1657705125.709984398]: MessageFilter [target=odom_combined ]: Dropped 100.00% of messages so far. Please turn the [ros.leg_detector.message_filter] rosconsole logger to DEBUG for more information.
[ WARN] [1657707032.581360628]: Transform from imu_link to base_link was unavailable for the time requested. Using latest instead.
rqt_graph looks good, but at graph’s end is not topic with position of people. After command roslaunch people_velocity_tracker tracked_detector.launch, I see relevant topic, but first error message too. Topic is empty.
What am I doing wrong? I would really appreciate if anybody helps me.
I added mentioned line (exactly) to launch file. I changed .yaml file.
Now I get following error messages:
[ERROR] [1658736936.585785340]: Odometry message frame_id was odom, expected map or odom_combined
[ WARN] [1658736936.633071226]: MessageFilter [target=odom_combined ]: Dropped 100.00% of messages so far. Please turn the [ros.leg_detector.message_filter] rosconsole logger to DEBUG for more information.
