Wait for imu data
shenglunch opened this issue · 10 comments
Hello Gao，
May I ask you a question？After run launch file，“wait for imu data” will appear. I check topic information(rostopic list & rostopic inof /xx), there is not any problem.
Thank you very much！
you need to wait for the bad file playing end,,look at the imu_an.cpp.

thanks!
@csl1994 hay~ i also have same problem as you did. do you solved the problem ? @johnjin404 i already your suggest try to wait for bag file playing until the end but nothing change. is it need to do it at the same time ? (playing bag file and do roslaunch) or play the bag file before do roslaunch ? both of them i already try it but still the same. if you have any idea ill be really grateful.

@maxwu8416 I think the parameter("max_time_min") means that the bag file should be played for xxx minutes, so I changed it to 1 minute and it will be finished soon, but it will remind me that "the time is too short".finally i run imu for 40 m, and set the parameter as follow
<param name="max_time_min" type="int" value= "30"/>
Okay~ seems worth to try ! Thx for ur reply ! I’ll try it later and update the info
It seems that the program doesn't give useful feedback about whether it receives imu info. But it does. So if you cannot be sure, just change max_time_min in your launch file to 1 min or so, and see the results. But for accurate results you have to at least run it for about 2 hours.
Hi, I am facing the same problem here. How am I going to configure the duration of the data recording? I recorded a rosbag for 1 minute. I did make some changes in the launch file & imu_an.cpp.
But the recording is still too short. Where and how should I change the parameters? FYI, I am still new in cpp.
Thank you so much for your help!
@maxwu8416我认为参数(“max_time_min”)的意思是bag文件要播放xxx分钟，所以我把它改成1分钟，很快就播放完了，但它会提醒我“时间太短”。最后我运行imu 40 m，参数设置如下
<param name="max_time_min" type="int" value= "30"/>
THINKS! IT HELPFUL!
