velodyne 一般的数据格式为.pcap,现在的需求是将.pcap转为rosbag,并且rosbag的header->stamp要是.pcap的采集时刻。网上能找到的做法通常是用velodyne_driver+pcap_time:=true+gps_time:=true、velodyne_pointcloud、rosbag record 进行处理。但此种方法记录下来的rosbag,其header->stamp已变成了此时电脑unix time。...

rosbag录制完成后ctrl+C结束,会在rosbag record窗口路径下,生成.bag文件。 七、rosbag play image+imu 由于android应用slam程序保存image和imu的时间戳,是从手机最近一次开机开始算起,当然也可以自己换算成1970年开始,但是目前好像还没那个需求,所以在image和imu发布时,利用上述"TimestampToRosTime"函数转换时间戳后...
with open("timestamps.txt",'w') as f: for idx, t in timestamps: f.write('{0},{1},{2}\n'.format(str(idx).zfill(8), t.secs, t.nsecs)) So as you can see I open the bag and get a list of timestamps and record it in a text file. Which gives: ...
record用指定主题的内容记录一个包文件。 reindex重新索引一个或多个包文件。 与例子无关的题外话 回放数据包时,如果想用 Rviz 可视化数据,可能会遇到时间不匹配的问题,出现如下错误信息: ... Message removed because it is too old (frame=..., stamp=...) ...
<node pkg="rosbag"type="record"name="bag_record"args="/topic1 /topic2"/> 默认存放路径是 ~/.ros 中。 上边命令开启了数据记录,然后回到turtle_teleop节点所在的终端窗口,控制 turtle 随处移动10秒钟左右。 在运行rosbag record命令的窗口中按Ctrl-C退出该命令,即结束数据记录。
Otherwise, the "-o" is also an interesting option (seerosbag record), as it permits to append the timestamp to the filename. So if you record twice the same thing, it won't be overwritten ;-) [EDIT] (please edit your question instead of putting a comment) as said in the h...
