现在还没有解决呢,之前怀疑是电脑的问题,换了个电脑发现这个问题还是存在

我也遇到了同样的问题,/aft_mapped_to_init话题相对播放的包有半分钟延迟。需要怎么解决一下呀

请问您解决了延迟的问题了吗 |
请问解决了么 我遇到了同样的问题 |
你好~如果是高频(4khz)的里程计输出延迟问题可能是由于ros::spin是一帧雷达进行一次的。如果需要高频非延迟里程计输出,可以修改代码的ros::spin,试试看呢

请问是改rosrate么 我目前Lidar是hap 10HZ |
我想借助point-lio优越的抗振动特性,但是里程计我只需要10HZ的 目前有明显时间延时 |
我发现con_frame打开就可以避免时间延迟,但是里程计会到1HZ。若使用PointCloud2的激光雷达点云可以正常运行,但是使用CustomMsg格式 该情况下程序会死掉 类似bad alloc,vector length这类 |
vector length这些问题大概率是和path publisher里面存储了过多的odometry有关的。

您好,现在我将原来的一些点降采样了,目前没有明显时延了。但是有个疑问,我看pointlio的cpu占用率好像不高,这是为什么,好像只用了两个cpu线程

因为point-lio本质上存在一个串行执行流程,所以后续没有继续做过多线程版本开发

如果想要改多线程的话 比较困难嘛?我不太清楚。想请教一下,主要是哪部分需要改并行多线程呢? |
请问里程计输出延时大约半分钟,这种问题应该怎么解决?
期待您的回答
