获取激光数据时出现 RViz 段错误
[英]RViz seg fault when getting laser data
问题描述
I'm using a ubuntu 20.04 laptop for a robotics class and things have been working pretty well so far.
我正在为机器人 class 使用 ubuntu 20.04 笔记本电脑，到目前为止一切正常。 But after weeks of everything being fine, it stopped working.但在一切正常几周后，它停止了工作。
What happens is I'm starting roscore on my machine or I'm connecting to a robot running roscore, I start Rviz, if I'm using roscore then I'm loading a rosbag with the data I need to work on.发生的情况是我在我的机器上启动 roscore，或者我正在连接到运行 roscore 的机器人，我启动 Rviz，如果我使用的是 roscore，那么我正在加载一个带有我需要处理的数据的 rosbag。 In roscore, I add laser, set the topic as usual and as soon as I put the global topic on /scan it crashes.在 roscore 中，我添加了激光，像往常一样设置主题，一旦我将全局主题放在 /scan 上，它就会崩溃。 No error message except for seg fault.除了段错误之外没有错误消息。
This is what I get on startup:这是我在启动时得到的：
$ rviz
[ INFO] [1619702399.028615354]: rviz version 1.14.5
[ INFO] [1619702399.028654732]: compiled against Qt version 5.12.8

[ INFO] [1619702399.211422253]: OpenGl version: 4,6 (GLSL 4,6)
And on the ubuntu crash report, I have rviz crashed with SIGSEGV .在 ubuntu 崩溃报告中，我让rviz crashed with SIGSEGV 。 I can't seem to fine a workaround online.我似乎无法在网上找到解决方法。 Any help is appreciated!任何帮助表示赞赏！ Thanks!谢谢！
