UI里显示程序跑起来了吗?

跑起来了,并且显示的还是对的,我主要添加了如下代码,感觉并没有太大问题,添加了 这些代码后运行起来很慢,可能是我写入频率太高了?:

你应该在程序开始运行时打开一个文件,每次往里写入一行。而不是在每个循环中重新打开这个文件然后追加内容。
写入的程序看上去没什么问题,你可以换种实现方式再试试,或者用glog打印一下。

好的,已经做了如下的修改,但是发现还是挺慢的,其次我将/novatel_data/inspvax的位姿信息导出为东北天坐标系下的轨迹作为真值,把评测的轨迹导出作为估计值,发现它们轨迹z轴接近90度偏差,之前在用组合导航做真值时好像也遇到了这个问题,有点不解这是什么导致的?

我不太确定这个数据集中的RTK是什么坐标系,角度是东北天还是北东地,另外它是否有安装外参,这些得去查数据集对应的网站或者论文。
所以处理各数据集真值是一件相当枯燥而且容易踩坑的事情。。。

我直接自己手动旋转 90度了,感觉可能是安装参数有个90度:
result_map

但是我又碰到了gflag的bug,参数无法设置,于是我把所有参数在程序开始时打印出来,结果确实没有设置成功。

@gongjun136
gflags的 bool 类型需要写成 --display_map=false 的形式,不能中间带空格。
我也不知道为啥。。可能gflags就得这么用
