为什么运行 kalibra_apriltag.launch生成不了txt文件,程序在视频播完卡住了 #29
Comments
我也出现了这个问题 |
请问解决了吗? |
@@tygrer @Russell-fan 请问你们后来解决了吗?我第一次用这个工具,所录的数据和示例所用数据差不多,现象和你的这个一样:红绿蓝的坐标轴显示错误、卡顿(区域2)。我运行roslaunch lasercamcal_ros kalibra_apriltag.launch 时候显示区域1。与你不同的是,我有生成一个apriltag_pose.txt(区域3),但里面有好多组的值是-nan和正无穷大(区域2)。 生成apriltag_pose.txt之后,我又运行roslaunch lasercamcal_ros calibra_offline.launch,如下图区域1所示。其结果显示所有的激光点都是再标定板平面上的点!?而实际上,标定板平面上的点之后区域2中的那个小圈。 所以请教下 @HeYijia 几个问题: @tygrer @Russell-fan @HeYijia 我发现之前的错误现象(红绿蓝的坐标轴显示错误、卡顿)是因为我数据错误的问题(话题没有时间戳、相机内参标注错误)。目前通过运行roslaunch lasercamcal_ros kalibra_apriltag.launch可得到一个apriltag_pose.txt,但是roslaunch lasercamcal_ros calibra_offline.launch的时候,找不到标定板上的激光点(所有激光点都是蓝色的) |
you should make sure that the "savePath" in the "calibra_config" is the right path, eg. "/home/user/LaserCameraCal_ws/src/log/" , you should create the "/log" folder first |
