Valid Calibra Data Less

[DeepDuke]

Hi, 我标定时执行roslaunch lasercamecal_ros calibra_offline.launch 后，没几秒就结束了，打印出的消息有 Load apriltag pose size 46 和 Valid Calibra Data Less 请问是有效的数据点太少导致的嘛？我用的标定板是A4的，是不是因为标定板太小了？

我重新采集了数据，没有Valid Calibra Data Less的错误了，但是报了这个错

似乎是vector有溢出？

[HeYijia]

激光标定板有被正确识别吗？

[DeepDuke]

有的，被识别出来了

你好，请问这个问题解决了吗，我也遇到这个问题Valid Calibra Data Less

[DeepDuke]

@NCH550 多采点有效数据点就好了

@DeepDuke @HeYijia

你好，我使用A4（tag_size=0.021m，tag_space=0.006m）和大的标定板（tag_size=0.088m，tag_space=0.0264m）录制的数据包在标定的时候都会报错：Valid Calibra Data Less，录制的数据在2-3min左右，标定板也有被正确识别，这是我数据采集的不好吗：
