scan-to-map匹配是激光雷达中一个基础的概念,scan是当前帧,map是当前帧时空维度上临近的帧组成的集合。map已经经过不断地优化,有一定精度了,而当前帧只有一个初始的估计位姿。至于怎么来的,可以是用前一帧位姿+运动计算,也可以是有外部传感器IMU、轮式里程计等得到的,总之它是不准确的。那么我们可以将当前帧的激...

1:已知上一时刻的地图m,也是未完成的submap。因为scan to map的过程,就是scan to current submap的过程。 2:submap是栅格地图,这是为了方便匹配。 3:机器人在任意时刻,都能看到map上的所有occupied points。但是,scan不一定能扫描到所有的点。 4:matching的过程,实际上就是把scan的所有扫描数据,映射到当前的subm...

So I am thinking that if I can scan it to map[string]interface{} or []map[string]interface{}. So is it possible to do it on GORM? And I also thinking about another thing is when column converted to interface{} what about date? It will be converted to string? (and also for ...

I find out that GORM cast byte arrays to strings, ifColumnTypeScanType elseifbok:=mapValuecolumnRawBytes);ok This behaviour was introduced in 2020 and actually it's not clear why it do so. I thing it's logical that if db value is sql.RawBytes, then it should return[]byte, not stri...
