Hi,all: when I read ImuInitialize ,I found a issue in EdgeInertialGS Jacobians calculate , please hellp me make a check ,thanks! 捕获

I think maybe the result should look like this 微信图片_20220224215249

It also confused me.

@Lagrange1027 请教您一下: 后来的推导,增量为什么要乘以旋转矩阵呢?

I think the jacobian w.r.t the translation of Pose 2 is not exactly the $\bar{p}_i$ in the paper. It should be $p_i$ where $p_i=R^T_i * \bar{p}_j$ here. And that's what it is in the code.

I think the question is good, and code could be wrong.
