Question about triangulateLinear #37

Closed fushi219 closed 1 year ago

Hi! I'm confused about the jacobian below, it seems that the term "S0inv Q S0inv" is the jacobian of S0inv to normalized v(vn), but how it is derivate? Thanks a lot! https://github.com/SpectacularAI/HybVIO/blob/main/src/odometry/triangulation.cpp#L879
