The Missing Link: Calibrating a Sparse RGB Rig with OptiTrack

It has been a long time since I last wrote a blog post. Honestly, I almost stopped. In the age of LLMs, writing about technical topics feels pointless — whatever you want to know, an AI will explain it more clearly and faster than any blog. So why bother? What changed my mind was running into a problem where AI could tell me the theory perfectly well but couldn’t tell me what actually went wrong when I tried it. That gap only gets filled by doing it: wiring two physical sensor systems together, watching them disagree, and working out why. That kind of experience doesn’t live in training data yet. Physical AI is full of it.
