Abstract: I will present a linear solution for reconstructing the 3D trajectory of a moving point from its correspondence in a collection of 2D perspective images, given the 3D spatial pose and time of capture of the cameras that produced each image. Triangulation-based solutions do not apply, as multiple views of the point may not exist at each instant in time. A geometric analysis of the problem will be presented and a criterion, called reconstructibility, will be defined to precisely characterize the cases when reconstruction is possible, and how accurate it can be.
