The invention belongs to the technical field of molecular imaging, and discloses a fluorescent molecular tomography rapid reconstruction method, system and device and a storage medium, a specific fluorescent probe is excited by an excitation light source, and biological tissue surface light distribution information is obtained by using a data acquisition system; constructing a linear relation between surface light source distribution and a fluorescent target based on a light transmission model and a finite element method; converting the obtained linear relation into an optimization problem to be solved; and quickly solving the optimization problem by using a self-adaptive quick iterative shrinkage threshold algorithm, and displaying a result to finish reconstruction. According to the method, multi-point excitation and multi-angle measurement are adopted, a linear relation between measurement data and a fluorescent target is established in combination with a light transmission model and a finite element method
