A gyroscope-based system and method is disclosed. Image information data is collected; a mechanical arm working environment image is modeled; a heat source supply apparatus and a gyroscope are provided at the mechanical arm proximal end; the position of the proximal end is accurately measured by accurately tracking the heat source at the proximal end; the relative position of the mechanical arm distal end is accurately calculated by using high-precision angle information measured by the high-precision gyroscope in combination with a number-theoretic formula. The disclosure provides separately determining the position of the distal end, or for assisting other algorithms or apparatuses that track the position of the mechanical arm distal end in error correction and calibration of the position of the mechanical arm distal end. The position of the mechanical arm distal end can be continuously and dynamically tracked in real time, and virtualized in the corresponding image system.
