Elimination of Accumulated Error of 3D Target Location Based on Dual-View Reconstruction
3D target location from long image sequence with a single hand-held camera based on dual-view reconstruction is an important method in practice, but accumulated error is unvoidable and can not be ignored in the process of seveal dual-view reconstruction especially the length of squences is long. The paper studied the principle of dual-view reconstruction of long image sequences and the cause of accumulated error. An improved method of 3D target location using truncated squcences to eliminate accumulated error is put forward. An four-element method of rigid body transformation is also presented in this method to solve absolute orientation. Simulated experiments as well as real image tests show that the new method gives an accurate and robust result even in the high-level noise situation. It can be applied to measuring large object, key points registration, interference checking in some assembly scenarios and CAD model, etc.
