Abstract

Laser ranging is an emerging measurement technology in recent decades. In the short-range distance, phase-shift laser ranging has a wide range of applications. To improve the phase-shift laser ranging measurement accuracy, through analyzing principles and characteristics of phase-shift laser ranging, we proposed a novel method based on the least-square method. Then a theoretical model is established and verified by experiment. Later we compute residual sum of squares of least-square and residual sum of squares of piecewise linear, and make the average rate of residual sum of squares decrease by 22.06797%.
