Abstract: Based
on the theory of perspective projection and the theory of spatial
analytic geometry a new modeling method of laser auto-collimation angle
measurement is proposed. Through analyzing on the center of ellipse
track of spot and reference zero of system, a mathematical model of this
distortion error of the reference zero is established. Meanwhile, the
simulation is done and some conclusions about the distortion error are
drawn. An available theoretical reference for the system calibration of
laser auto-collimation angle measurement or the obtainment of the
reference zero is proved. Thus it is really significant in theory and is
valuable in engineering applications.
