Abstract
Visual measurement is widely used in industrial manufacturing and
assembly fields. Due to the fact that the refractive index field of
the measurement environment is inhomogeneous, the transmitted light
for visual measurements will produce errors. To compensate for these
errors, we introduce a binocular camera for visual measurement based
on the reconstruction of a nonuniform refractive index field using the
schlieren method, followed by the reduction of the inverse ray path by
the Runge–Kutta method to compensate for the measurement error
introduced by the nonuniform refractive index field. Finally, the
effectiveness of the method is experimentally verified, with a
reduction in measurement error of about 60% in the built measurement
environment.
