Effect of extracting the center of structured light stripe directly affects the precision and resolutions of 3D coordinate measure. This paper firstly extracted initial centers of the light stripe with the threshold algorithm
secondly
calculated the normal direction at the initial point of the stripe based on image gray grads
finally
accurately gained the energy centers along the normal direction of the stripe. Experiments show that the approach can get full resolution centers
improves the precision of stripe centers
and avoid min density for max curvature surface of the measured object.
