Method of improving surface stripe light reconstruction precision

The invention discloses a method of improving surface stripe light reconstruction precision, which comprises the following steps: (1) a stripe pattern of stripe light on a workpiece and a white pattern of white light on the workpiece are acquired respectively through stripe light and white light; and (2) through observing the difference of intensities of the stripe light on a glass table and on the tested workpiece, a threshold is set, the white pattern is processed, and the position of the workpiece is positioned through the white pattern. As the intensities of the stripe light on the glass table and on the tested object are observed to be different, a reasonable threshold can be found out to process the pattern, the influences of the stripe light trace on the glass stage can be eliminated, the three-dimensional reconstruction effects for an object placed on the transparent stage can be well improved, the pattern of white light on the object is used to position the object, the patternis used as a mask to cov
