Abstract
In the 3D measurement based on line-structured light projection, the accuracy of center position of the stripe is of great importance for that of the 3D information acquisition system. A method of sub-pixel center-extracted that in the level of sub-pixel were discussed by He Jun-ji. Based on it and considered the fact that light intensity of the stripes center presents a Gaussian distribution status approximately, in this paper, a new method for extracting stripe center line has been proposed. The extracting curve is closer to the ideal value, and can efficiently extracted the center-line of light stripe, and the accuracy of 3D reconstruction is improved.
