Abstract: A first set of pixels forming a first set of rows and a first set of columns of a first image acquired by an image acquisition device is received. A first corrected set of pixels forming a first corrected set of rows and a first corrected set of columns is generated from the first set of pixels. Successive pixels of each row from the first corrected set of rows correspond to successive parallel lines in a plane defined by the sheet of light that are equally spaced along a first axis of a world coordinate system. Successive pixels of each column from the first corrected set of columns correspond to successive parallel lines in the plane defined by the sheet of light that are equally spaced along a second axis of the world coordinate system. Based on the first corrected set of pixels, a first set of points of the sheet of light is determined. The first set of points of the sheet of light is used to obtain a three-dimensional profile of the object.

Abstract: A first set of pixels forming a first set of rows of a first image acquired by an image acquisition device is received. A first partially corrected set of pixels forming a first partially corrected set of rows is generated from the first set of pixels where successive pixels of a row from the first partially corrected set of rows correspond to successive parallel lines in a plane defined by the sheet of light that are equally spaced along a first axis of a world coordinate system. Based on the first partially corrected set of pixels and based on a peak extraction mechanism, a first partially corrected set of points of the sheet of light is extracted. The first partially corrected set of points is transformed to obtain a first corrected set of points of the sheet of light that are corrected in a first and a second direction.
