An optical inspection system comprises: an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet (G), wherein the planar laser sheet intersects a surface of the glass sheet (G) thereby causing the surface of the glass sheet (G) to fluoresce and form a visible wavelength line on the surface; a first camera having a first image sensor for detecting the visible wavelength line across a first portion of a width of the glass sheet (G); a second camera having a second image sensor for detecting the visible wavelength line across a second portion of a width of the glass sheet (G) separate from the first portion such that the first camera and the second camera have overlapping and separate fields of view on the surface of the glass sheet (G); and a control system configured to (i) receive image data indicative of the visible wavelength line from the first camera , (ii) analyze the data from the first camera to determine first and second coordinates in a first series of coordinates associated with the line, (iii) triangulate a third coordinate associated with each of the first and second coordinates in the first series of coordinates, (iv) create a first three-dimensional map (M1) of the surface of the glass sheet (G) as a function of the first series of coordinates, (v) receive image data indicative of the visible wavelength line from the second camera, (vi) analyze the data from the second camera to determine first and second coordinates in a second series of coordinates associated with the line, (vii) triangulate a third coordinate associated with each of the first and second coordinates in the second series of coordinates, (viii) create a second three-dimensional map (M2) of the surface of the glass sheet (G) as a function of the second series of coordinates, and (ix) form a combined map (M3) using the first map (M1) and the second map (M2). an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet (G), wherein the planar laser sheet intersects a surface of the glass sheet (G) thereby causing the surface of the glass sheet (G) to fluoresce and form a visible wavelength line on the surface; a first camera having a first image sensor for detecting the visible wavelength line across a first portion of a width of the glass sheet (G); a second camera having a second image sensor for detecting the visible wavelength line across a second portion of a width of the glass sheet (G) separate from the first portion such that the first camera and the second camera have overlapping and separate fields of view on the surface of the glass sheet (G); and a control system configured to (i) receive image data indicative of the visible wavelength line from the first camera , (ii) analyze the data from the first camera to determine first and second coordinates in a first series of coordinates associated with the line, (iii) triangulate a third coordinate associated with each of the first and second coordinates in the first series of coordinates, (iv) create a first three-dimensional map (M1) of the surface of the glass sheet (G) as a function of the first series of coordinates, (v) receive image data indicative of the visible wavelength line from the second camera, (vi) analyze the data from the second camera to determine first and second coordinates in a second series of coordinates associated with the line, (vii) triangulate a third coordinate associated with each of the first and second coordinates in the second series of coordinates, (viii) create a second three-dimensional map (M2) of the surface of the glass sheet (G) as a function of the second series of coordinates, and (ix) form a combined map (M3) using the first map (M1) and the second map (M2). <EOS>
