Recently
the chaps here at EuroPac 3D were asked if they would scan a company
logo. The image was printed on a piece of paper and therefore was just
a flat logo with no depth or texture.• The solution was to use the powerful exposure compensation of the Perceptron laser scanner which was set in order that colour could be detected against the white background paper it was printed on. The result was superb the laser collected a point cloud purely where the coloured logo was found while not collecting any points on the surrounding white paper.
• The point cloud was then converted into a triangulated surface mesh from which this profile could be extruded by a distance to create a model with depth. The conclusion is a 2D logo had been converted into a 3D model in a matter of minutes.
• The resultant 3D mesh file (STL) was then given to a rapid prototyping company and laser engraved in miniature size for the purpose of being encased in a crystal award.
