The concept of structured light system has been applied to recommend scanning positions in selective data acquisition process. The complexity is analyzed from the edge images of a single horizontal line of bright light that is projected locally onto the surface on different side views. Each analysis leads to a recommendation for either scanning position or projecting a new line position. However, an inherent error from mapping 3D object onto 2D image may have negative influence on the decision making. This paper, therefore, presents an attempt to deduce 3D geometric information from edge image by applying 2D projective transformations. On each different side views, the two consecutive projected lines on the horizontal plane are used to analyze the layer's complexity.
