The cluster that contains most correspondences after this 
iterative testing procedure is selected. This cluster contains 22 
correspondences and is visualized in Figure 5 (bottom) and 
Figure 6. The overall test is rejected, although individual 
correspondence tests are all accepted. This is probably mainly 
due to the presence of some structure in the façade that violates 
the coplanarity assumption of the object points and lines. 
Figure 5: Top: results of line extraction and vanishing point detection of images 6 (left) and 3 (right). Middle: points from line 
intersections. Bottom: result of correct correspondence detection. 
Figure 6 shows the position of the two images relative to the 
façade and the reconstructed part of the façade. This 
reconstruction results from creating a bounding box around the 
detected points of the façade. Their 3D coordinates are 
computed through forward intersection.
