A Flexible Online Camera Calibration Using Line Segments

Figure 13

Results of image-based modelling. The green lines are the projections of the four edges of the calibration items by using the recovered camera parameters. The green crosses are the projections of the model points. We can see that the proposed method provides good matches of the projections of the model lines with the observed positions in the images.
