Measuring floorplan: an image analysis example
As a suggestion from one of our users, we used Pixcavator to analyze floorplans. The task is very simple – measure the rooms.
Measuring irregular (or even regular) isn’t easy for a person because unless all rooms are rectangular one needs know some geometry. If the corners aren’t 90 degrees, you may have to measure them and then (OMG!) use trigonometry. The walls can also be curved. If the curves are known, all you need is calculus (OMG!!). It is unlikely that the formulas for the curves come with the floorplan, so digital image analysis seems inevitable.
The results are below. Of course, I had to “close” the doors first.
Calbration wasn’t addressed though.
