Marker detection displacement

[benjamin-wozniak]

Hi,

I tried to use jasartoolkit5 to detect matrix markers. And I experienced some strange displacement of the detected marker. The displacement gets stronger if the marker is away from the center. I not sure if that is relevant but I used the default camera_params.dat.

One can also see the displacement in the demo simple_image.html (I modified the debugDraw() method so that the detection is rendered on top of the original image):

Any ideas why this is happening?
