Caption: The image is taken by the spectroscopic stereo camera, Mastcam, at an angle from a vantage point two meter above the Martian ground and therefore gives a slightly distorted image of the size of the stones depending on their location in the image field. The further away you look, the greater the distortion of the size of the stones in the image. The Danish researchers from the Niels Bohr Institute, together with a German collaborator and the camera team built a system that can rectify the image so that sizes are directly comparable.
