create_rectification_gridcreate_rectification_gridCreateRectificationGridcreate_rectification_gridCreateRectificationGridCreateRectificationGrid generates a checkered pattern with NumSquaresNumSquaresNumSquaresNumSquaresNumSquaresnumSquares x NumSquaresNumSquaresNumSquaresNumSquaresNumSquaresnumSquares alternating black and white squares. This pattern is WidthWidthWidthWidthWidthwidth meters wide (and high). Around the pattern there is an inner frame of 0.3 times the width of one square, which continues the checkered pattern. The pattern is completed by a solid white outer frame of 0.7 times the width of one square. In the center of the pattern there are two circular marks, one black on a white square and one white on a black square. The radius of both marks correspond to one third of the side length of the respective enclosing square. These marks are used by gen_grid_rectification_mapgen_grid_rectification_mapGenGridRectificationMapgen_grid_rectification_mapGenGridRectificationMapGenGridRectificationMap to rotate the detected layout of the grid points into the correct orientation. It is assumed that the black mark is positioned to the left of the white mark, when oriented correctly. The file GridFileGridFileGridFileGridFileGridFilegridFile contains the PostScript description of the rectification grid.
