makegrid.m

一个很好用的摄像机标定程序

function Spoints = makeGrid( sizeX, sizeY, stepX, stepY )
%
% Spoints = function makeGrid( sizeX, sizeY, stepX, stepY )
%
% creates the calibration grid
%
% sizeX - number of columns
% sizeY - number of rows
% stepX - distance between columns
% stepY - distance between rows

for i = 1:sizeX
	k = 0;
	for j = 1:sizeY
		Spoints((i-1)*sizeY + j, 2) = (i-1)*stepX;
		Spoints((i-1)*sizeY + j, 1) = k;
		k = k + stepY;
	end;  
end;
