Claim:
Method of reducing distortion of an image projected onto a moving object, said method comprising the following steps: i) dividing a movement pattern of said moving object into N discrete position states; ii) for each discrete position state: a) obtaining a light transport matrix T relating a projector to a camera whose field-of-vision includes said moving object; b) for each row in light transport matrix T, comparing matrix entries along a common row of said light transport matrix T, retaining the highest valued matrix entry in the common row and assigning a null value to remaining entries in said common row to create a modified light transport matrix T*; c) identifying, in turn, each column in modified light transport matrix T* as a target column, and for each target column calculating normalized values for non-null values in said target column with reference to said target column; d) creating an intermediate matrix of equal size as said modified light transport matrix T*; e) populating each column in said intermediate matrix with the calculated normalized values of its corresponding target column in said modified light transport matrix T*, each normalized value in each populated column in said intermediate matrix maintaining a one-to-one correspondence with said non-null entry values in its corresponding column in said modified light transport matrix T*; f) applying a transpose matrix operation on said intermediate matrix to create a view projection matrix V CI , and correlating said created view projection matrix to the current discrete position state of said moving object; g) creating a transformed image p I of a desired projection image by multiplying said desired projection image by its corresponding view projection matrix V CI as determined by the moving object's current discrete position state DP_I, said current discrete position state DP_I being the one of said N discrete position states within which said moving object currently resides, said transformed image p I being correlated to its corresponding current discrete position state DP_I; and iii) having said projector project transformed images correlated to the discrete position state within which said moving object currently resides.
