WebDLT = K*m*P # or DLT = K*m*P*eRT if one of the cameras is located at the origin This should give you a 3 row, 4 column array. Normalize the result by dividing by the final value nDLT = DLT/DLT (3,4) # 3rd row, 4th column The first 11 values of nDLT are now the 11 DLT coefficients, hooray! WebThe trick of the DLT (Direct Linear Transform) is to express eq. 1 (non linear in 7 independent parameters) into an equation linear in the following 11 parameter that, on …
