【Abstract】 Three-dimensional measurement of the size of a moving hot steel slab using an area-array CCD camera is proposed.The mathematical model for the measuring system is developed.The relationship between the system error and structural parameter is analyzed. The range of the best magnitudes of the look-down angle θ is found.更多还原
