The principles of the method of differentiation and curve fitting for measuring industrial size with TV camera are briefly described in this paper. The accuracy limitation of these two methods are discussed in detail. The calculated theoritical results are proved experimentally. How to measure two dimensional objects according to its shape and position as well as the properties of optical systems, this paper finally proposed some points for object localization and mentioned processing method for testing the corner of the object.
