A new method of digital image processing technique of digital image acquisition and computer image acquisition is introduced. The model of non-contact measurement is given. By using this model, the welding shrinkage deformation can be measured automatically. This method has been well applied in the measurement of welding shrinkage deformation of a large hydropower station. The application of this method can improve work efficiency
