Abstract

Objective:The three-dimensional reconstruction method based on vision uses the digital camera as the image sensor. Establishing the model of a dynamic measured object is the premise of the vision precise measuring system. Methods: By using the pinhole camera model and the mathematical modeling method, the three-dimensional reconstruction of the measured part can be completed quickly based on the known measured objects. The corresponding relation can be realized accurately and automatically on condition that the object's shape characteristic is known clearly. The algorithm of the three-dimensional measuring model of cylindrical workpiece can be established conveniently. Results: The algorithms are verified by simulation with Solidworks and Matlab. The correctness of the algorithm is validated by actual experiment and the absolute error is less than 0.015mm or the relative error is less than 0.1%. Conclusion: The measuring results are accurate enough to satisfy the practical requirement of fast and precise measuring in industrial field.
