- Abstract:
- To realize the high-precision vision measurement for large scale machine parts, a new vision measurement method based on dimension features of sequential partial images is proposed.Instead of mosaicking the partial images, extracting the dimension features of the sequential partial images and deriving the part size according to the relationships between the sequential images is a novel method to realize the high-precision and fast measurement of machine parts.To overcome the corresponding problems arising from the relative rotation between two sequential partial images, a rectifying method based on texture features is put forward to effectively improve the processing speed.Finally, a case study is provided to demonstrate the analysis procedure and the effectiveness of the proposed method.The experiments show that the relative error is less than 0.012% using the sequential image measurement method to gauge large scale straight-edge parts.The measurement precision meets the needs of precise measurement for sheet metal parts.
