Abstract
With the development of industrial manufacturing towards higher precision and efficiency, traditional measurement methods are increasingly unable to meet the demands of precise inspection for complex parts. Machine vision-based measurement technology has garnered significant attention due to its non-contact, efficient, and automated advantages. This study aims to explore a precision measurement method that integrates machine vision with error compensation techniques to enhance measurement accuracy and reliability. Initially, a machine vision measurement system based on multi-camera collaboration was constructed, and by optimizing calibration algorithms and image processing technologies, high-precision 3D reconstruction of parts with complex geometric features was achieved. Subsequently, an adaptive error compensation model was proposed to address deviations caused by inherent system errors and environmental factors. This model combines neural network prediction with Kalman filtering algorithms, enabling dynamic adjustment of measurement results and significantly reducing system errors. Experimental results indicate that the proposed measurement and compensation scheme demonstrates excellent stability and accuracy under various working conditions, with a measurement precision improvement of approximately 30% compared to traditional methods. Furthermore, an integrated software platform was developed in this study to facilitate operation and maintenance in practical engineering applications. Overall, this research not only provides a new technical approach for the field of precision measurement but also lays an important foundation for quality control of complex parts and smart manufacturing. Its innovation lies in the effective combination of visual measurement and intelligent compensation, successfully addressing the issue of insufficient accuracy in traditional methods and exhibiting substantial theoretical value and application potential.
