Research on image recognition method for misalignment of gates in large ship locks

摘要

探讨了基于图像识别技术的某大型船闸人字闸门门缝错位检测方案。采用高清晰度图像采集设备，并通过对采集到的图像进行预处理、特征提取和支持向量机分类器训练等步骤，实现对人字闸门门缝、错位的实时检测。通过现场样机测试和误差分析，证明该方案具有实用性和良好的检测效果，满足该船闸的实际应用要求。

Abstract

The misalignment detection scheme for the miter gate of a large ship lock using image recognition technology was discussed. High-definition image acquisition equipment was used. Real-time detection of gaps and dislocations in the miter gate was achieved through pre-processing, feature extraction, and SVM classifier training. Field prototype testing and error analysis have demonstrated the practicality and effectiveness of the scheme, meeting the practical application requirements of ship locks.
