Image Matching and Registration System Based on Improved ORB

摘要: 为了解决当前国内市场中多色套印技术在曲面丝网印刷中的精确对准难题，研究提出了一种基于ORB图像匹配算法的多色套印系统，该系统结合了几何约束和RANSAC筛选算法，使传统曲面丝网印刷不再局限于单色制品，满足了市场对高质量、多色印刷日益增长的需求。通过实验验证了系统的有效性，结果表明匹配正确率超过95%，处理速度达26帧/秒，色板套印精度控制在± 0.03毫米以内。这种方法显著提升了复杂多色图案在曲面物体上的印刷质量和精度，具备广泛的应用前景。

Abstract: To address the challenges of precise alignment in multi-color overprinting for curved surface screen printing in the domestic market, this study proposes a multi-color overprinting system based on the ORB image matching algorithm, incorporating geometric constraints and the RANSAC filtering algorithm. This approach extends traditional curved surface screen printing beyond single-color applications, meeting the increasing market demand for high-quality, multi-color printing. Experimental results verify the system’s effectiveness, demonstrating a matching accuracy rate exceeding 95%, a processing speed of 26 frames per second, and an overprinting accuracy within ± 0.03 mm. This method significantly enhances the print quality and precision of complex multi-color patterns on curved objects, with broad application potential.
