基于SIFT-ACO的图像拼接算法

针对具有一定旋转角度的多幅图像拼接问题，提出了一种基于SIFT-ACO的图像拼接算法。对拼接图像进行预处理后，用SIFT算法提取图像特征，将经典的生物智能优化算法ACO加入到图像配准中，对图像特征点进行配准，最后将多幅图像融合，得到一幅宽视角、无缝、高精度的图像。对多组不同角度拍摄的图像进行拼接试验。试验结果表明：在不影响整体视觉效果的前提下，该算法能有效地提高图像拼接精度。

Image Mosaic Optimization Algorithm Based on SIFT-ACO

For problems of multiple images stitching of certain rotation angle, puts forward an image mosaic optimization algorithm based on SIFT-ACO. After the mosaic image preprocessing, the algorithm uses SIFT algorithm to extract the image features, adds classic intelligent optimization algorithm to image registration and makes image feature points registration, at last fuses multiple images and obtains a wide viewing angle, seamless and high precision image. The experimental result of image mosaic of different angles indicates that the algorithm can improve the accuracy of image matching effectively without affecting the overall visual effect.
