以制作全景图为例将图像拼接技术应用到制作动漫贴图上,简化动漫贴图的制作.使用手持相机采集一定重叠区域的图像,柱面投影后采用基于尺度空间的Harris算法检测图像特征点,双向归一化互相关算法匹配特征点,迭代提取阈值T的算法去除误匹配.通过改进的RANSAC算法快速估算出变换参数模型,对拼接图像进行投影变换.Szeliski灰度融合方法,直接计算匹配点灰度平均值融合图像,最后采用最佳缝合线的方法消除图像拼接处的重影.基于Matlab的数据实验表明,提出的图像拼接技术具有效率高,拼接图像清晰等优点,实现了较满意的全景图视觉效果.
Application of Image Mosaic Based on Feature Point in the Animation
To simplify the steps of the animation production,the image mosaic technology is applied to the animation production with panorama as an example,and some images of the overlapping area with the cemera were collected.After the cylindrical projection,the Harris algorithm was used to detect the feature points of the images in the scale space.And the double direction of normalized cross correlation in feature-point matching was adopted.The threshold T was extracted repeatly to remove the mismatch feature points.And the project model was estimated with the improved RANSAC algorithm.A method of gray adusting to image fusion,and the beat seam-line is introduced to eliminate image ghosting.The data experiments based on Matlab showed that the image mosaic technology could effectively mosaic image and achieve a satisfactory visual panorama.
