三维书籍模型的单侧页面提取方法

摘要

针对目前点云分割方法较难分割三维书籍模型的情况,提出一种快速有效的单侧书籍页面的自动提取方法.对于获取的三维书籍模型,利用模型的点云深度信息,求出背景平面方程,去掉模型背景,保留书籍区域;通过分析书籍模型的形态特性,求出分割左右页面的空间平面,保留其中一侧页面;根据点云的密度分布去掉页面的书口区域点云,得到单侧页面的三维模型.实验结果表明,该方法能够快速稳定地提取出单侧页面,具有较高的准确性和速度性能.%Aiming at the condition that using the current point cloud segmentation method is comparatively difficult to segment the three-dimensional book model,a quick and efficient automatic extraction method for single side book page was presented.For the three-dimensional books model acquired,using the point cloud depth information,the background plane equation was worked out and the model background was deleted to keep the books area.By analyzing the shape features of the model books,the space plane to segment two side pages was determined to keep one side page.The point cloud of book fore-edge was removed based on the point cloud density distribution,eventually getting the three-dimensional model of the single-side page.Experiment results show that this algorithm can extract the single side page fast and stably and achieve good accuracy and high-speed performance.
