摘　　要：本文基于计算机辅助绘制算法提出了壁画线描画图像提取算法,基于F0范数全局平滑处理图像,并通过高频滤波、构建边缘切向流场,以优化改进的FDoG滤波器提取具备一定增强效果的线条图,此算法在局部区域中笔道灰度值比背景灰度值小时,可生成定位精确,且保留壁画既有风格的笔道。基于此算法设计了壁画线描画图像计算机辅助绘制系统,系统基于Surfacepro平台进行开发,利用触摸笔与手彼此交互的模式,保证操作灵活性。测试结果表明,此系统灵活性、实时性、稳定性基本可以满足用户具体需求。Based on the computer-aided rendering algorithm,this paper proposes a line drawing image extraction algorithm for mural painting.The image is smoothed globally based on F0 norm,and the edge tangential flow field is constructed through high-frequency filtering to optimize the improved fdog filter to extract the line image with certain enhancement effect.This algorithm can generate accurate positioning when the gray value of pen trace in local area is smaller than that of background,The style of the mural is preserved.Based on this algorithm,a computer-aided drawing system of mural line drawing image is designed.The system is developed based on the surface Pro platform,using the touch pen and hand interaction mode to ensure the operation flexibility.The test results show that the flexibility,real-time and stability of the system can basically meet the specific needs of users.
