摘　　要：由于进行激光射线成像图像重建的过程中没有对图像去噪处理,导致图像画面模糊,为此提出基于侧影轮廓的激光射线成像图像重建方法。采用两侧相邻法进行直线插补,去除激光射线成像图像中存在的噪声;结合图像灰度二值化方法将去噪后的图像转化成黑白二值图像;通过侧影轮廓中心相位提取二值图像特征;采用包围盒方法,建立图像重建三维数据场,按照数据场对激光射线成像序列实行直接绘制,实现图像重建。通过实验可知,所提方法重建后图像画面清晰,能够全面展现原始图像内纹理细节信息,且图像重建效率较高。Since the image is not denoised in the process of laser ray imaging image reconstruction,resulting in blurred image picture,a laser ray imaging image reconstruction method based on silhouette contour is proposed.The two side adjacent method is used for linear interpolation to remove the noise in the laser ray imaging image;Combined with the image gray binarization method,the denoised image is transformed into a black-and-white binary image;The binary image feature is extracted by the central phase of the silhouette contour;Using the bounding box method,the three-dimensional data field of image reconstruction is established,and the laser ray imaging sequence is directly drawn according to the data field to realize image reconstruction.Experiments show that the image reconstructed by the proposed method is clear,which can comprehensively show the texture details in the original image,and the image reconstruction efficiency is high.
