摘　　要：图像是目前视觉传达领域的关键信息载体之一,由于采集设备、压缩技术、传输环境与显示模式等多种因素的影响,致使视觉传达图像清晰度较差,制约着视觉信息的传达效果,故提出基于激光视觉数据融合的视觉传达图像清晰化处理方法。应用激光雷达与单目相机获取视觉传达对象的相关信息,提取激光数据特征——点云密度、激光数据点法线与激光数据点曲率,视觉数据特征——颜色特征、纹理特征、形状特征与空间关系特征,以此为基础,搭建激光视觉数据融合框架,确定激光数据特征与视觉数据特征融合尺度,将激光数据投影到视觉图像上,从而实现了视觉传达图像的清晰化处理。实验结果显示:应用提出方法获得的视觉传达图像清晰度较高,视觉传达图像信息熵最大值为35 bit,充分证实了提出方法图像清晰化效果更佳。Image is one of the key information carriers in the field of visual communication at present.Due to the influence of many factors such as acquisition equipment,compression technology,transmission environment and display mode,the clarity of visual communication image is poor,which restricts the communication effect of visual information.Therefore,a clear processing method of visual communication image based on laser visual data fusion is proposed.The laser radar and monocular camera are used to obtain the relevant information of the visual communication object,and the laser data features,such as point cloud density,laser data point normals and laser data point curvatures,and visual data features,such as color features,texture features,shape features and spatial relationship features,are extracted.On this basis,a laser vision data fusion framework is established,the fusion scale of laser data features and visual data features is determined,and the laser data is projected onto the visual image,thus realizing the clear processing of the visual communication image.The experimental results show that the visual communication image obtained by the proposed method has high definition,and the maximum information entropy of the visual communication image is 35 bit,which fully proves that the proposed method has better image clarity effect.
