摘要
在激光扫描点云数据色彩交互界面的设计中,存在三维模型仿真度偏低的问题,设计一种面向激光扫描点云图像色彩界面的交互设计平台。平台由点云图像预处理模块、三维建模与模型渲染模块、色彩差异修正模块、界面交互设计模块构成。点云图像预处理模块通过弦高差法实现有序点云图像数据的降噪处理,通过双边滤波方法实现散乱点云图像数据的降噪处理。三维建模与模型渲染模块能够实现物体三维模型的构建、纹理映射、渲染。在色彩差异修正模块中,通过色彩迁移算法实现模型的色彩差异修正。在界面交互设计模块中,将界面设计分为三个内容模式的设计:互动、比较、展示。测试设计平台与三种对比方法,测试结果表明设计平台古建筑的三维模型仿真度为99.51%,现代复杂建筑的仿真度为99.78%;交互场景真实度高于97%。
In the design of color interaction interface of laser scanning point cloud data,there is a problem of low simulation degree of 3D model,so an interaction design platform for laser scanning point cloud image color interface is designed.The platform consists of a point cloud image preprocessing module,a 3D modeling and model rendering module,a color difference correction module,and an interface interaction design module.The point cloud image preprocessing module realizes the noise reduction processing of the ordered point cloud image data through the chord height difference method,and realizes the noise reduction processing of the scattered point cloud image data through the bilateral filtering method.The 3D modeling and model rendering module can realize the construction,texture mapping and rendering of 3D models of objects.In the color difference correction module,the color difference correction of the model is realized through the color migration algorithm.In the interface interaction design module,the interface design is divided into the design of three content modes:interaction,comparison,and display.Test the design platform and three comparison methods.The test results show that the simulation degree of the 3D model of the ancient building of the design platform is 99.51%,the simulation degree of the modern complex building is 99.78%,and the authenticity of the interactive scene is higher than 97%.
