摘要
随着倾斜摄影实景三维应用的逐步普及,实景三维技术已广泛应用到各行业数字化应用场景中,但是海量实景三维数据会导致应用端网络访问效率下降、系统内存溢出、场景渲染延迟等问题,严重制约了实景三维应用扩展。为更好提升倾斜摄影实景三维成果的应用效率,让实景三维成果同时适合在PC端、Web端、移动端兼容访问与顺畅浏览,需要对倾斜摄影实景三维数据成果进行优化处理,在不损失精度与预览效果的前提下,针对不同数据情况选取不同的优化手段,探索一套优化的数据处理与优化方法,进一步降低数据冗余、压缩模型纹理、优化模型结构,制定最优数据成果发布模式,提高网络访问效率,让海量实景三维数据成果能够达到最佳访问效果。
With the gradual popularization of the real scene 3D application of tilt photography,the real scene 3D technology has been widely used in the digital application scenes of various industries.However,the massive real scene 3D data will lead to the problems such as the decline of the application end network access efficiency,system memory overflow,scene rendering delay and so on,which seriously restricts the expansion of the real scene 3D application.In order to better improve the application efficiency of tilt photography real scene 3D results and make the real scene 3D results suitable for compatible access and smooth browsing on PC,web and mobile terminals at the same time,it is necessary to optimize the tilt photography real scene 3D data results,and select different optimization methods for different data conditions without losing accuracy and preview effect.Explore a set of optimized data processing and optimization methods,further reduce data redundancy,compress model texture,optimize model structure,formulate the optimal data achievement release mode,improve network access efficiency,and make the massive real scene 3D data achievements achieve the best access effect.
