The next step is to align and process the images into a high-quality 3D mesh and point cloud which you can share with your organization and clients as an integrated mesh scene layer and point cloud scene layer. If you have already captured aerial imagery at city or country scale, use ...
point cloud:不规则数据结构。即如字面意思,用一堆的点来表示物体; mesh:不规则数据结构。由点、边、面组成。 根据各种不同的表示方法我们可以知道volume受到分辨率和表达能力的限制,会缺乏很多细节;point cloud,点之间没有连接关系,会缺乏物体的表面信息。相比较而言mesh的表示方法具有轻量、形状细节丰富的特点。
用 Point·E 依据文本提示生成 3D 点云的过程分为三个步骤：1、依据文本提示，生成一个合成视图 (synthetic view)2、依据合成视图，生成 coarse point cloud (1024 point)3、基于低分辨率点云和合成视图，生成 fine point cloud (4096 Point)Point·E 流程概览 由于数据格式和数据质量对训练结果影响巨大，Point·...
