安装:Installation — COLMAP 3.9-dev documentation
使用:Tutorial — COLMAP 3.9-dev documentation
下载一个小猫的RGB数据集 THU-MVS: Multi-View 3D Reconstruction Datasets
创建 project_cat
文件夹,把图片放 project_cat/images
下
运行 COLMAP.bat
启动程序,官方文档中有一些实用的操作说明:Graphical User Interface — COLMAP 3.9-dev
documentation
Rotate model: Left-click and drag.
Shift model: Right-click or -click (-click) and drag.
Zoom model: Scroll.
Change point size: -scroll (-scroll).
Change camera size: -scroll. (红色的表示相机拍摄位置的符号)
Adjust clipping plane: -scroll. (距离观察视点一定距离的点会被 clipped)
Select point: Double-left-click point (change point size if too small). The green lines visualize the projections into the images that see the point. The opening window shows the projected locations of the point in all images.
Select camera: Double-left-click camera (change camera size if too small). The purple lines visualize images that see at least one common point with the selected image. The opening window shows a few statistics of the image.
Reset view: To reset all viewing settings, choose Render > Reset view.
执行 Automatic reconstruction 进行一次
需要等待比较久的时间,最开始比较占用CPU,大概执行的是特征点计算和匹配一类的,后面会占用比较大的GPU使用率,GPU内存占用大概2G.
到下面的界面后表明完成。
同时介绍了可视化sparse, dense, mesh 模型结果的方法。

稀疏重建
稠密重建
凑近看是稠密点云
