DUSt3R 三维重建

git地址：

GitHub - naver/dust3r: DUSt3R: Geometric 3D Vision Made Easy

报错RecursionError: maximum recursion depth exceeded in comparison

解决方法：

原版给的python版本是3.11，3.10换成3.11问题消失了。

Warning, cannot find cuda-compiled version of RoPE2D, using a slow pytorch version instead

报错 numpy.core.multiarray failed to import

pip uninstall numpy opencv-python
pip install numpy opencv-python

报错Numpy is not available 解决

File "F:\project\3dgs\dust3r\aaa.py", line 6, in <module> torch.from_numpy(np.array([1,3,5],np.uint8))

RuntimeError: Numpy is not available

解决方法：

pip uninstall numpy

pip install numpy==1.26.0

修改了参数设置脚本：

测试效果

Our new model with a local feature head, metric pointmaps, and a more scalable global alignment!

我们的新模型具有局部特征头、度量点图和更具可扩展性的全局对齐功能

模型2.6G

找了两个图片测试，速度比DUSt3R慢了。

在驾驶场景效果也没看到提升.

操作技巧

浏览器操作，滚轮可以缩放点云的大小，不能缩放可能要换个浏览器。
