Noise in depth gt #4
Comments
Sorry for the late reply. Have you tried depth from other view? Did you observe similar phenomenon? |
The unit is cm. |
The unit in our pose file (street/pose and aerial/pose) is 10000cm. If you use the pose file to train nerf, you can scale the depth file with 10000. |
Same problem as @ChaoyiZh. Is there any solution? |
Besides, could you tell me the which json file you use? |
Yes. I totally understand we are using Nerf(OPENGL), which is a right-hand coordinate system. And I can generate one pointcloud with some image-depth pair and the corresponding pose. Here are the files I am using. |
Thx! I will try to fix this bug. |
Hi, have you solve this problem? I am trying to build point cloud too, but face the same problem as you. |
Hi, would you mind sharing more details about your implementation? I tried |
Thanks, with below operations, the points align successfully:

Currently, we do not provide the depth map without anti-alias. If you want to use the depth map to guide reconstruction, I think the depth map with anti-alias is more suitable because it aligns with rgb images. If you want to use the depth map to obtain geometry, you can refer to https://github.com/city-super/MatrixCity/blob/main/MatrixCityPlugin/docs/Render-Data.md#depth to render the depth map without anti-alias, we have already provided the camera sequences, render config, plugin and detailed documentation. |
we have updated the script extracting point clouds from multi rgb-depth pairs at https://github.com/city-super/MatrixCity/blob/main/scripts/rgbd2pc.py @ChaoyiZh @yzslab @Goochaozheng @Snosixtyboo |
Thank you for your excellent work!
I've downloaded the test set from the website and converted the depth image into point cloud using the following code:
The shape of the point cloud seemed nice, however there seemed to be a noticeable amount of noise in the point cloud.
Is this normal or am I using a wrong way to convert the exr file?
I'm opening
0000.exr
