I Got it. Thanks
Can you provide more details about depth completion? I use the TWISE, and get the following image
The original image corresponding to this image is as follows
So I don't know what to do. Can you help me?
Hi, is the second image the dense depth map we provided? How do you get the first image? In our experiments, we first project the raw point clouds to image space, getting a sparse dense depth map, then we feed the sparse depth map and corresponding RGB image to TWISE, getting a dense depth map (the second image).
My code for projecting point clouds into depth images:
I use get_ lidar_ in_ image_ FOV
function to project the point cloud in the camera's perspective into a depth image. The shape of the depth image is 352 * 1216.
First, I project the point cloud into a sparse depth image and then use the depth completion method to complete the sparse depth image. However, the depth value of the depth image after I complete is different from the depth image you provide, and the difference is quite large.
For example, the maximum depth value of the sample 000085.png
in the training folder you provided is 21299. But the maximum depth value after I complete is 19962.
I have verified whether there is any problem in the coordinate calculation of my point cloud to depth image projection. I binarize the depth values of both the dense depth map you provided and the dense depth map I completed myself, 0 or 255. Then I found that the depth map I completed is exactly the same as the depth map you provided.
So I don't know where there is a problem with my data preprocessing.I'm looking forward to your answer.
The following figure is provided in your dataset.
The following figure is the sparse depth image I converted from point cloud through matrix calculation.
The following figure is the dense depth image I generated from the sparse depth image through TWISE.
Hi, we will release the codes about how to generate pseudo point clouds in Here this month. Be waiting~
好的,谢了大兄弟。
Hi, the codes that generate pseudo point clouds have been released, please refer to SFD-TWISE.
Thank you for sharing the code. I compared my code with yours and found the problem with my original code.
Nice work! And I just get good results in kitti .
But I have a question about the depth_dense_twise datasets, these are depth images and add rgb imgs concat to pc_velo_rgb_seg_uv. where can I get depth images , are these second 12G datasets from the web Download right color images, if you want to use stereo information?
Thanks.
