RGBD alignment? #2

Open wangxihao opened 3 years ago

wangxihao commented 3 years ago

Is RGBD data made from color mapping to depth(resolution smaller ) or depth mapping to color(resolution smaller)? The former will result a circle of black around the mapped color image and the latter will make the resolution of depth bigger, and due to interpolation involved, some depth values ​​are not accurate. Thank you!

The concept of RGBD alignment does not really look at which one is registered first. Make sure the dimension and resolution of RGB and depth images are similar before the registration takes place.

Regarding you question about your issue, the black circles might be due to inaccurate matching to rgb pixels to depth values. What registration technique are you using?

Thank you.First I use the intrinsics parameters of the depth camera to obtain the point cloud, then use the extrinsics parameters and the intrinsics parameters of the color camera to project the point cloud onto the color image, and obtain the aligned color image according to the projection result.

what camera is being used here?
