[D455] Camera Intrinsic Matrix

July 24, 2022 17:03

Hi,

I'm using Open3D to get the point cloud from the D455 camera. But open3D needs PinholeCameraIntrinsicParameters to calculate it.

Open3D has PinholeCameraIntrinsicParameters.PrimeSenseDefault command to get default parameters, but it's not ok. I think that we need real values from the camera.

So, how can I get CameraIntrinsic from the D455 camera?

Do you have the code of Open3D to get the point cloud from the D455 camera?

Thanks

Hi Nguyenduyduc14

I hope that the Open3D point cloud script at the link below will be a helpful reference.

Within that discussion, an example of using PinholeCameraIntrinsic is given.

pinhole_camera_intrinsic = PinholeCameraIntrinsic(intrinsic.width, intrinsic.height, intrinsic.fx, intrinsic.fy, intrinsic.ppx, intrinsic.ppy)
