How to get the depth camera intrinsics #81
Comments
I have a repository with all the mapper functions if you want to check it out: https://github.com/KonstantinosAng/PyKinect2-Mapper-Functions For the depth camera intrinsics you can use the code below: from pykinect2.PyKinectV2 import * kinect = PyKinectRuntime.PyKinectRuntime(PyKinectV2.FrameSourceTypes_Depth | PyKinectV2.FrameSourceTypes_Color) while True: Just make sure to have at least one depth frame otherwise the intrinsics matrix will return zero values. and to access the values use: focal_length_x = intrinsics_matrix.FocalLengthX |
Thank you so much!
It works!

How can I get the internal parameters of the kinect color camera? There should be a corresponding function, but I can't find it?I guess the color camera intrinsics function like GetColorCameraIntrinsics(),but it does not exist. |
Yes there is only a function to get the Depth intrinsic parameters: intrinsics_matrix = kinect._mapper.GetDepthCameraIntrinsics() But you can always calibrate the RGB sensor and calculate the intrinsics yourself. |
From the source code, I see there is method in PyKinectV2 to get depth camera intrinsics.
However, I have no idea how to call this function.
Can you give an example how to use these com methods?
Thanks.
