Independent horizontal and vertical focal length parameters in nvdewarper in projection

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): RTX Titan
• DeepStream Version: 6.0
• NVIDIA GPU Driver Version (valid for GPU only): 465
• Issue Type( questions, new requirements, bugs): Question

After calibrating the cameras, we have different parameters for horizontal and vertical focal length, but nvdewarper only takes one (focal-length). Is there a way of passing the two of them for projection undistortion?

We need some internal discussion before reach to you.

Current gst-dewarper does not support two focal lengths. If you need such feature, you may need to customized a new plugin to use your own algorithm to handle such kind of camera data. We may consider to open source gst-dewarper in the future.

Perfect, I am super interested in the source code for the dewarper then. Thanks for your quick answers!
