AI Technical Summary
Technical Problem
Mobile shooting devices cause image shakiness and dizziness due to device shaking during shooting, and existing technologies struggle to maintain image quality in scenes with significant movement.
Method used
The first camera virtual pose of the target frame is determined by using the camera virtual pose and camera motion data based on the reference frame. Image transformation and filtering parameter optimization are then performed to obtain the second camera virtual pose without jitter.
Benefits of technology
It achieves accurate estimation of shake-free pose, improves shooting quality, adapts to different shooting scenarios, reduces computing power requirements, and is suitable for real-time processing on mobile devices.
