2 ways of Fisheye Dewarp


Fisheye Dewarp Mechanism

Dewarp on Camera (Edge)

• Camera send dewarped video• Playback can’t further operate• Live view control is not smooth

Dewarp on Client (Host)

• Camera send original video• Live view/ playback flexible and smooth operation

Observation


Dilemma of Fisheye Dewarp


Dilemma 1

Camera vendor choices

User

Flexibility

Client Dewarp: Additional integration

Camera Dewarp: No flexibility on operation


Dilemma 2

Dewarp CPU resource

General client dewarp test result: (one camera)

Before dewarp: CPU 17%

After dewarp: CPU 27%

Drag PTZ: CPU 38%

Image Quality


NUUO Solution: Dilemma 1

Camera vendor choice

Usage Flexibility

Client Dewarp: Additional integration

Camera Dewarp: No flexibility on operation

NUUO Dewarp 1.0: Client generic dewarp for all fisheye camera


New Dilemma…

Generic Dewarp

Dewarp Accuracy

Camera model, Lens, Warp way, installation way… will impact the dewarp result

NUUO Dewarp Calibration:• Device Pack calibrate by models when integrate

• Calibration tool for user optimization


Why Calibration Important?

After CalibrationNo Calibration


NUUO Solution: Dilemma 2

Client Dewarp:



Drag PTZ: CPU 38%

Dewarp CPU resource Image

Quality

NUUO GPU Acceleration

Full Resolution


Like multi-core CPU, specially for decoding

GPU Acceleration plus Full Resolution



Drag PTZ: CPU 31%



Drag PTZ: CPU 38%

Normal Full ResolutionNUUO adopt OpenCL

Better Platform compatibility

Better quality, Lower CPU consumption


NUUO Dewarp v2.0

Plugin Disadvantage

Complex process

Repeat for every camera brand

If camera vendor not develop plugin – camera dewarp or can not dewarp…
