Visualizing the Results

A test run, with results composited onto the footage in After Effects.

An Ethical Dilemma

Back to the Results

“Nothing is impossible until it is proven to be.”

Optimal ALPR Camera Setups

Optical Zoom

Angle & Positioning

What a front facing ALPR camera sees — not much.
A four camera array would need to be angled similar to this. Icons from Freepik.

A Gymbal

Any production-ready version of a vehicle-mounted ALPR needs some form of stabilisation. Not a hand.

Other Important Factors

Frame Rate

Idea: how vehicle object detection could remove ALPR frame limits by processing asynchronously.

Frame Rate vs Shutter Speed

Rolling shutter issues on a Contour HD @ 60km/h.

Open ALPR Version

ALPR Country Training Data

Slimline Australian plates need their own separate country detection to regular Australian plates?
Good luck with that.
