Parking, finally explained
The nearest free parking space. Found.
The sign says 30 spaces are free. It does not say where. P-Rex watches the lot with a camera and shows every space as free or taken, so nobody has to circle the lot to find out.
A really annoying problem
Most lots can count cars in and out. That is not the same as knowing where to park.
A count is not a location
"30 free" still means driving every row to find them, and the last spaces often stay empty because people give up.
A wrong number is worse than none
Once a display shows the wrong figure, people stop trusting it, and it gets switched off.
Gravel has no sensors
Many lots are gravel or have changing layouts. Sensors in the ground are expensive to maintain and do not fit.
How it works
One camera on a mast or facade covers many spaces. The thinking happens on the camera.
A camera sees the lot
It is mounted above the spaces and needs no work on the ground.
A small model decides
On the device, each space is marked free, taken or unknown.
Only the status is sent
Images and number plates stay on the camera. What leaves is a list of spaces and their status.
You see where to park
A map or sign shows the nearest free space, and facility teams get the history.
Built to be trusted
The goal is a display people believe.
Unknown, not wrong
If the model is unsure or data is old, P-Rex says "unknown" instead of guessing.
Private by design
Processing on the device means no pictures of cars or people are sent or stored.
Made for facility teams
Staff can sign in to see a lot and download occupancy data for planning.
STATUS: PROTOTYPE, TESTED ON PHOTOS OF A REAL LOT.
