The Moto algorithm identifies riders based on the number displayed on their motorbike, without relying on a bib worn by the rider.
💡 This article explains how the algorithm works and how to configure it. To find out when to select it during import, see the article “Steps for importing photos”.
How the algorithm works #
On each photo, Sportpxl detects the number displayed on the motorcycle — front plate, fairing number or vehicle number — and associates it with an athlete. The propagation logic is identical to other algorithms: a number correctly identified on one photo is automatically propagated to all photos where the same number appears in the album.
Typical use cases #
- Enduro, motocross, trial
- Motorcycle rally
- Any motorbike event with visible numbering on the vehicle
Configure the algorithm #
When importing, select the “Motorcycle” algorithm and enter the following parameters:
Min. bib number / Max. bib number Define the range of valid numbers for the event to avoid accidentally reading other numbers present in the scene.
Number format Specify whether numbers are numeric only or alphanumeric.
Words or numbers to exclude List recurring text found on motorcycles that does not correspond to a rider number.
Best practices for taking photographs #
- Photograph the motorcycle from the front or three-quarter front view to maximise the legibility of the number.
- Avoid strict back or profile angles where the number is missing or truncated.
- A tight focus on the front of the motorbike improves detection.
💡 If the number appears in several places on the motorbike (front plate + fairing), Sportpxl detects the most legible one. There is no need to focus on a specific location.
