Engine Region

When you run a plate analysis using the Vaxtor Cloud ALPR API you are targeting the default Plate Recognition Engine Region. This region matches your current physical region. If you wish to target a different PR Engine Region in your API calls, you need to provide the Vaxtor-Ocr-Region http header key with the appropriate Engine Region Code as the value.

Currently supported PR Engine Regions are listed below:

Engine Region 🌐	Code
APAC	apac
Central Asia	central-asia
Europe	europe
Middle East	middle-east
North America	north-america
Oceania	oceania

WARNING

Plate Recognition Engine Region selection is currently not supported for the free plan

Below a bash example use casing how to choose North America as the PR Engine Region

#!/bin/bash

API_URL="https://vaxtor.cloud/analysis/api/plate"
IMAGE_FILE="image.jpg"
ACCESS_TOKEN="Your access token"
 
# Analyze Image
RESPONSE=$(curl -s -X POST "$API_URL" \
    -H "Authorization: Bearer $ACCESS_TOKEN" \
    -H "Vaxtor-Ocr-Region: north-america" \
    -H "Content-Type: multipart/form-data" \
    -F "file=@$IMAGE_FILE")
 
# Show Result
echo $RESPONSE

Image Resolution

The Plate Recognition Engine automatically adjusts its detection behaviour based on the resolution of the submitted image.

• If the image resolution is greater than 320×240 pixels, the engine assumes the image contains a full vehicle and will perform detection accordingly.
• If the image resolution is 320×240 pixels or smaller, the engine assumes the image is a license plate crop and skips vehicle detection, focusing only on reading the plate.
