curl --request POST \
  --url https://api.anyline.com/v2/meter/emea/barcode \
  --header 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
  --data '{image: "yourBase64Image"}'

Be sure to replace YOUR_ACCESS_TOKEN with your actual access-token, and the "yourBase64Image" String with the blob for the image you wish to scan.

After the call has been sent, you will receive a result including a JSON file like the following example:

{
  "fieldConfidences": {
    "serial_numbers": [
      0.8923537880182266
    ],
    "unit": null,
    "value": 0.9984918302959866
  },
  "serial_numbers": [
    "1519583"
  ],
  "unit": null,
  "value": "136587.6",
  "barcodes": [
    {
      "value": "1049110015195831",
      "format": "CODE_128",
      "coordinates": [
        665,

And that’s it! You’ve successfully scanned an image using the Meter EMEA Barcode API!

Scan Meter EMEA Barcode in strict mode

The Meter EMEA Barcode API can be used in strict mode. This means that the API will only return results if it meets a certain confidence threshold. To use the strict mode, you need to set the strict parameter to true in the request body.

curl --request POST \
  --url https://api.anyline.com/v2/meter/emea/barcode \
  --header 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
  --data '{image: "yourBase64Image", strict: true}'

Scan capability overview

The Anyline Meter EMEA Barcode Cloud API currently supports extraction of 2 meter information points and 3 barcode information points:

Meter Value
Serial Numbers
Content of the barcodes
Format of the barcodes
Position (X,Y coordinates) of barcodes on the input image

The Meter Unit is no longer extracted in the latest version. To ensure compatibility of the result JSON structure, the unit field will still be included with a null value.

Meter Value

The Anyline Meter EMEA Barcode Cloud API extracts analog and digital meter values.

Analog Meters

Analog meter values are characterized by mechanically rotating digits. This includes gas-, electric-, and water meters. The scanning includes automatic detection of digits before and after the decimal point. A typical example of an analog meter value can be seen below.

Digital Meters

Digital meter values are characterized by digits being displayed on an LCD display, typically a 7-segment digital display. This includes digital gas-, electric-, and water meters, as well as heat meters. A typical example of an digital meter value can be seen below.

Examples

Serial Numbers

In general, at least one serial number is located on the meter, which is the manufacturing serial number. In some cases, there are more than one serial number on the electricity meter, which are typically provided by the electricity supplier.

The Anyline Meter EMEA Barcode Cloud API extracts all serial numbers on the meter, sorts them based on the vertical size of the serial numbers, and returns them in an array. All special characters besides numbers and letters are filtered out, and the returned text is in a capital letter format.

Typical examples of serial numbers on analog and digital meters can be seen below.
