License plate verifier API

The VAPIX® License plate verifier API contains the information and steps that makes it possible to detect and recognize license plates and whether the vehicle should be allowed to enter a restricted area such as a parking garage. It is split into three groups that handles everything from settings to how to query events and retrieve real time data from the system:

VAPIX events
Push events (HTTP, TCP, FTP)
Heartbeat services
Direct integration
Application API
Web services API

Analytic (ALPV) event types

The following table contain event types for the real-time, new, update and lost statuses.

#	RAW recognition event, time ms	Number plate	Car ID	LPR event (VAPIX ALLPLATES)	Comments
1	10:12:10 AM 100	AA7690EQ	123	~10:12:10 AM 100 LPR Event - NEW -AA7690EQ	Events are sent immediately.
2	10:12:10 AM 150	AA7690EQ	123	~10:12:10 AM 400 LPR Event - UPDATE - AA7690EQ	A direction has been detected. An event has been sent.
3	10:12:10 AM 200	AA7690EQ	123
4	10:12:10 AM 250	AA7690EO	123
5	10:12:10 AM 350	AA7690EO	123
6	10:12:10 AM 400	AA7690EO	123	~10:12:10 AM 400 LPR Event - UPDATE - AA7690EO	A license plate has been changed. An event has been sent.
7	10:12:10 AM 450	AA7690EO	123
8	10:12:10 AM 750	AA7690EO	123
9	10:12:10 AM 850	AA7690EO	123
10	License plate left the frame		123
11	10:12:16 AM 050	----/----	123456789	~10:12:15 AM 1050 LPR Event - LOST- AA7690EO	An event has been sent after the last license plate recognition +10 s.

A NEW event is generated on the first license plate detection (the direction is always undefined in this event).
The Update event is generated if direction, license plate, zone, etc. changes.
The LOST event is generated +10 seconds after the last recognition (this is a configurable parameter).

Examples

The ACAP will generate two events, NEW at first detection and LOST +10 seconds after the first detection.

Access control systems (real-time systems) use NEW and UPDATE events to check and open barriers. In traffic solutions, LOST events are used to get the final result. This means one car for every event.

Use the CARID field in the package to merge or update all events into one. This field is unique and the can be used by NEW, UPDATE and LOST for one vehicle.

VAPIX Events

Real time recognition events can be received from a camera using VAPIX protocols in a format where all recognition related data except images are present. For more information see Event data streaming.

Events and Examples

ALPV.ALLPlates

This general metadata event is always available and contains all data from the LPR engine. The event can be sent several times for each individual license plate:

NEW: Used when a new License plate is detected. Only one event is produced and it does not contain direction.
UPDATE: Used when something changes in the LPR package. Multiple events can be produced depending on the changes of the LPR package and how long the license plate is on the scene.
LOST: Used when a vehicle exits the image. Only one image event is produced (sent +10 seconds after the last UPDATE event).

Parameter	Description
`Width`	The width of the license plate, measured in pixels.
`carMoveDirection`	The detected movement against a set of pre-set directions.
`roIID`	ID of an area of interest where the plate was recognized.
`vehicleType`	The vehicle type. Can be CAR \| TRUCK \| BUS. This is parameter is supported from ALPV 2.9.19 or later.
`View`	The vehicle’s view. Can be front \| rear.
`Top`	The top coordinate of the license plate, measured in pixels.
`consumedTime`	The license plate recognition time, measured in milliseconds (ms).
`Text`	The license plate text.
`iso3166-2`	The iso3166-2 code.
`Region`	The local region name.
`listName`	The name of the list. It will be empty if the plate text cannot be found in the list, or labelled on either the Block list or Allow list if it exists.
`regionCode`	The region letter.
`Left`	The left coordinate of the license plate, measured in pixels.
`capture_timestamp`	The UNIX frame timestamp.
`listDescription`	The plate’s description if it was added to a list.
`lpImage`	The license plate image in Base64 (supported from ALPV 2.9.19 or later).
`action`	Set to either `Accepted`, `Denied` depending on whether an application configuration has occurred.
`vehicleColor`	The color of the vehicle. This is parameter is supported from ALPV 2.9.19 or later.
`carID`	The internal runtime plate ID.
`country`	The 3 letter country names in the Alpha-3 ISO-3166 format.
`height`	The height of the license plate, measured in pixels.
`frame_timestamp`	The UNIX frame timestamp from the camera.

Push events

Data format of received data

TCP: Data formats are JSON files and base64-encoded pictures in the JSON body.
HTTP: Data formats are JSON files and JPG images (or base64-encoded pictures in the JSON body with non-multipart requests).
FTP: Data format is JPG images.

The following events can be sent several times for each individual license plate:

NEW: Used when a new License plate is detected. Only one event is produced and it does not contain direction.
UPDATE: Used when something changes in the LPR package. Multiple events can be produced depending on the changes of the LPR package and how long the license plate is on the scene.
LOST: Used when a vehicle exits the image. Only one image event is produced (sent +10 seconds after the last UPDATE event).

Using TCP

TCP send events to a configured TCP receiver. A JSON body must be used by LPV to send appropriate event images in base64.

Receiver example

Use this method when you want to receive data that can be stored as files using PHP.

PHP

<?php

# Create files in the following directory
$uploaddir = 'log/';

# Set path and filename where to store the event
$uploadfile = $uploaddir . basename($_FILES['event']['name']);

# Store the JSON file on disk
if (move_uploaded_file($_FILES['event']['tmp_name'], $uploadfile)) {
  # All good, do other things here
} else {
  # Failed moving file, do proper error handling
}

# Set path end filename where to store the image
$uploadfile = $uploaddir . basename($_FILES['image']['name']);

# Store the image file on disk
if (move_uploaded_file($_FILES['image']['tmp_name'], $uploadfile)) {
  # All good, do other things here
} else {
  # Failed moving file, do proper error handling
}

?>

Python

import json
from aiohttp.web import Response, Application, run_app, post

async def handle_files(request):
  print("-----new request-----")
  data = await request.post()
  for field_name, file_field in data.items():

    if field_name == 'event':
      json_event = json.loads(file_contents)
      print(f'Event: {json_event}')
  return Response(status=200)

if __name__ == '__main__':
  app = Application()
  app.add_routes([post('/', handle_files)])
  run_app(app, host='0.0.0.0', port=5001)

Field	Description
`URL`	The encoded target base64 URL. Determines the data that should be pushed to the URL or IP address using the format `<IP>:port/path`. No path is present when the TCP option is used, however the IP and port is still available.
`Latitude`	The camera latitude coordinates, represented by a float number.
`Longitude`	The camera longitude coordinates, represented by a float number.
`sensorProviderID`	The camera identifier that is sent with all requests when multiple cameras are running to separate them.
`Protocol`	The protocol that is sent. `TCP` = 8 `HTTP` = 1 `FTP` = 16
`Enable`	True: The function is enabled. False: The function is disabled.
`skip_image_in_post`	True: Sends the JSON packet, but no images. False: Sends both the JSON packet and images.
`event_new`	Sends NEW events. Can be either true or false.
`event_update`	Sends UPDATE events. Can be either true or false.
`event_lost`	Sends LOST events. Can be either true or false.
`use_multipart`	True: Sends as multipart/form-data. False: Sends as application/json.
`use_event_buffer`	Events will be re-sent from a buffer if the target URL is not accessible. Can be either true o false.
`User`	The user name.
`Password`	The password.
`http_auth_type`
`send_second_image`	Sends a second image with the License plate type alongside the regular image configured in the LPV settings. Can be either true or false.
`path_template`	The custom path for FTP.
`x_auth_key`	The Auth-Header.
