Automatic License Plate Recognition (ALPR, ANPR) on Kubernetes

Get high-accuracy, developer-friendly automatic license plate recognition (ALPR) or automatic number plate recognition (ANPR) on Kubernetes!

Our machine-learning software:

• Works on dark, low-res, blurry images and tough angles, all vehicle types, etc. See our full ALPR results.
• Works on Video URLs such are RTSP or Video Files
• Decodes license plate , vehicle type (e.g. SUV, van, pickup truck), vehicle make model (e.g. Honda Accord), color, and orientation. Ignores bumper stickers, car signs, etc.
• Is optimized for all 50 USA States, India, Brazil and 90+ countries worldwide.

Get license plate reader deployed on Kubernetes using Helm Charts in under 60 minutes:

• Access a simple REST API for easy integration in 8+ programming languages.
• Returns results via JSON Response or Webhooks.
• Has fast inference speed up to 21 ms.
• Runs on-premise on Linux, Windows, Mac, Jetson , Kubernetes, Raspberry Pi, Zynq, 96Boards, LattePanda and more.

ALPR, ANPR software on Kubernetes is ideal for parking, toll, police surveillance, community security, and other use cases.

Our license plate recognition (LPR) software can also forward results to our full ALPR Dashboard and Parking Management software solution, ParkPow.

Installation

Instructions to install Plate Recognizer Snapshot or Stream SDK on Kubernetes cluster. Requirements:

1. Setup your Kubernetes cluster. For example, https://kubernetes.io/docs/tasks/tools/install-minikube/
   • If using Minikube, make sure to enable the following addons dashboard ingress helm-tiller
2. Get helm from https://github.com/helm/helm/releases
3. Clone this repository git clone https://github.com/parkpow/helm-charts.git and cd helm-charts

Snapshot SDK

1. Contact support to enable Kubernetes for your account. License without Kubernetes enabled requires a persistent volume: persistence.enabled=true
2. Install chart helm install platerec-snapshot snapshot/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

Configuration

• To upgrade the chart, do helm upgrade platerec-snapshot snapshot/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>
• To delete the deployment, do helm delete platerec-snapshot
• To use the gpu version instead of the cpu version, do helm install platerec-snapshot snapshot/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY> --set image.repository=platerecognizer/alpr-gpu
• To deploy to a different namespace other than default, include --namespace <namespace-name> to the install/upgrade command as so helm install platerec-snapshot snapshot/ --namespace <namespace-name> --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

---

Configurations variables that can be changed (by adding them to the install command using --set parameter)

Parameter	Description	Default	Options
TOKEN	PlateRecognizer Token (required)	nil
LICENSE_KEY	PlateRecognizer Snapshot License (required)	nil
replicaCount	Number of Pods to run	1
image.repository	Plate Recognizer sdk	platerecognizer/alpr	Any from Command Selector
image.pullPolicy	Image pull policy	Always	[Always, IfNotPresent]
image.pullSecrets	Specify docker-registry secret names as an array	[]	True
service.annotations	Service annotations	{}
service.type	Kubernetes Service type	ClusterIP	[LoadBalancer, ClusterIP]
service.port	Service HTTP port	8080
persistence.enabled	Enable persistence using PVC	false
persistence.existingClaim	Enable persistence using an existing PVC	nil
persistence.storageClass	PVC Storage Class	nil (uses alpha storage class annotation)
persistence.accessMode	PVC Access Mode	ReadWriteOnce	[ReadWriteMany, ReadWriteOnce ]
persistence.size	PVC Storage Request	1Gi

Stream SDK

Install chart helm install platerec-stream stream/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

Configuration

• Update Stream config by editing configmap.yaml then restart services for changes to take effect by upgrading the chart.

  To use Stream configuration through Cloud, disable the configmap volume mount so configs get loaded from Cloud on container start.

• To upgrade the chart, do helm upgrade platerec-stream stream/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>
• To delete the deployment, do helm delete platerec-stream
• To deploy to a different namespace other than default, include --namespace <namespace-name> to the install/upgrade command as so helm install platerec-stream stream/ --namespace <namespace-name> --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

---

Configurations variables that can be changed (by adding them to the install command using --set parameter)

Parameter	Description	Default	Options
TOKEN	PlateRecognizer Token (required)	nil
LICENSE_KEY	PlateRecognizer Stream License (required)	nil
fileUpload	Enable service for File Upload	false	[true, false]
image.repository	Plate Recognizer sdk	platerecognizer/alpr-stream	Any from Command Selector
image.pullPolicy	Image pull policy	Always	[Always, IfNotPresent]
image.pullSecrets	Specify docker-registry secret names as an array	[]	True
service.annotations	Service annotations	{}
service.type	Kubernetes Service type	ClusterIP	[LoadBalancer, ClusterIP]
service.port	Service HTTP port	8080
persistence.existingClaim	Enable persistence using an existing PVC	nil
persistence.storageClass	PVC Storage Class	nil (uses alpha storage class annotation)
persistence.accessMode	PVC Access Mode	ReadWriteOnce	[ReadWriteMany, ReadWriteOnce ]
persistence.size	PVC Storage Request	10Gi

The service options only apply when fileUpload=true

Minikube Notes

To access the instance when using a custom cluster in Minikube, run the following command:

• Simulate a load balancer minikube tunnel
• Then run the commands shown after the helm install command.
• You can also use this command to get the extenal_id kubectl get --namespace default svc -w platerec-sdk-test-platerec-helm
• Finally call the SDK endpoint with curl -F 'upload=@/path/to/car.jpg' http://<external_ip>:8080/alpr
• Another option of accessing minikube services minikube service platerec-stream
