Helper library for interacting with Landing AI LandingLens

LandingLens Python SDK

The LandingLens Python SDK contains the LandingLens development library and examples that show how to integrate your app with LandingLens in a variety of scenarios. The examples cover different model types, image acquisition sources, and post-procesing techniques.

We've provided some examples in Jupyter Notebooks to focus on ease of use, and some examples in Python apps to provide a more robust and complete experience.

Example	Description	Type
Poker Card Suit Identification	This notebook shows how to use an object detection model from LandingLens to detect suits on playing cards. A webcam is used to take photos of playing cards.	Jupyter Notebook
Door Monitoring for Home Automation	This notebook shows how to use an object detection model from LandingLens to detect whether a door is open or closed. An RTSP camera is used to acquire images.	Jupyter Notebook
Streaming Video	This application shows how to continuously run inference on images extracted from a streaming RTSP video camera feed.	Python application
Satellite Images and Post-Processing	This notebook shows how to use a Visual Prompting model from LandingLens to identify different objects in satellite images. The notebook includes post-processing scripts that calculate the percentage of ground cover that each object takes up.	Jupyter Notebook

Install the Library

pip install landingai

Quick Start

Prerequisites

This library needs to communicate with the LandingLens platform to perform certain functions. (For example, the Predictor API calls the HTTP endpoint of your deployed model). To enable communication with LandingLens, you will need the following information:

1. The Endpoint ID of your deployed model in LandingLens. You can find this on the Deploy page in LandingLens.
2. The API Key and API Secret for the LandingLens organization that has the model you want to deploy. To learn how to generate these credentials, go here.

Run Inference

Run inference using the endpoint you created in LandingLens:

• Install the Python library.
• Create a Predictor fucntion with your Endpoint ID, API Key, and API Secret.
• Call the predict() function with an image (using the NumPy array format).

from landingai.predict import Predictor
# Find your API key and secrets
endpoint_id = "FILL_YOUR_INFERENCE_ENDPOINT_ID"
api_key = "FILL_YOUR_API_KEY"
api_secret = "FILL_YOUR_API_SECRET"
# Load your image
image = ...
# Run inference
predictor = Predictor(endpoint_id, api_key, api_secret)
predictions = predictor.predict(image)

See a working example in here.

Visualize and Save Predictions

Visualize your inference results by overlaying the predictions on the input image and saving the updated image:

from landingai.visualize import overlay_predictions
# continue the above example
predictions = predictor.predict(image)
image_with_preds = overlay_predictions(predictions, image)
image_with_preds.save("image.jpg")

Run Examples Locally

All the examples in this repo can be run locally.

To give you some guidance, here's how you can run the rtsp-capture example locally in a shell environment:

1. Clone the repo to local: git clone https://github.com/landing-ai/landingai-python.git
2. Install the library: poetry install --with examples (Note: See Developer Guide for how to install poetry)
3. Activate the virtual environment: poetry shell
4. Run: python landingai-python/examples/capture-service/run.py
