DepthAI SDK
DepthAI SDK is a Python package built on top of the depthai-python API library that improves ease of use when developing apps for OAK devices.
OakCamera class
The OakCamera class abstracts DepthAI API pipeline building, different camera permutations, stream recording/replaying, adds debugging features, handles AI model sourcing and decoding, does message syncing & visualization, and much more.
Script below demonstrates how you can easily accomplish complex tasks, that would otherwise take 100s of lines of code, and a few hours of assembling code pieces together.
1from depthai_sdk import OakCamera, ResizeMode
2
3# Download a public depthai-recording and replay it
4with OakCamera(replay='cars-tracking-above-01') as oak:
5 # Create color camera
6 color = oak.create_camera('color')
7
8 # Download & run pretrained vehicle detection model and track detections
9 nn = oak.create_nn('vehicle-detection-0202', color, tracker=True)
10 nn.config_nn(resize_mode=ResizeMode.STRETCH)
11
12 # Visualize tracklets, show FPS
13 visualizer = oak.visualize(nn.out.tracker, fps=True)
14 visualizer.tracking(line_thickness=5).text(auto_scale=True)
15
16 # Start the app in blocking mode
17 oak.start(blocking=True)
A public video gets downloaded and frames are sent to the OAK camera. On the OAK camera, we run vehicle-detection-0202,
which is an SDK supported model. Afterwards, we use object tracker for tracking these detections over
time. We visualize tracking results and configure visualizer to best fit our needs.

Note
This class will be in alpha stage until depthai-sdk 2.0.0, so there will likely be some API changes.
Installation
To install this package, run the following command in your terminal window
python3 -m pip install depthai-sdk
