sky-tracker-sdk 0.1.11

Sky Tracker — C++ tracking core with Python and Node.js SDK

Sky Tracker SDK

C++ tracking core for fast-moving small objects — drone, aircraft, bird detection and tracking. No GPU required.

Install

pip install sky-tracker-sdk

License

A valid license key is required at runtime. Set it as an environment variable:

# Windows
set SKY_TRACKER_LICENSE_KEY=SKT1.<your-token>

# Linux / macOS
export SKY_TRACKER_LICENSE_KEY=SKT1.<your-token>

Or drop a sky_tracker.lic file next to your script — the SDK finds it automatically.

Quick Start

import cv2
import sky_tracker

cap = cv2.VideoCapture("video.mp4")
ok, frame = cap.read()

tracker = sky_tracker.Tracker("default")
tracker.lock(frame, (469, 409, 26, 38))  # x, y, w, h

while cap.isOpened():
    ok, frame = cap.read()
    if not ok:
        break
    result = tracker.update(frame)
    if not result.lost:
        cx, cy = result.center()
        print(f"frame target at ({cx:.1f}, {cy:.1f})  confidence={result.confidence:.2f}")
