camera

# Camera Control Skill Control the local computer's built-in camera for capturing photos and basic operations. ## When to Use - User wants to take a photo using the computer camera - User asks to capture an image from the webcam - User wants to check the camera view - Commands like: "拍照", "打开摄像头", "拍张照片", "camera", "webcam", "take a photo" ## Tools Required - Python 3 with OpenCV (`cv2`) - Standard library only (no extra deps beyond opencv-python) ## Usage ### Take a Photo Capture a single frame from the default camera: ```bash python3 skills/camera/scripts/camera.py capture --output "~/.openclaw/workspace/captures/photo_$(date +%Y%m%d_%H%M%S).jpg" ``` Or use the wrapper for default location: ```bash python3 skills/camera/scripts/capture.py ``` This saves to `~/.openclaw/workspace/captures/` with timestamp. ### List Available Cameras ```bash python3 skills/camera/scripts/camera.py list ``` ### Test Camera (preview window, auto-close after 3 seconds) ```bash python3 skills/camera/scripts/camera.py preview --duration 3 ``` ## Output - Photo path is printed to stdout - Use this path with the `image` tool to analyze the captured photo - Photos are saved to `captures/` directory by default ## Examples **User:** "拍张照片" **Action:** Run capture script, then use `image` tool to show/analyze the photo. **User:** "看看摄像头画面" **Action:** Run preview script for 3 seconds to verify camera works. ## Notes - Default camera index is 0 (built-in webcam) - If you have multiple cameras, use `--camera 1`, `--camera 2`, etc. - On Windows, the script auto-detects and works with DirectShow backend - Captures directory is auto-created if it doesn't exist
