Pelacakan gerakan

Di Android 9, perangkat kamera dapat mengiklankan
kemampuan pelacakan gerakan.
Kamera yang mendukung fitur ini tidak menghasilkan data pelacakan gerakan itu sendiri,
tetapi digunakan oleh ARCore atau algoritma stabilisasi gambar bersama dengan
sensor lain untuk analisis scene. Untuk mendukung fitur ini, perangkat harus mendukung
CONTROL_CAPTURE_INTENT_MOTION_TRACKING.
Jika intent ini adalah bagian dari permintaan pengambilan, kamera harus membatasi
waktu eksposur hingga maksimum 20 milidetik untuk mengurangi blur gerakan.
Contoh dan sumber
Penerapan pelacakan gerakan referensi di sisi HAL tersedia sebagai bagian
dari
Camera HAL.
Implementasi
Untuk mengaktifkan pelacakan gerakan di perangkat kamera, pastikan:
Validasi
Perangkat kamera yang mendukung fitur pelacakan gerakan harus lulus
pengujian CTS kamera.

To support this feature, devices must support\n[`CONTROL_CAPTURE_INTENT_MOTION_TRACKING`](https://developer.android.com/reference/android/hardware/camera2/CameraMetadata#CONTROL_CAPTURE_INTENT_MOTION_TRACKING).\nIf this intent is part of the capture request, the camera must limit the\nexposure time to a maximum of 20 milliseconds to reduce motion blur.\n\nExamples and source\n-------------------\n\nA reference motion tracking implementation on the HAL side is available as part\nof the\n[Camera HAL](https://android.googlesource.com/platform/hardware/qcom/camera/+/android16-release/msm8998/QCamera2/HAL3/QCamera3HWI.cpp).\n\nImplementation\n--------------\n\nTo enable motion tracking on a camera device, make sure:\n\n- The [`ANDROID_REQUEST_AVAILABLE_CAPABILITIES_MOTION_TRACKING`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.3/types.hal#230) capability is enabled.\n- The [`ANDROID_CONTROL_CAPTURE_INTENT_MOTION_TRACKING`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.3/types.hal#206) intent is supported and when included in a capture request limits the camera exposure time to a maximum of 20 milliseconds.\n- Lens calibration data from the following list is accurately reported in the\n static information and dynamic metadata fields:\n\n - [`ANDROID_LENS_POSE_ROTATION`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.2/types.hal#747)\n - [`ANDROID_LENS_POSE_TRANSLATION`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.2/types.hal#753)\n - [`ANDROID_LENS_INTRINSIC_CALIBRATION`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.2/types.hal#773)\n - [`ANDROID_LENS_RADIAL_DISTORTION`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.2/types.hal#780)\n - [`ANDROID_LENS_POSE_REFERENCE`](https://android.googlesource.com/platform/hardware/interfaces/+/android16-release/camera/metadata/3.3/types.hal#78)\n\nValidation\n----------\n\nCamera devices supporting the motion tracking feature must pass the\n[camera CTS tests](/docs/compatibility/cts/camera-hal#cts_tests)."]]
