## 1.Overview
|
||||
|
||||
YOLOv8 was released by Ultralytics on January 10, 2023, offering cutting-edge performance in terms of accuracy and speed. Building upon the advancements of previous YOLO versions, YOLOv8 introduced new features and optimizations that make it an ideal choice for various [object detection](https://www.ultralytics.com/blog/a-guide-to-deep-dive-into-object-detection-in-2025) tasks in a wide range of applications.

|
||||
|
||||
## 4. Demo Run
|
||||
|
||||
### CPP
|
||||
|
||||
#### 1. Compile
|
||||
|
||||
**Prerequisites:**
|
||||
- Android NDK (r25e recommended)
|
||||
- `ANDROID_NDK_PATH` environment variable set
|
||||
|
||||
**Build:**
|
||||
```bash
|
||||
# Build for arm64-v8a
|
||||
cd examples/yolov8/cpp
|
||||
./build-android.sh -a arm64-v8a
|
||||
```
|
||||
|
||||
The executable will be generated at `build/android/yolov8_demo` (Note: executable name may vary, verify in build folder).
|
||||
|
||||
#### 2. Run
|
||||
|
||||
```bash
|
||||
# Push executable to device
|
||||
adb push build/android/yolov8_demo /data/local/tmp/
|
||||
adb push model/yolov8s_int8_A311D2.adla /data/local/tmp/
|
||||
adb push test_image.jpg /data/local/tmp/
|
||||
|
||||
# Run on device
|
||||
adb shell
|
||||
cd /data/local/tmp
|
||||
chmod +x yolov8_demo
|
||||
export LD_LIBRARY_PATH=/vendor/lib64 or (/vendor/lib)
|
||||
|
||||
# Usage: ./yolo_world_demo <model_path> <image_path>
|
||||
./yolov8_demo yolov8s_int8_A311D2.adla test_image.jpg"
|
||||
```
|
||||
|
||||
**Note:** Replace `yolov8s_int8_A311D2.adla` with your actual model file path.
|
||||
|
||||
### Python
|
||||
|
||||
**Prerequisites:**
|
||||
- Python 3.10
|
||||
- Required packages: `numpy`, `opencv-python`, `amlnnlite`
|
||||
|
||||
**Install dependencies:**
|
||||
```bash
|
||||
pip install numpy opencv-python amlnnlite-1.0.0-cp310-cp310-linux_aarch64.whl
|
||||
```
|
||||
|
||||
**Run on device:**
|
||||
```bash
|
||||
python yolov8.py --model-path ./yolov8s_int8_A311D2.adla
|
||||
```
|
||||
|
||||
The script will automatically process all image files (`.jpg`, `.jpeg`, `.png`, `.bmp`) in the current directory and save results to a `{model_name}_result` folder.
|
||||
|
||||
## 5.Results
|
||||
The program will print the detection count and inference time. The result image with bounding boxes will be saved to the specified output path (`result.jpg` by default).
|
||||
|
||||
|
||||
You can pull the result image back to view it:
|
||||
```bash
|
||||
adb pull result.jpg.
|
||||
```

|
||||
```
|
||||
- **Priority 3 – Sibling directory fallback** *(automatic)*
|
||||

|
||||
```bash
|
||||
git clone git@github.com:Amlogic-NN/amlnn-toolkit.git ../amlnn-toolkit
|
||||
```
