# InspireFace Python API
|
||
|
||
InspireFace 提供了简单易用的 Python API,通过 ctypes 封装底层动态链接库实现。您可以通过 pip 安装最新发布版本,或使用项目自行编译的动态库进行配置。
|
||
|
||
## 快速安装
|
||
|
||
### 通过 pip 安装(推荐)
|
||
|
||
```bash
|
||
pip install inspireface
|
||
```
|
||
|
||
### 手动安装
|
||
|
||
1. 首先安装必要的依赖:
|
||
```bash
|
||
pip install loguru tqdm opencv-python
|
||
```
|
||
|
||
2. 将编译好的动态库复制到指定目录:
|
||
```bash
|
||
# 将编译好的动态库复制到对应系统架构目录
|
||
cp YOUR_BUILD_DIR/libInspireFace.so inspireface/modules/core/SYSTEM/CORE_ARCH/
|
||
```
|
||
|
||
3. 安装 Python 包:
|
||
```bash
|
||
python setup.py install
|
||
```
|
||
|
||
## 快速开始
|
||
|
||
以下是一个简单的示例,展示如何使用 InspireFace 进行人脸检测和关键点绘制:
|
||
|
||
```python
|
||
import cv2
|
||
import inspireface as isf
|
||
|
||
# 创建会话,启用所需功能
|
||
session = isf.InspireFaceSession(
|
||
opt=isf.HF_ENABLE_NONE, # 可选功能
|
||
detect_mode=isf.HF_DETECT_MODE_ALWAYS_DETECT # 检测模式
|
||
)
|
||
|
||
# 设置检测置信度阈值
|
||
session.set_detection_confidence_threshold(0.5)
|
||
|
||
# 读取图像
|
||
image = cv2.imread("path/to/your/image.jpg")
|
||
assert image is not None, "请检查图像路径是否正确"
|
||
|
||
# 执行人脸检测
|
||
faces = session.face_detection(image)
|
||
print(f"检测到 {len(faces)} 个人脸")
|
||
|
||
# 在图像上绘制检测结果
|
||
draw = image.copy()
|
||
for idx, face in enumerate(faces):
|
||
# 获取人脸框位置
|
||
x1, y1, x2, y2 = face.location
|
||
|
||
# 计算旋转框参数
|
||
center = ((x1 + x2) / 2, (y1 + y2) / 2)
|
||
size = (x2 - x1, y2 - y1)
|
||
angle = face.roll
|
||
|
||
# 绘制旋转框
|
||
rect = ((center[0], center[1]), (size[0], size[1]), angle)
|
||
box = cv2.boxPoints(rect)
|
||
box = box.astype(int)
|
||
cv2.drawContours(draw, [box], 0, (100, 180, 29), 2)
|
||
|
||
# 绘制关键点
|
||
landmarks = session.get_face_dense_landmark(face)
|
||
for x, y in landmarks.astype(int):
|
||
cv2.circle(draw, (x, y), 0, (220, 100, 0), 2)
|
||
```
|
||
|
||
## 更多示例
|
||
|
||
项目提供了多个示例文件,展示了不同的功能:
|
||
|
||
- `sample_face_detection.py`: 基础人脸检测
|
||
- `sample_face_track_from_video.py`: 视频人脸跟踪
|
||
- `sample_face_recognition.py`: 人脸识别
|
||
- `sample_face_comparison.py`: 人脸比对
|
||
- `sample_feature_hub.py`: 特征提取
|
||
- `sample_system_resource_statistics.py`: 系统资源统计
|
||
|
||
## 运行测试
|
||
|
||
项目包含单元测试,您可以通过修改 `test/test_settings.py` 中的参数来调整测试内容:
|
||
|
||
```bash
|
||
python -m unittest discover -s test
|
||
```
|
||
|
||
## 注意事项
|
||
|
||
1. 确保系统已安装 OpenCV 和其他必要依赖
|
||
2. 使用前请确保动态库已正确安装
|
||
3. 建议使用 Python 3.7 或更高版本
