基于全志H616的智能家居

1.接线

2.配置语音模块

3.接上串口烧入安装包并且用电脑串口测试

4.板子测试语音模块

5.接入阿里云人脸识别

人脸识别示例代码的位置

导入并配置示例代码

修改“default” face.py

图片比对路径

修改文件名指令“mv”

获取score最大的值在数据库去开锁

将代码封装成函数并且只输出score的最大值只保留两位小数：

需要的数据把dict数据问AI用python写出来 face.py

运行结果：

实现c语言调用python代码 face.c

#include <Python.h>

void face_init(void)
{
    Py_Initialize();
    
    // 将当前路径添加到sys.path中
    PyObject *sys = PyImport_ImportModule("sys");
    PyObject *path = PyObject_GetAttrString(sys, "path");
    PyList_Append(path, PyUnicode_FromString("."));

}

void face_final(void)
{
	Py_Finalize();
}

double face_category(void)
{
    // 导入para模块
    PyObject *pModule = PyImport_ImportModule("face");
    if (!pModule)
    {
        PyErr_Print();
        printf("Error: failed to load face.py\n");
		goto FAILED_MODULE;
    }
    
    //获取say_funny函数对象
    PyObject *pFunc = PyObject_GetAttrString(pModule, "alibaba_face");
    if (!pFunc)
    {
        PyErr_Print();
        printf("Error: failed to load alibaba_face\n");
		goto FAILED_FUNC;
    }
    

    //调用say_funny函数并获取返回值
    PyObject *pValue = PyObject_CallObject(pFunc, NULL);
    if (!pValue)
    {
        PyErr_Print();
        printf("Error: function call failed\n");
		goto FAILED_FUNC;
    }
    
    //将返回值转换为C类型
    double result = 0.0;
    if (!PyArg_Parse(pValue, "d", &result))
    {
        PyErr_Print();
        printf("Error: parse failed\n");
		goto FAILED_RESULT;
    }

	printf("result = %0.2lf\n", result);
	


FAILED_RESULT:
	Py_DECREF(pValue);
FAILED_VALUE:
	Py_DECREF(pFunc);
FAILED_FUNC:
	Py_DECREF(pModule);
FAILED_MODULE:
	return result;
}

int main(int argc,char *argv[])
{
  double face_result = 0.0;
  face_init();
  face_result = face_category();
  face_final();

}

gcc -o face face.c -I /usr/include/python3.10 -L /usr/lib/python3.10/ -lpython3.10 -lwiringPi

./face

结果：
