Eclipse工程 2. SDK函数说明 SDK需要授权后才能使用，SDK的授权以一个机器一个码为主 (1)int ZY_GetDevicesSerialNumber(ByteBuffer EncryptionSerial, ByteBuffer mac, ByteBuffer cardstype);//获取设备机器信息并转成机器码，提供给中运科技获取授权码，该函数只需要调用一次，不需要每次都重复调用，用于SDK授权专用 /*The ZY_GetDevicesSerialNumber function will get the PC info and turn to EncryptionSerial,the EncryptionSerial must be given back to ZYTECHNOLOGY to get the decryptSerial code Parameters: EncryptionSerial[output],new [128] char* in mac[output],new [128] char* in cardstype[output] new [128] char* in error code: FACE_ERROR_SERAIL_P -401 FACE_SUCESS 0 Remarks: This function only can be called one time at program first used.*/ (2)int ZY_FaceSDKInit(int nChannelNums, ByteBuffer decryptSerial);//初始化函数，可以一次性初始化多路检测提取，参数1为需要初始化的路数，一般大于1小于8，在程序开始的时候调用，只需要调用一次 /*The ZY_FaceSDKInit function will initialize the algorithm engine module must be given back to ZYTECHNOLOGY to get the decryptSerial code Parameters: nChannelNums[intput],algorithm channel nums,for multi-thread mode,one thread uses one channel decryptSerial[intput],the decryptSerial code get from ZYTECHNOLOGY error code: FACE_SUCESS 0 FACE_ERROR_INITFAILED -1 FACE_ERROR_MAXCHANNEL -6 FACE_REPEAT_INITFAILED -9 FACE_ERROR_SERAIL_P -401 FACE_ERROR_DECRYPT_P -402 FACE_ERROR_TIMEOUT -403 FACE_ERROR_LOCAL_DECRYPT_P -404 FACE_ERROR_LOCAL_DECRYPT_FILE_P -405 FACE_ERROR_COMPARE_DECRYPT_FILE_P -406 FACE_ERROR_NO_DECRYPT_P -407 Remarks: This function only can be called one time at program initialization.*/ (3)int ZY_DetectAndExtract(ByteBuffer pdata, int width, int height, int channel, ByteBuffer pFea);//人脸特征提取函数，需要输入BGR图像数据，输出长度为512的byte类型特征码 /*The ZY_DetectAndExtract function execute face detection and get face feature. Parameters: pdata[input],image data buffer,RGB24 format. width[input],image width. height[input],image height. channel[input],bits per pixel(24-RGB24 image),must be 24 pFea[output],the face feature.. Return Values: If the function succeeds, the return value is FACE_SUCESS If the function fails, the return value is negative. error code: FACE_SUCESS 0 FACE_ERROR_INITFAILED -1 FACE_ERROR_MAXCHANNEL -6 FACE_REPEAT_INITFAILED -9 FACE_ERROR_SERAIL_P -401 FACE_ERROR_DECRYPT_P -402 FACE_ERROR_TIMEOUT -403 FACE_ERROR_LOCAL_DECRYPT_P -404 FACE_ERROR_LOCAL_DECRYPT_FILE_P -405 FACE_ERROR_COMPARE_DECRYPT_FILE_P -406 FACE_ERROR_NO_DECRYPT_P -407 Remarks: 1.image data buffer(pImage) size must be nWidth*(bpp/8)*nHeight. 2.pFea must be allocated by caller,the memory size is FATURE_SIZE 3.image data have only have one face in*/ (4)int ZY_FaceSDKRelease()//释放函数，与初始化函数一杨，只需要调用一次，在程序退出时候调用 /* The ZY_FaceSDKRelease function will release the algorithm engine module Parameters: No parameter. Return Values: No return value. Remarks: This function only can be called one time at program exit.*/ 3. 调用顺序 (1) ZY_GetDevicesSerialNumber 获取机器码 提供给中运科技以获取授权码，授权码为一个机器一个码 (2) ZY_FaceSDKInit 程序初始化，包括SDK授权以及人脸SDK功能初始化 (3) ZY_DetectAndExtract 初始化成功后获取人脸特征 (4) ZY_FaceSDKRelease() 释放资源，在程序退出时候调用
