9 | 10 | - (instancetype)initWithCVPixelBuffer:(CVPixelBufferRef)pixelBuffer options:(NSDictionary *)options; 11 | ``` 12 | 在查阅一些资料后，最终通过这些函数得到了如下的效果 13 | 14 | 15 | ![face.gif](http://upload-images.jianshu.io/upload_images/2525768-c45ee7c16299c64a.gif?imageMogr2/auto-orient/strip) 16 | 对，没错，这就是通过`initWithCVPixelBuffer`函数来实现的。当然`vision`的作用远不于此，还有如下的效果 17 | 1、图像匹配（上篇文章中的效果） 18 | 2、矩形检测 19 | 3、二维码、条码检测 20 | 4、目标跟踪 21 | 5、文字检测 22 | 6、人脸检测 23 | 7、人脸面部特征检测 24 | 由于对人脸识别比较感兴趣，所以这里就主要简单了解了下人脸部分，下面就针对人脸检测和面部检测写写 25 | 26 | ##### Vision支持的图片类型 27 | 通过查看`VNRequestHandler.h`文件，我们可以看到里面的所有初始化函数，通过这些初始化函数，我们可以了解到支持的类型有： 28 | 1、`CVPixelBufferRef` 29 | 2、`CGImageRef` 30 | 3、`CIImage` 31 | 4、`NSURL` 32 | 5、`NSData` 33 | 34 | ##### Vision使用 35 | 在使用`vision`的时候，我们首先需要明确自己需要什么效果，然后根据想要的效果来选择不同的类，最后实现自己的效果 36 | 1、需要一个`RequestHandler`，在创建`RequestHandler`的时候，需要一个合适的输入源，及`图片`类型 37 | 2、需要一个`Request `，在创建`Request `的时候，也需要根据实际情况来选择，`Request `大概有如下这么些 38 | 39 | ![request.jpeg](http://upload-images.jianshu.io/upload_images/2525768-cc3cd22263666ea1.jpeg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 40 | 3、通过`requestHandler`将`request`联系起来，然后得到结果 41 | ``` 42 | [handler performRequests:@[requset] error:&error]; 43 | ``` 44 | 4、处理结果`VNObservation`，在`VNRequest`的`results`数组中，包含了`VNObservation`结果，`VNObservation`也分很多种，这和你`Request`的类型是相关联的 45 | 46 | ![Vision结果继承关系.png](http://upload-images.jianshu.io/upload_images/2525768-deced22145c609ef.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 47 | 48 | 在完成上述步骤后，我们就可以根据结果来实现一些我们想要的效果 49 | 50 | ##### 人脸矩形检测 51 | 这里我们需要用到`VNDetectFaceRectanglesRequest` 52 | ``` 53 | requset = [[VNDetectFaceRectanglesRequest alloc] initWithCompletionHandler:completionHandler]; 54 | ``` 55 | 在得到结果后，我们需要处理下坐标 56 | ``` 57 | for (VNFaceObservation *faceObservation in observations) { 58 | //boundingBox 59 | CGRect transFrame = [self convertRect:faceObservation.boundingBox imageSize:image.size]; 60 | [rects addObject:[NSValue valueWithCGRect:transFrame]]; 61 | } 62 | ``` 63 | 64 | ``` 65 | // 转换Rect 66 | - (CGRect)convertRect:(CGRect)boundingBox imageSize:(CGSize)imageSize{ 67 | CGFloat w = boundingBox.size.width * imageSize.width; 68 | CGFloat h = boundingBox.size.height * imageSize.height; 69 | CGFloat x = boundingBox.origin.x * imageSize.width; 70 | CGFloat y = imageSize.height * (1 - boundingBox.origin.y - boundingBox.size.height);//- (boundingBox.origin.y * imageSize.height) - h; 71 | return CGRectMake(x, y, w, h); 72 | } 73 | ``` 74 | 在返回结果中的`boundingBox `中的坐标，我们并不能立即使用，而是需要进行转换，因为这里是相对于`image`的一个比例，这里需要注意的是`y`坐标的转换，因为坐标系的`y`轴和`UIView`的`y`轴是相反的。 75 | 最后就是通过返回的坐标进行矩形的绘制 76 | ``` 77 | + (UIImage *)gl_drawImage:(UIImage *)image withRects:(NSArray *)rects 78 | { 79 | UIImage *newImage = nil; 80 | UIGraphicsBeginImageContextWithOptions(image.size, NO, [UIScreen mainScreen].scale); 81 | CGContextRef context = UIGraphicsGetCurrentContext(); 82 | CGContextSetLineCap(context,kCGLineCapRound); //边缘样式 83 | CGContextSetLineJoin(context, kCGLineJoinRound); 84 | CGContextSetLineWidth(context,2); //线宽 85 | CGContextSetAllowsAntialiasing(context,YES); //打开抗锯齿 86 | CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); 87 | CGContextSetFillColorWithColor(context, [UIColor clearColor].CGColor); 88 | 89 | //绘制图片 90 | [image drawInRect:CGRectMake(0, 0,image.size.width, image.size.height)]; 91 | CGContextBeginPath(context); 92 | for (int i = 0; i < rects.count; i ++) { 93 | CGRect rect = [rects[i] CGRectValue]; 94 | CGPoint sPoints[4];//坐标点 95 | sPoints[0] = CGPointMake(rect.origin.x, rect.origin.y);//坐标1 96 | sPoints[1] = CGPointMake(rect.origin.x + rect.size.width, rect.origin.y);//坐标2 97 | sPoints[2] = CGPointMake(rect.origin.x + rect.size.width, rect.origin.y + rect.size.height);//坐标3 98 | sPoints[3] = CGPointMake(rect.origin.x , rect.origin.y + rect.size.height); 99 | 100 | CGContextAddLines(context, sPoints, 4);//添加线 101 | CGContextClosePath(context); //封闭 102 | } 103 | CGContextDrawPath(context, kCGPathFillStroke); //根据坐标绘制路径 104 | 105 | newImage = UIGraphicsGetImageFromCurrentImageContext(); 106 | UIGraphicsEndImageContext(); 107 | return newImage; 108 | } 109 | ``` 110 | 效果如下 111 | 112 | 113 | ![faceRect.jpg](http://upload-images.jianshu.io/upload_images/2525768-a5febef321afbcaf.jpg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 114 | 115 | ##### 人脸特征识别 116 | 这里我们需要用到`VNDetectFaceLandmarksRequest` 117 | ``` 118 | requset = [[VNDetectFaceLandmarksRequest alloc] initWithCompletionHandler:completionHandler]; 119 | 120 | ``` 121 | 处理结果 122 | ``` 123 | for (VNFaceObservation *faceObservation in observations) { 124 | //boundingBox 125 | CGRect transFrame = [self convertRect:faceObservation.boundingBox imageSize:image.size]; 126 | [rects addObject:[NSValue valueWithCGRect:transFrame]]; 127 | } 128 | pointModel.faceRectPoints = rects; 129 | return pointModel; 130 | } 131 | 132 | - (GLDiscernPointModel *)handlerFaceLandMark:(NSArray *)observations image:(UIImage *)image 133 | { 134 | GLDiscernPointModel *pointModel = [[GLDiscernPointModel alloc] init]; 135 | NSMutableArray *rects = @[].mutableCopy; 136 | 137 | for (VNFaceObservation *faceObservation in observations) { 138 | 139 | VNFaceLandmarks2D *faceLandMarks2D = faceObservation.landmarks; 140 | 141 | [self getKeysWithClass:[VNFaceLandmarks2D class] block:^(NSString *key) { 142 | if ([key isEqualToString:@"allPoints"]) { 143 | return ; 144 | } 145 | VNFaceLandmarkRegion2D *faceLandMarkRegion2D = [faceLandMarks2D valueForKey:key]; 146 | 147 | NSMutableArray *sPoints = [[NSMutableArray alloc] initWithCapacity:faceLandMarkRegion2D.pointCount]; 148 | 149 | for (int i = 0; i < faceLandMarkRegion2D.pointCount; i ++) { 150 | CGPoint point = faceLandMarkRegion2D.normalizedPoints[i]; 151 | 152 | CGFloat rectWidth = image.size.width * faceObservation.boundingBox.size.width; 153 | CGFloat rectHeight = image.size.height * faceObservation.boundingBox.size.height; 154 | CGPoint p = CGPointMake(point.x * rectWidth + faceObservation.boundingBox.origin.x * image.size.width, faceObservation.boundingBox.origin.y * image.size.height + point.y * rectHeight); 155 | [sPoints addObject:[NSValue valueWithCGPoint:p]]; 156 | } 157 | 158 | [rects addObject:sPoints]; 159 | }]; 160 | } 161 | ``` 162 | 在这里，我们需要注意到`landmarks `这个属性，这是一个`VNFaceLandmarks2D`类型的对象，里面包含着许多面部特征的`VNFaceLandmarkRegion2D`对象，如：`faceContour`，`leftEye`，`nose`....分别表示面部轮廓、左眼、鼻子。这些对象中，又包含下面这么一个属性 163 | ``` 164 | @property (readonly, assign, nullable) const CGPoint* normalizedPoints 165 | ``` 166 | 这是一个包含该面部特征的的数组，所以我们可以通过下面的方式取出里面的坐标 167 | ``` 168 | CGPoint point = faceLandMarkRegion2D.normalizedPoints[i]; 169 | ``` 170 | 当然这里面也存在坐标的转换，见上面代码 171 | 最后也是画线，代码如下 172 | ``` 173 | + (UIImage *)gl_drawImage:(UIImage *)image faceLandMarkPoints:(NSArray *)landMarkPoints 174 | { 175 | UIImage * newImage = image; 176 | for (NSMutableArray *points in landMarkPoints) { 177 | 178 | CGPoint sPoints [points.count]; 179 | 180 | for (int i = 0;i value2) { 407 | return NSOrderedDescending; 408 | }else if (value1 == value2){ 409 | return NSOrderedSame; 410 | }else{ 411 | return NSOrderedAscending; 412 | } 413 | }]; 414 | 415 | NSArray *sortPointYs = [pointYs sortedArrayWithOptions:NSSortStable usingComparator: 416 | ^NSComparisonResult(id _Nonnull obj1, id _Nonnull obj2) { 417 | int value1 = [obj1 floatValue]; 418 | int value2 = [obj2 floatValue]; 419 | if (value1 > value2) { 420 | return NSOrderedDescending; 421 | }else if (value1 == value2){ 422 | return NSOrderedSame; 423 | }else{ 424 | return NSOrderedAscending; 425 | } 426 | }]; 427 | 428 | UIImage *image =[UIImage imageNamed:@"eyes"]; 429 | CGFloat imageWidth = [sortPointXs.lastObject floatValue] - [sortPointXs.firstObject floatValue] + 40; 430 | CGFloat imageHeight = (imageWidth * image.size.height)/image.size.width; 431 | 432 | self.glassesImageView.frame = CGRectMake([sortPointXs.firstObject floatValue]-20, [sortPointYs.firstObject floatValue]-5, imageWidth, imageHeight); 433 | }); 434 | } 435 | }]; 436 | ``` 437 | 由于时间关系，代码有点乱，将就将就 438 | 439 | 先说说思路，我是想动态添加一个眼镜的，所以我必须先得到两个眼睛的位置，然后在计算出两个眼睛的宽高，最后适当的调整眼镜的大小，再动态的添加上去 440 | 441 | 这里必须要说的一个问题，就是我在实现过程中遇到的---`坐标` 442 | 443 | 首先是`y`坐标，如果还是按照静态图片的那种获取方式，那么得到的结果将会是完全相反的。 444 | ``` 445 | faceObservation.boundingBox.origin.y * image.size.height + point.y * rectHeight 446 | ``` 447 | 这里我做了一个假设，估计是由于摄像机成像的原因造成的，所以必须反其道而行，于是我如下改造了下 448 | ``` 449 | CGFloat boundingBoxY = self.view.bounds.size.height * (1 - faceObservation.boundingBox.origin.y - faceObservation.boundingBox.size.height); 450 | 451 | p = CGPointMake(point.x * rectWidth + faceObservation.boundingBox.origin.x * self.view.bounds.size.width, boundingBoxY + (1-point.y) * rectHeight); 452 | ``` 453 | 从中可以看到，所有的`point.y`都用`1`减去了，这个试验的过程有点恼火，我还没怎么相通，若有知道的，希望可以告诉我下，当然我也会再研究研究。 454 | 再说完`y`坐标后，就是`x`坐标了，`x`坐标在`前置摄像头`的时候一切正常，然而在切换成`后置摄像头`的时候，又反了。😔！心累啊，所以没办法，我就只要加判断，然后进行测试，有了如下代码 455 | ``` 456 | CGFloat boundingX = self.view.frame.size.width - faceObservation.boundingBox.origin.x * self.view.bounds.size.width - rectWidth; 457 | ``` 458 | 最后终于大功告成！ 459 | 效果就是文章最顶的那个效果 460 | 461 | ##### 注意 462 | 1、在使用过程中，我发现当检测图片的时候内存和`cpu`的消耗还是很高的，比如我的`5s`就成功的崩溃过..... 463 | 2、图片方向是有要求的.... 464 | ``` 465 | - (instancetype)initWithCVPixelBuffer:(CVPixelBufferRef)pixelBuffer options:(NSDictionary *)options; 466 | 467 | /*! 468 | @brief initWithCVPixelBuffer:options creates a VNImageRequestHandler to be used for performing requests against the image passed in as buffer. 469 | 470 | @param pixelBuffer A CVPixelBuffer containing the image to be used for performing the requests. The content of the buffer cannot be modified for the lifetime of the VNImageRequestHandler. 471 | @param orientation The orientation of the image/buffer based on the EXIF specification. For details see kCGImagePropertyOrientation. The value has to be an integer from 1 to 8. This superceeds every other orientation information. 472 | @param options A dictionary with options specifying auxilary information for the buffer/image like VNImageOptionCameraIntrinsics 473 | */ 474 | - (instancetype)initWithCVPixelBuffer:(CVPixelBufferRef)pixelBuffer orientation:(CGImagePropertyOrientation)orientation options:(NSDictionary *)options; 475 | 476 | ``` 477 | 通过对比上面两个函数，我们可以发现，多了一个`CGImagePropertyOrientation `类型的参数，没错，这就是指定传入图片的方向，如果指定了方向，而图片方向却不一致，那么恭喜你，检测不出来....这里我用的都是第一个方法，及没有参数，好像默认是`up`的。 478 | 479 | ##### 最后 480 | 还是附上[Demo](https://github.com/gao211326/VisionDemo)，如果觉得还行的话，欢迎大家给个`star`！有什么问题，可以多多沟通 481 | --------------------------------------------------------------------------------
