下载模型权重

步骤一：

我们正在使用在Caffe深度学习框架上训练的模型。Caffe模型具有2个文件–

1. .prototxt文件，指定了神经网络的体系结构–不同层的排列方式等。
2. .caffemodel文件，用于存储训练后的模型的权重

我们将使用这两个文件将网络加载到内存中。

protoFile = "model/pose_deploy_linevec.prototxt"
weightsFile = "model/pose_iter_440000.caffemodel"
net = cv2.dnn.readNetFromCaffe(protoFile, weightsFile)

步骤二：

读取图像并准备输入网络

我们使用OpenCV读取的输入帧应转换为输入Blob（例如Caffe），以便可以将其输入到网络。这是使用blobFromImage函数完成的，该函数将图像从OpenCV格式转换为Caffe blob格式。这些参数将在blobFromImage函数中提供。首先，我们将像素值标准化为（0,1）。然后，我们指定图像的尺寸。接下来，要减去的平均值为（0,0,0）。由于OpenCV和Caffe都使用BGR格式，因此无需交换R和B通道。

net = cv2.dnn.readNetFromCaffe(protoFile, weightsFile) # 读取caffe模型
inWidth = 368
inHeight = 368
inpBlob = cv2.dnn.blobFromImage(frame, 1.0 / 255, (inWidth, inHeight),
                                (0, 0, 0), swapRB=False, crop=False) #将输入图片转成相应模型识别的blob数据
net.setInput(inpBlob) # 放进网络

步骤三：

进行预测并解析关键点

一旦将图像传递到模型，就可以使用单行代码进行预测。OpenCV中DNN类的正向方法通过网络进行正向传递，这只是说它正在做出预测的另一种方式。

output = net.forward() # 向前传播，进行预测

输出为4D矩阵：

1. 第一维是图像ID（如果您将多个图像传递到网络）。
2. 第二个维度指示关键点的索引。该模型将生成所有连接在一起的置信度图和零件亲和度图。对于COCO模型，它由57个部分组成– 18个关键点置信度图+ 1个背景+ 19 * 2个部分亲和度图。同样，对于MPI，它会产生44点。我们将仅使用与关键点相对应的前几个点。
3. 第三维是输出图的高度。
4. 第四个维度是输出图的宽度。

我们检查图像中是否存在每个关键点。我们通过找到关键点的置信度图的最大值来获得关键点的位置。我们还使用阈值来减少错误检测。

H = out.shape[2]
W = out.shape[3]
# Empty list to store the detected keypoints
points = []
for i in range(len()):
    # confidence map of corresponding body's part.
    probMap = output[0, i, :, :]
 
    # Find global maxima of the probMap.
    minVal, prob, minLoc, point = cv2.minMaxLoc(probMap)
 
    # Scale the point to fit on the original image
    x = (frameWidth * point[0]) / W
    y = (frameHeight * point[1]) / H
 
    if prob > threshold :
        cv2.circle(frame, (int(x), int(y)), 15, (0, 255, 255), thickness=-1, lineType=cv.FILLED)
        cv2.putText(frame, "{}".format(i), (int(x), int(y)), cv2.FONT_HERSHEY_SIMPLEX, 1.4, (0, 0, 255), 3, lineType=cv2.LINE_AA)
 
        # Add the point to the list if the probability is greater than the threshold
        points.append((int(x), int(y)))
    else :
        points.append(None)
 
cv2.imshow("Output-Keypoints",frame)
cv2.waitKey(0)
cv2.destroyAllWindows()

由于我们事先知道了点的索引，因此只要有关键点，我们就可以通过仅加入对来绘制骨架。这是使用下面给出的代码完成的。

for pair in POSE_PAIRS:
    partA = pair[0]
    partB = pair[1]
 
    if points[partA] and points[partB]:
        cv2.line(frameCopy, points[partA], points[partB], (0, 255, 0), 3)
