在一个实施例中，针对多帧镜头特写画面中的至少一帧画面，检测至少一帧画面中出现的选手；将至少一帧画面中出现次数最多的选手确定为目标选手。可选的，通过OpenCV中的HOG描述子提取至少一帧画面中的选手。OpenCV中已有一个预先训练好的SVM系数：HOGDescriptor::getDefaultPeopleDetector()，将OpenCV中的HOGDescriptor设置为此系数，即成为一个检测器，并且，在OpenCV中将该检测器配置为多人检测detectMultiScale。将至少一帧画面传入检测器，针对每一帧画面将得到至少一个矩形数组，每个矩形数组记录了一个检测出的选手的矩形坐标，如图8所示，矩形框801对应一个矩形数组，矩形框802对应另一个矩形数组。根据矩形数组的坐标截取出选手图像。图9的(A)部分和(B)部分分别示出了截取得到的一名选手。之后对选手进行识别，将至少一帧画面中出现次数最多的选手确定为目标选手。In one embodiment, for at least one frame in the multi-frame close-up frame, a player appearing in at least one frame is detected; the player appearing most frequently in at least one frame is determined as the target player. Optionally, extract the players in at least one frame through the HOG descriptor in OpenCV. There is already a pre-trained SVM coefficient in OpenCV: HOGDescriptor::getDefaultPeopleDetector(). Set the HOGDescriptor in OpenCV to this coefficient, which becomes a detector, and configure the detector in OpenCV for multi-person detection detectMultiScale . Pass at least one frame to the detector, and for each frame, at least one rectangular array will be obtained. Each rectangular array records the rectangular coordinates of a detected player. As shown in Figure 8, the rectangular frame 801 corresponds to a rectangular array. , the rectangular frame 802 corresponds to another rectangular array. Intercept the player image according to the coordinates of the rectangular array. Parts (A) and (B) of FIG. 9 respectively show one intercepted player. The players are then identified and the player who appears the most in at least one frame is determined as the target player.
在一个实施例中，识别目标选手的可能的实施方式包括以下中的至少一种：In one embodiment, possible implementations of identifying target players include at least one of the following:
第一种可能的实施方式，在多帧镜头特写画面中的第一镜头特写画面上，基于目标选手的服装上携带的选手号码，识别目标选手。A first possible implementation is to identify the target player based on the player number carried on the clothing of the target player on the first close-up picture of the multi-frame close-up picture.
示意性的，截取得到选手图像之后，对选手图像进行裁剪。可选的，去掉图像的顶部(如占选手图像长度20％的顶部区域)，去掉图像的底部(如占选手图像长度50％的底部区域)，得到选手的上半身区域。选手的上半身区域包括选手的服装，选手服装上携带有选手号码。Schematically, after intercepting the player image, the player image is cropped. Optionally, remove the top of the image (such as the top area that accounts for 20% of the length of the player's image), and remove the bottom of the image (such as the bottom area that accounts for 50% of the length of the player's image) to obtain the player's upper body area. The player's upper body area includes the player's clothing, and the player's clothing carries the player's number.
通过识别服装上携带的选手号码，识别目标选手。可选的，通过OCR识别选手号码。示意性的，首先对选手图像进行预处理，以提升识别精度，之后使用Tesseract(一种开源ocr框架)(可选的，仅配置为识别数字模式)进行识别，以加快识别速度。在正常识别的情况下Tesseract将识别到多个数字，取置信度最高的结果作为选手图像的最终识别结果。可选的，还结合第一镜头特写画面之外的其他镜头特写画面的识别结果进行综合考虑，得到准确的选手号码。The target player is identified by identifying the player number carried on the clothing. Optionally, identify the player number through OCR. Schematically, the player images are first pre-processed to improve the recognition accuracy, and then Tesseract (an open source OCR framework) (optional, only configured to recognize digital patterns) is used for recognition to speed up the recognition. Under normal recognition conditions, Tesseract will recognize multiple numbers and take the result with the highest confidence as the final recognition result of the player's image. Optionally, the recognition results of close-ups of other shots besides the close-up of the first shot are also combined into a comprehensive consideration to obtain an accurate player number.
可选的，针对上述执行OCR前的预处理过程，预处理过程中先将选手图像进行灰度化，然后使用双边滤波降噪，保留主边缘并且模糊掉细小纹理，方便突出衣服上的数字。接着进行二值化，把选手图像的像素点的灰度值设置为0或255，使整个图像呈现出明显的黑白效果，图像二值化也能够降低噪声带来的干扰，同时消除背景干扰，从而凸显目标的轮廓，需要说明的是，二值化阈值(以此值为分界，大于则置为黑，小于或等于则置为白)的选取十分关键。可选的，通过日本学者Nobuyuki Otsu于1979年提出的一种自适应的阈值确定方法Otsu，得到二值化阈值。Otsu把图像分为前景和背景，而像素之间的方差越大，像素的相关性越低，前景和背景越分明。因此，求出选手图像中每一个像素与其周围像素的灰度值方差，得到最大方差对应的灰度值，即为二值化阈值。示意性的，图像二值化的效果如图10所示。Optionally, for the above preprocessing process before OCR is performed, the player image is first grayscaled during the preprocessing process, and then bilateral filtering is used to reduce noise, retaining the main edges and blurring out small textures to facilitate highlighting of the numbers on the clothes. Then perform binarization, and set the grayscale value of the pixels of the player's image to 0 or 255, so that the entire image presents an obvious black and white effect. Image binarization can also reduce the interference caused by noise and eliminate background interference. This highlights the outline of the target. It should be noted that the selection of the binarization threshold (this value is used as the dividing line, if it is greater than it is set to black, if it is less than or equal to it, it is set to white) is very critical. Optionally, obtain the binarized threshold through Otsu, an adaptive threshold determination method proposed by Japanese scholar Nobuyuki Otsu in 1979. Otsu divides the image into foreground and background, and the greater the variance between pixels, the lower the correlation of pixels, and the clearer the foreground and background. Therefore, the variance of the gray value of each pixel in the player image and its surrounding pixels is calculated, and the gray value corresponding to the maximum variance is obtained, which is the binarization threshold. Schematically, the effect of image binarization is shown in Figure 10.
