可选的，上述将人物图像与图像模板进行比对的实现方式具体可以为：Optionally, the implementation manner of comparing the image of the person with the image template may be:
提取人物图像中每个像素点的灰度值，提取斑点灰度值范围内的像素点及其坐标，斑点灰度值范围内的像素点即斑点，如相邻斑点之间的距离小于设定距离，则将该相邻斑点划分为一个斑区域，遍历所有的斑点区分出所有的斑区域；将所有的斑区域显示在人物图像的对应位置，提取图像模板中的所有斑区域，以双眼中心点为原点，360°均匀放出多条射线穿过所有斑区域，依据多条射线与所有斑区域边缘的交点获取每个斑区域边缘与中心点的距离；获取人物图像中每个斑区域边缘与中心点的距离，将图像模板中每个斑区域边缘与中心点的距离逐个与人物图像中每个斑区域边缘与中心点的距离进行比对，如图像模板中有设定数量个斑区域不存在人物图像中，则确定比对不相似，否则确定相似。Extracting the gray value of each pixel in the image of the person, extracting the pixel point and its coordinates within the range of the gray value of the spot, and the pixel within the range of the gray value of the spot is the spot, such as the distance between the adjacent spots is less than the setting The distance is divided into a spot area, and all the spots are traversed to distinguish all the spot areas; all the spot areas are displayed at corresponding positions of the person image, and all the spot areas in the image template are extracted to the center of the eyes. The point is the origin, 360° uniformly emits a plurality of rays through all the plaque regions, and the distance between the edge of each plaque region and the center point is obtained according to the intersection of the plurality of ray and the edge of all the plaque regions; and the edge of each plaque region in the image of the person is obtained The distance between the center points and the distance between the edge of each spot in the image template and the center point are compared with the distance between the edge of each spot in the image and the center point. For example, there is a set number of spot areas in the image template. In the presence of a character image, it is determined that the alignment is not similar, otherwise the similarity is determined.
此设计主要是通过斑点区域来进行人物图像的识别，因为对于人像来说，一般都有斑点，并且斑点的灰度值基本处于一个范围内，比较容易区分出灰度值，则通过对比所有斑点的问题就可以实现人物图像的区分，因为对于每个人来说，其斑点肯定不可能一致，所有其也可以明显的进行区分，另外，这里以双眼中心点作为基准点也是为了避免人的长胖长瘦所引起的对比对结果的影响，以双眼中心点为基准点能避免其产生的影响，所以上述方法具有比对准确度高的优点。This design mainly uses the spot area to identify the image of the person, because for the portrait, there are generally spots, and the gray value of the spot is basically in a range, and it is easier to distinguish the gray value, then all the spots are compared. The problem can be achieved by distinguishing the images of the characters, because for each person, the spots must not be consistent, and all of them can be clearly distinguished. In addition, the central point of the eyes is used as a reference point to avoid people's gain. The effect of the contrast caused by long thinness on the result can be avoided by taking the center point of both eyes as the reference point, so the above method has the advantage of high accuracy.
