Trademark similarity evaluation method and device

The invention relates to a trademark similarity evaluation method and device, and relates to the technical field of image recognition, and the method comprises the following steps: a server extracts a first feature vector in a first trademark image and a second feature vector in a second trademark image based on a NetVLAD model; obtaining an image matching degree between the first trademark image and the second trademark image based on the first feature vector and the second feature vector; the similarity between the first trademark image and the second trademark image is obtained on the basis of the image matching degree and the character similarity, the image matching degree and the character similarity are fused through the method, and the similarity between the first trademark image and the second trademark image can be evaluated more accurately. 本申请涉及一种商标相似度评估方法以及装置，涉及图像识别技术领域，该方法包括以下步骤：服务器基于NetVLAD模型，分别提取第一商标图像中的第一特征向量以及第二商标图像中的第二特征向量；基于第一特征向量以及第二特征向量，获取第一商标图像与第二商标图像之间的图像匹配度；再基于图像匹配度以及文字相似度，获取第一商标图像与第二商
