Similarity calculation optimization method, similarity calculation optimization device and storage medium

The invention discloses a similarity calculation optimization method, a similarity calculation optimization device and a storage medium, and the method comprises the steps: obtaining a to-be-matched image, wherein the to-be-matched image comprises a plurality of pixel points; obtaining the gradient magnitude of each pixel point; and carrying out similarity calculation on the pixel points of which the gradient amplitudes are greater than or equal to a preset amplitude threshold and the pixel points in the template image to obtain the similarity between the to-be-matched image and the template image. Through the mode, the pixel points in the to-be-matched image can be screened based on the gradient magnitude of the pixel points, so that the calculation amount of similarity calculation is reduced, and the matching efficiency of template matching is improved on the premise of ensuring the matching quality. 本申请公开了一种相似度计算优化方法、相似度计算优化装置以及存储介质，该相似度计算优化方法包括：获取待匹配图像，待匹配图像包括若干像素点；获取每一像素点的梯度幅值；对梯度幅值大于等于预设幅值阈值的像素点与模板图像中像素
