Image coarse positioning method and device and computer readable storage medium

The invention discloses an image coarse positioning method and device and a computer readable storage medium, and belongs to the technical field of image processing. The method comprises the following steps: acquiring key points representing a local feature region in a to-be-processed image; determining a plurality of candidate templates corresponding to the to-be-processed image according to a matching result between the key points and a preset template; and according to the position code of the to-be-processed image and the position code label of each candidate template, screening out a target template from the candidate templates, and taking the target template as a coarse positioning result of the to-be-processed image. According to the method, key point matching and position code matching are combined, and the accuracy of a coarse positioning result is improved. 本发明公开了一种图像粗定位方法、设备及计算机可读存储介质，属于图像处理技术领域。该方法包括：获取待处理图像中表征局部特征区域的关键点；根据所述关键点与预置模板之间的匹配结果，确定所述待处理图像对应的若干候选模板；根据所述待处理图像的位置编码，以及各所述候选模板的位置编码标签，从所述候选模
