The embodiment of the invention provides a consistency detection method and device, terminal equipment and a computer readable storage medium, and relates to the field of data processing. The consistency detection method comprises the following steps: extracting keywords in a text and sub-images corresponding to each object in an image; carrying out reconstruction on the sub-images of which the total number of pixels is smaller than a first preset number to obtain reconstructed sub-images, wherein the total number of pixels of the reconstructed sub-images is greater than or equal to the firstpreset number; identifying the sub-images with the total number of pixels greater than or equal to the first preset number and the reconstructed sub-images to obtain object types corresponding to theobjects in the image; and performing consistency detection on the object category and the keyword to obtain a consistency detection result. The resolution of the reconstructed sub-image is higher thanthat of the sub-image before reconstruction, so that the type of the object corresponding to each object in the image is more accurate, and the accuracy of consistency detection can be improved.
