The invention discloses a method for rapidly visualizing multi-scale image segmentation results for large images, which comprises the following steps: in the process of carrying out region segmentation and storage on an original image, segmenting the original image into a plurality of regions, identifying pixels in each region by using corresponding ID (identification) values so as to obtain an object ID image, and establishing an image pyramid; when a user browses, pre-loading images at the lower-resolution layer of the image pyramid; according to the operation of the user, judging the spatial resolution after the operation of the user is completed, determining the data of selected and extracted corresponding layers of the image pyramid, and according to the current view range, reading corresponding pixels in corresponding layers of the image pyramid; in the process of rendering edges of segmentation results, traversing each pixel, and judging whether the pixel is the boundary by using the most adjacent sampling; and when the user clicks some region in the current view range by using a mouse, judging the ID value of a pixel clicked by the mouse firstly, and then carrying out highlighting on the pixels with a same ID value.
