The present invention provides a sky filter method for panoramic images and a portable terminal. The method comprises: obtaining several panoramic images containing sky regions as a data set, and marking a sky region and a ground region of each of the panoramic images in the data set, so as to obtain a marked mask image corresponding to each of the panoramic images in the data set, and obtain a panoramic template image of sky; respectively extracting, according to the marked mask images, features of the sky region and the ground region of each of the panoramic images in the data set, and marking a positive sample and a negative sample of each of the panoramic images; sequentially inputting the positive sample and the negative sample of each of the panoramic images in the data set to a support-vector machine (SVM) for training, so as to obtain a model; extracting and testing the features of the panoramic images, and inputting the same to the model, so as to obtain an initial mask image in which sky pixels and ground pixels are marked; removing a misclassified pixel and a misclassified region in the initial mask image, so as to obtain a corresponding accurate mask image; and for the accurate mask image, using a multi-resolution fusion algorithm to fuse the panoramic template image of sky and a test panoramic image, so as to achieve a sky filter effect.
