A method and an electronic apparatus for stitching a three-dimensional spherical panorama are provided. The method includes: obtaining a first image and a second image; projecting the first and seconds image onto a virtual spherical plane to form a first equirectangular panorama and a second equirectangular panorama; duplicating the first equirectangular panorama to generate a third equirectangular panorama, and duplicating the second equirectangular panorama to generate a fourth equirectangular panorama; performing image enhancement on the third and fourth equirectangular panoramas to generate a first enhanced equirectangular panorama and a second enhanced equirectangular panorama; calculating an optical flow for the first and second enhanced equirectangular panoramas; generating the three-dimensional spherical panorama according to the first and second equirectangular panoramas and the optical flow. The method and the electronic apparatus for stitching the three-dimensional spherical panorama may stitch, into the three-dimensional spherical panorama, images output by a radially designed panoramic camera.

An electronic device having a neural network framework for estimating optical flow is provided. The electronic device is connected to an image acquiring unit, which acquires images to be analyzed. The electronic device includes a storage unit, a feature extraction unit, an optical flow estimation unit and a refining unit. The storage unit stores a feature extraction module. The feature extraction unit is connected to the image acquiring unit and the storage unit. The optical flow estimation unit is connected to the feature extraction unit to generate an estimated optical flow. The refining unit is connected to the optical flow estimation unit to input the estimated optical flow to a refining module to obtain an estimated optical flow result. A method for estimating optical flow is also provided to reduce the number of training parameters required for estimating optical flow, thereby reducing a training time and improving training stability.
