Disclosed are a panoramic video rendering method capable of automatically adjusting an angle of view, and a storage medium and a computer device, wherein same are applied to the field of panoramic video processing. The method comprises: acquiring the amount of rotation of a panoramic camera relative to a world coordinate system when the current video frame is photographed, and multiple paths of fisheye images corresponding to the current video frame and a previous video frame; respectively extracting corners of the multiple paths of fisheye images corresponding to the previous video frame, acquiring a corner sequence to be tracked, and tracking said corner sequence to acquire a matching point pair to be tracked; and optimizing, according to the matching point pair, the displacement of the current video frame relative to the previous video frame, calculating a rotation matrix of the current virtual camera by taking the optimized displacement as an advancing direction of a virtual camera, and performing transition rendering on the current video frame by using the amount of rotation and the rotation matrix. By means of the method, a motion direction of a panoramic camera can be automatically calculated, an angle of view of a panoramic video can be automatically adjusted according to the motion direction, and a video shot of the panoramic camera is kept always in an advancing direction of the panoramic camera.
