At present, advanced, fully automatic panoramic stitching function, SJCAM's 360-degree mobile panoramic shooting function, etc. As long as you hold down DC "scan" once, it will automatically stitch these pictures into Zhang Quanjing pictures. Panoramic photography is to use a camera to assemble a group of photos taken from a 360-degree scene into a picture containing all the scenes, and use special publishing software to play them online. The audience can drag the mouse to see any corner of the scene according to their own wishes. It makes people feel immersive, as if they were there.
