Method and apparatus for generating dental panoramic image, and panoramic camera for photographing teeth

An apparatus for generating a dental panoramic image, comprising:

• a processor;
• memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• determine a frame frequency of a reference detector, and determine a frame frequency of a photographing detector according to the frame frequency of the reference detector;
• process a photograph of teeth of a patient according to the frame frequency of the photographing detector to generate a plurality of images;
• perform a shift and superposition on the plurality of images to generate a first panoramic image;
• acquire a fuzzy region in the first panoramic image;
• and
• perform a frame frequency adjustment on each row in the fuzzy region to generate a clear image, and fuse the clear image and the first panoramic image to generate a second panoramic image.
