Provided are a stereoscopic endoscope and endoscope measurement method； the stereoscopic endoscope comprises a light fan stereoscopic camera, a dual-instrument channel medical endoscope and operating handle (40), a medical endoscope stabilizer (46), and a medical endoscope work platform (43)； a stereoscopic image acquired by the light fan stereoscopic camera is compressed by the light fan in the horizontal direction, then the outputted image of the left and right format of the light fan has the same horizontal viewing angle, resolution, image efficiency, and half-pixel standard playback format as the conventional left and right format image； the stereoscopic endoscope combines the advantages of a light fan stereoscopic camera with a dual-instrument channel endoscope and endoscope operating handle (40) technology, thus enabling a doctor to use his or her own hands to operate two instruments at the same time to perform a minimally invasive surgery, not only greatly improving the accuracy, stability, quality, and efficiency of the surgery, but also solving the problem of the hand-eye separation of the doctor. The endoscope measurement method can be performed on a lump found during minimally invasive surgery, mucosa and diseased tissue are measured in real time, and the invention can be used in the fields of medical endoscopes, industrial endoscopes, endoscope measurement, and other stereoscopic imaging applications.L'invention concerne un endoscope stéréoscopique et un procédé de mesure d'endoscope ； l'endoscope stéréoscopique comprend une caméra stéréoscopique de ventilateur de lumière, un endoscope médical à canal d'instrument double et une poignée d'actionnement (40), un stabilisateur d'endoscope médical (46), et une plate-forme de travail d'endoscope médical (43) ； une image stéréoscopique acquise par la caméra stéréoscopique de ventilateur de lumière est comprimée par le ventilateur de lumière dans la direction horizontale, puis l'image de sortie du format gauche
