The application discloses a solution method and device for direction perception disorder caused by rotating a mirror, and solves the problem that it is difficult to determine the adjacent tissue structure outside the part after endoscopic examination is rotated in similar upper gastrointestinal tract wall lesions. The application comprises the following steps: acquiring the pose information of an endoscope in an electromagnetic navigation system of a lumen target position and corresponding lumen image as a reference pose; acquiring the trajectory pose of the endoscope after adjusting the field of view in the electromagnetic navigation system and corresponding lumen image, and determining the Euler angle of each trajectory point according to the trajectory pose; acquiring the trajectory pose of the endoscope after adjusting the field of view in the electromagnetic navigation system and corresponding lumen image, and determining the Euler angle of each trajectory point according to the trajectory pose; and reconstructing the lumen and the adjacent tissue according to the lumen image three-dimensionally, and obtaining the rotated lumen and the adjacent tissue according to the rotating angle and the corresponding lumen image. Through the application, the adjacent tissue outside the endoscope can be clearly known after the endoscope is rotated to the best field of view.
