摘要： A medical endoscope system and an operation method of a medical endoscope system with which a distance to a subject can be more accurately perceived are provided.
A processor device of an endoscope system functions as a pseudodistance data generation unit (74), an actual measurement distance data acquisition unit (76), and a distance data correction unit (78). The pseudodistance data generation unit (74) generates pseudodistance data obtained by estimating a distance to a subject for a plurality of locations within an imaging range. The actual measurement distance data acquisition unit (76) acquires actual measurement distance data obtained by measuring the distance to the subject for at least one location within the imaging range. The distance data correction unit (78) corrects the pseudodistance data using the actual measurement distance data.

摘要： A surgical visualization system including a display screen, a first light emitter, a second light emitter, an image sensor, and a control circuit is disclosed. The first light emitter is configured to emit a plurality of spectral light waves configured to penetrate an organ. The second light emitter is configured to emit a structured light pattern onto a surface of the organ. The image sensor is configured to detect at least one of a reflected plurality of spectral light waves and a reflected structured light pattern. The control circuit is in signal communication with the image sensor, the first light emitter, the second light emitter, and the display screen, and is configured to receive pre-operative imaging data associated with the organ, receive first intraoperative imaging data indicative of the structured light pattern on the surface of the organ, generate a three-dimensional digital representation of the organ based on the pre-operative imaging data and the first intraoperative imaging data, display the three-dimensional digital representation of the organ on the display screen, receive second intraoperative imaging data indicative of the plurality of spectral light waves penetrating the organ, intraoperatively identify a structure below the surface of the organ based on the second intraoperative imaging data, generate a three-dimensional digital representation of the structure below the surface of the organ, and display the three-dimensional digital representation of the structure below the surface with the three-dimensional digital representation of the organ on the display screen.

摘要： Disclosed is a method of calibrating a camera and a projector used in an intraoral scanner. The method of calibrating an intraoral scanner comprises the steps of: irradiating an illumination light of a third color by using a projector (12) onto a first calibration plate (100) having a background (110) of a first color and patterns (120) of a second color different from the first color, which are arranged at predetermined intervals within the background (110); obtaining an image (130) of the patterns (120) with an increased contrast by photographing the first calibration plate (100) with a camera; calibrating the camera by comparing the image (130) of the patterns (120) with actual positions of the patterns (120) formed on the calibration plate (100); irradiating the first calibration plate (100) with a patterned light having a predetermined pattern of a fourth color by using the projector (12); obtaining an image (150) of a pattern (152) formed by the patterned light of the projector (12) by photographing the first calibration plate (100) with the camera; and calibrating the projector (12) by comparing the pattern image (152) with a target irradiation position of a pattern irradiated by the projector (12), wherein the first color and the second color are set such that a contrast between the background (110) and the patterns (120) increases when the first calibration plate (100) is illuminated with the illumination light of the third color, and the predetermined pattern of the fourth color is set so as to cover the patterns (120) formed on the first calibration plate (100) and so that the contrast between the background (110) and the patterns (120) formed on the first calibration plate (100) is reduced.
