Abstract
In an endoscope system, an insertion amount of an insertion unit is detected based on camera images captured by two cameras provided to a mouthpiece. Then, past images of a predetermined range corresponding to the detected insertion amount are acquired from a past image storage unit. A current image is compared with each of the acquired past images to calculate similarity between the current image and each of the past images. A body part captured in the past image having the highest similarity with the current image is determined to be the body part captured in the current image.
Claims10
A body part identification device used for an endoscope, the endoscope inserting an insertion section into a body cavity of a patient and capturing an image of the body cavity, a distal portion of the insertion section incorporating an imaging unit, the body part identification device being configured to identify an imaged body part in a current image currently being captured by the imaging unit, the body part identification device comprising:
- a processor configured to perform functions of:
- detecting an insertion amount of the insertion section inserted into the body cavity;
- acquiring the current image;
- acquiring at least one past image from a past image storage unit based on the insertion amount detected by the insertion amount detecting function, the past image storage unit storing the past images captured in at least one past endoscopic examination;
- and
- identifying the imaged body part in the current image through comparing the past image acquired by the past image acquiring function with the current image and determining the past image similar to the current image,
- wherein the processor is configured to further perform the functions of:
- detecting a bend amount of the insertion section;
- and
- detecting a rotation amount of the insertion section about an axis of the insertion section, and
- wherein the past image acquiring function acquires the past image based on the insertion amount, the bend amount, and the rotation amount.
A body part identification method used for an endoscope, the endoscope inserting an insertion section into a body cavity of a patient and capturing an image of the body cavity, a distal portion of the insertion section incorporating an imaging unit, the body part identification method identifying an imaged body part in a current image currently being captured by the imaging unit, the body part identification method allowing a body part identification device to perform the steps of:
- detecting an insertion amount of the insertion section inserted into the body cavity;
- acquiring the current image;
- acquiring at least one past image from a past image storage unit based on the insertion amount, the past image storage unit storing the past images captured in at least one past endoscopic examination;
- and
- identifying the imaged body part in the current image through comparing the acquired past image with the current image and determining the past image similar to the current image,
- detecting a bend amount of the insertion section;
- and
- detecting a rotation amount of the insertion section about an axis of the insertion section, and
- wherein the past image acquiring function acquires the past image based on the insertion amount, the bend amount, and the rotation amount.
A non-transitory computer-readable medium having instructions stored therein, which, when executed by a computer, cause the computer to perform operations for identifying an imaged body part in a current image currently being captured by an imaging unit, the imaging unit being incorporated in a distal portion of an insertion section of an endoscope, the endoscope inserting the insertion section into a body cavity of a patient and capturing an image of the body cavity, the operations comprising:
- detecting an insertion amount of the insertion section inserted into the body cavity;
- acquiring the current image;
- acquiring at least one past image from a past image storage unit based on the insertion amount, the past image storage unit storing the past images captured in at least one past endoscopic examination;
- and
- identifying the imaged body part in the current image through comparing the acquired past image with the current image and determining the past image similar to the current image,
- detecting a bend amount of the insertion section;
- and
- detecting a rotation amount of the insertion section about an axis of the insertion section, and
- wherein the past image acquiring function acquires the past image based on the insertion amount, the bend amount, and the rotation amount.
