Embodiment Construction

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0039] figure 1 Schematic diagram of the principle of measuring the size of endoscopic lesions by the ruler method.

[0040] exist figure 1 Among them, the lesion 1 to be measured is imaged on the target surface of the camera sensor 3 through the camera lens 2, and the measuring scale 4 is penetrated into the lesion area to be measured through the endoscope forceps hole, and is simultaneously imaged on the target surface of the camera sensor 3 through the camera lens 2 , the operating doctor adjusts the opening of the ruler according to the image of the target surface of the sensor 3 displayed on the monitor, so that the port is located at the edge of the lesion area, and then reads the reading of the scale to calculate the size of the lesion.

[0041] figure 1 The positions of two measuring scales 4 are marked in , the position A is on the lesion area, and...

Abstract

The invention provides a method and a device for quantitatively measuring the size of a focus through an electronic endoscope. A beacon light projection method is adopted, and non-contact quantitative measurement on the size of the focus is achieved through image analysis and calculation of an electronic endoscope image processing device. Both the discomfort of a patient is not increased, and the workload of operation, reading and the like of a doctor is not increased.

Description

technical field [0001] The invention relates to the technical field of medical electronic endoscope imaging inspection, in particular to a method and device for non-contact quantitative measurement of lesion size according to electronic endoscope images, and an electronic endoscope system using the quantitative measurement device. Background technique [0002] Electronic endoscope is one of the indispensable instruments in modern medical examination. It is directly used to observe the tissue morphology of internal organs of the human body, which is of great significance for the early diagnosis of cancer. [0003] The electronic endoscope camera lens is a pan-focus optical system with a large imaging depth of field, generally up to 5mm~100mm. Its advantage is that it can clearly observe the lesion image within a large range from the camera objective lens. Large and small lesions are at different distances from the objective lens, and the size of the lesion image displayed on ...
