Problems solved by technology

[0004] Most of the imaging principles of binocular endoscopes are to synthesize images collected by two cameras. Therefore, when using binocular endoscopes, it is necessary to align the imaging areas of the two cameras first to form a complete three-dimensional image. However, The alignment effect of the current binocular endoscope is not ideal

Embodiment 1

[0052] A binocular endoscope alignment method disclosed in the embodiment of the present application is applied to an alignment device, referring to figure 2 with image 3 As shown, the alignment device includes a target plate 71 and a lens holder 72. The target plate 71 has a first calibration figure 711 and a second calibration figure 712, and the first calibration figure 711 and the second calibration figure 712 partially overlap. The lens holder 72 is used to fix the binocular endoscope 41, and when the binocular endoscope 41 is fixed on the lens holder 72, the axial direction of the binocular endoscope 41 is perpendicular to the target plate 71, and the binocular endoscope The lens of the mirror 41 is facing the target plate 71, and the target plate 71 can move with a limited length relative to the lens of the binocular endoscope 41 in the axial direction of the binocular endoscope 41.

Embodiment 2

[0100] The embodiment of the present application provides a binocular endoscope alignment system, referring to image 3 with Figure 7 As shown, the alignment system includes an alignment device and a control unit, the alignment device includes a target plate 71, and the target plate 71 has a first calibration pattern 711 and a second calibration pattern 712; the control unit is used to perform:

[0101] Adjust the vertical alignment of the first channel optical axis of the binocular endoscope 41 with the first calibration figure 711;

[0102] Adjust the second channel optical axis of the binocular endoscope 41 to vertically align with the second calibration figure 712;

[0103] Adjust the magnification of the lens where the optical axis of the first channel is consistent with the magnification of the lens where the optical axis of the second channel is located;

[0104] Wherein, the first channel optical axis is the channel optical axis of the right lens, and the second cha...

Abstract

Embodiments of the present invention provide a binocular endoscope alignment method and an alignment system, which belong to the technical field of endoscopes and are applied to an alignment device. The alignment device includes a target plate with a first calibration pattern and a second calibration pattern. Two calibration graphics; adjust the vertical alignment of the first channel optical axis of the binocular endoscope with the first calibration graphic; adjust the vertical alignment of the second channel optical axis of the binocular endoscope with the second calibration graphic; adjust the first channel optical axis The magnification of the lens where it is located is consistent with the magnification of the lens where the optical axis of the second channel is located; wherein, the optical axis of the first channel is the channel optical axis of the right lens, and the second channel optical axis is the channel optical axis of the left lens; or, The first channel optical axis is the channel optical axis of the left lens, and the second channel optical axis is the channel optical axis of the right lens. Through the binocular endoscope alignment method and alignment system provided by the embodiments of the present invention, the alignment effect of the endoscope can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of endoscopes, and in particular, to a binocular endoscope alignment device and alignment method. Background technique [0002] Endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. Endoscopes usually have image sensors, optical lenses, light source lighting, mechanical devices, etc., and can enter the stomach through the oral cavity or enter the body through other natural channels. Lesions that cannot be seen on x-rays can be seen with an endoscope. [0003] Endoscopes include monocular endoscopes and binocular endoscopes. Monocular endoscopes are endoscopes with only one camera, and binocular endoscopes are endoscopes with two cameras. Compared with monocular endoscopes, binocular endoscopes can provide a three-dimensional sense of surgical field of view and a sense of spatial depth...
