The field diaphragm of the 3D endoscope in the prior art is generally arranged inside an imaging lens group, the focus adjustment is carried out based on a focusing lens arranged at the rear side of the imaging lens group, imaging is carried out by a photosensitive device arranged at the rear side of the focusing lens, and after the field diaphragm intercepts light, focusing treatment based on the focusing lens can cause the light to generate diffusion in different degrees, so that the position area of the light projected on the photosensitive device is not fixed, and the edge blurring problem is caused.
In a first aspect, as shown in fig. 1, an adjustable imaging assembly of a 3D endoscope in some embodiments of the present application for endoscopic imaging, the adjustable imaging assembly comprising:
a housing 1;
an imaging device 2 slidably mounted in the housing 1;
an adjusting mechanism 3 mounted on the housing 1 for driving the imaging device 2 to slide in the housing 1;
the imaging device 2 comprises a binocular field diaphragm 21, an ocular lens group 22 and a photosensitive device 23 which are relatively fixed in position distance and are arranged in sequence.
Specifically, the imaging device 2 can slide linearly in the housing 1 based on the driving action of the adjusting mechanism 3, i.e., the visual field range of the light collected by the 3D endoscope received by the imaging device 2 can be changed, i.e., the magnification of the binocular image information finally acquired by the photosensitive device 23 is changed, i.e., the imaging focal length is changed.
More specifically, since the imaging device 2 adopts the adjusting mechanism 3 to adjust the position to achieve image magnification zooming, the whole 3D endoscope can remove the focusing lens structure originally used for focusing, and can change the binocular field diaphragm 21 originally arranged in the lens group into an external setting, i.e., on the front side of the eyepiece lens group 22 away from the light sensing device 23.
More specifically, the positions of the binocular field diaphragm 21, the eyepiece lens group 22 and the photosensitive device 23 are relatively fixed, that is, a fixed optical path distance is formed between the binocular field diaphragm 21 and the photosensitive device 23, and the binocular image information formed on the photosensitive device 23 is formed on the basis that light collected by the 3D endoscope passes through the binocular field diaphragm 21 and is refracted by the eyepiece lens group 22 and then falls on the photosensitive device 23, so that no matter the imaging device 2 is adjusted to any position under the driving action of the adjusting mechanism 3, the area range of the light falling on the photosensitive device 23 is fixed, so that the photosensitive device 23 can always obtain the binocular image information with a fixed size, and the position change of the imaging device 2 only changes the zoom ratio of the binocular image information to the image object; on this basis, binocular field of vision diaphragm 21 acts as the field of vision limiting device of image device 2, can intercept the light that is used for forming beyond the binocular image information, simultaneously because binocular field of vision diaphragm 21 sets up the front side at eyepiece battery of lens 22, the light through binocular field of vision diaphragm 21 is the light based on the direct collection of 3D endoscope, this light is not through traditional focusing lens structure carrying out focusing process, after binocular field of vision diaphragm 21 intercepts this light, can form clear visible binocular image information in edge on sensitization device 23, effectively improve the utilization ratio of light, and avoid the binocular image information who forms to have blurring edge and arouse too much uselessness and influence subsequent image processing.
More specifically, in the stage of designing the adjustable imaging assembly of the 3D endoscope in the embodiment of the present application, the shape of the binocular image information formed by the photosensitive device 23 can be changed by adjusting the shape structure of the binocular field diaphragm 21, the size of the binocular image information formed by the photosensitive device 23 can be changed by changing the distance between the binocular field diaphragm 21 and the eyepiece lens group 22 and the size of the binocular field diaphragm 21, and the above-mentioned design contents about the binocular image information can be designed and adjusted according to the use requirements of the 3D endoscope, so that the adjustable imaging assembly of the 3D endoscope in the embodiment of the present application is suitable for different use occasions.
The adjustable imaging assembly of the 3D endoscope provided by the embodiment of the application cancels the focusing lens structure of the traditional 3D endoscope, the position of the imaging device 2 is changed through the adjusting mechanism 3, so that the light range received by the photosensitive device 23 can be changed to realize the magnification scaling of the formed binocular image information, namely, the image focusing processing is realized, meanwhile, the positions of the binocular field diaphragm 21, the eyepiece lens group 22 and the photosensitive device 23 are relatively fixed in distance, and the binocular field diaphragm 21 is arranged in the front position, so that the imaging device 2 can form the binocular image information with clear edges on the photosensitive device 23 under different imaging focal lengths, so that the two image edge parts of the binocular image information are prevented from interfering with each other, and the subsequent binocular image information is cut and combined to form the 3D image information.
In some preferred embodiments, the binocular field stop 21 includes a left field stop and a right field stop, which are square stops of uniform size.
Specifically, the binocular image information formed on the photosensitive device 23 is a view field image used for establishing 3D image information, and it needs to acquire image information respectively matched with the left eye and the right eye, so that the adjustable imaging component of the 3D endoscope of the embodiment of the present application needs to intercept light through the binocular view field diaphragm 21 to form two light view field channels in a partitioned manner, that is, intercept light through the left view field diaphragm and the right view field diaphragm respectively, so that the image information respectively matched with the left eye and the right eye is formed on the photosensitive device 23.
More specifically, in other embodiments, the left field diaphragm and the right field diaphragm may also be one of a rectangular diaphragm, a circular diaphragm, and an elliptical diaphragm with the same size, and may be selected according to morphological characteristics of the finally-to-be-acquired 3D image information.

In some preferred embodiments, the eyepiece lens group 22 is located at an intermediate position between the binocular field stop 21 and the light sensing device 23.
Specifically, the design position of the eyepiece lens group 22 may change the proportional relationship between the size of the field of view of the binocular field of view diaphragm 21 and the size of the binocular image information formed on the photosensitive device 23, if the eyepiece lens group 22 is designed to be closer to the binocular field of view diaphragm 21, the size of the binocular image information may be larger, but edge distortion of the binocular image information may be caused, if the eyepiece lens group 22 is designed to be closer to the photosensitive device 23, the size of the binocular image information may be smaller, resulting in a larger image resolution, therefore, the eyepiece lens group 22 is disposed at the middle position between the binocular field of view diaphragm 21 and the photosensitive device 23 in the embodiment of the present application, such that the size of the binocular image information is approximately consistent with the size of the field of view of the binocular field of view diaphragm 21, so as to form high-quality binocular image information.
More specifically, since the binocular vision diaphragm 21 has clearly distinguished left and right vision diaphragms, the positioning of the eyepiece lens group 22 at an intermediate position between the binocular vision diaphragm 21 and the photo-sensing device 23 necessarily enables two pieces of clearly distinguished image information to be formed on the photo-sensing device 23, i.e., the two pieces of image information are made to have a boundary therebetween that coincides with that between the left and right vision diaphragms, so as to more effectively avoid the adjacent edge portions of the two images of the binocular image information from interfering with each other.
