[0039] As shown in FIG. 5, the working process of image acquisition and visual enhancement is as follows:

[0040] the object light reflected by the real scene passes through the camera lens of the image acquisition device, and enters the image sensor device under the action of the object imaging of the camera lens; the image sensor imports the collected image into the image enhancement unit, and enters the image storage device or the image information transmission device 13 after the enhancement effect of the image enhancement unit; the enhanced image obtained by the image enhancement unit is imported into the near-to-eye display screen; after the enhanced image is displayed by the near-to-eye optical system, using the diopter adjustment device located between the near-to-eye display screen and the near-to-eye optical system can adjust the axial distance between the near-to-eye display screen and the near-to-eye optical system, so as to adjust, namely, increase or decrease the diopter of the near-to-eye optical system; at the same time, the interocular distance adjustment device between the two sets of the near-to-eye optical systems can be used to increase or decrease the optical axis distance between the two sets of the near-to-eye optical systems, so that the optical axis distance is the same as the interocular distance of the human eyes 9 to achieve the effect of adjusting the interocular distance; the image processed by the action of the above device is clearly mapped on the display screen designed in each set of the near-to-eye optical systems, so that the virtual scene formed after enhancement processing is projected into the eyes of the observer.

[0041] Transmission of image information:

[0042] the device acquisition end transmits the enhanced image from the independent image data channel or the combined image data channel to the image information receiving unit of the device reproduction end through wired or wireless transmission of the transmission device; after receiving the enhanced image information, the image information receiving unit separates the image information transmission channel and imports it into the display channel corresponding to the transmission; the image information receiving unit imports the image information corresponding to the display channel into the image enhancement unit 10, and imports it into the near-to-eye display screen after the enhanced image obtained; after the enhanced image is displayed by the near-to-eye optical system, using the diopter adjustment device located between the near-to-eye display screen and the near-to-eye optical system can adjust the axial distance between the near-to-eye display screen and the near-to-eye optical system, so as to adjust, namely, increase or decrease the diopter of the near-to-eye optical system; at the same time, the interocular distance adjustment device between the two sets of the near-to-eye optical systems can be used to increase or decrease the optical axis distance between the two sets of the near-to-eye optical systems, so that the optical axis distance is the same as the interocular distance of the human eyes to achieve the effect of adjusting the interocular distance; the image processed by the action of the above device is clearly mapped on the display screen designed in each set of the near-to-eye optical systems, so that the virtual scene formed after enhancement processing is projected into the eyes of the observer.

[0043] As shown in FIG. 6, the realization method of stereoscopic vision transposition of image information is as follows:

[0044] the parameter configuration of the acquisition end and the reproduction end of the device is consistent, so that the functions of the acquisition end and the reproduction end are completely interchangeable, that is, the above transmission path can be from the acquisition end to the reproduction end, or from the reproduction end to the acquisition end; at this time, the function of the acquisition end becomes the function of the reproduction end, and the function of the reproduction end changes to the function of the acquisition end;

[0045] After receiving the image information, the reproduction end displays the images collected by the acquisition end to the corresponding near-to-eye optical system as a virtual scene 5 for the human eyes to observe. The observer can feel the enhanced scene 2 by the enhanced object light 4, so as to realize the visual transposition technology effect of the real three-dimensional reproduction of the remote scene.

[0046] Combined with the image acquisition and visual enhancement, and the image information transmission method of the above smart wearable device, the transmission path of the image information is changed, and the image information is enhanced and transmitted; through the transmission and copying functions of the image information of the device, one collection end can correspond to multiple reproduction ends, thereby realizing the visual transposition of the smart wearable device, so that the virtual scene formed after enhancement processing can be projected into the eyes of the observer.

[0047] The invention allows the observer to see the displayed image and also see the real external environment image through the system; the field angle of the camera lens on the single side is matched with the field angle of the near-to-eye optical system, and the ratio of the field angle is doubled or other magnifications; the camera lens on the single side images the real scene onto the image sensor through the real object light 3; after the image sensor collects the real scene image in the dark environment, the virtual scene is displayed through the near-to-eye optical system corresponding to one side; the observer can see the enhanced scene corresponding to the real scene by observing the virtual scene displayed by the near-to-eye optical system; when more than one set of visual enhancement systems work on the same real scene, by adjusting the appropriate optical axis angle, the stereoscopic visual enhancement effect can be achieved.
