Description
Technical field
The invention belongs to medical equipment, be specifically related to a kind of novel three-dimensional tridimensional electronic hysteroscope system that utilizes many ccd array to carry out stereoscopic image reconstruct.
Background technology
CCD (Charge-Coupled Device, charge-coupled image sensor) is a kind of important component part that can be used for stereoscopic camera.It is a kind of photosensitive semiconductor device, and the photosensitive unit on it is converted to the quantity of electric charge with the light that receives, and quantity of electric charge size is directly proportional with the incident light intensity.The technology of ccd image sensor is very ripe, can be spliced into the array of Any shape as required.Company of Fuji released super CCD technology in 1999, with the situation of common CCD equal area and photosensitive unit number under, its resolution improves 60%, dynamic range improves 130%, color reproducibility improves 40%, and energy consumption descends 40%, has further improved the function of CCD.The photosensitive unit size of CCD is constantly reducing, at present the photosensitive unit size of report having been arranged only is 0.5 μ m, entered the submicron epoch, CCD will further develop round aspects such as high-resolution, high reading speed, low cost, microminiaturization, structure optimization, multispectral application and 3D photograph.But the area array CCD sensed image that the photosensitive unit that matrix is arranged constitutes.CCD is widely used in digital camera and the DV now, also in astronomical telescope, scanner and barcode reader application is arranged simultaneously." Chang'e-2 " uses 96 line ccd array that same target is sampled, and at last signal all added up.The target that very dark target, resolution are very high, " Chang'e-2 " can both break forth, and its resolution can reach 1 meter.
Present employed endoscope, can be divided into monocular and binocular, monocular endoscope is by an optical system imaging, the doctor can directly use eyes to observe by the eyepiece end, but owing to be monocular instrumnent, can only obtain the image of an angle of object, just as using single eyes to see the effect of object, object lacks third dimension and distance perspective.The doctor uses monocular endoscope to undergo surgery, because monocular instrumnent becomes planar image, lacks spatial perception, so need to rely on doctor's technical merit.
Some stereo endoscope, what use is the binocular structure, its endoscope distal end can be a camera lens or two camera lenses, the image of object is by the output of two eyepieces, and the doctor can observe stereoscopic image with the human eye similar object by binocular, also can be by connecting particular processing main frame and display, processing by processing host, can in display, show spatial image, but this image also is single angle, has certain limitation.Though the binocular stereo endoscope can obtain the stereoperception of similar eye-observation object, but because the limitation of human body cavity, the three-dimensional overall picture that can not reflect the whole surgery zone three-dimensionally, so the doctor is when using existing scope to undergo surgery, all to be subjected to visual restriction, certain restriction be arranged for the cure rate of carrying out and improve disease of performing the operation.
In the prior art, also the ccd array notion is not combined application with hysteroscope, therefore,, design a kind of that many ccd array technology and the bonded endoscopic technic of hysteroscope is extremely urgent in order to obtain in the uterine cavity 3 D stereoscopic image clearly.
