Abstract
The invention discloses a single-camera stereoscopic endoscope system. The traditional advanced endoscope medical imaging equipment at home and abroad can conveniently obtain and store a medical image but has a defect that a doctor can not conveniently and accurately make a judgment due to unavailable direct view of the azimuth, distance, and the like of a focus because the traditional medical image is a plane image. A single-camera stereoscopic endoscope system comprises a stereoscopic endoscope and viewing equipment. Two pictures with a visual angle difference can be partitioned in the image by adding one prism with two base angles of 22-30 degrees in the front of a camera lens of the endoscope, thus a single-camera stereoscopic endoscope is generated. The system views a stereoscopic image in real time by a stereoscopic spectacles television, a display stereoscopic film viewer and a stereoscopic projector which are matched with the system, can conveniently and accurately view the stereoscopic image of the focus in real time, provide accurate observing data for a microsurgery and carry out disposal in real time and greatly improves the medical diagnosis level.
Description
Technical field: endoscope generally is used for being called medical endoscope in the medical treatment, is used for the industrial industrial endoscope that is called.
Background technology: do not have single-camera stereoscopic endoscope system at present both at home and abroad.Endoscope is that will to go deep into the people intravital, thus require deep diameter the smaller the better, therefore have only be only with single-camera stereoscopic endoscope feasible.
Summary of the invention: single-camera stereoscopic endoscope system is made up of single-camera stereoscopic endoscope, eyeglass stereoscopic television set, computer monitor stereo viewer, stereo projector etc.
Description of drawings:
(Fig. 1) adding that before the camera lens of endoscope two base angles are 22 °---30 ° prism can be partitioned into two pictures in image.The image that is absorbed as figure is shown the image that there is subtense angle in two width of cloth on display.
(Fig. 2) be a kind of accompanying drawing of eyeglass stereoscopic television set, by convex lens, prismatical combined lens by amplifying refraction two pictures on the liquid crystal display sheet become people's left eye and the view of apparatus of right eye superposition resembling.
The specific embodiment: single-camera stereoscopic endoscope is a kind of new-type stereo imaging system, is made up of stereo endoscope and evaluation equipment.Because endoscope peeps in will plaing a part,, be generally 20 millimeters so the diameter of endoscope is very little---1.2 millimeters.And the distance of the object that endoscope will observe is very near, is generally several centimetres---several millimeters.We add that before the camera lens of endoscope two base angles are 22 °---30 ° prism can be partitioned into two pictures in image.(see figure 1) is because the big observed distance of endoscope of diameter of lens is a millimeter for the observed distance of the little endoscope of centimetre diameter of lens, so all there is certain subtense angle (this subtense angle is identical with the subtense angle that object is looked in the sight of people's eyes) in two pictures that the endoscope of which kind of diameter is cut apart by prism.Two exist the picture of subtense angle promptly is the basis of stereoscopic picture plane, produces stereo endoscope hereby.
Evaluation equipment mainly is made up of eyeglass stereoscopic TV, stereo viewer, stereoprojection TV.
The formation of the eyeglass stereoscopic TV of stereo endoscope is made of liquid crystal display sheet, prism, convex lens etc.(Fig. 2) by convex lens, prismatical combined lens by amplifying refraction two pictures on the liquid crystal display sheet become people's left eye and the view of apparatus of right eye superposition resembling.
The computer stereo viewer is adopted and is used the same method by convex lens, prismatical combined lens by amplifying refraction two pictures on the computer monitor are become people's left eye and the amplification stereogram of right eye superposition resembling.
The stereoprojection TV is to be fit to the method that many people watch simultaneously, image can be inserted two scialyscopes, adjusts the picture that scialyscope makes one of them scialyscope projected image left side, the picture on another projected image the right.Picture with two scialyscopes superposes on metal curtain then, so just can be with polarised light glasses to watch three-dimensional tv images.
Because stereo endoscope is output as a video image, therefore can record, also playback in computer easily.So our stereo endoscope promptly can be seen real-time stereo image and can see the image of record reproducing again.
The output signal of stereo endoscope deals with---and a signal with two subpictures is divided into two A, B signals that a subpicture is respectively arranged, can on other three-dimensional displays, plays.
The principle of this technology can also be applied in produces on the stereo camera that reaches the close-shot wisp on the real stereoscopic microscope.
Claims (7)
1. adding before the camera lens of endoscope that two base angles are 22 °---30 ° prism can be partitioned into two pictures in image.Because the observed distance of the endoscope that diameter of lens is big is a millimeter for the observed distance of the little endoscope of centimetre diameter of lens, so all there is certain subtense angle (this subtense angle is identical with the subtense angle that object is looked in the sight of people's eyes) in two pictures that the endoscope of which kind of diameter is cut apart by prism.Two exist the picture of subtense angle promptly is the basis of stereoscopic picture plane.Produce stereo endoscope hereby.
2. the formation of the eyeglass stereoscopic TV of stereo endoscope is made of liquid crystal display sheet, prism, convex lens etc.By convex lens, prismatical combined lens by amplifying refraction two pictures on the liquid crystal display sheet become people's left eye and the view of apparatus of right eye superposition resembling.
3. the computer stereo viewer is adopted and is used the same method by convex lens, prismatical combined lens by amplifying refraction two pictures on the computer monitor are become people's left eye and the amplification stereogram of right eye superposition resembling.
4. the stereoprojection TV is to be fit to the method that many people watch simultaneously, image can be inserted two scialyscopes, adjusts the picture that scialyscope makes one of them scialyscope projected image left side, the picture on another projected image the right.Picture with two scialyscopes superposes on metal curtain then, so just can be with polarised light glasses to watch three-dimensional tv images.
5. because stereo endoscope is output as a video image, therefore can in computer, writes down easily, also reset.So our stereo endoscope promptly can be seen real-time stereo image and can see the image of record reproducing again.
6. the output signal of stereo endoscope deals with---and a signal with two subpictures is divided into two A, B signals that a subpicture is respectively arranged, can on other three-dimensional displays, plays.
7. the principle of this technology can also be applied in and produce on the stereo camera that reaches the close-shot wisp on the real stereoscopic microscope.
