Abstract
A stereoscopic endoscope, especially a virtual reality stereoscopic endoscope for synthesizing images by dual optical paths and time sharing in shift parallax method, is composed of optical prism, camera and image processor, which is connected to the helmet of stereoscopic vision.
Description
The present invention relates to a kind of endoscopic technique, the 3-D visual endoscope of the synthetic virtual reality of particularly a kind of displacement parallax method double light path Time Index Chart picture.
Endoscopic technique is widely used as a kind of imaging observational technique, still all plays an important role in commercial Application in medical science.Endoscopic technique is constantly development in application, is example with the medical science human body with endoscope, has rigid, soft, thick type, thin type etc. multi-form.But generally speaking endoscope is divided into three parts: part is observed in (1) object lens (2) conduction pipe shaft (3) eyepiece and imaging.The imaging technique that uses mainly contains imaging pricker technology and electro-photographic imaging technique two big classes at present.Imaging pricker type endoscopic technique occurs early, and it is to obtain the observation image by object lens and luminaire, and image is transmitted to the eyepiece end by the imaging pricker in the conduction pipe shaft, and the people can observe image by eyepiece.Electro-photographic imaging endoscope technology is a kind of endoscope new technique that grows up along with development of electronic technology in recent years.Its operation principle and imaging pricker type endoscope are identical, just change object lens into video camera, change the light conducting pricker into electric wire, change eyepiece into television imaging equipment.
Various endoscopies that all are used at present are medical or commercial Application on all with identical working method work, only obtaining one road image from endoscope distal end is monocular vision figure.Medical science human body inspection some common ulcer focuses of splanchnoscopy commonly used for example are recessed or protrudingly to come in to judge that focus is benign or pernicious canceration according to patient's ulcer surface.And present various endoscopies use the monocular vision image, and the observer does not have distance perspective, therefore except some spies except that case, can't make concavo-convex judgement generally speaking.Task of the present invention provides a kind ofly has the binocular stereo vision endoscope of more actual distance sense to the observer, thereby makes the doctor can accurately judge the concavo-convex situation on focus surface.
Technical scheme of the present invention is: 3-D visual endoscope, particularly displacement parallax method double light path Time Index Chart picture synthesizes the virtual reality 3-D visual endoscope, this endoscope comprises optical prism [1], miniature shifting sledge [2], observation window AB[3], object lens [4], leaded light imaging fibre [5], eyepiece [6], video camera [7], lead [8], the image synthesizer [9] and the stereoscopic vision helmet [10], it is characterized in that endoscope's optical prism [1] is fixed on the miniature shifting sledge [2] that can move forward and backward, utilize the optical prism [1] of the mobile endoscope head of miniature shifting sledge [2] to arrive observation window AB[3], enter leaded light imaging pricker [5] through object lens [4], eyepiece [6] and video camera [7], and by lead [8] the connection image synthesizer [9] and the stereoscopic vision demonstration helmet [10], thereby be shown to about the observer two simultaneously at two width of cloth images that diverse location obtains different visual angles with timesharing, make its two to produce spatial visual effect by two width of cloth figure images.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of 3-D visual endoscope of the present invention.
Endoscope is made up of optical prism 1, miniature shifting sledge 2, observation window AB3, object lens 4, leaded light imaging pricker 5, eyepiece 6, video camera 7, lead 8, image synthesizer 9, the stereoscopic vision demonstration helmet 10 among Fig. 1.Optical prism 1 is installed on the miniature shifting sledge 2, and the optical prism 1 that utilizes micromachine to move forward and backward endoscope head arrives observation window AB3.This miniature shifting sledge 2 is to add slide rail with miniature automatically controlled coil tension spring to make, and this machinery also can be made by the plant equipment of other type, as long as finish above-mentioned functions.Observation window AB3 makes with transparent material.Install may command additional at endoscope's optical prism 1 with above the object lens 4 and carry out the optical system that two points move, obtain image respectively, be equivalent to the people and close right eye and have a look at, have a look at right eye conversely again with left eye at two location point AB.These two location point spacing certain distances, the anaglyph that two similar people that therefore obtain respectively on two location points two.Connect eyepiece 6 and video cameras 7 by leaded light imaging pricker 5, video camera 7 can be with ccd video camera or other type electron camera.Video camera 7 connects image synthesizer 9 by lead 8 and stereoscopic vision shows the helmet 10.The image of two same targets that contains parallax is synthetic by image synthesizer 9, then difference is obtained constantly two width of cloth images by stereoscopic vision show the helmet 10 be shown to respectively simultaneously the observer about two, thereby produce stereoscopic vision.
1. the enforcement of imaging pricker type endoscope binocular stereo vision: before before object lens, installing
The described miniature shifting sledge of literary composition can move to camera lens respectively two of AB
Ad-hoc location.Add video camera in the eyepiece rear end, the image that the conduction of light pricker is come changes
Change into electronic image, the view picture at the AB two positions is stored respectively, right
After by the virtual reality vision helmet AB two width of cloth images are shown respectively simultaneously
Give the people about two, finish the stereoscopic vision imaging.
2. the enforcement of electro-photographic type endoscope binocular stereo vision: in imaging pricker type
Sight glass is similar, just because therefore its existing electronic camera system need not reuse
Electron camera.Microminiature moving device is installed, former endoscopic system before object lens
Electron camera in objective end need not change, and the video camera that install at this place only needs straight
Agree to play to take the photograph getting final product, the electron camera at objective end place carries out the electronic image that transmits
Synthetic, the demonstration of storage.
The invention has the beneficial effects as follows by the displacement parallax method to make endoscope have the stereoscopic vision ability that this method is suitable for the most endoscopes system.The doctor judges the concavo-convex of focus surface with this invention technology, and endoscope's diagnostic techniques is had very big impetus, and endoscope's little invasive procedures middle distance sense surgical action is crucial accurately especially.In commercial Application, utilize endoscopic system that precision equipment is carried out the inside maintenance, distance perspective can reduce maintenance difficulty greatly accurately.
