The objective table is positioned between the two plane reflecting mirrors, an object is placed on the objective table, three surface images of the object can be obtained from top to bottom by one-time photo taking with one camera, so that relative movement and deformation of the objects generated by photo taking to various side surfaces of the objects are avoided, and the time of taking photo is saved. The multi-angle imaging device has the advantages of simple design and structure, convenient operation, low cost, small volume and convenient carry, and can be widely applied in the fields of medical imaging and the like.
Description
Technical field
This utility model relates to a kind of multi-angle imaging device, exactly, relates to a kind of device that utilizes plane mirror to object a plurality of sides imaging, and this device can be used to obtain three-dimensional object surface information.
Background technology
Along with developing rapidly of genomics, protein science and disease gene group, the diagnosis of disease is characterizing from traditional disease and is observing, conventional biochemical test detects, develop into the microscopic feature understanding of several genes and molecular level, wherein utilize the molecular image technology can be from generation, the evolution of gene, protein level heightened awareness disease, can realize integral body, continuous, noninvasive special detection method that existing micro analysis institute can't replace, biology will provide brand-new prevention, diagnosis and treatment means in body molecular image theory and technology thereof.With traditional medical image technology comparatively speaking, the basis that molecular imaging is conceived to constitute disease or pathological changes changes and gene molecule level unusual, rather than the final result that is made of the gene molecule change is carried out imaging.Under the help of special molecular probe, the molecular image technology can realize the noinvasive Real-time and Dynamic imaging in vivo of organism internal physiological or pathological process on cell, gene and molecular level, thus for researchs such as the mechanism of action of disease related gene functional localization, cell growth promoter and mutation process, new drug development provide detailed qualitative, location, quantitative data and effectively information obtain means with analyzing and processing.
The autofluorescence tomography technology is the emerging in recent years interior optical molecular image technology of living animal body.Archebiosis fluorescence is with luciferase gene labeled cell or DNA, and the Fluc gene integration is gone up with expressing luciferase to cell chromosome DNA.Under the situation that ATP and oxygen exist, if inject the substrate fluorescein to living animal, the oxidation reaction that luciferase will the catalysis fluorescein also produces photon.External at living animal, utilize highly sensitive optical detecting instrument, can directly capture the outer photon of effusion animal body, utilize effective fluorescence light source algorithm for reconstructing then, just can obtain the position and the intensity of fluorescence light source in the body, and then can observe intravital cell behavior of living animal and gene behavior.
In order as often as possible to obtain overflowing the outer photon information of animal body, need carry out imaging to the three-dimensional surface of animal body with photoelectric detector.At present, the method of utilizing plane mirror to obtain the three-dimensional surface information of animal body has a lot, a kind of method is for using and object plane mirror at 45, successively to the object side surface imaging, this quadrat method has many drawbacks, as: every shooting is once, all to adjust the relative position of primary event mirror and object, so not only the operation trouble is lost time again, the relative position of object changes again easily, to realizing that image Reconstruction has increased adverse factors, and the optical information on animal body surface is along with the time decay, and this reconstruction error is just bigger.A kind of method is for using four plane mirrors, be placed on around the object, and with object angle at 45, obtain four profiles of object simultaneously, the shortcoming of this method is that the picture that becomes on CCD of object is little, and reconstruction error is big, and the image of CCD last 3/4 and body surface information are irrelevant, caused insufficient utilization of CCD, the waste resource.A kind of method is taken pictures to around the object simultaneously for using four cameras, increased the expense of equipment like this, and the performance of four cameras is incomplete same, has increased the error of rebuilding.
The related three-dimensional imaging data acquisition device of this utility model just can obtain three surface informations of object by using a camera once photo taking, and the image of three faces is form side by side, has increased the utilization rate of CCD.
The utility model content
The purpose of this utility model is the drawback that overcomes existing mirror imaging system, provides a kind of and both saves time, and can make full use of CCD again, simple, convenient multi-angle imaging device.
For achieving the above object, this utility model adopts following technical scheme: a kind of multi-angle imaging device includes: plane mirror group, object stage and camera, as shown in Figure 1, camera is positioned at the top of plane mirror group, and wherein camera is a kind of photodetector.The plane mirror group comprises two plane mirrors, two plane mirrors are positioned over the testee left and right sides, reflecting surface at an angle of 90, and respectively with horizontal plane angle at 45, object stage is positioned in the middle of two plane mirrors, object is placed on the object stage, two plane mirrors are identical with the testee distance, can obtain three surface pictures of testee by once photo taking, it is characterized in that, the petty action object that body is contained fluorescence light source is put in the position of testee 5 among Fig. 1, and the petty action object is placed perpendicular to paper, and is positioned at the centre of plane mirror 2 and plane mirror 3, its back picture is directly taken by camera and is obtained, its left surface is by plane mirror 2 imagings, and right flank is once taken and can be obtained back picture and left and right side picture simultaneously by plane mirror 3 imagings.
The beneficial effects of the utility model are: by once taking the fluorescence information just can obtain three faces of testee, save time, and fluorescence information is to obtain at one time there is not the influence of fluorescence decay; The image of each three faces that obtain testee is form side by side, has made full use of the area of CCD; It is simple and convenient to take pictures.Information according to three surfaces of measured object that obtain, utilize the fluorescence light source algorithm for reconstructing, can rebuild accurately the position and the intensity of biological tissue's inside fluorescence light source, be the early diagnosis and the early treatment of disease, that the evaluation of curative effect of medication provides is qualitative accurately, location, quantitative data.
