By utilizing a principle of plane mirror imaging and light reflection, four side images of an object can be obtained by one camera through two shootings, so that the relative movement and deformation of the object due to sequential shooting for all side surfaces of the object can be avoided, and the shooting time is saved. The multi-angle imaging device has the advantages of simple design structure, convenient operation, low expense, small volume and portability, and can be widely applied to the fields such as 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 four sides information that three-dimensional imaging data acquisition device involved in the present invention just can obtain object by using a camera to take pictures for twice, take pictures at every turn and can obtain the information of two faces of object, and the image of two faces is form side by side, 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 and camera, as shown in Figure 1, camera is positioned at the top of plane mirror group.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 becomes 90 °, and with desktop angle at 45, two plane mirrors are different with the testee distance, take pictures by twice and can obtain four profiles of testee, it is characterized in that, the petty action object that body is contained fluorescence light source is put in the position of testee 8 among Fig. 1, the petty action object is placed perpendicular to paper, and near plane mirror 3, its right flank picture is by plane mirror 3 imagings, and the back picture is directly taken, once take and to obtain back picture and right flank picture simultaneously, at first by plane mirror 3 imagings, imaging is passed through plane mirror 2 imagings to petty action object abdominal part again, and the left surface picture is by plane mirror 2 direct imagings, like this, can obtain petty action object abdominal part and left surface picture simultaneously in the plane mirror 2.Need to change object distance or camera focus in twice shooting process.
The beneficial effects of the utility model are: just can obtain the fluorescence information of four faces of testee by twice shooting, save time, make that the fluorescence decay amplitude is little when taking pictures for twice; The image of each two faces that obtain measured object is form side by side, has made full use of the area of CCD; It is simple and convenient to take pictures, and only needs this multi-angle imaging device position of translation.Information according to four 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.
