Description
Technical field
The present invention relates to medical instrument, in particular to a kind of camera beaded support for tongue body three-dimensional reconstruction.
Background technique
Lingual diagnosis is very important content in tcm inspection, and traditional TCM tongue diagnosis observes by the naked eye the tongue to patient
The information such as shape, tongue fur, tongue color and coating colour, coating nature are analyzed and determined that this personal experience for judging to tend to rely on doctor lacks
Weary objective data judgement restricts the succession and development of lingual diagnosis.In recent decades, the research that objectifies of lingual diagnosis is by universal weight
Depending on, but the emphasis studied is concentrated mainly on based on two-dimentional tongue image and video analysis tongue characteristic, three-dimensional of the scholar to tongue body
Research in terms of feature extraction is less.
With the fast development of computer technology, the application in terms of computer vision field also has very wide prospect.Three
It is to establish corresponding three-dimensional stereo model by data processing using two-dimensional image information that dimension, which is rebuild, multi-vision visual method be using
Multiple cameras are arranged multiple viewpoints or single camera and observe 3-D image from multiple viewpoints, obtain image sequence.Based on more
The tongue body three-dimensional acquisition visually felt be exactly the real world that will be got under multiple visual angles tongue body image by camera calibration,
Data processing, Stereo matching, point cloud acquisition and etc. obtain the three-dimensional stereo model of tongue body.
Many researchers based on multi-vision visual three-dimensional acquisition and the tongue body aspect that objectifies have made intensive studies and phase
It closes and attempts, and achieve certain achievement.Existing tongue mostly discharges picture pick-up device horizontal alignment, tongue as three-dimensional reconstruction mode
It is lacking in terms of acquisition of information.
Summary of the invention
The purpose of the present invention is overcoming deficiency in the prior art, a kind of camera shooting head shoot for tongue body three-dimensional reconstruction is provided

Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
As shown in Figure 1 and Figure 2, a kind of picture pick-up device beaded support for tongue body three-dimensional reconstruction, including spherical shell
1, the hemispherical shell structure of the spherical shell 1, the inner concave of the spherical shell 1 is towards subject's tongue body, arcuate surface court
To lamp source, subject's tongue body is located at the center point of the spherical shell 1, so that each picture pick-up device is just shown in tongue body,
Tongue can utmostly be obtained as information.
As shown in Figure 1, eight centripetal camera holes are offered on the spherical shell 1, to install picture pick-up device.Eight
The camera hole is from top to bottom divided into: two upper layer camera holes 2, four middle layer camera holes 3 and Liang Ge lower layer camera hole 4；Installation
In the upper layer camera hole 2 the picture pick-up device to shoot tongue body upper information；It is installed on the institute of the middle layer camera hole 3
Picture pick-up device is stated to shoot information in the middle part of tongue body；The picture pick-up device of lower layer's camera hole 4 is installed on to shoot tongue
Lower information.Shape to install the camera hole of the picture pick-up device is consistent with the shape of the matched picture pick-up device.
The periphery of the spherical shell 1 is provided with an annulus 6, in place can punch on the annulus 6 and open up screw
The spherical shell 1 is connected by hole by fixed screw with other structures.Assuming that the outer ring radius of the annulus 6 be R_wh,
Inner ring radius is R_nh, and the radius of the fixed screw is R_ls, then, R_wh-R_nh >=2 × R_ls.It is described in practical application
The outer ring radius R_wh=117.5mm of annulus 6, inner ring radius R_nh=107.5mm, the radius R_ls=of the fixed screw
2mm。
The back side (i.e. arcuate surface) of the spherical shell 1 is provided with gasket 5 around each camera hole, uses
With the fixation picture pick-up device.Set 5 spacing of gasket should be with the via hole of the picture pick-up device around each camera hole
Spacing is equal, to fix picture pick-up device.It is assumed that the spacing of gasket 5 set around each camera hole is L_dp, it is described
The mistake pitch of holes of picture pick-up device is L_gk, then should meet relational expression L_dp=L_gk.In practical application, the spacing of the gasket 5
L_dp=38mm, the mistake pitch of holes of the picture pick-up device are L_gk=38mm.
The sheen region to simulate natural light is provided on the spherical shell 1.The sheen region is less than for thickness
The region of 1 integral thickness of spherical shell.The sheen region is provided with several, and the center of circle with the spherical shell 1 is
Origin, if transverse direction is x-axis, longitudinal direction is y-axis, several described sheen regions are not only symmetrical about x-axis but also about y-axis
Symmetrically.The position in the sheen region and size do not limit, and satisfaction does not influence to play while 1 intensity of spherical shell
The effect of light sheen.As shown in Fig. 2, in practical application, in a lateral direction with item at six is provided on longitudinal direction altogether
Shape sheen region 7 is provided with fan-shaped sheen region 8 everywhere altogether on oblique direction.
The material of the spherical shell 1 should have certain intensity, so that being unlikely to deform after shaping, reduce three-dimensional reconstruction
When error.It is H_zt that the spherical shell 1, which designs its integral thickness,.In order to guarantee uniform illumination, its sheen region is designed
With a thickness of H_rg.In practical application, the spherical shell 1 is printed using photosensitive resin material.Photosensitive resin material, again
Name light-cured resin, is widely used in 3D printing, this kind of material viscosity is low, and swelling is small, and error is small after finished product, and light sensitivity is high,
Quick solidifying, it is possible to reduce the contraction of curing molding model, so that curing deformation after reducing, can guarantee the precision of model.The ball
The integral thickness H_zt=2.5mm of shape shell 1, the thickness H_rg=1mm in sheen region.
The size of the spherical shell 1 should be suitble to picture pick-up device to acquire, and guarantee that tongue body completely appears in each picture, and
Tongue is clear as details.Assuming that the radius of the spherical shell 1 is R_zj.In practical application, the radius R_zj of the spherical shell 1
=125mm.
The equipment such as industrial camera or camera mould group can be selected in the picture pick-up device, it is desirable that when resolution ratio should reach the diagnosis of tongue picture
Required resolution ratio, i.e. details are clear, can guarantee that the image procossing of subsequent tongue picture is normally carried out.The data line being attached thereto should be selected
With sets of data lines, guarantee the undistorted transmission of data.In practical application, select product type for the camera shooting of 3038-8828AF V1 type
Head, and select it with sets of data lines, guarantee the undistorted transmission of data.This kind of camera is integrated with conditioning circuit, can be realized
Auto-focusing shoots image having a size of 2048*1536, meets application demand.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited to upper
The specific embodiment stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
Technical staff under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, may be used also
By make it is many in the form of, within these are all belonged to the scope of protection of the present invention.
