In light source performance, light source assembly 7 adopts great power LED by inside, drive of constant voltage source scheme in the past can not ensure the concordance of LED luminance, and affect reliability and the life-span of LED, therefore we adopt constant-current source to drive, in order to avoid the luminance deviation using the components and parts accuracy error under pure hardware constant-current to cause, add and adopt pid algorithm to form closed loop feedback based on DSP, ensure that intensity of illumination and the output accuracy of LED.Meanwhile, add human-computer interaction interface 4 and control button 3, the adjustment of brightness can be carried out according to different cavity environment and object.

Referring to Fig. 5, for the Systematical control block diagram of this PID feedback control, I is given current values amount, and i is actual current signal, by dsp chip AD port by the actual current numerical quantities IA obtained that samples, EI is the deviate of setting value and actual value, carries out computing by PID to the deviate of feedback control system, because the sampling period is very short, integration is replaced with summation, difference coefficient replaces difference quotient, makes pid algorithm discretization, thus becomes difference equation by the differential equation.

In this constant current source driving circuit, by gathering, A/D conversion, pid algorithm control, and makes electric current form closed loop system, thus generate pwm signal, the break-make of gauge tap pipe, keep electric current constant.The temperature drift impact that can effectively suppress LED to bring along with fluorescent lifetime increases, ensures the constant output of current value.

In addition, structurally, if light source assembly 7 internal main is made up of optically focused module, the structure of optically focused module as shown in Figure 3, be made up of four pieces of convex lens sheets, 8,10,14,17 and 1 pieces of infrared filtering eyeglasses 12, the astigmatism of LED is aggregated into intensive strong beam by convex lens sheet, and by infrared filtering eyeglass 12 filtering infrared wavelength wherein, prevents ultrared photothermal deformation.Wherein 9,11,13,16 is the accurate spacer ring of aluminum alloy materials, and surface is attached is coated with reflector layer, reduces light absorption.Optically focused module shell 15 adopts with bonnet 19 and is threaded, and accurate spacer ring 9,11,13,16 and eyeglass 8,10,14,17 is fixed in inner ring.The phase tangent plane of bonnet 19 there is straight-through screwed hole, connects fastening rear employing and hold out against screw 18 and by screwed hole, whole optically focused module is reinforced, prevent extraneous vibration from causing relative movement between optically focused module shell 15 and bonnet 19.

In image procossing: one is adopt to improve picture display rate based on the mode of the two-wire journey of DSP, its thread 1 for image collection and extract effective view data, thread 2 carries out the process of image, display and storage; Two is possessed a series of image processing algorithm function, comprise color correction, contrast strengthen, white balance, metering mode, emphasizing contour etc., especially for the drawback of color correction implementation in the past, propose the color correction algorithm of the four neighborhood polynomial regression based on YUV color space:

The mode of conventional color correction adopts based on the least square matrix fitting method on RGB color space substantially, but the color of image after these class methods correct can change along with brightness of illumination condition, reduce color of image stability, and create a lot of noise, reduce picture quality, also can affect process and the diagnosis of electron mirror image.The reason of this phenomenon is caused to be based on the least square matrix on RGB color space, $\left[\begin{array}{c}Y\\ U\\ V\end{array}\right]=\left[\begin{array}{ccc}0.3& 0.59& 0.11\\ -0.15& -0.29& 0.44\\ 0.51& -0.52& -0.095\end{array}\right]\·\left[\begin{array}{c}R\\ G\\ B\end{array}\right]$

Fitting process considers R in the process asking fit metric simultaneously, and G, B tri-factors, wherein contain the monochrome information of image, so the color of image after correcting can change along with brightness difference.

In order to avoid this shortcoming, we select on yuv space correct image.In algorithm research, first by camera collection to rgb signal numerical value convert the numerical value of YUV according to the following formula to, polynomial regression matching being carried out to U, V colour difference signal, reference standard colour atla by getting rid of Y (brightness), finally obtaining correction coefficient matrix A.

Owing to there is stronger dependency relation between independent variable in polynomial regression model, we adopt this type of regression model for the regression analysis of algorithm, and relative to using common least square regression, the variable regression system errors of estimation can be less.Because polynomial regression relies on the item number of data fitting, along with polynomial item number increases, regression accuracy improves gradually, but is not that exponent number is higher, and calibration result is better.Item number can cause image quality decrease on the contrary too much to such an extent as to lose too many details.Therefore, in this algorithm, we adopt U, and V, UV tri-carry out fitting of a polynomial, and try to achieve correction matrix, specific implementation method is as follows:

Then realized the U of the standard to colour atla by the linear combination of U, V, UV to the imaging of standard color card electron mirror according to polynomial regression ₀, V ₀, U ₀v ₀component carries out matching, and expression is as follows:

$\left\{\begin{array}{c}{U}_0=a_{11}U+a_{12}V+a_{13}\mathrm{UV}\\ V_0=a_{21}U+a_{22}V+a_{23}\mathrm{UV}\\ U_0{V}_0=a_{31}U+a_{32}V+a_{33}\mathrm{UV}\end{array}\right\}$

The matrix form of above formula is:

X＝AW

Wherein X is standard U, V, UV component formation 3 × 24 dimension matrixes of each color lump getting standard color card:

$X=\left[\begin{array}{c}\left|\begin{array}{cccc}{U}_{01}& U_{02}& ...& U_{024}\\ V_{01}& V_{02}& ...& V_{024}\\ {\mathrm{UV}}_{01}& {\mathrm{UV}}_{02}& ...& {\mathrm{UV}}_{024}\end{array}\right.\end{array}\right]$

W is that U, V, UV component that standard color card electron mirror actual imaging records forms 3x24 dimension matrix:

$W=\left[\begin{array}{c}\left|\begin{array}{cccc}{U}_{I1}& U_{I2}& ...& U_{I24}\\ V_{I1}& V_{I2}& ...& V_{I24}\\ {\mathrm{UV}}_{I1}& {\mathrm{UV}}_{I2}& ...& {\mathrm{UV}}_{I24}\end{array}\right.\end{array}\right]$

Derived by principle of least square method:

A＝X·W ^T·(W·W ^T) ^-1

The model parameter that matrix A is namely required, wherein, subscript T representing matrix transposition, subscript-1 representing matrix inverse, the conversion coefficient matrix of A to be dimension be 3x3:

$A=\left(\begin{array}{ccc}{a}_{11}& a_{11}& a_{13}\\ a_{21}& a_{22}& a_{23}\\ a_{31}& a_{32}& a_{33}\end{array}\right)$

Adopt above-mentioned steps to standard U, V, UV value of x-rite (Ai Seli) 24 color color standard test chart and test the color correction relational matrix A that U, V, UV value calculates this system according to the following formula:

$A=\left(\begin{array}{ccc}0.625354& -0.44687& 0.007002\\ -0.436& 1.210023& 0.002679\\ -113.069& -59.0324& 2.366034\end{array}\right)$

Calculated by matrix A and obtain new U, V component after correcting.

Secondly four art processes process are adopted to Y luminance signal.Suppose that i is for row, j is row, four neighborhood coordinates i.e. (i, j), (i, j+1), (i+1, j), (i+1, j+1), obtain the numerical value of average R, G, B of these 4 pixels, change according to the conversion formula of above-mentioned RGB and YUV numerical value, draw the meansigma methods of 4 pixels of Y luminance component.

So far we obtain the correction data of YUV, corresponding rgb value is tried to achieve again by reverse conversion formula, finally at the existing encryption algorithm of utilization, 8 bit data (the every roadbed chrominance signal in R, G, B) are encoded to 10 bit data (comprising row field synchronization information, clock information, data DE, error correction etc.) by minimum transition, after DC balance, adopt differential signal transmission data, one tunnel shows eventually through LED display 23, digital visual interface (DVI interface 25) of separately leading up to exports

Realize the correction of the picture color under electron mirror.

Except image processing function, this equipment is based on the multithreading basis of DSP also being recorded the modular circuit such as (keyboard 22), WIFI (WIFI module interface 24), 3G/4G on H.264 basis, have employed advanced H.264++ video compression algorithm, streaming media video data compress technique wireless-transmission network solution, incorporate WIFI, 3G/4G data communication facility and digital video coding function is integrated.Realize mutual, transmission, the encryption and decryption of video data, add decoding, the functions such as the control maintenance of link.According to application, Real-time Motion Image is passed on the cloud server of communication network, user can connect cloud server by PC, intelligent communication device and obtain real-time image information, achieves a series of functions such as the remote diagnosis of medical Internet of Things, remote teaching and long distance monitoring.
