Description
Technical field
The present invention relates to the mapping techniques field of view data, particularly a kind of quick mapping method of oscillograph digital fluorescence images.
Background technology
In digital fluorescence oscilloscope, generate waveform image by fluorescent moieties, the size of its horizontal direction, according to the horizontal resolution of liquid crystal, determines jointly in conjunction with sampling rate and horizontal timebase, the size of vertical direction quantizes according to sample magnitude, is namely determined by the resolution of ADC.Oscillograph generally uses the ADC of 8, and that is, fluoroscopic image has 256 pixels in vertical direction.
At present, the vertical resolution of oscilloscope display screen is much larger than 256 pixels, distribute to the vertical pixel point of waveform viewing area also more than 256, therefore, after display module reads waveform image from fluorescent moieties, also need the amplification carrying out vertical direction to it to process output display again, the waveform image (source images) generated by fluorescent moieties maps the output image (target image) generating display module.
In image mapped process, the method usually adopted has most neighbor interpolation method and bilinear interpolation.
Because target image and source images are not man-to-man mapping relations, therefore there will be the problem that target image virtual borderlines is not integer to source images coordinate time.For a coordinate (x, y) of target image, floating-point coordinate corresponding in source images after mapping is (i+u, j+v), and wherein i, j are nonnegative integer, and u, v are the floating number of interval [0,1].
Most neighbor interpolation method is at target image virtual borderlines to source images coordinate time, and the color of getting the point of the nearest source images of coordinate position accomplishes the color of target image.
Bilinear interpolation is the color obtaining target image according to the ranking operation mapping four points around rear coordinate, the i.e. color value F (x of impact point, y) be (i according to surrounding's coordinate corresponding in source images, j), (i+1, j), (i, j+1), the color value of four pixels of (i+1, j+1) determines, corresponding formula is:
F(x，y)＝(1-u)*(1-v)*f(i，j)+(1-u)*v*f(i，j+1)+
u*(1-v)*f(i+1，j)+u*v*f(i+1，j+1)
In formula, f (i, j) represents the color value that source images coordinate points (i, j) is corresponding.
In image mapped process, the most neighbor interpolation method adopted and bilinear interpolation, all need the size according to target image, coordinate carries out floating-point operation one by one, efficiency is lower, bilinear interpolation more will carry out the weighted calculation of four data points, and operation time is longer, have impact on the refresh rate of waveform.
Summary of the invention
The object of the invention is to overcome or slow down the part at least above-mentioned shortcoming, hereby provide a kind of quick mapping method of oscillograph digital fluorescence images, it has step:
(1) the digital fluorescence images data of fluorescent moieties generation are read by display module, i.e. source image data;
(2) according to the line number M of source image data and the line number N of destination image data, the common multiple K of M and N is calculated;
(3) every a line of source image data is copied K/M capable, generating vertical direction is the view data that K is capable;
(4) every K/N behavior a line group of view data is set up successively,
Vertically, M row one_to_one corresponding of K/N described row group and source image data,
Whether a line that any row in more described row group is corresponding with source image data opposing rows group is consistent,
Unanimously, then vertically get a line of the first behavior target image of described row group,
Inconsistent, then all row in described row group are put summation by turn, then calculating mean value is as a line of target image;
(5) target image exports and display by display module.
Preferably, described K is lowest common multiple.
Preferably, described N is greater than M.
The present invention can read waveform image data and the source image data of fluorescent moieties generation, according to pixel number M, N of the vertical direction of source images and waveform viewing area, calculate lowest common multiple K, then every a line of source image data is copied as K/M capable, extract successively K/N wherein capable and capable by K/N in get a line or merged by all row averages, generate a line of target image; Floating-point operation need not be carried out to the coordinate one by one of target image, achieve the fast mapping of digital fluorescence images, improve the refresh rate of waveform.
Accompanying drawing explanation
Describe these and other aspect of the present invention in further detail now with reference to appended accompanying drawing, it is depicted as currently preferred embodiment of the present invention.Wherein:
Fig. 1 is the workflow diagram of the present embodiment.
Embodiment
Below in conjunction with accompanying drawing and instantiation, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of quick mapping method of oscillograph digital fluorescence images, it has step:
The first step, reads the digital fluorescence images data of fluorescent moieties generation, i.e. source image data by display module.So, source image data then comprises multirow data, and any a line is made up of several coordinate points.
Second step, according to the line number M of source image data and the line number N of destination image data, calculates the lowest common multiple K of M and N.So, K can as the correlation factor making M and N be associated.
