Embodiment
The scalar compare of analysis module that a kind of visual quantitative change computer acquisition device, the image file that comprises the collector of gathering the quantitative change moment image, is connected and receives the microprocessor of the image file that collector collects or computing machine with collector, microprocessor is received carry out the image processing module of numerical imaging processing, the predefined standard picture of image after the image processing module processing and computer stored is analyzed.
Adopt the utility model to carry out the image acquisition judgement and can be divided into two big classes, the one, the decision analysis of conventional quantitative change, the 2nd, the decision analysis of RGB color value.
The decision analysis of embodiment one, conventional quantitative change
1, Flame Image Process:
A, image acquisition device are passed to microprocessor with the image that collects, and are converted into the black-and-white two color image by image processing module;
Method: the rgb value that 1. obtains each pixel color of image;
2. getting a value is conversion critical value (threshold values), when rgb value just is converted to black greater than threshold values, otherwise is white.
B, by adjusting the conversion threshold values, make the tool identifiability (promptly reducing image impurity, outstanding quantitative change main body) of image;
Method: change threshold values, repetitive process a is till meeting the requirements.The threshold values adjustment can beginning is formal gather before with artificial judge adjust, also available programs rule of thumb data select (a certain area pixel is that counting of black determined in the ratio of always counting) automatically.
[RGB color value terminological interpretation: RGB is the color mode of coloured light, and R represents red, and G represents green, and B represents blue.Because each all has 256 luminance level levels three kinds of colors, so three kinds of colors stacks just can form 1,670 ten thousand kinds of colors (being commonly called as " very coloured silk ").The RGB pattern is because be by superimposed other colors that forms of red, green, blue.Under this color mode, each primary colors will form a color channel (Channel) separately, and the brightness of color is respectively 256 rank on each passage, by 0-255.Again by a synthetic composite channel--the RGB passage of three monochromatic channel group.The color of image each several part determines by the numerical value on three color channels of RGB.When RGB numerical value was 0, this part was a black; When rgb color numerical value was 255, this part was a white.]

A, microprocessor are chosen contrast scalar collection according to quantitative change grab type (digital instrument reading, displacement, corner or distortion etc.) from the scalar video memory;
Contrast scalar collection---the standard drawing master drawing image set under all kinds quantitative change, press classification such as digital instrument reading, displacement, corner or distortion, maybe can generate in advance the routine package of above-mentioned standard picture according to the set of the quantitative change standard pictures at different levels of acquisition target customization, each image is corresponding with concrete numerical value (parameter) or Status Name.Be stored in database or other storage mediums, be convenient to retrieval and inquisition.
B, the image (calling " collection sample " in the following text) after will handling by the comparative analysis module carry out the degree of conformity probability analysis with the image (calling " standard specimen " in the following text) of contrast scalar collection;
Method: 1. will gather sample respectively and the standard specimen image carries out vectorized process, and be about to the broken line that continuous black image point is converted to width;
2. allow two width of cloth figure carry out overlapping computing, draw and meet probability accordingly.Getting the value that meets concentrated " standard specimen " the pairing parameter of the highest contrast scalar of probability is adopted value, obtains the collection value, finishes collection.
Embodiment two, for the decision analysis of color value
1, Flame Image Process:
A, image acquisition device are passed to microprocessor with the image that collects, and by image processing module acquisition target and standard specimen colour table (colour table that the standard color block of arranging by linear relationship with a determining deviation is formed) to be gathered simultaneously be coloured image;
The mean value of the RGB color value of the pickup area image of b, calculating acquisition target is called " sRGB " in the following text;
2, scalar comparative analysis:
A, by the comparative analysis module, search isochrome zone position coordinate mutually at " standard specimen colour table " image with sRGB;
Method: traversal is taken out the RGB color value of " standard specimen colour table " each color lump, draws the color lump coordinate that equates with sRGB,
