Description
Technical field
The present invention relates to laver processing machine tool technical field, be specifically related to a kind of DSP of application image processing techniques carries out automation sorting device to laver.
Background technology
Laver processing industry and coastal area fishery economic develop closely bound up, and its development degree also can reflect the level of economic development of coastal area.The sheet Zhang Pinxiang of laver time processing determines its height of concluded price in laver trade market.In laver time processing process, the sorting operation that dry laver sheet is opened is then make a final check to the quality with a collection of product.As can be seen here, sorting operation meaning great of dry laver.
The defect of the dry laver of standard square mainly contains: hole, foreign matter and profile.In production, dry laver has foreign, the number of hole and size, and the unfilled corner of profile, scarce limit or crack are used as the partitioning standards of quality grade.
Superfine require square plate open smooth, thickness evenly, neat in edge, without breakage, stiff spot, chrysanthemum spot, hole and extremely spot; One-level require sheet open smooth, thickness evenly, neat in edge, without chrysanthemum spot and dead spot, allow have below 2mm hole 3-5 individual in no more than 5%; Secondary requires that sheet Zhang Jiben is smooth, thickness comparatively evenly, neat in edge, allow in no more than 5%, there is the unfilled corner of below 5mm, lack limit or crack, no more than 4 of below 3mm hole; Three grades to require sheet to open more smooth, thickness comparatively even, allows there is the unfilled corner of below 10mm in no more than 5%, lacks limit or crack, no more than 4 of below 3mm hole; Level Four require sheet Zhang Houdu comparatively evenly, have obvious wrinkle, chrysanthemum spot, dead spot, hole and other do not affect edible various defects.
At present, the sorting work of laver mainly still relies on artificial visually examine.Traditional method for separating inefficiency, waste time and energy, processing cost is high, the automation requirement of production can not be met, be unfavorable for the development of laver processing industry.Along with produce increasingly automated and to product quality require raising day by day, in laver process, just must use more effectively, more accurately, more high speed, low cost automatic sorting means.
CCD(Charge Coupled Devices Charged Couple) device from late 1960s occur since, linear good with it, quantum efficiency is high, dynamic range is large and the advantage such as the double digitlization of simulation, has played huge effect in signal transacting and image sensing area.So far the research of CCD device achieves breakthrough, and CCD has been widely used in the aspects such as video camera, duplicator, fax, image recognition.CCD structurally divides line array CCD and area array CCD, and relative to area array CCD, line array CCD instrument has the advantage such as high-resolution, high speed, is suitable for high accuracy, needs the working environment of high-speed capture.Linear array CCD camera obtains target information by camera optical system, by the ccd sensor on its focal plane under the driving of power pack work schedule, optical signalling converted to the corresponding signal of telecommunication, is exported by image acquisition hardware.
The view data collected also needs to process targetedly before practical application, in addition in order to effective transmission information in real time, must compress, so image processing techniques is treated as key technology especially in real time to image.
The major way realizing image procossing has: (1) uses software simulating image procossing on a general-purpose computer; (2) in general-purpose computing system, special acceleration processing module is added; (3) general single chip is utilized; (4) dsp chip is utilized.In numerous processing mode, the most frequently used is the 1st kind, but this mode speed is relatively slow, is unsuitable for real-time process; 2nd kind of mode is unsuitable for Embedded Application, highly professional, for being restricted; 3rd kind of mode is suitable for the Digital Signal Processing that digital control grade is not too responsible for, and is not suitable for calculating larger image real time transfer; 4th kind of mode, developer can very easily to logical dsp software being utilized to design, encode, compile, debug, follow the tracks of and real time analysis.In general, utilize general programmable dsp chip to realize image procossing and than other several modes, there is larger superiority, the programmability of dsp chip and powerful disposal ability, make it can be used for realizing various digital signal processing algorithm fast.Programmable universal type dsp chip is applied to laver scan picture, replaces traditional artificial separation.
