Embodiment
Reaching example in conjunction with the accompanying drawings is illustrated the portable cereal analyzer based on digital image processing techniques of the present invention.
The present invention has mainly solved the technical matters of two aspects.It at first is the problem that feeds automatically of cereal sample.Cereal is a kind of particulate mixtures of being made up of a large amount of grain, with digital imagery and image process method such potpourri is detected just to mean each grain in the sample is carried out imaging, Flame Image Process and last analysis of statistical data.For this purpose, the digital camera front automatically be carried and be dispersed in to a special dynamo-electric feeding system must one by one with grain in the sample.Only in this way, camera just can photograph all grain or the most grain in the sample.Meanwhile, dynamo-electric feeding system is can't volume too big, otherwise is difficult to guarantee the portability of instrument.The first step of dynamo-electric feeding system running is that the cereal sample is sent into this instrument by a funnel shown in Fig. 1-4.Being of moderate size of this funnel, otherwise sample or do not have the representativeness of tested rice very little, or influence the portability of testing efficiency and instrument too much.The grain that enters instrument feeds device by a custom-designed oscillatory type and sends into skewed slot, distribution grid and rotation platform.This design of structure shown in Figure 2 makes grain evenly scatter, and is up and down not overlapping, thereby makes follow-up automated imaging, Flame Image Process quick and easy.The illumination of grain sample is to be realized by LED plane diffusing panel.Cereal after the test enters a shovel type gatherer so that the recovery of sample or test again.
Be Flame Image Process and data analysis system on the other hand, owing to adopt the Flame Image Process and the analytical algorithm software that are suitable for grain, the analysis of statistical data result that this software can accurately measure size, shape and the color of single grain and provide whole sample makes the present invention can finish the test of several thousand grain in a few minutes.The transmission of the operation of all images disposal system hardware, the synchronous operation of system software and image is finished by a conventional notebook computer and USB interface.
The present invention is that the method that adopts digital imagery, Flame Image Process and mechano-electronic designing technique to combine realizes a kind of portable cereal analyzer.This instrument by electromechanics feed, digital imagery and Flame Image Process and three systems of data analysis constitute.Dynamo-electric feeding system comprise feed funnel, oscillatory type feeds device, skewed slot, distributing disc, rotation platform and gatherer.Digital imaging system comprises LED plane diffusing panel, optical lens, digital camera and control panel.Flame Image Process and data analysis system comprise notebook computer, USB interface, special image processing software and user interface.
Portable cereal analyzer structure based on digital image processing techniques of the present invention includes dynamo-electric feeding system, digital imaging system and Flame Image Process and data analysis system, the grain that enters dynamo-electric feeding system is through the digital imaging system imaging, again with the imaging digital data transmission to Flame Image Process and data analysis system, dynamo-electric feeding system and digital imaging system are to be moved by notebook computer control by image acquisition and system's control circuit board.Described dynamo-electric feeding system includes funnel 1, is being provided with the distributing disc 3 that is connected on the vibrating device 2 below the funnel 1, and the below of distributing disc 3 is provided with the rotation platform 4 that receives grain, and rotation platform 4 comprises chassis 14 and resilient disc 15.The angular velocity of rotation platform 4 is set at greater than the linear velocity of grain on distributing disc 3, helps making the formation Discrete Distribution of grain on rotation platform 4.On rotation platform 4, be provided with scraping blade 7, below rotation platform 4, be provided with gatherer 8.Be provided with digital imaging system above rotation platform 4, described digital imaging system comprises for the LED plane diffusing panel 5 of illumination and the digital camera 6 that is electrically connected with it.
Described distributing disc 3 is by feeding skewed slot 9, control plate washer 13 and dispersion plate 19 combinations, control plate washer 13 is located at and feeds skewed slot 9 and dispersion plate 19 junctions, control plate washer 13 can be adjusted up and down according to the kind of tested grain, makes the grain enter dispersion plate 19 with the form of plane individual layer.On described dispersion plate 19, be provided with the groove of parallel " V " font of multiple tracks, grain is lined up formation in order.
Described vibrating device 2 comprises and feeds the steel spring plate 10 that skewed slot 9 is connected that steel spring plate 10 is connected on the vibrative solenoid 11.
Shown in Fig. 1,2,3,4, the concrete enforcement of dynamo-electric feeding system of the present invention is such: grain by gravity by the grain that is of moderate size by funnel 1 at first enter be connected with vibrating device 2 feed skewed slot 9, through control plate washer 13, the form with the plane individual layer enters distributing disc 19 then.Control plate washer 13 can be adjusted according to the kind of tested grain.The exit portion of distributing disc 19 has multiple tracks parallel " V " font groove, makes grain line up formation automatically, and grain is fallen on the rotation platform 4 by distributing disc 3.Feed skewed slot 9, control plate washer 13 and dispersion plate 19 aggregate erections on steel spring plate 10, and be connected solenoid 11 with certain frequency vibration.Whole vibrating device 2 required power are limited in the reasonable range, and are fixedly mounted on the chassis 12, and these chassis 12 usefulness screws and nut are fixed on the casing of this analysis instrument, in order to get rid of power consumption and spuious resonance.
Because the angular velocity of rotation platform 4 is set to be higher than the linear velocity of grain on distributing disc 3, has guaranteed the formation Discrete Distribution of grain on rotation platform 4.Rotation platform 4 itself is to be made of the resilient disc 15 that a hard chassis 14 and plastic material are made, and this resilient disc 15 is black and anti-skidding, so that the follow-up imaging of grain.The elasticity of resilient disc 15 makes circular lid be close to hard chassis 14, in case this instrument is knocked and when standing upside down grain fall in the instrument.Grain on the rotation platform 4 breaks away from rotation platform 4 after 5 illuminations of LED plane diffusing panel and digital camera 6 imagings via a scraping blade 7, enters gatherer 8 again.Gatherer 8 is the shovel type and can shifts out from analyser and take away, so that the recovery of grain sample or test again.Scraping blade 7 can be by making of metal spring leaf or plastic plate and pressure being provided, and the installation site of scraping blade 7 on rotation platform 4 as shown in Figure 3.Rotation platform 4 is driven by motor and reduction gearing 16, is controlled by elastic coupling 17 and 90 degree gear casees 18.Pass through so structure just, tested grain is spread out fast and full-automatic digital imagery, and guaranteed the miniaturization and the reliability of whole instrument.
All kinds of control signals are connected with notebook computer with system's control circuit board and USB interface by image acquisition with data image signal.All Flame Image Process, data analysis and system's control and user interface etc. are finished by system software, shown in dotted portion among Fig. 1.The analysis of statistical data result that system software can be measured size, shape and the color of each grain automatically, quickly and accurately and provide whole sample.
