Embodiment
Accompanying drawing discloses the concrete structure of the embodiment of the invention without limitation, below in conjunction with accompanying drawing the present invention is done to describe further.
As seen from Figure 1, comprise camera 1, seeder 4, travelling belt 3 and PC 6 compositions in the system, wherein: travelling belt 3 is through the below of a pair of camera 1, travelling belt 3 tops between a pair of camera 1 are provided with seeder 4, the output signal of two cameras 1 is connected with PC 6, contains image processing software in the program of PC 6.In the use, travelling belt 3 drives camera 1 below that the seedling dish 5 that contains the seedling cave enters inlet end, camera 1 at first obtains the image information of the preceding seedling dish 5 of sowing, be recorded in PC 6 by image processing software, when seedling dish 5 enters seeder 4 belows, seeder 4 begins sowing, run to camera 1 below of endpiece when seedling dish 5, camera 1 will obtain the image information of this seedling dish 5 after planting, compare by the image processing software and the image information of preceding this seedling dish 5 of sowing by PC 6, and calculate each cave and on average sow a number, the uniformity coefficient qualification rate, indexs such as leakage sowing rate and replay rate show or print result then.In order to improve the quality of image information, camera watch region also should dispose light source 2.
During concrete enforcement, the dominant frequency of the CPU of described PC is at least 1.0GHZ, and internal memory is at least 256MB, and hard disk is 20G at least.The described image processing software that can adopt detects identification software for the super rice seeding quality.The seedling cave of seedling dish 5 is a rectangle, described seedling cave in length and breadth proper alignment in seedling dish 5, the size of seedling cave length and width size is horizontal by rice transplanter in the subsequent production, vertically the seedling taking amount is determined, is the seedling pawl seedling taking area of rice transplanter, and this value can change flexibly according to producing needs.
By Design of software The general frame (Fig. 2) as seen, super rice seeding quality detection identification software comprises following content:
Input and output: finish the functions such as opening, withdraw from of software, can link to each other with printer in addition, testing result data or graphic printing are come out;
Pre-service: the picture that input is collected becomes gray-scale map, and the photo before and after will sowing does calculus of differences, removes background, by means such as filtering, burn into expansions the noise remove in the target image fallen simultaneously, obtain having only the image of kind of sub-goal, lay a solid foundation for carrying out graphical analysis.
Graphical analysis: extract and the area of seed extracts information such as the edge that obtains paddy rice in every seedling cave, area by rim detection, profile.
Iamge description: according to gained image situation, analyze the parameter of paddy rice in every seedling cave, select calculative parameter, for example: area, girth, the long and short axial length of major axis or the like according to actual conditions.By calculating the gained parameter, according to the scope of demarcating in advance, judge the sowing situation in every seedling cave, there are several seeds in promptly every seedling cave.
The result shows: above-mentioned judged result is showed with form or diagrammatic form, and statistical computation goes out indexs such as corresponding average particle number, replay rate, leakage sowing rate, qualification rate.
Help:------provides the usage information of each button in the software to index; About------provides software developer and information of software explanation.
As seen from Figure 3: in practice, system is work like this:
Image acquisition: with camera collection to image be sent to computing machine;
Background segment: remove background, obtain the rice paddy seed target;
Remove noise: remove the noise except that seed in the image;
Seed characteristics is extracted: the image information of extracting seed characteristics and every cave;
Setting amount of broadcasting and seedling taking area: determine every dish amount of broadcasting according to agriculture requirement, according to horizontal, the machine-direction oriented calculating seedling taking of rice transplanter area, promptly every cave size.
Discern every seedling cave seed amount: according to a seedling cave seed information that extracts, it is sowed seed information with known standard compare, determine this seedling cave rice paddy seed number.Judge this seedling cave rice growing quality of seedling dish according to setting the seedling taking area then, for example: one to two paddy rice in a cave is qualified, for replaying, is lower than one and is broadcast leakage, and the result is preserved more than two.Scan next cave then, successively circulation.
Statistical study: every bunch planting kind situation of all preservations is done one gather, the whole sowing of statistics qualification rate, replay rate, leakage sowing rate etc.
The result shows: statistics is shown with figure or form, can print or subsequent operation such as preservation.
