Description

The system of a kind of rice paddy seed quality testing, kind identification and classification
Technical field
The utility model relates to crops and detects recognition technology, particularly, relates to the system of a kind of rice paddy seed quality testing, kind identification and classification.
Background technology
In recent years, a novel intellectual technology has appearred, i.e. computer vision (Computer vision) technology.Computer vision technique can utilize an imageing sensor with human eye functions, obtains subject image, and image transitions is become one and vision related task.This technology relates to spheres of learning such as artificial intelligence, Neurobiology, psychophysics, computer science, image processing and pattern-recognition, be widely used in engineering fields such as industry, agricultural, medical science, military affairs, remote sensing, scientific research and life, can realize huge economic and social benefit.
Wherein, in the agriculture project field, computer vision technique can comprise four aspects: the monitoring and evaluation of material characteristic and animal and plant growth process, the detection of agricultural product, computer vision in the agricultural automation and vision robot, and the adjusting of agricultural resource and assessment; The Computer Vision Detection technology of agricultural product comprises classification, check and classification.The computer vision classification technique of agricultural product comprises: according to excellent different brackets of default rule judgment seed, for example, according to parameters such as the particle shape of rice paddy seed and chalkiness degrees, rice paddy seed can be divided into different brackets.The computer vision inspection technology of agricultural product comprises: make the judgement of " meet and do not meet " according to default standard, for example, the states such as damage, crackle and disease and pest of agricultural product are detected.The computer vision sorting technique of agricultural product comprises: according to default classification the judgement of making " yes or no " is described, for example, xenogenesis grain that mixes in the differentiation cereal and dopant species etc.In addition, computer vision technique is not simply applying mechanically of industrial circle experience in the application in agriculture project field; Because, with regard to research object, industrial products have stable external and bulk properties, the application ratio of computer vision is easier to realize, and agricultural products is an organism, all multifactor restrictions such as temperature, humidity and plumpness can be subjected to, classification, check and classification can not be in same flow process, finished seed.
In China, rice yield accounts for 45% of total output of grain, and especially since China in 1973 took the lead in success realization corss combination, developing rapidly the volume increase contribution of China's grain of hybrid rice was huge; And along with China's population sustainable growth, cultivated area constantly dwindles, and rice yield is the emphasis of agricultural development.But, owing to lack effective seed cleaning equipment, often sneak into other variety seeds and impurity in the hybrid seed, and easy-clear not, rice paddy seed economic worth height in addition, need cost great amount of manpower and material resources that rice paddy seed is screened and removal of impurities, but can't carry out large batch of nondestructive testing and classification, thereby make that the quality index of rice paddy seed is lower the rice paddy seed quality.On the other hand, because rice paddy seed is movable frequent at production of hybrid seeds maturity period typhoon, the typhoon rainy weather increases rice paddy seed easily and splits grain husk, fringe germination, goes mouldy and bacterial bearing rate; Also have, in rice harvesting and process, sneak into other variety seeds and the impurity of easy-clear not unavoidably, have a strong impact on the quality of rice paddy seed, thereby reduce actual the kind with value.
In the prior art,, identify and the plantation evaluation of sub-district, field, carry out the kind identification of rice paddy seed by rice paddy seed evaluation, seedling in order to overcome above-mentioned defective.Wherein, the rice paddy seed authentication method comprises that form is identified and biochemical analysis,, the various chromosomes of rice paddy seed is relied on magnifying glasses and binocular microscope etc. that is, manually identifies the form of rice paddy seed; But, owing to adopt manual type to identify, and can not be too meticulous, can only judge roughly, and human error is bigger.In fact, identify by manual type, annual identification number is also very limited, the cultivar identification of a large amount of rice paddy seeds mainly also relies on seedling to identify and sub-district, field varieties of plant is identified, and seedling is identified and the plantation evaluation of sub-district, field generally must be through long growth cycle, and evaluation speed often can't satisfy the circulation needs of rice paddy seed.In addition, the cleanliness index of rice paddy seed also rests on by artificial sense and discerns judgement and simple statistics, and efficient is lower, and poor accuracy.
As seen, existing rice paddy seed quality inspection and the kind recognition methods of China is difficult to adapt to the quality monitoring of commercial rice paddy seed in batches.In addition, domesticly utilizing computer vision technique to carry out in the crops detection technique, still resting in the research of state algorithm mostly, can not realize rice paddy seed fast, harmless and high-precision quality dynamic monitoring and kind identification.
In sum, in realizing process of the present utility model, the inventor finds to exist at least in the prior art following defective:
(1) cost height: the quality testing of rice paddy seed and kind identification all need to spend great amount of manpower and material resources, and human cost that expends and material resources cost are bigger;
(2) efficient is low: because the limitation of hand labor efficient and the limitation of hand labor amount, and the cycle that seedling is identified and the plantation of sub-district, field is identified is longer, and is in the quality testing and kind identification of a large amount of rice paddy seeds, limited for kind of amount, step is more loaded down with trivial details, makes efficient lower;
(3) precision is low: because there is inconsistency unavoidably in people's vision separating capacity, and accurate not as good as machine, in the quality testing and kind identification of a large amount of rice paddy seeds, poor to the accuracy that the quality testing and the kind of rice paddy seed are discerned;
(4) the volume for the species difficulty is big: because the quality testing of rice paddy seed and kind identification all be unable to do without artificial work, and the hand labor amount is bigger, in the quality testing and kind identification of rice paddy seed in enormous quantities, is difficult to satisfy for kind of a demand.
Summary of the invention
The purpose of this utility model is at cost height in the prior art, efficient is low, precision is low and the volume for the species difficulty is big defective, the system of a kind of rice paddy seed quality testing, kind identification and classification is proposed, to realize that cost is low, efficient is high, precision is high and volume for the species is easy to advantage.
